Green manures, cover crops and nitrogen fixing trees


Recommended Posts

Hi TT 

You're up bright and early and on the ball as usual !! Afraid my caffiene levels haven't reached their optimum levels yet !!

I knew I should of written it all myself instead of using the old cut and paste :o !!

I take it you're refering to the figures in the quoted text and are comparing it to the amount of urea used in conventional farming I believe urea is usually spread at rates of between 40 and 300 kg/ha I agree that the green manure is very low. Maybe the hairy vetch was a bad example may be other crops produce a greater bio-mass (I'll try and see if there is a green manure here in Thailand giving better results) or perhaps it is simply the case that green manures can't match chemical inputs even slightly !! It definitely bears some further research and as I said I'm gonna try and find out the nitrogen content/ bio-mass etc. of some that are available.

Thanks for pointing this out TT I'll try to read more fully anything I post and especially concerning any maths ( definitely one of my weak points ). I'm also working on a very small scale and talk of hectares and application rates boggle my brain on occasions :D  !! Good to know we have the likes of you to help pick up on these sort of things  :D !!

I think I picked up on the fact that often companies add filler to urea to add bulk to the fertiliser ( possibly from a MaizeFarmer post ) do you have any knowledge you could share on this ?? Obviously it could affect the figures. I found this site nitrogen sources which contained this "Dry pelletized urea is popular as a nitrogen fertilizer compared to other forms because of its relatively high nitrogen content (46% of the total weight is nitrogen), good storage and handling properties, and widespread availability." Any hands on experience or just knowledge you have to help seperate the "facts from myths" would be especially appreciated as I'm starting to get a little out of my "comfort zone" on the matter !!  

 cheers mate J

Hi Foreverford, You might be interested in "stylo" (Stylosanthes guinensis) and in particular the variety "Ubon Stylo". You can buy good quality scarified seed from the Faculty of Agriculture, Unive

Howdy folks. This is the first time posting and would like to find a source to purchase seeds for green manuring. Sesbania Rostrata looks promising for what I'd like to try but am open to anything ava

Gawd....Haha...it's me who needs the caffine jandtaa. Urea is 280% protien and I've gone and used that in the figures.

90lbs nitrogen is 41 kilos urea per acre. Still on the low side. Urea is 46-0-0 NPK. Every 50 kilo bag contains 23 kilos nitrogen.

The rest is just a carrier (filler).

Abject apologies my friend.

Regards.

Ha ha !!

No need for apologies TT !! You did however send me off on a three hour googlethon and a reread of all my PDF's so something positive from the confusion !! I just spent about an hour composing a post with loads of info and links plus all the advantages and disadvantages I could find (like you I think it is neccessary to have both discussed) and as I submited it my connection dropped and the post was lost to the nether regions of cyber-space  :D:o !! I'll try and re-do it later (using a text editor this time)as right now my brain aches (sometimes it's good to get outside ones comfort zone !!) and it feels like beer O'clock  :D !!

P.S. if you've managed to get that "techno-translator" invention of yours working send it my way

Just had a look at the site Teletiger posted a link for in his previous post and recommend you all take a look !! Its the most comprehensive site I've yet seen on green manure and cover crops in the tropics !! A great example of members doing a bit of their own research to benefit the rest of us. I've researched this fairly thoroughly but google has never taken me here ?? Great stuff TT I might be able to scale down the aforementioned post I was gonna do and enjoy my beer :o !!

Edit : I've now read the site and won't even bother posting !! this link will go into the "useful links, resources and recommended reading" thread I'm working on

UHDP has indigoferra seeds.

Cheers

Good to see you in the forum Jeff

the ag shop in CR just before ban cheewit mai bakery looks to have recently expanded it's range (could just be the time of year ) and was selling two sizes of rice bean (the larger one was what I call red kidney bean) two sizes of black bean (I chose the smaller of both varieties) as well as soya bean, mung bean and a couple of others I couldn't identify (it was just chance that I noticed on passing and didn't have my list with me !!). they were all selling for 20 baht a kilo and 25 for the larger sized beans. Also had a good range of mushroom spore (thats for a later time) and EM and molasses.Good idea to save seed I hope to be able to do the same ! Haven't tracked down any indigoferra seed as yet considering bringing some back from the UK .

regards Jandtaa

I don't know about your area or about current availability, but in Chiang Mai I got free jack-bean seeds from the 'Land Development Office' (about 10k north of the SuperHwy on the Mae Rim (107) hwy, on the west (Doi Pui) side between the hospital and the (121) ring road).

At that time they had black beans, sesbania and others too. We didn't need a 'tabien baan', only my wife's ID, filled out a form with address and amount of rai. They calculated coverage rates and based the allotment on that; we pulled around back with the pickup and they loaded us up with the appropriate number of sacks of seed. I was only seeding about 4 rai, so I don't know what their upper limit is.

The land development office also does free soil analysis. The only problem is that it takes 45 days (sent to Lampang) and is a very basic NPK report with no interpretation or recommendations. I get better, more complete, 2 week soil analysis reports from Mae Jo University soil science department for 500 baht. And they have a soil science professor available to interpret and make recommendations for amendments if needed.

But you don't need a soil analysis to 'green manure'. don

I don't know why i never gave you a thanks on this posting but appreciate the doctoring help Dr. we will definitely be visiting the Land Development Office this year before any purchases. thanks for the info.

Thanks for this link. I've used the Rye (cerail grain) to cover before and it was extremely good. Nice to read what others say, it is one of my favorites and would be great fun to get into a half ton of seed. Know where to find any anyone (very reasonably priced normally)?????

I'm offf to try to dig up the botaical on my sun hemp seeds as that part of the thread helped answerr a few questions that I was pondering. i shall return. Forever in a Ford

Hi FF

yeah my old man uses rye grass in the UK on beds that have an invasive weed problem. Rye grass has alleopathic properties link to wikipedia as does indeed does rice. By the use of three plantings of rye and buckwheat (I think) he has had good success in removing the weeds. I agree it would be good to find a source out here. I'm also looking into using bamboo and eucalyptus leaves as a mulch/herbicide but need more info on whether they will also harm soil micro-organisms. Got in some green manure yesterday and there was more rain last night so hopefully I can finish the job today !!  

cheers for now

Jandtaa, re allelopathy (growth retardant properties of certain plants) For what it's worth, my plant pathology professor, after 50 years of directing graduate students on research projects at UC Berkeley, said that his observations showed that Eucalyptus didn't show true allelopathic properties like say black walnut (Juglans sp). Leaves used as mulch or composted did not retard growth of other plants when used outside of the context of the dense shade and heavy rooting of a Eucalyptus grove.

^Thanks Don that saves me some time I'll concentrate on the bamboo !

J

I suspect that with many plants that are thought to have allelopathic properties, the growth retarding aspect is due more to competition for light, water and nutrients than to chemical growth suppression. So don't count on it with bamboo or others unless your experience or review of solid research proves otherwise.

I've been trying to improve the soil in my little plot and have recently dug in a fair amount of semi composted water plants from the river. Also some matured cow manure. I just had to get some organic matter into the soil before the rain moves in with a vengeance.

I planted Tua Dam, black beans into these areas with the thought of digging this in later.

I'm just a little confused with the nitrogen fixing abilities of the bean. Now, from reading some of the excellent posts and links here, I understand that legumes will only fix nitrogen in the soil if a certain innoculant is present. I also understand that it is 3 or 4 weeks after germination that the plant will start to fix nitrogen.

What is not clear to me is the plants ability to absorb nitrogen from the air. If there is no innoculant present, can the plant still absorb nitrogen from the air or does it take all its needs from the soil? If all its nitrogen comes from the soil, then there would be no gain, in fact a loss as some nitrogen would be lost to the air when composting.

I hope that somebody can clear this up for me.

loong, My take on it has always been that legumes will take nitrogen from the air and fix it into nodes in their roots. This nitrogen will not be available to the soil until the plant dies and decomposes. (usually about 12 months...maybe faster in the tropics) The innoculant is needed for seed germination? All growing legumes will fix atmospheric nitrogen. Not 100% though.

"What did you do during the Thai civil war Grandad?"...."Why, Googled seed innoculants of course".

Regards.

Edit:..Quick look and I was wrong. The innoculant is for development of the nodules as you thought.

I've read the link Teletiger and it seems to be much the same as other sites. I have not been able to find any information as to whether Legumes can actually absorb nitrogen from the air if no innoculant present and a nitrogen deficiency in the soil.

Also can anybody tell me what Tua Dam, black beans are in English. If I google I only get references to black eyed beans or peas and these are not either.

Loong. Googled "non innoculated legumes". Lots came up.

It seems from this that legumes will take their nitrogen growth needs from the earth, innoculated or not.

Only innoculated plants will then go on to fix nodes.

Hi Teletiger,

I'm enjoying Songkran very much at the moment - I'm sat at the computer trying to get my new internet connection working on my new computer. It's very noisy outside in the village and I will be out later to get a soaking.

The beans I have are just what I bought in Tesco Lotus and stayed in the cupboard too long. As they are beans, i thought I would see if they will grow - and yes they do. I'm not growing to harvest, just for the fast growing greenery and, with luck, functioning root nodules as I've been incorporating partially composted organic material into the soil. I'm not sure if they are the same as a similar bean that I tried before, if they are, they will grow but not flower as the day length is not right for them.

The beans are just labelled Black bean, in Thai - ฤั่ดำ -Thua dam, not sure if they are the same as in your photo link or not. Many beans look the same.

I have looked at many websites, but they all seem to be fixated on nitrogen fixing in the soil. None actually seem to give the info whether or not legumes in a depleted soil will absorb nitrogen from the air if the innoculating enzymes are not present. I just want to know if there is not enough nitrogen in the soil, will legumes take their needs from the air, innoculated or not?

From this website

http://edis.ifas.ufl.edu/AG152

Symbiotic Nitrogen Fixation

Soon after a legume begins to grow, special N-fixing bacteria that reside in the soil invade the tiny root hairs and multiply in large numbers. The legume roots, in reaction to this infection, form tumor-like swellings called nodules on the root surface (see Figure 1). Bacteria inside the nodules absorb air from the soil and convert (fix) gaseous N into ammonia (NH3). The association between the legume host plant and the nodule bacteria is mutually beneficial (symbiotic). The plant furnishes the necessary energy that enables the bacteria to fix gaseous N from the atmosphere and pass it on to the plant for use in producing protein. This partnership is known as symbiotic N

fixation.

From reading other links, I had the impression that legumes absorb nitrogen through their leaves, a fair assumption if you are ignorant like me. But this states that the nodules take their nitrogen from air in the soil. That would mean that the soil will need to be loose, not compacted. It would seem to me that legumes are absolutely useless in a clay soil.

I have dug in a lot of partially composted organic material and now I wonder if the legumes will compete for the available nitrogen. The partially composted material wants nitrogen to fully compost and the legumes want nitrogen to grow and if inoculant is present will take more in the nodules. Mind you, now that everything has been well dug over and mixed the actual volume is twice the sum of its parts, so there must be plenty of air in there. I just hope that it's enough.

We will see.

Hi Loong 

hope these help with identification , the black bean I've sown is black seeded cow-pea, I think, just waiting for leaf, flower etc to confirm. Bit pushed for time at the minute with work commitments and sowing up veg and salad seeds (780 lettuce so far in various stages of growth) but if I get a couple of days off I'll try to post some more about nitrogen fixing. 

cheers for now and a slightly belated sawatdee pee mai

Thanks for the links.

Thua Dam is apparently

Bachapin bean, Black-eyed bean, Black eyed cowpea, Black eyed dolichos, Black eyed pea, Common cowpea, Cultivated African cowpea, Cowgram, Cow pea, Crowder bean, Southern pea, Crowder pea, Marble pea, Poona pea, Kafir bean.

So pretty confusing as these beans are black with a white eye.

I guess that I have planted black seeded cowpeas of some type - there seem so many. Still I suppose that it doesn't really matter as they are not intended as a crop.

Now it's a matter of waiting and hoping for some pink nodules on the roots.

I'm very happy,

nearly had an organicasm.

Beans have been in about 4 weeks now, I've planted them VERY close together and so have been cutting them back, so they are bushing more than running. Cuttings are going on the compost heap or as mulch. Today, I dug out a root and it had about 30 nodules about 5mm diameter and they are PINK.

Obviously the necessary bacteria was already present in the soil, so I now know that the black beans are doing their job.

When do you get back to Thailand Jandtaa, look forward to hearing some more from you.

Hi Loong 

Back in LOS around about the 2nd of September most likely depending on work, so just in time for the new growing season  :D !!

Glad your black beans are doing well and fixing nitrogen  :o:D (have you managed to confirm their identity through the foliage ?) love the term "organicasm" by the way !!

May your "nodules" remain full and healthily pink !! J

Jantdaa,

thanks to Teletiger and confirmed by your links and looking at the foliage, they are definitely Black Mung Beans. I couldn't be sure when Teletiger first posted the photo link, but now I am.

This thread may be interesting, it talks about sunn hemp for green manure, pls post any info you're able to find

http://www.thaivisa.com/forum/Improving-So...amp;pid=1721199

Thanks Smithson

I finally found a supplier of seed. Sun Hemp is called Paw Teung (pahh teu enhg) here and it goes for 40 baht a kilo if you are buying in bulk (I bought 200 kilos). They say 3-5 kilos per rai for green manure and Chownah has said he has had success in the 8 kilo a rai amount for broadcasting and discing. It germinates extremely fast, 4-5 hours soaking in warm water for me got some of the seeds to start showing its roots. Be careful not to soak too long if you want to "pre-emerge" your seeds as any longer than that or a delay in planting could be trouble. We just planted that and Sahnoh African (sesbania rostrata 40 baht a kilo and 3-5 kilo to a rai) last thursday the 25th and I will try to inform as the results come in. We are trying a few different methods to grow these two along with another bean that I don't have the name right now that is lima bean in size. The "Sanoh" is reputed to be a difficult grower with germination up to two weeks. Below is the contact of the company.

Thai Tanaht Praset in Chai Badan formely known as Lam Narai on Highway 21 half-way between Saraburi and Petchabun they are on the right side of the road about a kilo or two from the main clock tower on the highway.

Tua Plu seeds in bulk are impossible to locate still but I will continue to look. I'd love to at least get a few cans but can't find them.

Too too long on the computer and too sick to give more now but will update

Well I been away from this electric pencil for awhile and howdy to Fruity and Jandtaa and all. I need to update this. This year looks to be a good year for our first full year of organic (two years pesticide and poison free) and it appears that our methods are going to show a significant difference in yield, appearance and quality. It should all be cut tomorrow (looking at about 100 man days for 14 rai). i'm not going to go into all the results with our green manuring but as always when beginning "mixed" would be a good description for now, but more later. It appears that I have found the king of Paw Teung seeds and hope to purchase two tons from him this year (hopefully grow all our own thereafter) and am looking at around 25 baht per kilo. Last year found the last seeds in Thailand and had to pay 40. When he is able to perform on this I will post his contacts (the 700 kilos he had for us fell through once so we wait and see and hope he has no problems with his harvest of 2000 rai, purportedly). I would like to try Jandtaa's idea of mixing (pops in law did it with the Sanoh Africa (sesbania rostrata) and Paw Teung and it wasn't a good idea as they both have different growing cycles and didn't incorporate well) and anyway he might know why I told him not to mix those two anyway.

Anyone had any luck finding suppliers of large quantity of seeds for green manuring? I would love to get some rye (cereal). So good news possibly with the price of the Paw Teung alomost cut in half if it happens and I think it will. Will update with all our results later. Fruity it appears that we may have murdered a lot of tadpoles so there will be lots of vacanies in the Froggy Hilton. I'll get you over to see it hopefully in the beginning of Dec. Going after crab in California and tuna in Mexico for now.

HELP HELP HELP I still would like to find a local source of manure (some may remember that I hauled nearly 20 tons of finely broken down cow manure from Hua Hin (660 kilometers) from one of the King's Royal Projects to incorporate into our organic farm and would like to find some kind of source near Buri Ram (yeh good luck, also if they have any gold nuggets in it I will take them at no extra charge also). It appears someone has people going thru the villages searching sources of manure so that's good and bad news. Bad for me but good for the world as it appears that "organic" is making a comeback here. Choke Dee "...I know what I'll do.

A good read all. I too am dedicating several rai to a forest of various organically grown fruit trees in the Phetchabun mountains. This year I started with small 1 gallon trees and spaced them far apart so when mature the trees can have plenty of space so right now they are sort of like needles in a haystack of weeds. Most everything is doing well save the citrus leaves are being eaten seemingly by caterpillars. The weeds in the area left unchecked grow 3 meters tall and some are thorny. Currently just scythe the weeds periodically to keep them low and away from the trees. I wish to displace the weeds with a green mulch. Does that sound like the right approach? If so, what would be a good choice? If it is something close to optimal that has any edible parts (wing beans?) that would move it to the top of the list. And where should I look to find what I need for sale?

I don't know about your area or about current availability, but in Chiang Mai I got free jack-bean seeds from the 'Land Development Office' (about 10k north of the SuperHwy on the Mae Rim (107) hwy, on the west (Doi Pui) side between the hospital and the (121) ring road).

At that time they had black beans, sesbania and others too. We didn't need a 'tabien baan', only my wife's ID, filled out a form with address and amount of rai. They calculated coverage rates and based the allotment on that; we pulled around back with the pickup and they loaded us up with the appropriate number of sacks of seed. I was only seeding about 4 rai, so I don't know what their upper limit is.

The land development office also does free soil analysis. The only problem is that it takes 45 days (sent to Lampang) and is a very basic NPK report with no interpretation or recommendations. I get better, more complete, 2 week soil analysis reports from Mae Jo University soil science department for 500 baht. And they have a soil science professor available to interpret and make recommendations for amendments if needed.

But you don't need a soil analysis to 'green manure'. don

Just put in another crop of sun hemp but the big news was that the family was finally able to get free seeds from Buriram. Other provinces have been doing this for years but B stands for backwards and Buririam. Of course you couldn't go the 100 kilometers roundtrip they required you got a minimum of 7 people or they wouldn't give the seeds also had some crap about having to have land papers but that was forgotten or jive or whatever. Of course they wouldn't make it available until long after the optimum tiome to plant but what else is new. we are stockpiled for next year and hopefully will be able to get m0re. the soil has greatly imoroved with one year getting three crops in and also heard it is great for people klooking for pollinators for trees etc and have really notice plenty of flying bombadiers buzzing about doing their thing when 100's of thousaqnd of rai lie fallow all around.
