  1. Thought some may be interested in the mixed green cover we sowed on 30 June. I waited until the end of June as I wanted the cover crop to be high enough but not over mature, to roll down in the last week of August when we will sow a cash crop in the field. I think the timing was about right, in 2 weeks the cover will probably double in volume over where it is now. We will roll it down and then wait a week and sow our cash crop into the residue. I am debating whether to use a herbicide application on the cover crop either pre or post rolling. There is a definite weed presence which we will have to control before sowing the next crop. We sowed around 25 species in the cover mix. Some as one would expect do not show at all, others are real stars. The species which are predominating and doing well and which I would build a future mix around for wet season sowing are Sunflowers, Sorghum, Sesame, Kenaf, and some of the beans including Cowpeas and Canavallia. So next time we will look to use these 6 species as the basis of around 80% of the cover mix. We also added Alyce, which is much slower growing but is covering the ground under the taller covers. This is one reason I don't want to spray as the Alyce forms a nice low spreading plant which when we combine our main crop in December we can take off the Alyce seed as well and can sell it as a by-product. Perhaps my best option to avoid either turning the soil, or spraying is to graze the cover crop.We don't have any stock but there are plenty in the area who do have, so that is a possibility if it can be organised. We sowed another field a couple of weeks later with a mix with more emphasis on grass covers including Millet, Maize and a couple of different Sorghums. This is also looking good for a roll down mid September

    2 new speed cams!

    I drive this route to and from Phang Nga nearly every day. Coming inbound to Phuket off Sarasin Bridge the speed is 90 for where the camera is placed. It is 80 on the bridge, then goes to 90, and after the camera coming up to the checkpoint goes down to 60. Out bound from Phuket the speed limit for where the new cameras are near the Shell garage is 60. However I think that they are just picking up all vehicle details coming and going with these cameras as a previous poster has said they flash even if you are well below the speed limit. Let us know if you get a ticket, but I have not, then again tickets usually take a couple of months to arrive, and the cameras were only installed as they reopened Phuket but must be getting close to 2 months now.
  3. Is anyone interested in this area? I had a look through the OP's for a few pages and did a search but did not bring anything up on the forum. As someone who has been around farming and especially organic production for many years, this seems to be an approach which has a lot of merit, and from the scientific evidence coming forwards it looks as if there may be an opportunity if this approach was widely adoption to mitigate some of the worst effects of increasing carbon dioxide levels whilst producing high quality food and other agricultural products in a profitable manner. There seems to be little work going on in Thailand either practically or academically at present, but I would love to stand corrected on this if anyone has any input. For those not familiar with the basic principles of regenerative agriculture they are little or no soil disturbance maximise plant diversity maintaining living plant cover at all times low artificial chemical pesticide and fertiliser inputs and integrate livestock if at all possible Farms following all these principles are being measured as increasing organic matter levels in the soil up to 0.5% a year. Hence the interest from climate change researchers. Drawing down carbon from the atmosphere and locking it into soils is a very cheap and effective way to reduce carbon dioxide levels. For those who wish to pursue this area further, there is already quite a lot of information available. Some is coming from academia in the form of scientific papers, others from practical farmers. Here is the list of some of the more accessible information starting with farmers and moving to the more academic research.

Being a microbiologist by training he has a very interesting take on things and produces the evidence to prove his points. We have built three of his style of compost heaps but the first will not mature for up to another 6 months. I am not quite sure on timing as his work in Arizona suggest 1 year as optimal, perhaps with the constant heat here in Thailand we can reduce this somewhat. Our first one is 6 months old. https://media.csuchico.edu/media/Soil+MicrobesA+Their+Powerful+Influence+in+Agroecosytems/0_ltz0ea1h https://holisticmanagement.org/wp-content/uploads/2015/05/Quivira_Johnson1.pdf https://www.youtube.com/watch?v=dmj611RfBgs https://www.youtube.com/watch?v=MuW42tFC4Ss https://www.youtube.com/watch?time_continue=164&v=18FVVYKU9gs&feature=emb_logo Thailand - and finally a Thai twist on things, this is the only work I could find being done here. https://www.asean-agrifood.org/farmers-in-central-thailand-turn-to-alternative-crops-to-sustain-soil-health-after-harvest/ I would love to hear from others interested in this area.
