I have heard that in Viet Nam some farmers use blue-green algae to add nitrogen to the soil at this stage, but I can't confirm if that is true. The time that the fields are fallow in the farms I am thinking of in Thailand is during the dry season. It doesn't rain for months and it is really quite hot, especially in the sun as these fields are. It is quite a different set of circumstances from when I plant hairy vetch in my garden for the winter in New York! Anyway, thanks for the tip on cress. I will look into that. Meanwhile does the new information about the conditions bring any ideas to anyone's mind? Thanks Alfalfa? That is a legume crop so would add nitrogen back to the soil, and is very valuable as a livestock feed. They used to grow it when I lived in California in the Mojave desert. Might need some irrigation, but should not be too bad. I'm interested in hearing ideas from others. ;-) K. Alfalfa is not a very likely to be a candidate. It requires a LOT of water and was likely grown in the Mojave in winter with highly subsidized irrigation water. If the Thai's had "free" water, they could grow a number of things, non least of which would be a second crop of wet rice. |
