Charles of Kaishe demonstrated his model farming techniques to us.  Here he is in front of his compost heap - taking green and dried grass mixing with water and animal manure, turning regularly until he gets a nice mulch.  With this infertile land, they have discovered if they dig 6 inch holes about 2 feet apart in their field, filling each with this compost it will lead to better crops.  It takes more work for the first two years but once established, re-using the same holes over time, work and yield greatly improves and is much better for the environment than what they presently do which is to burn the fields about this time of year right before seeding time which needs to occur before mid November when rainy season begins.
