It is me the soil. I suggest farmers for composting first and then apply to the main field. It will save me and our earth from the danger of methane. I have worked through this body on the development of a soil testing kit and soil health card (Excel format auto recommendations). And folmulated a DEXCELMAP. One can prepare a soil fertility map by Dexcel map, using an excel sheet, word and powerpoint . To prepare a map there is no need of having softwares, like ARCGIS / ERDAS or others.
