Farming methods held as their own agricultural subject: how the land, water, crops and animals are actually worked, from soil and water conservation and crop rotation through integrated pest management, controlled-environment growing, alternative small-organism cultivation, traditional and mobile farming systems, and precision, genetic and holistic approaches. The tree under this category is a functional classification cross-checked against FAO conservation-agriculture and sustainable crop production intensification practice classes, controlled-environment agriculture and traditional farming-system typologies. Does not belong here: the tool or machine used to carry out a practice, which is Implement own subject, or the idea a practice is built on, which is Concept own subject; Practice holds the method itself.
