I see videos of successful bund dig operations; digging half-craters to catch water apparently keeps the water from flashing off. Tilling turns topsoil to dirt due to solar radiation. No-till farming methods like residue mulching prevent soil depletion and retain water in topsoil; in order to create healthy soil as an output. Hugelkultur is basically residue mulching and rainwater catchment. Removing all of the trees reduces the level of water in the air and soil. What sorts of agricultural machines can service bunds, raised beds, and hugelkultur mounds instead of rows?
