So far, wherever serious attempts have been made to make it work, all problems (for example regarding weeds, pests and diseases, or the provision of forage for animals which would usually compete with the soil for residues) can be solved in relatively short order. Where conservation agriculture has been adopted on a massive scale, with good rotations and for a long time, it can be proven that weed and disease problems, and thus the use of agrochemicals, tend to decline and eventually reach levels below that of conventional agriculture.

Nevertheless, conservation agriculture has so far provided sustainable answers wherever it is applied, whereas conv
