Agrolandscapes make up the largest part of the world's man-made landscapes. Their soils are subjected to annual mechanical cultivation; fertilizers and toxic chemicals are applied. All this leads to specific contamination of soils with a number of chemical elements. All over the world, certain agro-landscapes are periodically withdrawn from agricultural turnover. In this regard, it is important to answer the question: whether geochemical "soil self-remediation" is possible in this case or not. If geochemical self-recovery is possible, it is desirable to know how long it can happen. We have developed a methodology of works on the basis of monitoring studies. On its basis this problem was considered for tea plantations of the Western Caucasus.
