Abstract
The prevailing farming system in Moldova has brought about a loss of humus, degradation of soil structure and compaction of the plough layer of chernozem soils. The most effective remedy is steppe vegetation. Fifteen years under grass fallow restored 80 % of the humus and 95 % of structural quality. Five years under lucerne had little effect; but growing a legume-and-grass mixture for 5 years restored tilth, the degraded plough layer was enriched with organic matter and plant residues (by 0.45 % or 0.1 % annually), soil structure improved and a sod began to form. Large-scale implementation of this method requires restoration of the livestock sector and allocation of 15–20 % of the land to perennial grasses.
