The paper presents data on the annual rate of humus accumulation after 10 and 20 years of a strict experimental routine carried out on sterile waste dumps (anthropic protosol) from Cápuş, cultivated with maize, oat and esparcet. Basic dressing applied was the following: V1 - unfertilized, V2- 40 t/ha manure, V3 - 15 t/ha poultry manure, V4 - 40 t/ha manure + N100 P60 K40 , V5 - 15 t/ha poultry manure + N100 P60 K40 , V6 - N100 P60 K0 , V7 - N100 P60 K40, V8 - N200 P120 K80 , V9 - N300 P180 K120. The results obtained revealed that the variant with 40 t/ha manure + N100 P6O K40 (V4) after 10 years accumulated 1.724% humus and after 20 years 4.100% humus. It means that the annual average rate was 0.115% and 0.176%, respectively, at a depth of 0-20 cm. The next variant is the variant with 15 t/ha poultry manure + N100 P60 K40 (V5) where 1.207% of humus was accumulated after 10 years and 3.760% of humus after 20 years; the annual average rate 0.055% and 0.155%, respectively.
