Abstract:

Soil fertility is influenced by different forms of land use. In a field trial (Western Lithuania, Vezaiciai branch of the Lithuanian Agriculture Institute) two manure rates (40 t ha-1 and 60 t ha-1) were introduced in acid and limed soil. The mineral fertilization in both acid and limed soil was the same: N60P60K60 for cereals, N120P90K150 for forage beet, N40P60K60 for barley with undercrop, P60K90 for perennial grasses in the 1st usage year, N60P60K90 for perennial grasses in the 2nd usage year. It was revealed that the long-term manuring and liming combination had a positive effect on moraine loam Dystric Albeluvisol fertility. Application of manure in acid and limed soil increases the nutrient stocks in the rooting zone of crops, increases pH value, amount of organic carbon and thus improves the topsoil structure. Long term manuring at rate 60 tha-1 resulted in the highest amount of mobile phosphorus (329 mg kg-1) in limed topsoil. The amount of mobile aluminium was reduced from 112.9 to 16.6 mg kg-1 if manure at a rate of 60 t ha-1 was applied. The combination of liming and fertilization ensure soil chemical indicators at the optimal level for more plant growth.
