Changing properties of the mesotrophic peat soil in grain-row crop rotation under the influence of fertilizers and lime

Under consideration is an estimation of changes in the properties of drained mesotrophic peat soils affected by NPK, manure, copper and lime in a long-term field experiment with oats and potatoes. Liming of acidic mesotrophic peat soils in connection with NPK increases gross reserves of Ca in the soil, reduces the hydrolytic acidity, the content of exchange forms of Al 3+ and H +, mobile forms of P and K (the latter effects considerably the soil fertility at lime doses of more than 0.50 Hг).
