Effect of Different Mineral and Organic Fertilization on Uptake and Balance of Nutrients as well as on Contents of Dl-soluble Phosphorus and Potassium in a Long-term Trail

Abstract

On the basis of results from stationary long-term trails the accumulating effects of different mineral-organic fertilization on the uptake and the balance of nutrients as well as DL-soluble P and K contents in soil was examined. The long-term varied fertilization affected the uptake and the balance of nutrients considerably. With farmyard-manure supplied doses of P and K caused a significant higher increase of the plant-available soil contents in comparison to the straw-fertilization and also to the pure mineral PK-supply. The organic fertilization obviously favours by increased humus contents and a thereby promoted biological activity the solubility behavior of phosphorus and potassium.
