dcterms:description
Between 2001 and 2012, application of organic and mineral fertilisers did not significantly influence the N and Cox topsoil content. The N content increased in the order: Control < CAT, NPK < CAT+STR < FYM < NPK+FYM; Cox showed a similar pattern. As the aboveground parts of the plants are not returned back to the soil in our experiment (except in one treatment), the higher N and Cox contents in well-fertilised treatments are caused due to a richer root system, the only source of organic material. Phosphorus and potassium concentrations did not differ significantly between organic treatments; the content was equal, but was significantly higher in NPK and NPK+FYM treatments. Calcium and magnesium concentrations behaved oppositely. While regular application of high doses of mineral nutrients can provide high yields and leave a relatively good pool of nutrients in the soil, organic fertilisers release more nutrients (N, P, K, Ca, Mg and others) in smaller doses and in a longer period. If the application of mineral fertilisers is not amended with regular application of Ca, the soil pool of those nutrients can decrease significantly and negatively influence the pH value. Thus, the combined application of mineral NPK and FYM provides a wide range of nutrients, which are released in both, short and long periods, and reduce the negative effect of NPK on topsoil pH.
