Effect of N fertilization on changes of nutrient concentrations in soils

Popis výsledku v původním jazyce

Nitrogen (N), phosphorus (P) and potassium (K) fertilization is decisive for correct plant nutrition and adequate crop yields. This research was aimed at evaluating the effect of different levels of nitrogen fertilization on the availability of nutrients in soils from a long-term field experiment established in 1984 at two experimental sites with different pedo-climatic conditions in the Czech Republic.The field experiment consists of mineral, farmyard manure (FYM) or straw, and four different applied doses of mineral N given to each of the basic fertilization systems (0-40-80-120-160 kg N ha-1). P and K is given to each treatment (with the exception of the unfertilized control) in annual doses of 35 kg P ha-1 and 83 kg K ha-1. The level of N fertilization increased the average yields during the experiment. The mineralization processes induced by the N supply also led to a decrease of soil pH of about 0.3-0.45. Both factors affected the nutrient availability in the soils. Generally, the nutrient contents (mainly P, K, Ca) decreased with increasing N dose, however differences depending on the soil type at each experimental site were noted. The content of S increased proportionally with N dosage at both experimental sites. Considering all obtained results, the N showed to be the important factor affecting the nutrient contents in agricultural soils. Optimized soil fertilization should lead to the harmonised plant nutrition which is important and necessary for adequate crop yields and plant health.
