Uptake of mineral nitrogen from subsoil by winter wheat

Popis výsledku v původním jazyce

The apparent uptake of mineral nitrogen (Nmin) from top- and subsoil layers during the growth of winter wheat (Triticum aestivum L.) was studied in Praha-Ruzyně on clay loam Chernozemic soil in years 1996-2003. Two (N0, N1) and three treatments, unfertilized (N0), fertilized with 100 kg (N1) and 200 kg nitrogen per hectare (N2) were observed in years 1996-2000 and 2001-2003, respectively. The apparent uptake of nitrogen from soil layers was calculated from the changes of Nmin content between sampling terms. A most of available mineral N in the soil down to 90 cm was almost fully depleted between tillering and anthesis in treatment N0. The uptake from subsoil layers was delayed and it continued during the period of grain filling in fertilized treatments. Nitrogen fertilization reduced utilization of N from subsoil. The apparent uptake of N from the zone 50-120 cm ranged from 21 to 62 kg N/ha in N0 and from 15 to 60 kg N/ha in N1 in years 1996-2000. In years 2001-2003 the corresponding v
