PLANT NUTRITION AND NITROGEN FERTILIZATION AT DIFFERENT SYSTEMS OF SOIL TREATMENT

Popis výsledku v původním jazyce

The efficiency of mineral nitrogen fertilizers at different tillage operations were tested in the field trials conducted in Prague-Ruzyne location (altitude 340 m; annual precipitation 472 mm; annual average temp. 7,9°C; orthic Luvisol) during 2004-2007.The obtained results indicate the term and amount of rainfall following the fertilizer application had the deciding effect on utilization of nitrogen coming from fertilizers, especially if applied at the start of spring vegetation of winter wheat. In the trials using labelled 15N fertilizers the highest efficiency of nitrogen uptake by wheat plants was measured for nitrate form of nitrogen if used ammonium nitrate NH415NO3 at CT or RT (mean of three years: 66% at CT and 59% at RT). It was followed by urea with urease inhibitor (43%, 44% under CT, RT resp.) and urea alone (41%, 38% at CT, RT resp.). Ammonium nitrogen from 15NH4NO3 was taken by plants the least (15%, 21% at CT, RT resp.). Urease inhibitor NBPT showed the most positive if
