Abstract
Zbog niza čimbenika koji utječu na raspoloživost dušika u tlu, iznimno je teško pravilno izračunati i primijeniti optimalnu količinu dušika za usjeve. Cilj ovoga rada bio je izračunati količinu potrebnog dušika za prihranu ozime pšenice primjenom računalnog modela (kalkulatora) temeljenog na N-min metodi. Za izračun gnojidbene doze dušika i testiranje N-min kalkulatora, odabrane su tri parcele veličine 6x12 m na kojima je provedena kemijska analiza tla, te u jesen dodano 50% predviđenih potreba dušika prema unaprijed planiranoj gnojidbi(25 kg N ha-1, 55 kg N ha-1 i 85 kg N ha-1). Nakon toga provedena je N-min analiza u busanju i početku vlatanja na tri dubine (0-30, 30-60 i 60-90 cm) te pomoću N-min kalkulatora izračunate doze dušika potrebne za prvu i drugu prihranu. Utvrđeno je da je optimalna gnojidba za navedeni tip tla i ostvarivanje ciljanog prinosa od 7 t ha-1 sastavljena od niže doze dušika primijenjene u jesen pod osnovnu obradu (25 kg N ha-1) i izračuna prihrane N-min kalkulatorom na temelju analize tla (prva prihrana 101 kg N ha-1 i druga prihrana 60 kg N ha-1).
Abstract (english)
Due to a number of factors that affect the availability of nitrogen in the soil, it is extremely difficult to correctly calculate and apply the optimal amount of nitrogen for crops. The aim of this study was to calculate the amount of nitrogen required for winter wheat supplementation using a computer model (calculator) based on the N-min method. To calculate the nitrogen fertilization dose and test the N-min calculator, three plots of 6x12 m were selected, on which was performed a chemical analysis of the soil, and 50% of the predicted nitrogen needs were added in the fall, according to the pre-planned fertilization (25 kg N ha-1, 55 kg N ha-1 i 85 kg N ha-1). After that, N-min analysis was performed in drilling and beginning of drilling at three depths (0-30, 30-60 and 60-90 cm) and using the N-min calculator to calculate the nitrogen doses required for the first and second top dressing. It was found that the optimal fertilization for the specified soil type and achieving the target yield of 7 t ha-1 consisted of a lower dose of nitrogen applied in the fall under basic tillage (25 kg N ha-1) and calculation of fertilization N-min calculator based on soil analysis (first top dressing 101 kg N ha-1 and second top dressing 60 kg N ha-1).
