Abstract
Na raspoloživost dušika u tlu utječe mnogo različitih čimbenika, a prihrana dušikom često se izvodi „napamet“ bez analize i detaljnog izračuna doza dušika. Takvim načinom možemo negativno utjecati na okoliš (prekomjerne doze) ili prinos (nedostatak dušika). Zbog toga cilj ovog završnog rada je utvrditi optimalnu dozu dušika za prihranu ozimog ječma koja će se temeljiti na analizi tla i izračunu doze naprednim gnojidbenim kalkulatorom. Za izračun doze dušika primijenjena je N-min metoda i N-min kalkulator. Prosječna vrijednost nitrata u analiziranim uzorcima tla iznosila je 3,34 mg/kg N-NO3- i 4,45 mg/kg N-NH4+. Izračunata doza dušika za prinos od 6,0 t/ha iznosila je 68 kg/ha N. Rezultati N-min metode pokazali su se vrlo korisnim i uvelike su pomogli odrediti količinu potrebnih hranjiva koja su biljci nedostajala.
Abstract (english)
The availability of nitrogen in the soil is influenced by many different factors, and nitrogen supplementation is often performed "by heart" without analysis and detailed calculation of nitrogen doses. In this way, we can negatively affect the environment (excessive doses) or yield (lack of nitrogen). Therefore, the goal of this work is to determine the optimal dose of nitrogen for winter barley, which will be based on soil analysis and calculation of the dose with an advanced fertilization calculator. The N-min method and the N-min calculator were used to calculate the nitrogen dose. The average nitrate value in the analyzed soil samples was 3.34 mg/kg N-NO3- and 4.45 mg/kg N-NH4+. The calculated dose of nitrogen for a yield of 6.0 t/ha was 68 kg/ha N. The results of the Nmin method proved to be very useful and greatly helped to determine the amount of necessary nutrients that the plant lacked.
