Abstract
U okviru diplomskog rada cilj je bio prikazati razliku između gnojidbe pojedinačnim i kompleksnim mineralnim gnojivima kroz nekoliko aspekata: ušteda aktivne tvari i ekonomska isplativost gnojidbe pojedinačnim gnojivima, pogodnost pojedinačnih gnojiva za preciznu gnojidbenu bilancu u proizvodnim sustavima u RH, značaj precizne aplikacije gnojiva zbog heterogenosti proizvodnih površina na malim i velikim proizvodnim sustavima, pozitivan utjecaj optimalne gnojidbe na prinos, svojstva tla i okoliš. Komparacija primjene pojedinačnih i kompleksnih gnojiva pri gnojidbi kukuruza, ukazuje na povoljniju cijenu pojedinačnih gnojiva. Cijena kod konvencionalne gnojidbe sa pojedinačnim gnojivima iznosi 1.445,50 kn/ha prosječno, dok kod kompleksnih gnojiva iznosi 5.655 kn/ha prosječno. Gnojidba kukuruza kod konvencionalne gnojidbe jeftinija je gnojidbom pojedinačnih gnojiva za više od 4000 kn/ha u odnosu na kompleksna gnojiva. Ovo je prilično radikalan rezultat jer se radi o tlu siromašno opskrbljenom kalijem pa su rezultati ekstremni, a s druge strane ukazuju na neophodnost upotrebe pojedinačnim gnojivima u takvim situacijama.Udio gnojidbe u ukupnim varijabilnim troškovima kod konvencionalne gnojidbe za kompleksna gnojiva iznosi 52 %, a za pojedinačna gnojiva iznosi 15 %. Nadalje, ostvareni prinosi prema postavljenoj shemi pokusa bili su: 7,9 tha-1 na kontroli (bez gnojidbe), te 9,5 tha-1 (konvencionalna gnojdba kompleksnim gnojivima), odnosno 10,05 tha-1 (precizna gnojidba pojedinačnim gnojivima).

Tthesis objective was to show the difference between individual and fertilization complex mineral fertilizers through several aspects: the saving of the active substance and the economic viability of individual fertilization fertilizers, fertilizer for the convenience of single precision fertilizer balance in production systems in Croatia, the importance of precise application of fertilizer because of the heterogeneity of production areas in small and large production systems, positive impact on the optimal fertilization yield, soil properties and enviroment. Comparisssion of individual and complex fertilizers application in the fertilization of corn, indicating the favorable price of individual fertilizers. Price for conventional fertilization with individual fertilizers is 1,445.50 € / ha on average, while in complex fertilizers amounted to 5,655 € / ha on average. Fertilization of corn in conventional production is cheaper by fertilization with individual fertilizer for more than £ 4000 / ha compared to the complex fertilizer. This is quite a radical result because it is a poor soil stocked potassium and results extreme, on the other hand call for the use of the individual fertilizers such cases. Fertilization ratio in total variable costs in conventional production for complex fertilizers is 52% and for individual fertilizer is 15%. Furthermore, the yields according to a set scheme of the experiment were 7.9 tha-1 in the control (without fertilization), and 9.5 tha-1 (conventional gnojdba complex fertilizers) or 10.05 tha-1 (single precision fertilization fertilizers).
