Abstract
Kukuruz zbog vrlo širokog uzgojnog areala može uspijevati u različitim klimatskim područjima i na tlima različite plodnosti. U RH kukuruzom je zasijano oko 250 000 ha poljoprivrednih površina, od čega 1/5 u Osječko-baranjskoj županiji. S obzirom na važnost kukuruza potrebno je posebnu pažnju posvetiti povećanju proizvodnje kroz postizanje viših prinosa i očuvanje okoliša. Korištenjem naprednih alata kao što su geostatistička analiza i ALRxp gnojidbeni kalkulator moguće je napraviti preciznu, izbalansiranu gnojidbu prema zahtjevima biljaka utemeljenu na analizi tla. Iz tog razloga je cilj u izradi ovog rada bio procijeniti količinu hraniva potrebnog za uzgoj kukuruza na području Osječko-baranjske županije primjenom napredne geostatističke metode kriginga. Istraživanjem je obuhvaćeno 5184 uzoraka tla s površina na kojima je bila planirana sjetva kukuruza. Na temelju rezultata kemijskih analiza u županiji prevladavaju kisela tla uz prosječni pH-KCl 5,43 i slabo humozna s 2,05 % humus. Prosječna opskrbljenost pristupačnim fosforom i kalijem je dobra uz vrlo visoku varijabilnost što upućuje na različite načine gospodarenja. Prosječne vrijednosti potrebnih količina glavnih elemenata ishrane su: 170,23 N kg ha-1, 93,28 P2O5 kg ha-1 i 96,61 K2O kg ha-1. Potreba glavnih elemenata ishrane za kukuruz obavljena je geostatističkom analizom EBK (Empirical Bayesian Kriging) u 7 klasa za cijelo područje Osječko-baranjske županije. Najveći broj uzoraka za N-potrebu nalazi se u klasi 6 (150 - 175 kg N ha-1), za fosfor u klasi 5 (100 – 120 kg P2O5 ha-1), a za kalij u klasi 3 (90 - 120 kg K2O ha-1).
Abstract (english)
Due to its very wide cultivation area, maize can thrive in different climatic areas and on soils of different fertility. In the Republic of Croatia, about 250,000 ha of agricultural land have been sown with corn, of which 1/5 is in Osijek-Baranja County. Given the importance of maize, special attention needs to be paid to increasing production by achieving higher yields and preserving the environment. Using advanced tools such as geostatistical analysis and ALRxp fertilization calculator it is possible to make a precise, balanced fertilization according to plant requirements based on soil analysis. For this reason, the purpose of this paper was to estimate the amount of nutrients needed for maize cultivation in the Osijek-Baranja County using an advanced geostatistical method of kriging. The research included 5184 soil samples from the areas where corn sowing was planned. Based on the results of chemical analyzes in the county, acidic soils with an average pH-KCl of 5.43 and weakly humus with 2.05% humus. The average supply of affordable phosphorus and potassium is good with very high variability, which indicates different ways of management. The average values of the required amounts of the main nutrients are: 170.23 N kg ha-1, 93.28 P2O5 kg ha-1 and 96.61 K2O kg ha-1. The need for the main elements of nutrition for corn was performed by geostatistical analysis of EBK (Empirical Bayesian Kriging) in 7 classes for the entire area of Osijek-baranja county. The largest number of samples for N need is in class 6 (150 - 175 kg N ha-1), for phosphorus in class 5 (100 - 120 kg P2O5 ha-1), and for potassium in class 3 (90 - 120 kg K2O ha-1).
