Effect of phosphorus microfertilizers on chemichal properties of maize

Cilj ovog istraživanja bio je utvrditi razliku kemijskom svojstvu kukuruza između kontrolnog usjeva i usjeva gdje su aplicirana mikrogranulirana fosforna gnojiva Elixir Zorka tvornice gnojiva pri čemu je primjenjeno 5 tretmana: kontrola, Nutriboost PR, Nutriboost PR-45, Nutriboost HK, Nutriboost HK-45. Pri tome je kod tretmana Nutriboost PK-45 došlo do porasta organske tvari u tlu nakon provedenog pokusa, dok je primjenom tretmana Nutriboost HK i Nutriboost HK-45 došlo i do blagog povećanja koncentracije fosfora i kalija u kukuruzu u odnosu na kontrolu. Limitirajući faktor u uzgoju u kontroliranim uvjetima bila je količina svjetla, a kako bismo dobili što preciznije i realnije rezultate, poljske pokuse bilo bi dobro postaviti na tlu istih kemijskih osobina kao tlo koje je korišteno za uzgoj u posudama.The aim of this study was to determine the difference in the chemical properties of maize between control crops and crops where microgranulated phosphorus fertilizers Elixir Zorka fertilizer factory were applied using 5 treatments: control, Nutriboost PR, Nutriboost PR-45, Nutriboost HK, Nutriboost. The Nutriboost PK-45 treatment showed an increase in organic matter in soil after trial, while the Nutriboost HK and Nutriboost HK-45 treatments showed a slight increase in phosphorus and potassium concentrations in maize plant compared to the control. The limiting factor in cultivation under controlled conditions was the amount of light, and in order to obtain as accurate and realistic results as possible, field experiments would be well placed on soil with the same chemical properties as the soil used for pot cultivation
