Evaluation of soil convenience for agricultural production in the area of Žepče

Cilj ovog istraživanja bio je utvrditi pogodnost tala za ratarsku proizvodnju na području općine Žepče, potrebne mjere popravka i gnojidbe te utjecaj kemijskih svojstava tla na raspoloživost teških metala u tlu. Analizirano je 12 uzoraka sa 2 različita lokaliteta. 6 uzoraka uzeto je sa brežuljkasto brdovitog krajolika, a drugih 6 uzoraka uzeto je iz doline rijeke Bosne. Provedena su terenska i laboratorijska istraživanja sa osnovnim kemijskim te pedofizikalnim analizama tla. Utvrđeno je da u istraživanim uzorcima na području općine Žepče imamo nizak sadržaj organske tvari te da je prosječna pH reakcija tla neutralna. Također je utvrđeno da su sva tla bezkarbonatna ili slabo karbonatna, a razina fosfora i kalija je niska do umjerena. Analizom pedofizikalnih svojstava tla utvrđeno je da tlo čine ilovača te praškasta ilovača. Zabilježene su značajno povišene koncetracije nikla i kroma, dok su ostali teški metali unutar dopuštenih granicaThe aim of this study was to determine soil suitability for field production in the area of Žepče. Also, necessary repairs and fertilization measures and furthermore, the influence of the chemical properties of the soil on the availability of heavy metals. 12 samples were analyzed, taken on 2 different locations. Six samples were taken from a hilly landscape, and the other 6 samples were taken from the valley of the Bosna River. Field and laboratory studies were conducted with basic chemical and pedophysical soil analyzes. It was determined in taken samples that there is a low content of organic matter and that the average pH of soil reaction is neutral. It has also been found that all soil is non-carbonated or poorly carbonated, and phosphorus and potassium levels are low to moderate. By analyzing the pedophysical properties of the soil it has been established that the soil is made of loam and powdery loam. Significantly higher concentrations of nickel and chromium were observed, while other heavy metals were within the limits allowed
