Abstract
Na OPG-u Kopić Ivan analizirano je tlo na kojemu je utvrđena niska pH vrijednost (5,78) te je tlo ocijenjeno srednje kiselim. Kako bi se postigla ciljana pH vrijednost 7,00 2017. godine izvršena je kalcizacija karbokalkom u količini 8.500 kg/ha te nakon toga dvije osnovne obrade tla (oranje) tokom 2017. i 2018. godine. Ponovna analiza oraničnog sloja tla 2019. godine pokazala je kako je tlo i dalje srednje kiselo i kako nije postignut očekivani učinak. Dodatnom analizom na različitim dubinama tla utvrđeno je kako je najveća pH vrijednost bila na dubini 20-30 cm (7,3) dok je tlo u ostalim slojevima i dalje prekiselo pa je zaključeno kako sredstvo za kalcizaciju nije ravnomjerno rapodijeljeno po cijelom oraničnom sloju. Analiziran je kemijski sastav karbokalka i utvrđena neutralizacijska vrijednost (43,46 %). Utvrđena je koncentracija Ca u karbokalku 332,48 g/kg, a Mg 11,85 g/kg. Na temelju neutralizacijske vrijednosti karbokalka utvrđeno je kako je bilo potrebno primijeniti 10,96 t/ha za postizanje ciljne pH vrijednosti 7,00 po cijelom profilu oraničnog sloja tla. Raspodjelu sredstva za kalcizaciju trebalo je provesti u dva prohoda kako bi se sredstvo ravnomjernije izmiješalo s tlom uzveću učinkovitost.
Abstract (english)
At family farm Ivan Kopić, soil was analyzed and a low pH value (5.78) was determined and the soil was evaluated as acidic. In order to reach the target pH value 7.00 in 2017, limingwith 8500 kg/ha of carbocalk was performed followed afterwards by two basic tillage operations in 2017 and 2018. A re-analysis of the soil (0-30cm) in 2019 showed that the soil was still medium acidic and that the expected effect had not been achieved. Additional analysis at different soil depths revealed that the highest pH value was at a depth of 20-30 cm (7.3), while the soil in the other layers was still slightly acidic, and it was concluded that the limingmedium did not mix well enough throughout the plow. The composition of carbocalkand its neutralization value (43.46%) were analyzed. The Ca concentration in the carbocalk was 332.48 g/kg, while the Mg was 11.85 g/kg. Based on the neutralization value of the carbocalk, it was determined that at first 10.96 t/ha should be applied to reach the target pH 7,00. It was recommended to distribute limingmedium in two applications in order to better mix the medium with the soil and to achieve better efficiency of neutralization.
