The paper presents the results of research into the activity of alkaline and acid phosphatase, the content of available phosphorus, heavy metals and total organic carbon, against in soil with mineral fertilization only. The first experimental factor was phosphorus, potassium, magnesium, calcium and sulphur fertilization in six fertilizer combinations: 1: (PKMgCaS), 2: (KMgCaS), 3: (PMgCaS), 4: (PKCaS),...
The aim of the present paper was to determine changes in the content of available phosphorus and the activity of alkaline and acid phosphatase as a result of nitrogen fertilisation at the following rates: 0, 30, 60, 90, 120, 150 kgN ha–1and mineral fertilisation (P, K, Mg, Ca and S) in soil under spring barley. The soil was sampled in June and October 2008 from a field experiment set up in the area...
