Abstract:

Pseudogley is a soil type that is under natural conditions characterized by unfavorable properties, the most pronounced being insufficient amounts of basic plant nutrients. Using different amelioration measures, numerous researchers have tried to overcome the problems resulting from soil acidity (increased aluminum and manganese contents, deficiency of alkaline cations in the adsorption complex and reduced available phosphorus content). Calcification was the most common measure almost always producing the best results of all the measures.

Effect of potassium fertilization on its available and fixed content in vineyard soil

Faculty of Agriculture, Belgrade-Zemun (1,2)

Abstract:

The experiment was conducted on brown forest soil in the vineyard with Sauvignon blanc variety on Kober 5BB rootstock. During a thre- year experiment (1994-1996), potassium fertilizer was added in a dose of 0 kg K2O/ha, 50 kg K2O/ha, 100 kg K2O/ha, 150 K2O/ha respectively.
