Effect of calcification on the content of elements N, P, K, Ca, Mg, Al, Mn, Mo, Cu and Zn in the analysed soil of pseudogley type

Abstract

Pseudogleya, s a type of soil, takes up some 500. 000 ha according to some pedological investigations (Zivkovic, 1970 and Tanasijevic et al., 1966). These are soils of acid reaction, relatively small content of humus and scarce availability with phosphorous and calcium. All these seem to be limiting factors of a successful agricultural production. The experiment was set up in order to test the content of N, P, K, Ca, Mg, Mo, Zn and Cu in the pseudogley type of soil. Wheat variety Srbijanka was sown. The readings of the elements before setting up of the experiment and those after the end of vegetation suggest a considerable impact of calcification on the differing increase in the content of all the elements except Al. Differing levels of calcification significantly affected changes in pH all through vegetation.
