Development of wheat plants on soil reclaimed by mineral waste [articol]

Abstract

This study presents the influence of soil amendment with two mineral waste on the wheat plants development. Both types of tested mineral waste have resulted from the magnesium products industry, namely as waste-product and as deposits on the industrial equipment. The composition of these waste shows significant contents of precipitated magnesium and calcium carbonates as well as low contents of iron, copper, manganese and zinc. The difference between the two tested mineral waste lies in the double magnesium content, established for the crusts composition. An acid low fertile soil was treated with four different doses of each waste, in absence or in presence of nitrogen addition. The waste influence on the development of wheat was established by analysing some physiological characteristics of green wheat plants, on one hand as well as their essential and trace elements content, on the other hand.
