The Impact of Soil Conditioners on Some Chemical Properties of Soil and Grain Yield of Corn (Zea Mays L.)

Abstract

The goal of this study was to explore the effects of various soil conditioners on selected properties (pH; organic matter,OM; electrical conductivity, EC; cation exchange capacity, CEC) of a Xerofluvent soil and corn yield. During theexperiment, four amendments were applied in an experimental set of plots: tobacco waste compost (TWC), poultrymanure (PM), bio-humus (BH), and chemical fertilizer (NPK). Soils were treated with TWC at the rate 50 t ha-1, PMat the rate 4 t ha-1, BH at the rate 10 t ha-1 and NPK at the rate 300 kg ha-1, respectively. All organic conditioners wereincreased soil pH, OM, CEC, EC and corn yield when compared with the control soil and these parameters have beenchanged from 5.7% to 333%. The most effective soil conditioners were determined as tobacco waste compost, biohumus,and poultry manure. The findings of current study suggest that 50 t ha-1 TWC should be added to soil as a priorityfor improving properties of a Typic Xerofluvent soil and crop yield.
