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 the experiment, four amendments were applied in an experimental set of plots: tobacco waste compost (TWC), poultry manure (PM), bio-humus (BH), and chemical fertilizer (NPK). Soils were treated with TWC at the rate 50 t ha-1, PM at 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 were increased soil pH, OM, CEC, EC and corn yield when compared with the control soil and these parameters have been changed 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 priority for improving properties of a Typic Xerofluvent soil and crop yield.
Highlights
Nowadays, the use of organic treatments for soil nutrient improvement is getting important for sustainable productivity and soil nutrient management
Several researchers reported that addition of organic manure and compost to the soils significantly increased electrical conductivity (Candemir & Gulser 2011; Morugan-Coronado et al 2011; Cercioglu et al 2012)
Some studies showed that organic matter (OM) increases were temporary, since the organic material is rapidly mineralized by soil microorganisms (Mechri et al 2007; Di Serio et al 2008)
Summary
The use of organic treatments for soil nutrient improvement is getting important for sustainable productivity and soil nutrient management. Tobacco plant residues from the primary production and cigarette manufacture are classified as an agro-industrial waste This waste contains high amounts of organic matter and nicotine and is known to be a toxic and hazardous compound if the nicotine content exceeds 500 mg kg-1 dry weight (Wang et al 2004; PiotrowskaCyplik et al 2009). In this investigation, tobacco waste compost (TWC), poultry manure (PM), bio-humus (BH), and chemical fertilizer (NPK) at different ratios was applied to soil and the influences of these conditioners on selected chemical properties of a sandy loam soil and corn yield were compared
