Effects of organic amendments on the salt-affected soil

An experiment was performed to examine the physical and chemical effects on high salt-affected soil following the incorporation with four kinds of organic wastes (poultry manure, commercially available fertilizer, reed straw, fresh reed straw with green leaves). Organic wastes were applied at rates of 15g/kg. The effect on the soils physical and chemical properties, soil soluble organic carbon were ascertained after one month. Available nitrogen increased more markedly in the PM-amended soils (537%) and sodium absorption ratio (SAR) decreased more significantly in the RS-amended soil (27%) compared to the control soil. Water-soluble organic carbon and soil respiratory intensity were the highest in all treatments. The work demonstrated that organic wastes can ameliorate soil structure, improve soil physical and chemical properties and biological activity in high salt content soil.
