The effect of irrigation by sugar factory effluent (spentwash) and the well water from adjoining area has been studied in Wardha district, Maharashtra. The effluent had high TDS (422-608 mgL(-1)), COD (1152-17680 mgL(-1)) and BOD(380-650 mgL(-1)) than well water (TDS 240 mgL(-1), COD 3.8 mgL(-1) and BOD 1.2 mgL(-1)). There found some nutrients, viz. N, P, K, Zn, Cu, Fe, Mn in surface layer of soil in different seasons. Heavy metals (Cd, Co, Cr, Ni, Pb) were found to be within the permissible limits.
在马哈拉施特拉邦瓦尔达地区，对糖厂废水（废液）灌溉以及毗邻地区井水灌溉的效果进行了研究。该废水的总溶解固体（TDS）（422 - 608毫克/升）、化学需氧量（COD）（1152 - 17680毫克/升）和生化需氧量（BOD）（380 - 650毫克/升）均高于井水（TDS 240毫克/升、COD 3.8毫克/升和BOD 1.2毫克/升）。在不同季节的土壤表层发现了一些养分，即氮、磷、钾、锌、铜、铁、锰。发现重金属（镉、钴、铬、镍、铅）在允许限值范围内。
