Abstract: The uncontrolled disposal of yeast factory wastes is not properly designed in most areas. The most common practice followed is evaporation pools or direct discharge for drying on soil which causes severe harm and damages the soil properties affecting its quality and, subsequently deteriorating the quality of groundwater and surface water of the adjoining areas. India being an agriculture-based country has a great demand for water for irrigation purposes. The use of wastewater for irrigation purposes is quite a common practice in India resulting accumulation of toxic substances on the soil. So far there is a lack of reliable information regarding the long-term effects of YFW application on agricultural land. This study assesses the effects of YFW disposal on underlying soil properties in the wider disposal.

I. INTRODUCTION
India is an agronomical country with excessive demand for water for irrigation. Simultaneously the need for water for different industrial processes is also increasing and as a result, a large quantity of effluent is also being discharged into water bodies untreated [1]. The use of industrial effluent released from yeast factories, sugar mills, oil mills, etc. for irrigation purposes has become a common practice in India. The disposal of waste containing toxic substances has affected the agricultural soil quality gravely. Apart from this the untreated effluent has degraded the fertility of the soil and affected the food chain also adversely [2, 3]. Factories producing yeast play a chief role in contaminating the water forms and land by discharging an enormous amount of effluent. Numerous chemicals are used during the manufacturing process mainly for coagulation, removal, and refining of impurities
and the end product. A large amount of effluent is released during the production containing an appreciable amount of pollution load particularly organic matters and organic mud [4, 5]. Discharge of effluent to the land of irrigational land impacts the physicochemical properties of soil unfavorably [6, 7]. Chopra and Pathak,2013 [8] have shown that the release of effluent on irrigational land can be a source of contamination to the soil as some toxic substances may also be transferred to plants from roots to leaves. Baskaran et al have also identified the polluted soil by the industry becomes unsuitable for further cultivation of crops [9].
