Improving food grain production by enhancing plant nutrient availability is critical for meeting future production. In this line, degraded soils may have the potential to meet the food demand of future population. However, the key challenge is excessive concentration of salts. It adversely mediates the soil fertility parameters, physical properties and soil enzymatic activities. Addition of organic substances, such as farm yard manure (FYM) and pressmud (PM), may improve soil health parameters. An incubation experiment was conducted with graded application of FYM (0, 2.5, 5 and 10 t/ha) and PM (0, 2.5, 5 and 10 t/ha) to monitor the nutrient release pattern of FYM and PM; and its effect on soil physico-chemical properties and soil enzymatic activities. The results showed that soil pH and EC were reduced after the one year incubation period. It was also observed that available plant nutrients like N, P, K, S and soil enzymatic activities reported highest in treatment FYM and PM (each applied 10 t/ha) over control. The findings of this study suggested that organic amendments can improve soil fertility, mitigate salt ion toxicity, and enhance food production potential, particularly in arid and semi-arid soils.
通过提高植物养分有效性来增加粮食产量对于满足未来粮食生产至关重要。在这方面，退化土壤可能有潜力满足未来人口的粮食需求。然而，关键挑战是盐分浓度过高。它会对土壤肥力参数、物理性质和土壤酶活性产生不利影响。添加有机物质，如农家肥（FYM）和滤泥（PM），可能会改善土壤健康参数。进行了一项培养实验，对FYM（0、2.5、5和10吨/公顷）和PM（0、2.5、5和10吨/公顷）进行分级施用，以监测FYM和PM的养分释放模式；及其对土壤理化性质和土壤酶活性的影响。结果表明，经过一年的培养期后，土壤pH值和电导率降低。还观察到，在处理FYM和PM（各施10吨/公顷）中，有效植物养分如氮、磷、钾、硫和土壤酶活性比对照中最高。本研究结果表明，有机改良剂可以提高土壤肥力，减轻盐离子毒性，并提高粮食生产潜力，特别是在干旱和半干旱土壤中。
