ABSTRACT

Soil health refers to its functionality and ecological equilibrium. Different indicators of soil health include its physical, chemical, biological, and biochemical attributes. The present study was undertaken to check the stress generated on the addition of urea in five different soils, sampled from various regions of state Haryana. The change in pH and urease activity was observed on urea treated soil, fertilized with two potential urease inhibitory plant extracts, Cassia fistula and Phyllanthus niruri. Urea incorporation raised the pH and urease activity of all soil types. Plant extracts fertilization positively regulated both attributes of all soil samples. Although Cassia fistula possessed excellent in vitro urease inhibitory potential as compared to Phyllanthus niruri, but for soil health Phyllanthus niruri and formulation Cassia fistula + Phyllanthus niruri (10:90) proved significantly better.

摘要

土壤健康是指其功能和生态平衡。土壤健康的不同指标包括其物理、化学、生物和生化属性。本研究旨在检查从哈里亚纳邦不同地区取样的五种不同土壤中添加尿素时产生的应力。在尿素处理的土壤上观察到 pH 值和尿素酶活性的变化，土壤用两种潜在的尿素酶抑制植物提取物Cassia fistula和Phyllanthus niruri 施肥。尿素掺入提高了所有土壤类型的 pH 值和尿素酶活性。植物提取物施肥对所有土壤样品的这两个属性都有积极的调节作用。虽然决明子瘘具有优良的体外与Phyllanthus niruri相比具有脲酶抑制潜力，但对于土壤健康而言，Phyllanthus niruri和配方Cassia fistula + Phyllanthus niruri (10:90) 被证明明显更好。
