The novel hydrogels were synthesized by grafting guar gum with acrylic acid and cross-linking with ethylene glycol di methacrylic acid (EGDMA). The synthesis of hydrogel was confirmed by characterization through ¹³C NMR, FTIR spectroscopy, SEM micrography, thermo-gravimetric analysis and water absorption studies under different solutions. Synthesized hydrogel (GG-AA-EGDMA) was confirmed to be biodegradable with half-life period of 77 days through soil burial biodegradation studies. The effects of hydrogel treatment on soil were evaluated by studying various physico-chemical properties of soil like bulk density, porosity, water absorption and retention capacity etc. The hydrogel which could absorb up to 800 ml water per gram, after addition to soil, improved its porosity, moisture absorption and retention capacity significantly. Water holding capacity of water increased up to 54% of its original and porosity also increased up to 9% of its original. The synthesized hydrogel revealed tremendous potential as soil conditioning material for agricultural applications.

通过将瓜尔胶与丙烯酸接枝并与乙二醇二甲基丙烯酸（EGDMA）交联来合成新型水凝胶。水凝胶的合成通过¹³的表征得到证实在不同溶液下的13 C NMR，FTIR光谱，SEM显微照片，热重分析和吸水率研究。通过土壤埋藏生物降解研究，证实合成的水凝胶（GG-AA-EGDMA）具有半衰期77天可生物降解。通过研究土壤的各种物理化学性质，如堆积密度，孔隙率，吸水率和保水能力等，评估了水凝胶处理对土壤的影响。添加到土壤中后，每克最多吸收800毫升水的水凝胶得到了改善其孔隙率，吸湿性和保留能力显着。水的持水量增加了其原水的54％，孔隙率也增加了其原水的9％。
