Yield and Soil Nutrient Changes in a Long-Term Rice-Wheat Rotation in India

Refinement of fertilizer recommendation based on Soil Test Crop Response technology for rice under System of Rice Intensification

“…It's an important major crop in Tamil Nadu and is accounted for 29.3 per cent (1.73 mha) of the total cropped area with total production of 7.1 million tones (Season and Crop Report, 2015). Over-exploitation of soils over many decades has resulted in the exhaustion of the agricultural production systems and steadily declining productivity has been noticed in long term experiments in Asia (Bhandari et al, 2002;Ladha et al, 2003;Manna et al, 2005). The decision on fertilizer use requires knowledge of the expected crop yield response to nutrient application, which is a function of crop nutrient needs, supply of nutrients from indigenous sources, and the short and long-term fate of the applied fertilizer nutrients (Dobermann et al, 2003).…”

Impacts of agricultural land management on soil quality after 24 years: a case study in Zhangjiagang County, China

“…Land use change from dry land to rice paddies also usually improves soil quality (Bhandari et al 2002). Smallholder farm communities often improve soil quality indirectly by increasing the active participation of farmers (Mowo et al 2006;Huang et al 2007).…”

Effect of INM on Soil Carbon Pools, Soil Quality and Sustainability in Rice-Brown Sarson Cropping System of Kashmir Valley

“…However, application of fertilizers and manures resulted in significant improvement in the buildup of the available N content of subsurface soil. So, it is clear that application of organic manures in conjunction with chemical fertilizers increased the available N in soil is attributed to the increase in total SOC that might have been partially due to a slow release of N from straw and manure as suggested by Yadav et al, (2000), Gami et al, (2001) and Bhandari et al, (2002). Farmyard manure and straw is known to stimulate biological N 2 fixation in the soil, which may also have been responsible for the increase in soil N (Ladha et al, 1989) over NPK treatment, apart from FYM's own N contribution.…”
