Trace element speciation of an integrated soil amendment matrix was studied with a modified BCR sequential extraction procedure. The analysis included pseudo-total concentration determinations according to USEPA 3051A and relevant physicochemical properties by standardized methods. Based on the results, the soil amendment matrix possessed neutralization capacity comparable to commercial fertili...

The effects of integrated nutrient management (INM) by municipal solid waste manure (MSWM) on wheat yield were studied in rice-wheat and cotton-wheat systems. each site was used as an independent experimental unit. Two fertilizer doses (conventional and site-specific) were applied in each of three improved techniques: chemical fertilizers, and MSWM plus chemical fertilizers with and without pes...

Plants nutrients supply from the chemical fertilizer is the key to increasing agriculture production by enhancing the land productivity. However, the demand-supply gap of fertilizers in India has increased in recent times, thereby leading to increased dependency on imports .India imports which were about 2 million tonnes in early parts of 2000 increased to 10.2 million tonnes of fertilizers in ...

Recent studies have revealed that the integrated use of organic and inorganic fertilizers on crop has not received adequate research attention. In this paper, maize is considered among the most important cereal crops in Nigeria and all over the world that has high requirement for organic and inorganic nutrients in order to obtain good quality and high yields. The application of inorganic fertil...

Background: Cattle manure (CM) is the most common organic fertilizer used by farmers. However, its usually slow decomposition leads to the use of chemical fertilizers. Therefore, experiments on nano- and micro-sized particles of CM were conducted to evaluate the possibility of accelerating its decomposition in soil. Methods: The effects of a sole application of CM in different sizes (nano-, mi...
