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 ...
in order to evaluate the effects of organic, biological and chemical fertilizers on yield and yield components of milk thistle (silybum marianum l.), an experiment was conducted at the research station of ferdowsi university of mashhad based on complete randomized block design with three replications and six treatments during year 2007. treatments included inoculated seeds with azotobacter, com...
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...
In order to explore the influences of sheep manure mixed with chemical fertilizers upon yield and quality maize spatial temporal distribution soil inorganic nitrogen under wheat-maize rotation system, achieve increased efficiency rational fertilization in this area, at same time provide a reasonable scientific basis for green production, an experiment was performed Wanbei Comprehensive Experime...
In order to investigate effect of application of Nitroxin and nitrogen chemical fertilizer on yield and yield components, split plot experiment on the basis of Randomized Complete Block Design with four replications was conducted. Four levels of Nitrogen fertilizer (N1: 100% chemical fertilizer, N2: 75% chemical fertilizer + 100% biological fertilizer, N3: 50% chemical fertilizer + 100% biologi...
Crop yields, soil fertility, and quality decline due to the overuse of chemical fertilizers other agrochemicals. The damaging effects these agrochemicals on environment can be minimized by integration with eco-friendly approaches, i.e., biofertilizers. These biofertilizers containing plant growth-promoting rhizobacteria, (PGPR) not only solubilize mineral nutrients for crop uptake but also rele...
