Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

The growth of the human population is causing an exponential increase in need for food. Fertilizers are one most important elements to meet this increased demand and ensure global food security. Many enhanced efficiency fertilizers, such as controlled-release fertilizers (CRFs) have been developed. Although these offer many advantages over prior generations, their high cost production well unfa...

Hydrogels show potential in agriculture for overcoming issues associated with conventional fertilizers and irrigation. A combination of hydrogels would limit the loss fertilizer curb environmental impact, especially nitrogen-based compounds, addition to diminishing frequency set renewable hydrogels, based on a mixture whey proteins alginic acid were developed as soil conditioner sustained relea...

Abstract Due to the increase in horticultural production intensive techniques are needed. These generate soil degradation, since natural recovery time between crops is insufficient. The usual way solve this problem use of fertilizers, as they effective short available. Conventional fertilizers highly soluble salts, allowing their absorption by plant roots. However, dumped on soils more quantity...

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...
