ome organic fertilizers are suitable for greenhouse crops and can also fit the current ways of applying fertilizers commercially. However, not much information is available on plant response, nutrient supplying power, or the environmental impact of nutrient leaching with organic fertilizers. Not surprisingly, because of their differences in the makeup, levels of success in growing acceptable gr...

Agrochemical is evolved by the contraction and combination of words agricultural and chemical, and is a generic term used for the various chemical products typically used in agriculture. Agrochemicals essentially help in intensifying crop production and to reduce the effects of pests and parasites on farm animals. Agrochemical basically refers to the broad range of pesticides and fertilizers. A...

Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be the differentiation of crops and vegetable grown under different farming systems. The objective of this study was to compare nitrogen and carbon isotope composition of organic fertilizers and manur...

Agricultural soils can contain high arsenic (As) concentrations due to specific geological contexts or pollution. Fertilizer amendments could influence As speciation and mobility thus increasing its transfer crops toxicity. In the present study, field-relevant amounts of fertilizers were applied from a cultivated field that was former ammunition-burning site. Potassium phosphate (KP), ammonium ...

introduction: citrus are one of the important orchard fruit production that after banana is second in production at the world level and every year, chemical fertilizers having most important role in increasing crops productions, but in long application of fertilizers cause soil destructions and polluting underground water. also soils of dry regions are very poor in organic matter level. nowaday...

The current guidelines of waste management are aimed at the recovery and recycling biowaste while respecting protection human health environment. recent European legislation on fertilizers provides for use digestates derived from organic fraction municipal solid (OFMSW). objectives this study were to verify fertilizing effect three types OFMSW ryegrass culture comparing mineral fertilization ev...

The aim of the investigation was to research mineral nitrogen (N min ) behavior in loamy haplic Luvisols orchards located forest-steppe zone Central Russian Upland. seasonal dynamics N (ammonium + nitrates) studied during growing seasons 2018 and 2019 field experiments with apple sour cherry. Fertilizers were applied annually spring at doses increasing from N30K40 N120K160. most important facto...

High concentrations of animal production in the United States have increased the concern about the environmental fate of phosphorus (P) in manures. We conducted a growth chamber study to develop phosphorus source coefficients (PSCs) for manures and fertilizers typically land applied and incorporated into calcareous soils of the western United States as well as to determine the potential plant P...

Large amounts of uranium, radium and radium products are redistributed throughout the environment owing to the use of phosphate fertilizers. Potential radiological impacts resulting from direct exposure, inhalation and ingestion of foods grown with fertilizers are discussed. This paper describes a simple method to measure exhalation rate of 222RN from phosphate fertilizers, clay and potatoes in...

The alkaline serine protease VCP1 of the fungus Pochonia chlamydosporia belongs to a family of subtilisin-like enzymes that are involved in infection of nematode and insect hosts. It is involved early in the infection process, removing the outer proteinaceous vitelline membrane of nematode eggs. Little is known about the regulation of this gene, even though an understanding of how nutrients and...
