In order to investigate the effect of sugarcane compost on consumption of nitrogenous fertilizers in corn fields, a research project was conducted according split plot experiment based on randomized complete block design with three replications along 2015 year. The main plot included different chemical nitrogenous fertilizer (Zero; control, 60 and 120 kg.ha-1 pure nitrogen from urea ...

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 ...

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...

yazd asfordi phosphate rock (pr) was partially acidulated at five levels (0, 40, 60, 80, 100%) for increasing the relative agronomic effectiveness (rae) of canola (brassica napus l.), var. rgs in two calcareous and non-calcareous soils. the partially acidulated phosphate rock (papr) was compared vs. the standard fertilizer (triple superphosphate) in two levels (50 and 100 mg p/kg). this study w...

wheat is a staple food in pakistan. production of wheat is increased with extensive use of phosphate based fertilizers in agricultural fields. activity mass concentration of primordial radionuclides due to use of phosphate fertilizers in soil enhances the external gamma dose and due to the consumption of wheat food grown on these soils also increases the internal dose. different types of soil, ...

long-term application of fertilizers containing p, especially organic fertilizers, usually increases the water soluble and available p of soil and at the same time may result in p accumulation in soil. organic fertilizers may also increase movement of p in the soil profile that could result in surface and ground water pollution. an experiment was conducted on field plots that received three app...
