There seems to be conflicting information about foliar fertilizers and their timing of application to cotton. Much of the confusion lies in the variety of fertilizer products available. A cotton fanner now has a choice of applying foliar fertilizers (according to fertilizer labels) beginning at the first true leaf stage and continuing until defoliation. This newsletter will focus on available i...

The research on evaluating the biological efficiency of Lifeline, WS herbicide (glufosinate ammonium, 280 g/l), UPL Holdings Ltd, Netherlands, was carried out in field experiments near trunk lanes apple garden.
 It’s established that with a three time application to fruit plants dose 1,1 and 1,8 l/ha showed high against perennial annual weeds (100 %). By harvesting garden were free weed pl...

The purpose of the research is to study effect and interaction straw-litter compost (20 t/ha), ammonium nitrate (30 kg/ha N) microfertilizer Azosol 36 Extra (2 times 2 l/ha) on fertility indicators typical chernozem for soybean cultivation in southern forest-steppe Central Chernozem region. It was found that increase fertilization level based use contributed positive dynamics organic matter mac...

High nitrate concentrations in salads and vegetables have attracted increased attention. It is well know that nitrate can cause serious health problems to humans such as methemoglobinemia of infants 111. Under certain conditions, specially in the human body carcinogenic nitrosamines can be formed [2]. However, nitrate content of different types of vegetables fluctuates substantially with variet...

The article presents an analysis of the effectiveness mineral fertilizers in arid conditions Saratov Left Bank. Conducted studies on fertilization crops: winter wheat, rye, chickpea and sunflower showed that application ammonium nitrate before sowing doses 110–130 kg/ha physical weight increases yield wheat by 0.13 t/ha, or 14.7%; rye – 0.33 19.2%; - 0.08 14.2%, 14.7%. It is noted efficiency mo...

phosphorus is one of the most important nutrients for plant growth and development. chemical pi fertilizer is used to provide the phosphorus for the plants, but it is mostly fixed in the soil into insoluble form and become unavailable to the plants. phosphate-solubilizing bacteria have lots of application in agriculture as biological fertilizer. consumption of biofertilizers instead of chemical...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

Zinc oxide (ZnO) nanoparticles may provide a more soluble and plant available source of Zn in Zn fertilizers due to their greater reactivity compared to equivalent micron- or millimetre-sized (bulk) particles. However, the effect of soil on solubility, spatial distribution and speciation of ZnO nanoparticles has not yet been investigated. In this study, we examined the diffusion and solid phase...

Field experiments were conducted to study the effect of organic matrix based slow release fertilizers (SRFs) on plant growth, nitrate assimilation and seed yield of Brassica juncea L. cv, pusa bold. The agro-waste materials like cow dung, clay soil, neem leaves and rice bran were mixed together in 2:2:1:1 ratio and used as organic matrix for the immobilization of chemical fertilizer nutrients w...
