Excessive consumption of nitrogen (N) to enhance production, which may lead to environmental pollution. While sustainable production is threatened due to low soil fertility and organic matter. This study was carried out as a factorial experiment in the randomized complete block design and three replications at the research field of the University of Jiroft in 2018-2019. The present study invest...

background and objectives: soybean is one of the plants that need large amounts of nitrogen for grain yield production. todays bio-fertilizers are considered as a best replacement for chemical nitrogen to increase soil fertility and sustained agricultural production. meanwhile, the use of soybean symbiotic bacteria and nitroxin, which contain the most effective nitrogen-fixing bacteria of the g...

Abstract:Ensuring food security, increasing farmers’ income and improving people’s living standards are the focus of attention all countries in world today. “Centrey Tianwang” biological organic fertilizer has been upgraded to multi-functional innovation, accepted as a new invention patent. multifunctional is long-term natural with high concentration. It kind slow-release fertilizer, both quick...

nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...

The main purpose of this paper is to evaluate the effect of crude oil price on global fertilizer prices in both the mean and volatility. The endogenous structural breakpoint unit root test, ARDL model, and alternative volatility models, including GARCH, EGARCH, and GJR models, are used to investigate the relationship between crude oil price and six global fertilizer prices. The empirical result...

Introduction ield experience and research demonstrate that manure nutrients can be readily substituted for commercial fertilizer. Fertilizer needs depend on soil test levels. Substituting manure at a lower cost than commercial fertilizer can result in signifi cant savings if relatively uniform application and distribution can be maintained. The less nutrient-dense manure requires more hauling o...

With the goal of improving N fertilizer management to maximize soil organic carbon (SOC) storage and minimize N losses in high-intensity cropping system, a 6-years greenhouse vegetable experiment was conducted from 2004 to 2010 in Shouguang, northern China. Treatment tested the effects of organic manure and N fertilizer on SOC, total N (TN) pool and annual apparent N losses. The results demonst...
