We tested the efficacy of matrix-based fertilizers (MBFs) to improve Kentucky bluegrass (Poa pratensis L.) growth while reducing NH, NO3, dissolved reactive phosphorus (DRP), and total phosphorus (TP) compared to commercial slowrelease fertilizer (SRF) Polyon®, ESN®, and Avail® in greenhouse column studies. The MBFs covered a range of inorganic N and P in compounds that are relatively loosely b...

Growing fruit trees on the slopes of rolling hills in South China was causing serious environmental problems because of heavy application of chemical fertilizers and soil erosion. Suitable sources of fertilizers and proper rates of applications were of key importance to both crop yields and environmental protection. In this article, the impact of four fertilizers, i.e., inorganic compound ferti...

The influence of organic amendments and inorganic fertilizers on cabbage head was investigated to determine their effect on storage behavior and organoleptic quality. Field cabbage was raised by combining fourteen different treatments comprising of organic amendments and inorganic fertilizers at different levels. The result showed that nutrient schedule of the crop significantly influenced the ...

Orthophosphate (Pi) is an essential macronutrient that plays a central role in virtually all major metabolic processes in plants, particularly photosynthesis and respiration. Many metabolites are Pi monoesters, whereas the phosphoanhydride bonds of compounds such asATP function to transfer energy from the energyyielding process of photo-, oxidative, and substratelevel phosphorylation to the ene...

Two field experiments were conducted at Sakha Research Station, Kafr El-Sheikh Governorate, Egypt during 2012/2013 and 2013/2014 seasons, to study the effect of mineral and bio-fertilizers as well as their combinations on morphology, anatomy, yield and quality of sugar beet. Bio-fertilizers were phosphorine, cerealine and yeast; however, mineral fertilizers were 50, 75 and 100% from recommended...

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during November 2011 to March 2012 to evaluate the effect of integrated use of manures and fertilizers on the growth, yield and nutrient uptake by wheat. There were six treatments such as T0 (Control), T1 [STB-CF (HYG)], T2 [CD + STB-CF (HYG)], T3 [PM + STB-CF (HYG)], T4 [COM + STB...

iran is among the biggest emitters of greenhouse gasses in the world. agricultural sector has a remarkable role in non-renewable energy consumption and then, the environmental impacts in this country. in this regard, the environmental impacts of watermelon production as the most important melons produced in guilan province of iran were investigated through the life cycle assessment (lca) approa...

to evaluate the effect of foliar application of nano iron chelate and iron chelate fertilizers on morphological traits and essential oil content of holy basil, an experiment was conducted at research farm of department of horticultural, shahid chamran university of ahvaz based on randomized complete blocks design with six treatments and three replications. the treatments were including control,...

The USDA established the National Organic Program (NOP) to develop national standards for organically produced agricultural products and establish an organic certification program as required by the Organic Foods Production Act (OFPA) passed by Congress in 1990. Organic crop production excludes conventional pesticides, petroleum – based fertilizers, and sewage sludge based fertilizers with some...
