In the current research, the effects of some organic fertilizers as fulvic and humic acids on the vegetative growth of pistachio seedlings in a semi-hydroponic culture containing Fe-EDDHA (as a synthetic fertilizer) and FeSO4 (as an inorganic fertilizer) were investigated. The alkalinity is recognized as a main problem in pistachio orchards, therefore the pH of nutrient solution was ...

Agroecosystem nitrogen (N) loss produces greenhouse gases, induces eutrophication, and is costly for farmers; therefore, conservation agricultural management practices aimed at reducing N loss are increasingly adopted. However, the ecosystem consequences of these practices have not been well-studied. We quantified N loss via leaching, NH3 volatilization, N2O emissions, and N retention in plant ...

A 3-year study was conducted in cornfield to evaluate how composted cattle manure application affects net global warming potential (GWP; the sum of nitrous oxide (N2O) and methane (CH4) minus net ecosystem carbon balance (NECB)) and greenhouse gas intensity (GHGI; net GWP per unit of plant biomass yield). In the first experiment, conducted from 2010 to 2012, five fertilization strategies that i...

Understanding the microbial community structure of agricultural soils is important for better soil management in order to improve soil quality. Phospholipid fatty acid analysis has been popularly used in determining the microbial community structure in different ecosystems. The microbial community structure of paddy soil under long-term fertilizer treatments was investigated after 45 years usin...

an experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (se) sources on broiler male birds (ross 308). uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental se, negative control), 0.25 ppm of inorganic se, 0.5 ppm of inorganic se, 0.25 ppm of inorganic se + 0.25 ppm of organic ...

Supplementing the nutrient requirement of crops through organic manures plays a key role in sustaining soil fertility, and crop productivity and reducing use of fossil fuels. Field experiments were conducted for 2 years at two different locations (i.e. Lucknow and Pantnagar) in Uttar Pradesh, India. The objectives of the study were to assess the herb and essential oil yields of Japanese mint (M...

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...

The growth and yield of Egusi melon in response to application of an Organo-mineral fertilizer was investigated. The Organo-mineral fertilizer was Cow-dung generated from an Abattoir fortified with inorganic Nitrogen. The fertilizer had a pH of 6.1; 61.2 g kg Organic Matter; 35.5 g kg -1 -1 Organic Carbon; 3.6g kg Nitrogen; 372.54 mg kg Available Phosphorus and 14.8cmol kg -1 -1 -1 Exchangeable...

in order to evaluate the effects of organic fertilizer complements application (aminol forte, fosnutren and kadostim) on grain yield, milling properties and nitrogen use efficiency of two rice (oryza sativa l.) cultivars, a field experiment in factorial layout and a randomized complete block design with 10 treatments and 3 replications was conducted at rice research institute of iran in 2009. t...
