The composting industry has been growing rapidly in China because of a boom in the animal industry. Therefore, a rapid and accurate assessment of the quality of commercial organic fertilizers is of the utmost importance. In this study, a novel technique that combines near infrared (NIR) spectroscopy with partial least squares (PLS) analysis is developed for rapidly and accurately assessing comm...

a field experiment was conducted to study the effect of two organic fertilizers along with zinc and boron elements on some growth parameters, concentration and uptake of nutrients in millet (panicum miliaceum l.) by using factorial based on randomized completely block design with three replications in qaen region, iran. the main treatments were municipal solid waste compost and cow manure (each...

The activity concentration of naturally occurring radionuclides K, Ra and Th have been measured in different brands of fertilizer samples in Saudi Arabia using sodium iodide gamma spectrometry. The results of measurements showed that the mean (ranges) of specific activities for Ra, Th and K activities in the nitrogen, phosphorus and potassium fertilizers are 64 (35.8 120.7), 17 (3.2 56.8) and 2...

Agriculture accounts for a large percentage of nitrous oxide (N2O) emissions, mainly due to the misapplication nitrogen-based fertilizers, leading an increase in greenhouse gas (GHG) footprint. These emissions are direct nature, released straight into atmosphere through nitrification and denitrification, or indirect nitrate leaching, runoff, N2O volatilization processes. largely ascribed agricu...

abstractbackground and objectives: satureja khuzestanica is valuable and endemic medicinal specie that growing widely in southwest parts of iran. this specie is rich of phenolic compound carvacrol, therefore have considerable biological activities. satureja khuzestanica is a new medicinal plant in iran, and little research has been done on. thus, the present study with the aim of evaluating the...

damping-off disease of cucumber caused by soil-born fungi pythium aphanidermatum is one of the most destructive diseases of cucumber. in this research, the effect of three bio-fertilizers including; nitroxin, mycorrhiza and vermicompost in single and combined form on induced resistance and yield components in greenhouse cucumber (es-2862) infected with damping-off disease was investigated. thes...

in order to study the effects of integrated application of bio-fertilizer and chemical fertilizers on yield and yield components of corn, an experiment was conducted in 2008 in dezful city, (khoozestan province) in a factorial arrangement based on complete randomized block design with four replications. treatments were integrated application of biological and chemical fertilizers in four levels...
