Few studies have been conducted to investigate the potential contamination of groundwater from manureborne steroid hormones. The objective of this study was to monitor leaching of steroid hormones at the bottom of 2.4 m deep percolation lysimeters installed in plots treated with beef cattle manure. Soil samples were also collected from surrounding field plots. Treatments consisted of applicatio...
Manure or compost from beef cattle feedlots can be excellent sources of nutrients and organic matter when added to soils. This study was conducted to determine the effect of a single application of manure and compost on runoff and erosion under no-till and tillage conditions. Tillage consisted of a single disking operation up and down the slope on a Sharpsburg soil which was cropped to grain so...
The main objective of this study was to determine the effects of Nitrogen fixing bacteria and manure application on the seed yield and yield components in black cumin (Nigella sativa L.). The experiment was carried out at the RAN Research Station in Firouzkouh in 2012. A 4×4 factorial experiment, arranged in a randomized complete blocks designed with three replications. The treatments ...

the role of manure and urea on yield and some fruit characteristics of strawberry cv. kurdistan were studied during 2002-2004 growing season. the experiment was a factorial one based on a randomized complete block design including four levels of urea(0, 50, 100, 150 kg/ha) and three levels of manure (0, 20, 40 t/ha) in three replications. the results showed that application of manure along with...
in order to study the effect of different levels of the manure and foliar application of zn and mn fertilizers on the quantitative and qualitative yield of soybeans (var. williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two levels of mn...
Cropping systems in farmland areas of Iran are characterized by continuous cultivation of crops with consumption of chemical fertilizers leading to serious soil erosion and fertility decline. Information regarding the simultaneous evaluation of crop rotation and fertilization on the canola traits is not available. Therefore, an experiment was conducted during 2007 2010. Experimental designs wer...
A field experiment was conducted to investigate effects of four organic manure sources (vermicompost, poultry manure, sheep & goat manure and cattle FYM) on growth and yield attributing characters of garlic in greenhouse condition during extreme winter months (October to May) at Leh-Ladakh, India with three application rates of organic manures viz. 10, 20 and 30 tons ha-1. The results revealed ...
Land application is the most common method for utilizing manure produced by the livestock industry. Manure applications at rates that exceed crop P removal are increasing soil-test P (STP) in many regions. Precision agriculture methods and variable-rate (VR) application can improve nutrient management and provide an environmentally responsible method to distribute manure. This study used a stri...
Fertilization of crops with pig manure is a common practice throughout the world. Nevertheless, due to the relatively high copper (Cu) and zinc (Zn) contents in pig manure, continuous application of pig manure could have negative effects on soil and plant. The study aimed at the impacts of long-term applying different pig manure rates (equivalently 0, 100, 250 and 500 kg total N/ha/year from 20...
