the aim of this study was to determine the optimum mixture ratios for composting separated cattle manure and pepper plant residues. five 127 liter laboratory-scale bioreactor were used to investigate of separated dairy manure addition on the composting process of greenhouse pepper plant residues. cattle manure is considerably rich in nitrogen. however, composting with cattle manure alone is not...

Due to high production of organic residues such as sewage sludge and compost, land application is probably the best way to prevent accumulated residues in the environment. However, the risk involved in the land application of organic residues should be evaluated prior to the assessment of their economic and fertilizer values. The objective of this study was to evaluate the effect of organic res...

The impacts of two organic soil amendments on nematode abundance, community structure and soil characteristics were studied in field grown tomatoes. We hypothesized that as the raw (labile form) and composted (non-labile form) manures differ in their chemical composition and effect on microbial activity. Also they will have different effects on soil properties and directly and indirectly affect...

Prediction of phosphorus (P) availability from soil-applied composts and manure is important for agronomic and environmental reasons. This study utilized chemical properties of eight composted and two non-composted beef cattle (Bos taurus) manures to predict cumulative phosphorus uptake (CPU) during a 363-d controlled environment chamber bioassay. Ten growth cycles of canola (Brassica napus L.)...

in order to study the effect of different types and rates of animal manure and spent mushroom compost on controlling egyptian broomrape (orobanche aegyptiaca perss.) in tomato (mill. lycopersicon esculentum), two studies were conducted on randomized complete block design with three replications at research green house, college of agriculture, ferdowsi university of mashhad and nemooneh field of...

lar amounts of total P as TC, but a larger proportion of that P exists as phosphate rather than phytate (Ertl Swine (Sus scrofa) slurry can serve as an excellent fertilizer source. et al., 1998). Bioavailability of P in LPC is higher than Application at rates to meet crop N requirements can result in excess soil P due to low manure N/P ratios. Low phytate corn (LPC) (Zea in TC for nonruminant a...

Improper tillage with no manure may cause a range of undesirable processes (destruction of soil structure, accelerate erosion, depletion of organic matter and fertility). A field experiment was conducted to observe the change in soil properties after incorporation of green manure crops and to find out the residual effect of green manure crops along with tillage on maize and rice yields during 2...

This study was carried out in the Teaching and Research Farm of Delta State University, Asaba Campus from March 2008 to December 2009 to evaluate the effects of previously applied amendments on maize grain weight and some soil properties. The experiment was carried out in a Randomized Complete Block Design (RCBD) replicated three times in a factorial layout. Four different rates of poultry drop...

Two field experiments were carried out during the summer seasons of 2001 and 2002 at the Experimental Station Farm of the Faculty of Agriculture, Alexandria University, at Abeis, to study the effects of four treatments of organic manure (unmanured, chicken, compost and cattle) and three biofertilizer treatments (uninoculated, Halex 2 and Nitrobein) on vegetative growth, yield potential and chem...

Animal manure contains partially digested feed fiber and grains where phosphorus (P) is bound in organic compounds that include myo-inositol 1,2,3,5/4,6-hexakis dihydrogenphosphate or phytic acid (IP6). Information is needed on the effects of other (non-IP6) organic ligands (LIGND) on the enzymatic dephosphorylation of IP6, which is a potential source of dissolved orthophosphate P (PO4-P) in th...
