The effects of various organic manure [farm yield manure (FYM), sewage sludge and poultry manure] application on adsorption-desorption of three carbamate pesticides [oxamyl(I);S-Ethyl-Nmethylcarbamoyl)oxy]thioacetimidate (II) and N-Phenyl (ethyl carbamoyl) propyl carbamate (III) on six soil samples of Aligarh district was studied. Addition of organic manure increased soil organic carbon content...

a two year field experiment was carried out to evaluate the effects of municipal waste compost (c), composted cattle manure (m), and nitrogen (n) on growth and composition of weeds in a corn field in shiraz using a split-split plot design with 3 replicates. visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...

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...

A survey of storm runoff fecal coliform bacteria (FCB) from working farm and ranch pastures is presented in conjunction with a survey of FCB in manure management systems (MMS). The cross-sectional survey of pasture runoff was conducted on 34 pastures on five different dairies over 2 yr under varying conditions of precipitation, slope, manure management, and use of conservation practices such as...

Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa) manure has been implicated in eutrophication. Dietary modification and manure amendments have been identified as best management practices to reduce P runoff from manure. This study was conducted to compare the effects of dietary modification and aluminum chloride (AlCl3) manure amendments on reducing P in swine manure and run...

Swine manure slurries were ozonated at a dosage of 1 g/L and tested for their toxicity to the house fly (Musca domestica). The observed toxicity of ozonated swine manure was consistent and independent of origin of the swine manure. A dose (dilution) response curve was performed. A 50% dilution in the ozonated swine manure slurry resulted in 90% reduction in toxicity. Neither the synthetic nor o...

Chemical treatment of animal manure with Al, Fe, and Ca salts appears capable of concentrating P in a smaller volume, thereby providing increased manure management options. However, little information is available on the fate of nutrients in soils receiving chemically treated manure. An incubation study (1 d to 2 yr) was conducted with three soils (Soils I, II, and III with 12, 66, and 94 mg kg...

Stable flies are blood-feeding insects with a great negative impact on animals world wide. Larvae develop primarily in animal manure and bacteria are essential for larval development; however, the principle of this dependence is not understood. We hypothesized that as the microbial community of animal manure changes over time, it plays an important role in stable fly fitness. Two-choice bioassa...

The use of solid dairy manure for sugarbeet production is problematic because beet yield and quality are sensitive to deficiencies or excesses in soil N, and soil N availability from manure varies substantially depending on the year of application. Experimental treatments included combinations of two manure rates (0.33 and 0.97 Mg total N ha−1) and three application times, and nonmanure treatme...
