Porcine production in China represents approximately the 50% of the worldwide pig production. Information about pig husbandry characteristics in China and manure properties from sows to fatteners in intensive pig farms are not broadly available for scientific studies as it is a time consuming, expensive task and highly inaccessible. This study provides a report about solid pig manures (28% dry ...

Slow pyrolysis or carbonization promotes the conversion of animal manures such as swine manure into charcoal. In this paper, the carbonizing kinetics of swine solids taken from different treatment stages were investigated with a thermogravimetric analyzer. Compared to their biologically stabilized counterpart (lagoon sludge) with an activation energy of 160 kJ mol(-1), the activation energies f...

This study investigated the optimum mixture ratio of greenhouse tomato plant residues, wheat straw, and separated dairy manures for composting. Five 127-L laboratory-scale bioreactors were used to investigate the effect of separated dairy manure addition on the composting process of a tomato plant residues-wheat straw mixture. The wastes were mixed at 5 different ratios during the trials and we...

Coleus forskohlii L. is an important medicinal plant species found in tropical regions of India. Roots and tubers are used for treating a variety of purposes, including treating asthma, bronchitis, insomnia, epilepsy and angina.Due to diverse use, the species has been largely exploited from natural habitat leading to its threatened status. A field experiment was conducted to study the influence...

fate) reduced WEP concentrations in the litter relative to untreated chicken litter. Similarly, when alum-treated Water-extractable P (WEP) in manure is increasingly used as an and untreated litters were broadcast onto pastures, difenvironmental indicator as it is correlated with P in runoff from soils recently amended with manure. Little information exists on WEP ferences in dissolved P concen...

in order to study the effects of different levels of cow and chicken manure and elemental sulfur (s) on availability of plant nutrients and their uptake by corn (zea mays l.), a factorial experiment was conducted using a completely randomized design and three replication. experimental treatments were three levels (0, 10 and 20 ton ha-1) of cow and chicken manures, and three levels (0, 0.25% and...
