Installed biofilter at a swine facility. Practices to control particulate and dust emissions associated with livestock production can be applied to animal housing and manure storage areas. This document provides an overview of various practices for each situation, highlights their advantages and disadvantages, and allows producers to make informed choices after evaluating production and economi...

In search for an efficient means of building up the carbon stock, improving fertility levels and aggregate stability tropical soils optimum crop yield, a field study was carried using different biochars comparing effects with inorganic fertilizer. The were palm bunch biochar (PBB), saw dust (SDM) rice mill husk (RMHB). Treatments consisted 10 t/ha + 0.25t/ha poultry manure (T1), (T2), (T3), 500...

Bacteriologic culturing of environmental samples taken from sources such as manure pits and egg belts has been the principal screening tool in programs for identifying commercial laying flocks that have been exposed to Salmonella enteritidis and are thus at risk to produce contaminated eggs. Because airborne dust and aerosols can carry bacteria, air sampling offers a potentially efficient and i...

Much of land-applied manure is surface-broadcast or incorporated to a shallow depth of fields under crop Dissolved N and P transfer to runoff water may increase with residue and conservation tillage management because of surface applications and shallow soil incorporation of animal manure. Information is needed regarding water-extractable nutrient release the need to conserve stored soil water ...

the impacts of dust and sand storms (dss) on people, crops, livestock, infrastructure and health are well documented. data have accumulated on the deleterious effects of dust aerosols when they settle on plants. sand blasting of low growing plants is a common cause of failure in reforestation efforts. burial of plants by moving sands are also a cause of much damage. the physics of moving sand a...

The technology of road construction is subjected to changes to cope up with changing vehicular pattern, construction materials and sub grade condition. Majority of the pavement failures could be attributed to the presence of poor sub grade conditions and expansive sub grade is one such problematic situation. Marine soils, because of the specific physico-chemical makeup are subjected to volume c...
