The environmental problems caused by sewage sludge generated the growth of global population and urbanization are drawing attention scientific community worldwide to need developing sustainable solutions use that material. This work investigated possibilities using sludge, in wastewater treatment plants, as a strategy improve stabilize collapsible soils. Different soil–sludge mixtures, with 5%,...

This study investigates the effects of mucilage from Opuntia ficus-indica cladode (MOFIC), a bio-modifier, on Lime-stabilized Lateritic soil's durability and index features. Specifically, this research assessed alterations to Atterberg limits, compaction characteristics, California bearing ratio (CBR), values unconfined compressive strength (UCS) properties soil samples stabilised through labor...

In the face of an oversupplied world pig market only the most efficient producers will stay in business. By and large these will be the operations that are able to more successfully exploit the genetic potential of their animals. Similarly, only those breeders who are able to demonstrate sustained genetic improvement will sell stock to the smaller number of large producers who are left. Althoug...

Soil fertility improvement is an important area which needs attention since most of the hazardous inputs added into the agricultural system are in the form of chemicals. Since crop production and soil normal flora are affected by input of chemical fertilizer. Biofertilizer microorganisms make the nutrients available to plants. The present study was concerning to isolate of some Pseudomonas fluo...

The black cotton soil is a type of problematic expansive soil which causes many problems in the construction of structures founded on them. It is having a swelling and impervious nature with poor geotechnical subgrade characteristics. In this research an approach is made towards the way of improvement in the various geotechnical properties of black cotton soil such as index properties, swelling...

Introductions of high yielding inorganic fertilizer are not cheap and leave behind a large amount of dry matter for disposal. Thus there is a need to utilize these plant residues to save fertilizers and maintain a satisfactory level of soil fertility. Hence, with the view of in-situ manuring as well as to recycle the agricultural residue, pot experiments were conducted to study the effect of wh...
