Globally, the growing production of food commodities generates significant quantities agroindustrial residues, most which are untreated and disposed as waste through either burning, dumping into land, or unplanned landfilling, thereby causing environmental pollution, public health problems, decreased soil organic matter productivity. A literature review has been conducted on current crop residu...

This work presents an alternative for adding value to greenhouse crop residues, used (1) heating and (2) as a CO2 source. Both options are focused on agricultural production, but could be applied other applications. The influence of factors, such the air/fuel rate turbulence inside combustion chamber, is studied. Our results show that pine pellets, olive pits, tomato-crop blend latter mixed wit...

Tobacco is an important cash crop of Pakistan and tremendous amount of irrational pesticides are being used to control insect growth. The frequency of plasma pesticide residues above acceptable daily intake (ADI) and its correlation with biochemical markers for assessment of adverse health effects in the tobacco farmers at district Sawabi, Pakistan was determined. Total 109 adult males consisti...

The identification of herbicide residues on crop foliage is necessary to make crop-management decisions for weed pest control and to monitor pesticide residue levels on food crops. Electronic-nose (e-nose) methods were tested as a cheaper, alternative means of discriminating between herbicide residue types (compared with conventional chromatography methods), by detection of headspace volatiles ...

Quantification of biogenic carbon fluxes from agricultural lands is needed to generate comprehensive bottom-up estimates of net carbon exchange for global and regional carbon monitoring. We estimated global agricultural carbon fluxes associated with annual crop net primary production (NPP), harvested biomass, and consumption of biomass by humans and livestock. These estimates were combined for ...

Abstract An improved understanding of the contribution a preceding forage crop to subsequent potato can improve nitrogen (N) utilization in production. This study used two rotation experiments estimate N from labelled shoot and root red clover (RC, Trifolium pratense ), timothy (T, Phleum ) clover/timothy mixture (M) using microplots field. Forage crops were grown with 14 NH 4 NO 3 15 (98 atom ...
