Agricultural Detritus and Artistic Practices

Rapid decomposition of maize detritus in agricultural headwater streams.

Headwater streams draining agricultural landscapes receive maize leaves (Zea mays L.) via wind and surface runoff, yet the contribution of maize detritus to organic-matter processing in agricultural streams is largely unknown. We quantified decomposition and microbial respiration rates on conventional (non-Bt) and genetically engineered (Bt) maize in three low-order agricultural streams in nort...

Agricultural health in The Gambia I: Agricultural practices and developments.

This manuscript reports results of our study to characterize the historical developments of agricultural practices in The Gambia and related health risks of farm workers. It surveys the various factors that shape production agriculture in the country and examines the degrees to which hand tools, animal traction, motorized traction and manual labour all contribute to the inherent hazards of farm...

Effects of agricultural subsidies of nutrients and detritus on fish and plankton of shallow-reservoir ecosystems.

Agricultural activities increase exports of nutrients and sediments to lakes, with multiple potential impacts on recipient ecosystems. Nutrient inputs enhance phytoplankton and upper trophic levels, and sediment inputs can shade phytoplankton, interfere with feeding of consumers, and degrade benthic habitats. Allochthonous sediments are also a potential food source for detritivores, as is sedim...
