Atrazine Use and Weed Management Strategies to Protect Surface Water Quality

Atrazine can be applied to the soil surface either before or after planting, incorporated into the soil prior to planting, or sprayed on corn and weeds, postemergence. Knowing that atrazine moves predominately in solution (dissolved in water) versus attaching to soil particles aids our...

Composting of wine industry wastes and their use as a substrate for growing soilless ornamental plants

To study the process of composting of grape marc and test the resulting compost as a substrate for the cultivation of ornamental plants, six composting processes, with mixtures of dealcoholised grapevine marc and grape stalk (DM+GS) in a 1:1 ratio (v:v), were carried out in Seville (Spain) between...

Installation of a Low Cost Polyethylene Biodigester

A Biodigester refers to a technology that permits the decomposition of organic materials, mainly manure, for the production of methane gas (biogas) that can be used for cooking, lighting and as fuel for the operation of some generators and combustion engines. A biodigester is normally made out of...
