Faced with limited comprehensive data on the economic, agronomic, and environment effects of land-applying animal wastes, water quality models are increasingly used to explore management and policy alternatives. However, thorough evaluation of these

Field studies were conducted at four locations in Texas over a two year period to assess the response of five peanut cultivars to inoculation with four species of vesicular-arbuscular endomycorrhizal fungi (VAMF) with or without Bradyrhizobium sp., a

Precipitation is limited in the Southern Great Plains, and farmers must minimize production costs and control erosion. The purpose of this research was to determine economic feasibility of dryland no- and reduced-tillage systems compared with sweep p

Researchers at Texas A&M University have studied properties of cattle biomass (CB or manure) fuels and their possible utility in combustion systems. Larger, more concentrated animal feeding operations (CAFO) and farms make manure disposal more diffic

Irrigated winter barley (Hordeum vulgare L.) can be a profitable alternative to some low profit major crops in the Texas High Plains. A six-year evaluation of yield response related to total spring irrigation water, applied by surface methods (furrow

(…) A 45 mm increase in soil water storage with no-tillage increased dryland cotton yields 110 kg ha −1 . Although herbicide costs were $155.00 ha −1 greater with no-tillage, long-term annual profit with no-tillage increased $82.00 ha −1 over
