What We Talk about When We Talk about Soil Health
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-11-01)
Despite a nationwide emphasis on improving soil health in the United States, current measurement protocols have little consistency. To survey assessment practices, we conducted a meta-analysis of cover crop (n = 86) and ...
Evaluating Intercropping (Living Cover) and Mulching (Desiccated Cover) Practices for Increasing Millet Yields in Senegal
Located within the Sahel region, Senegal faces several agricultural production challenges. Limited rainfall, poor soil fertility, and insufficient agronomic inputs all contribute to low pearl millet [Pennisetum glaucum ...
Fifty Years of Cereal Leaf Beetle in the U.S.: An Update on Its Biology, Management, and Current Research
(Entomological Society of America, 2011-10-01)
Cereal leaf beetle, Oulema melanopus L., is an introduced insect pest of small grains first recorded in the United States in the early 1960s. Since its introduction from Europe or Asia into Michigan, cereal leaf beetle has ...
Internationalizing the Land Grant Mission: Lessons from Senegal
(Virginia Cooperative Extension, 2018-03-20)
Discusses using the land grant university model on an international level, in this case program development in Senegal.
The Virginia Perennial Cool-Season Grass Forage Variety Report: a 3-Year Summary (2002-2004)
(Virginia Cooperative Extension, 2009)
This report is a summary of forage variety trials performed with cool-season grasses at Virginia Tech Agricultural Research and Extension Centers from 2002 through 2004.
Comparative Nutritional Quality of Winter Crops for Silage
(Virginia Cooperative Extension, 2017-02-23)
Discusses how cropping grasses and legumes planted as winter crops affects crop yield and nutrients for forage and also later affects crop yield and nutrients for corn and sorghum silage crops.
Differential responses of grain yield, grain protein content and their associated traits to nitrogen supply in soft red winter wheat
Increased application of nitrogen fertilizers has significantly raised grain yield and protein concentration in wheat. However, only 30–50% of applied fertilizer nitrogen are usually utilized by the plant. In this study, ...
Injecting Poultry Litter into Orchardgrass Hay
Traditional surface application of poultry litter leaves nutrients vulnerable to loss through volatilization and runoff. However, injection can increase capture of these nutrients in agricultural fields. Therefore, a field ...
Precision Farming Tools. Soil Electrical Conductivity
(Virginia Cooperative Extension, 2005-09-01)
Soil electrical conductivity (EC) is one of the simplest, least expensive soil measurements available to precision farmers today. Soil EC measurement can provide more measurements in a shorter amount of time than traditional ...
Precision Farming Tools: Variable-Rate Application
(Virginia Cooperative Extension, 2011-08-01)
Discusses the two basic variable-rate application technologies, map-based and sensor-based, for fertilizer, lime, weed control, and seed.
