Cover crops are planted not for harvest, but are designed to maintain and enhance the sustainability of a production system by improving soil fertility, water quality and can lead to the suppression of weeds, soil erosion and pests. This publication provides information on how to use short duration cover crops to aid production, especially during a fallow period between two vegetable crops. Choosing the correct cover crop will impact its effectiveness, as will the grower'€™s method of seeding and termination.
Managing Spotted Winged Drosophila in Commercial Fruit Production
Fruit flies native to the U.S. primarily lay eggs in soft, rotting fruit and cause little to no economic loses to undamaged fruits. These fruits flies are considered a nuisance pest to farmers unless the fruit has been previously injured. Spotted winged drosophila (SWD), Drosophila suzukii, on the other hand, is an invasive fruit fly that prefers to lay eggs in healthy, maturing fruit. It is native to Southeast Asia including China, India, Japan, Korea, and Thailand (Walsh et al., 2011), where the climate is similar to the Midwest.

Organic Turfgrass Fertilization
Increased environmental concerns surrounding soluble nitrogen sources have forced many to reconsider organic fertilizers. Organic fertilizers, as well as slow-release synthetic sources, release small amounts of nitrogen over long periods. University research from across the country has concluded that when applied correctly, organic and slow-release products will reduce environmental impact.
Conservation Techniques for Vegetable Production: Combining Strip-Tillage and Cover Crops
Strip-tillage is when a crop is planted into narrow, tilled strips and the non-tilled area between the strips might contain residue from the previous season's main crop or a living or dead cover crop.
 Combining strip-tillage and cover crops offers various benefits including minimal soil erosion, maintains soil moisture and weed suppression. This publication provides basic information on using a strip-tillage system with rolled cover crops as a conservation best management practice in vegetable production systems such broccoli, peppers, pumpkins, squash and tomatoes.
