Dr. Bill Robertson, extension cotton specialist for Arkansas, offers 7 points of advice for growers to consider when planning cover crop strategies for the fall.

With cover crops growing in popularity, it’s not uncommon to see a field full of green in early April. Planting corn or soybeans into rye or other winter crops has some benefits. However, recent research from Iowa State University suggests not terminating cover crops ahead of planting could bring more disease and pests that may overwinter or start early.

To help understand cover crop decomposition and N release throughout the growing season, University of Nebraska researchers designed a study using “litterbags” — a common method to research crop decomposition. This research is part of the Precision Sustainable Agriculture (PSA), a collaborative project supported by the Agriculture and Food Research Initiative’s Sustainable Agricultural System Coordinated Agricultural Projects from the United States Department of Agriculture (USDA).

Scott Shriver, one of Iowa's leading organic farmers, recently conducted research to determine optimal soybean row-width and seeding dates when roller-crimping cereal rye. The soybeans he planted the day of roller-crimping ultimately yielded higher than those planted 13 and 17 days before.

In this Practical Farmers of Iowa blog, ISU graduate student and researcher Dana Jokela writes about using a roller-crimper to terminate cereal rye.

The study looked a pumpkin plots in Kansas, where the Halloween staple is frequently grown in rotation following soybeans, and are a staple of agritourism, according to the study published in the Soil Science Society of America Journal.
