High biomass cover crops are effective in controlling weeds in vegetable production, while contributing to higher produce yields, Auburn University researchers have found. In addition, pre-emergence herbicide applications can be eliminated from weed management programs in the presence of heavy residues from cover crop mixtures. Read more in this article from the Sustainable Agriculture Research & Education (SARE) program.

Some cover crops, coupled with soil solarization, can control soil-borne diseases in nursery field production of woody ornamentals, according to the results of a Southern Sustainable Agriculture Research and Education (SSARE)-funded Tennessee State University study. Through a $15,000 SSARE On-Farm Research Grant, Fulya Baysal-Gurel of TSU’s Otis L. Floyd Nursery Research Center, and her colleagues assessed the effects of certain cover crops that belonged to the Brassicaceae family on soil-borne pathogen Phytophthora nicotianae in boxwoods.

The best management practice to reduce the resistant rootworm population is to rotate out of corn for at least one year. If that field is rotated to a non-host crop (e.g. alfalfa, rye, triticale, sorghum-sudangrass) in the following year, the larvae will die after hatching, and the population will be eliminated.

As small grain harvest moves along, some farmers will plant cover crops into those fields to do things such as improve soil condition, control weeds or provide fall grazing for livestock and wildlife. Before planting the cover crop seeds, South Dakota Department of Agriculture Plant Industry Program Manager Brenda Sievers reminds farmers to check the source of the seeds and to be sure a lab analysis has been done on them.

Joe Ikley, assistant professor and Extension Specialist with North Dakota State University discusses using cover crops for weed suppression. Find out why the timing of seeding cover crops matters, which cover crop species are best for helping control weeds, and how geography influences cover crop species selection and weed suppression.

A carefully crafted cover crop composition, manure management, precision agriculture and the right mix of soil additives can be a recipe for improved soil health. Cover crops require a thoughtful approach. Read more in this article from Lancaster Farming.

The middle to end of September is a good time to establish cover crops by broadcasting seeds into corn or soybean before harvest. Broadcast interseeding before harvest allows cover crops to capture more sunshine, growing degree days and rainfall than drilling after harvest.

How are you going to terminate the cover crop if it produces too much biomass? What timing will you use to terminate? Read more in this article from AgWeek.

Cover crops planted in late spring/early summer can help with nitrogen production and weed suppression. In this video from University of Arkansas Extension, find out which cover crop species are best suited for spring/summer planting.

Tong Wang, Advanced Production Specialist with South Dakota State University Extension, shares results from a study that looked at how growers in the Northern Great Plains adopt soil health practices. The study examined how growers value yield and profitability compared to soil health.
