A fall-planted cereal rye cover crop can have both positive and negative impacts, for example by tying up nitrogen, reducing soil moisture prior to planting, increasing insect pressure, reducing weed pressure, reducing soil erosion and allelopathy. The spring rains in 2021 and warming soil temperatures are encouraging cereal rye and wheat cover crops to take off. Read more in this article from University of Nebraska Extension.
Cover crops can serve as a useful tool of an integrated weed management program. Research at the University of Nebraska has shown that cover crops such as cereal rye can provide good control of winter annual weeds and other troublesome species like horseweed, and also provide early-season suppression of summer annual weeds like waterhemp.
A common question when incorporating cover crops into a production system is, will the cover crop interfere with the performance of residual herbicides included with the burndown treatment? This article from the University of Nebraska will discuss the fate of residual herbicides applied to crop residue and living cover crops, and how this may influence herbicide effectiveness.
In both wet spring weather and drought conditions, the timing of cover crop termination can have a big impact on soil moisture levels, according to Purdue University.
Data from the 2nd annual Cover Crop Benchmark Study — compiled and organized by Cover Crop Strategies — shows a proposed rule change to NRCS conservation technical standards relating to cover crops could have a very negative affect on farmers and ranchers.
In this video, Dr. Michael Flessner with Virginia Tech University Extension discusses why growers should have a termination plan before even seeding covers, termination methods for popular cover crop species, which cover crop species are difficult to terminate, and more.
Cover crops have been a great tool for many producers across Nebraska as they can be used for managing soil erosion, weeds, moisture accumulation, microbial activity and forage crops for livestock producers. Every producer has different goals while planting their cover crop, the same message rings true for termination. Read more in this article from the Grand Island Independent.
Current cool temperatures increase the risk of failures in terminating cover crops. While cereal rye continues to grow during these conditions, activity of herbicides is reduced, says Iowa State University Extension.
An adjustment of conservation standards by the NRCS could prohibit growers from mechanically harvesting cover crops for seed, hay, silage or biomass, potentially hamstringing dairies who rely on covers for additional or emergency forage.
The spring rains and warmer soil temperatures are allowing rye and wheat cover and grain crops to really take off. Questions about termination occur as farmers consider the cost of the cover crop, their goals, and gaining more biomass growth for their investment.

Earlier this week we paid another visit to this year’s Conservation Ag Operator Fellow, Ray McCormick in Vincennes, Ind., and one thing about Ray is that even when it’s the “off season,” he’s still thinking ahead for next season.
