Planting date studies conducted on UNL's East Campus showed yield decreases of 1/4 bu/ac (2003) and 5/8 bu/ac (2004) for each day after May 1 that soybean were planted.
The benefits of planting soybean near May 1 are well documented. Now, what are the next steps growers can take to further expand on these benefits? Are different maturity groups warranted? What groups are typically being used in irrigated and rainfed environments in Nebraska?

Understanding how the three types of nitrogen stabilizers work can be helpful in deciding whether to add one to your spring application. Short- and long-term studies in Nebraska offer insight into how they performed across multiple years. Now, if you only knew how many inches of rain you'd get the first six weeks after application.
Wheat Production

With the predicted return to more normal temperatures, it's time to get into wheat fields and start scouting. Stripe rust has already been reported in southeastern Kansas and is expected to move northward. Included is a table of fungicide efficacy ratings for disease management in wheat.
Finding a good time for burndown herbicide applications has been a little tricky this spring, given the below-normal temperatures the first half of April and intermittent snow and rain, all of which can decrease herbicide efficacy. Checking the forecast can help identify an optimal window for application.
This week a CropWatch reader asked: Can you safely graze cover crop rye this spring after anhydrous has been applied? That depends on several factors, write three extension specialists in agronomy and beef production.

Should the cold spring delay cover crop termination? Growers walk a fine line between growing cover crops long enough to get the biomass they want without reducing yield in the following grain crop. This discussion from an agronomist, entomologist and weed scientist looks at various factors to consider.
Pesticide Safety
2018 map of agricultural pesticide container recylcing sites
After applying ag chemicals to your field, rinse and recycle the plastic containers at one of 18 sites across the state. This is the 27th year for the Nebraska program, which in 2017 collected 89,000 pounds of containers.
Properly rinsing and recycling pesticide containers saves money, protects you and the environment, and meets federal and state regulations for pesticide use. Here's how to safely prep your containers for recycling.

Wheat condition was rated 12% excellent, 43% good, 38% fair, 6% poor, and 1% very poor in Monday's USDA crop condition report. It included corn planting, at 1%, for the first time in 2018.
The University of Nebraska–Lincoln has joined 15 other public and private universities in FedByScience, an effort to boost federal investment in agricultural research. The effort tells stories in which scientific discoveries and innovations have improved the way food is produced and distributed.

If you walk into a negotiation pushing only your agenda and looking for your "Yes," you may miss out on crucial details and not end up where you think you should be. Getting to a well understood "Yes" is critical to good negotiations.
