On March 15, the U.S. Environmental Protection Agency (EPA) approved the label amendments that further restrict the use of over-the-top dicamba in Iowa and Minnesota. These changes came after the reports of high numbers of off-target dicamba injury incidents in Iowa and Minnesota in 2021. During...

Frost seeding is the easiest and least expensive method for adding new legumes to a pasture. And now is the perfect time to be doing frost seeding.

The goal of frost seeding is to seed while the soil is frozen (usually first then in the morning) and get the seed in contact with bare soil...
