Making Smart Soybean Replanting Decisions

— Written By

Making the decision to replant soybeans can be a challenge. Knowing the facts about your existing soybean stand and its yield potential can help you decide what to do. In this short video learn tips from NC State Extension Soybean Specialist, Dr. Rachel Vann, that you can use to make a smart decision on whether or not to replant.

Here are 4 things to consider when making your decision:

1) Stand Counts
Get an accurate estimate of your remaining soybean stand. You can do this by using one of the following methods recommended by the NC Soybean Producers Association:

Evaluating Plant Stands

2) Yield Potential
Once you have an estimate of what your stand is, compare that to what population you can get 100% of your maximum yield potential. Our data says the following plant populations can still lead to 100% yield potential in North Carolina:
May planted soybeans at 75,000 plants per acre;
June planted soybeans at 90,000 plants per acre;
July planted soybeans at 100,000 plants per acre.

Soybean yields can overcome low plant populations.

3) Problem Solving
Correct the reasons for the poor stand before you replant. Replanting will only be beneficial if the poor stand was a result of an issue that was corrected beforehand. Contact your County Agent for confirmation of the issue and for resources you can use to prevent it from recurring.

4) Net Gains
Replant coverage can certainly benefit your operation. Remember to weigh the economic benefit against the additional time it would take to replant your soybeans. Also, delayed soybean planting dates past mid-June in North Carolina can result in a 1/2 bushel per acre, per day yield disadvantage.

Replanting is a big decision and NC State Extension is here for you! Give us a call to discuss options that will work best on your own farm.
