Nitrate management in tile water is a big reason why this water control structure has slowly gained a foothold in the Corn Belt, but its potential for providing timely water to corn and soybeans may spell the future for this underground tile water management tool....More
The full extent of damage from flooding and saturated soils cannot be seen until the corn plant has a chance to recover. Knowing what factors affect damage and survivability, and what signs to look for when assessing plant health will help you make the best decision for the long term success of your corn crop....More
