Recovering Flooded Pastures March 29, 2019
Flooded pastures are a mess. After water recedes, follow these steps to help recover your pasture's viability.
First, be safe. Who knows what might have been left behind. Then, before doing any recovery efforts, contact your local Farm Service Agency (FSA) and Natural Resources Conservation Service (NRCS) office to discuss your situation and any assistance they may be able to offer. Do this first! You might be ineligible for assistance if you do work before receiving authorization.
After water recedes and soils firm up, remove debris and repair fences and water sources. Be sure to have water sources tested for nitrates and contaminants. Especially test any surface water like ponds or remaining standing water from the flood.
Next, evaluate sediment levels. Pasture plants may have a tough time emerging through any
more than two or three inches of sediment. Expect poor stands any place where there are thick
deposits. If possible, remove thick deposits.
Erosion may not be a big problem in many areas. However, make any repairs or apply other
erosion control measures as needed. Also, check for any chemical contamination. While it’s unlikely due to dilution by all the flood water, specific sites may be affected, especially if chemical containers were part of the debris.
Don’t even consider grazing until all the previous steps have been taken. Once pastures dry out, allow plants extra time and growth before initiating grazing. And when animals do graze, be sure to leave taller stubble than usual to both keep plants healthy and to minimize animal consumption of any flood contaminants remaining on surface soil.
