Farmer Tim Smith stands by a creek that cuts through his property near the north-central Iowa town of Eagle Grove. He does several water quality conservation practices on his land including a bio-reactor, strip tilling and cover crops.
This summer, officials in Iowa have been asking farmers to voluntarily reduce the amount of fertilizer they use. That’s because the fertilizer contains nitrates that are being washed into state waterways and creating environmental concerns locally and nationally. The runoff has been particularly bad this year, and the outcry over typical crop practices is growing.
