Today’s guest post is by Marty Adkins, Assistant State Conservationist for Iowa Natural Resources Conservation Service (NRCS), a member of the Iowa Learning Farms Steering Committee.
The quality of Iowa’s soils make this a unique place. How we manage Iowa’s agricultural soils affects just about everything else here. From increasing wildlife to improved water quality to sustainable economic development, our future begins with healthy soils.
Wildlife – Over 97% of Iowa’s land is privately owned, and a vast majority is a part of farms. Most Iowa wildlife spends some or all of their lives on farms.
The same practices that are good for Iowa soils – no-till farming, cover crops, buffer strips, diverse native plant seeded areas, waterways, diverse crop rotations, well-managed pastures – are good for wildlife. The practices provide cover, food and travel corridors. They protect water sources on which wildlife depends. Practices that protect and build soils are good for wildlife too.
Water Quality – Water bodies reflect the condition of their watersheds. Eroding fields deliver sediment and nutrients to streams and lakes. Soils protected from erosion keep that soil and associated nutrients in fields where they belong.
Fields protected by cover crops or other vegetation growing throughout the growing season retain nutrients in the root zone that would otherwise find their way into streams or ground water. Practices that protect and build soils are good for water quality
Economic Development – Over one-third of the largest 100 food manufacturers have Iowa operations. These companies are located in Iowa because the commodities they depend on are produced here.
Statistics from 2014 showed that agriculture and related industries contributed $31.6 billion to the Iowa economy and was responsible for 122,764 jobs. They also showed that 37 of Iowa’s counties derived at least one half of their economic output from agriculture and related industries.
The foundation of all of this economic activity, now and into the future, is Iowa’s productive soil.
No matter what issue you care about, you need to be interested in protecting and building Iowa’s soils.
