Transcript: Soil Conservation
Cover crops, crop rotation, and other soil conservation practices are gaining in popularity with Iowa farmers, according to a recent report.
This is the Iowa Environmental Focus.
The international consulting firm Datu Research released the 53-page report in December which found that 23 percent of those surveyed reported that they planted cover crops on their farms. Eighty percent of respondents said they alternate their fields between corn and soybeans each year while 70 percent of farmers said they practice minimum or conservation tilling practices.
These techniques improve soil health and help to regulate moisture content. This allows soil to retain more nitrate and phosphorus, saving farmers on fertilizer costs while also reducing nutrient runoff which is a major cause of water pollution in Iowa.
Agricultural runoff accounts for approximately 70 percent of the nitrogen and phosphorus that enters the Gulf of Mexico through the Mississippi River.
