Responders reported a steady increase in the number of acres they have planted to cover crops over the past five years. They said the most important benefits of cover crops include: improved soil health, reduced erosion and compaction and increased soil organic matter. Other key benefits of using cover crops include: weed and insect control, provides a nitrogen source, attracts pollinators and provides deep taproots.

In the 2015-2016 survey, SARE and CTIC sought data on how farmers manage their fertilizer inputs as a result of their cover crop practices. Cover crop users were asked to indicate their level of agreement with a series of fertilizer-related statements, using a scale ranging from 1 (strongly agree) to 5 (strongly disagree). The statement that got the highest level of agreement was, “Using cover crops has enabled me to reduce application of nitrogen on my cash crop,” with 134 of 1,012 respondents strongly agreeing and 244 checking “agree.” The statement that had the highest level of disagreement was “Using cover crops has required me to use additional crop fertility inputs over time to meet the needs of my cash crop.” Continue Reading →
