Soil Conservation Yields Economic Gains

Soil conservation practices such as growing cover crops and going no-till can result in an economic return of over $100 per acre, according to a set of case studies jointly released by the National Association of Conservation Districts and Datu Research, LLC.

Cover crops, like tillage radish, can improve soil health and structure.

Cover crops and no-till can limit soil loss, reduce run-off, enhance biodiversity and provide other benefits. Naturally, farmers who are considering adopting these soil conservation practices are keen to know how they will affect their farm’s bottom line.

“These case studies quantify for producers, policy-makers and researchers alike what the economic advantages of using no-till and cover crops are, and why it makes good sense for farmers to try them and for organizations like NACD to support and even incentivize their use,” said Jeremy Peters, NACD CEO. “We have loads of anecdotal data that says conservation practices benefit the land and producers’ pocketbooks, but now we have run the numbers and know how much.”

During the three-year study period, corn-soybean farmers experimented with cover crops and/or no-till, and quantified the year-by-year changes in income they attributed to these practices compared to a pre-adoption baseline. They found that while planting costs increased by up to $38 per acre: Fertilizer costs decreased by up to $50 per acre; erosion repair costs decreased by up to $16 per acre; and yields increased by up to $76 per acre.

The studies also found that with adoption of these soil conservation practices, net farm income increased by up to $110 per acre. Included in the farmers’ calculations was the considerable time they spent attending workshops or searching the internet to learn about no-till or cover crop practices.

“That time turns out to be an excellent investment, when bottom lines start improving,” said Marcy Lowe, CEO of Datu Research, which conducted the case studies in partnership with NACD. “Farmers who switch to these practices can see losses at first. But thanks to these case study farmers who are generously sharing what they’ve learned, that learning curve will speed up for other farmers.” Continue Reading →

Cover Crops on the Farm

Cover crops are increasingly being used by farmers across the country to suppress weeds, conserve soil, protect water quality and control pests and diseases.

The fourth annual SARE/CTIC Cover Crop Survey collected data from more than 2,000 growers from 48 states and the District of Columbia. The survey provides insight into cover crop usage and benefits and explores what motivates farmers to include cover crops in their farm management and soil health plans.

Respondents reported a steady increase in the number of acres they have cover cropped 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 reported key benefits of using covers are weed and insect control, nitrogen fixation, attracting pollinators and providing deep taproots.

North Central SARE (Sustainable Agriculture Research and Education) and CTIC (Conservation Technology Information Center) sought data on how farmers use cover crops to manage their fertilizer inputs. Growers 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.”
