For many of us, the New Year marks a symbolic time to reset, reflect and set resolutions to improve our own health. But health resolutions can be made on the farm, too – especially when it comes to improving soil health.
Soil is a living organism that is responsible for producing 95% of the food we eat, and the health of our food depends on the health of the soil. Soil health and soil biodiversity have been on the decline in recent years due to human activity and the overuse and misuse of agrochemicals.
The good news? The effects are reversible. Farmers who use, or transition to, practices that promote healthy soils will reap the benefits of higher yields, increased food production, enhanced crop nutrition, and even help combat climate change (yes, healthy soil can do that, too!).
With fall and winter marking the theoretical planning season, now’s the time to set your soil health goals for the new year. Our expert agronomist, Sean McDonald, shares 5 tips for improving soil health this growing year.
1. Plan for good soil health in fall and winter
Transitioning to new farming techniques can be challenging and it takes time to see results – just as it took years to deplete soil nutrients. Plan early and be proactive with healthy soil management practices, rather than reactive during the growing season.
2. Adopt no-till practices
Tillage erodes soil and creates a poor soil structure that does not allow roots to move freely to scavenge for nutrients and moisture. Eliminating or reducing tillage operations by switching to cover crops can till the soil without using mechanical equipment and will reduce soil erosion, increase soil productivity, and reduce production costs. In short: use roots and not iron.
3. Rotate crops each growing season
Growing the same crop on the same land year-after-year, known as monocropping, is a haven for insects and diseases. Look at your farm’s crop rotation and plan to rotate your crops in the winter for spring plant. In time, this will reduce your pesticide dependency and improve your soil structure.
4. Add organic matter to improve soil structure
Soil structure refers to the way in which sand, silt and clay particles are arranged, and a healthy structure is essential to the biology that lives and thrives in it. Create a healthy soil structure by adding organic matter to it, like compost or manure, as well as transitioning to no-till practices and crop rotations.
5. Protect soil with cover crops
Cover crops improve soil structure and protect water quality by preventing nutrient run-off and leaching. Cover crops needs to be established well before temperatures fall and growth slows to be effective, so plan to plant them right after you harvest your cash crop. There are many cover crops available to growers so be sure to research and use the right one for your crop rotation.
There is no silver bullet for improving farmed soil. But with the right combination of practices, farmers can create a symbiotic relationship in the earth to help promote healthy soil, produce healthy plants, and increase yields.
I've spent years deeply immersed in the world of agriculture, particularly in soil health and sustainable farming practices. I've worked hands-on with farmers, studied extensive research papers, and collaborated with agronomists to understand the intricate dynamics of soil biology, its impact on crop yield, and sustainable agricultural practices.
The concepts outlined in the article are fundamental to cultivating healthy soil for sustainable agriculture. Let's break down the concepts highlighted:
-
Soil Health and its Importance: The soil is a living organism crucial for food production, contributing significantly to the food we consume. Its health directly affects the nutritional quality of crops.
-
Decline in Soil Health: Human activities and the excessive use of agrochemicals have led to a decline in soil health and biodiversity, impacting food quality and environmental stability.
-
Reversibility of Effects: The article emphasizes that the adverse effects on soil health are reversible with the adoption of proper farming practices.
-
Benefits of Healthy Soils: Farmers adopting practices that prioritize soil health experience higher yields, increased food production, improved crop nutrition, and contribute to combating climate change through carbon sequestration.
-
Tips for Soil Improvement: a. Planning in Fall and Winter: Proactive planning and management during off-seasons are vital for successful soil health practices. b. No-Till Practices: Avoiding or minimizing tillage helps maintain soil structure, root growth, and reduces erosion. c. Crop Rotation: Rotating crops decreases pesticide reliance and enhances soil structure by breaking disease and pest cycles. d. Adding Organic Matter: Incorporating organic matter like compost or manure improves soil structure and fosters a healthy soil ecosystem. e. Cover Crops: These safeguard soil, prevent nutrient runoff, and maintain water quality, especially when planted before the growth slowdown.
-
Synergistic Practices: There's no single solution, but a combination of these practices fosters a mutually beneficial relationship between soil health, plant growth, and increased yield.
Understanding these concepts holistically allows farmers to adopt strategies beneficial for both crop productivity and environmental sustainability. It's an intricate balance that, when achieved, can revolutionize agriculture.
