According to the U.S. Department of Agriculture, \u201cthe use of cover crops <\/span><a href=\"https:\/\/www.ers.usda.gov\/webdocs\/publications\/100551\/eib-222.pdf?v=5803\"><span style=\"font-weight: 400;\">increased by 50 percent between 2012 and 2017<\/span><\/a><span style=\"font-weight: 400;\">.\u201d Federal and state incentives are helping farmers fund these efforts at increasing rates, although they still comprise only a small percentage of the country\u2019s cropland.\u00a0\u00a0<\/span><\/p>\n<h2><b>What are cover crops?<\/b><\/h2>\n<p><a href=\"https:\/\/modernfarmer.com\/2015\/08\/how-to-grow-a-cover-crop-this-fall\/\"><span style=\"font-weight: 400;\">Cover crops<\/span><\/a><span style=\"font-weight: 400;\"> refer to vegetation planted in empty fields\u2014<\/span><i><span style=\"font-weight: 400;\">covering<\/span><\/i><span style=\"font-weight: 400;\"> the soil, get it?\u2014at the end of growing seasons to enrich the ground and minimize erosion. They can also be added to crop rotations to improve soil health in fields that have been degraded from growing the same thing year after year. Cover cropping is a means of increasing soil fertility without chemicals.<\/span><\/p>\n<h2><b>How do cover crops work?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">All cash crops (what farmers grow to sell) pull nutrients out of the soil as they mature. It\u2019s important to replenish those nourishing substances after every harvest so future crops can also flourish. With cover cropping, farmers plant specific varieties that have the ability to pull nutrients such as nitrogen or phosphorus from the atmosphere and return them to the soil so future plants can absorb them. The cover crops are not harvested but instead tilled back into the ground, where they release these beneficial elements as they decompose.\u00a0<\/span><\/p>\n<h2><b>What plants make good cover crops?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Farmers have numerous options when it comes to cover crops, which primarily stem from the legume and grass families. Plants such as rye, alfalfa, winter wheat, clovers, radish, oats and mustard can work well depending on the specific goals for a landscape.\u00a0<\/span><\/p>\n<h2><b>What are the benefits of cover cropping?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Beyond its primary function of adding nutrients back into the soil, the practice of cover cropping has other benefits, too, including: suppressing weeds; reducing erosion; controlling pests and diseases while attracting pollinators; increasing soil\u2019s moisture and nutrient content; enhancing biodiversity; and improving future crop yields. These plantings can broadly aid in improving a farm\u2019s resilience, a growing need in the face of climate change. Many of these benefits become apparent within one year of using cover crops.\u00a0<\/span><\/p>\n<h2><b>What are the drawbacks of using cover crops?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Among their <\/span><a href=\"https:\/\/modernfarmer.com\/2022\/07\/cover-crops-future-climate-change\/\"><span style=\"font-weight: 400;\">downsides<\/span><\/a><span style=\"font-weight: 400;\">, cover crops are an additional expense (financial and otherwise) for cash-and labor-strapped farmers. They can also overwinter and compete with cash crops, so it\u2019s critical that farmers carefully choose the appropriate cover crops for their fields.<\/span><\/p>\n<p>What do you want to know about cover crops?
