The educational materials listed on this page are about Conservation Tillage.
Conservation tillage reduces soil disturbance by leaving more than thirty percent of the soil surface covered with the residue of a previous crop. This crop production system improves soil conservation, reduces soil erosion and limits water runoff. Producers can choose from several different conservation tillage systems no-till, strip-till, ridge-till or zone-till—based on their individual cropping system and on the amount of residue they want to leave on the soil surface. There is also a variety of tillage equipment available for farmers and ranchers, depending on which tillage system they use. No-till farming leaves all of the previous crop’s residue on the field. Farmers who use a strip-till system only disturb the section of soil that is necessary for seeding. Strip tillage is similar to zone tillage, but the latter cuts deeper into the soil to increase water infiltration. In ridge-till systems, farmers build raised seed beds to create a warmer seedbed with better drainage. Cover crops can be added to any conservation tillage system to provide additional residue and soil cover between cash crops.

Cover Crops and Biodegradable Mulches for Weed Control
AUBURN, Alabama – High biomass cover crops are effective in controlling weeds in vegetable production, while contributing to higher produce yields, Auburn University researchers have found. In addition, pre-emergence herbicide applications can be eliminated from weed management programs in the presence of heavy residues from cover crop mixtures. Through a Southern Sustainable Agriculture Research and […]
Low-external-input Sustainable Agriculture Provides Environmental Benefits and Economic Gains in Rice Production
STARKVILLE, Mississippi – Rice, for all of its importance as a global food staple, can have a number of environmental tradeoffs. Intensively managed, the crop can put a strain on natural resources, particularly soil and water. But a more sustainable production system may enhance environmental quality at an economic gain for the farmer, based on […]
Texas Farmers Learn to Build Soil Health Through No-till and Cover Crops
VERNON, Texas – It’s a hot, dry, windy summer day on the plains of North Texas, and a group of farmers are standing in the middle of a field to learn how techniques to build soil health benefit their cash crops in Texas’ harsh environmental conditions. “This is what no-till looks like in the first […]
Equipment Demonstration and Conservation Systems Overview
Conservation tillage combined with high residue cover crops (Conservation Systems) can maximize residue production and minimize residue decomposition to promote the increase in organic matter across degraded soils of the Southeast, despite climatic conditions.
Economics of Cover Crops II (Part 2): Benefits of Cover Crops and No-Till Vegetable Production in North Alabama
While the benefits of cover crops are similar regardless of cash crop, there are a number of benefits that are particularly important to vegetable producers. The main benefits of cover crops in vegetable production include increased organic matter; additional N through the use of legumes; suppressing disease, nematodes, and weeds; reducing soil erosion; providing habitat for beneficial insects; and improving soil tilth.
Soil Biology: Cover Crops and Disease Suppression
Cover crops provide several benefits to soil health such as improving soil structure, reducing the need for synthetic chemicals by decreasing weed biomass, increasing soil organic matter, contributing nutrients to the soil, retaining soil moisture, and decreasing soil erosion. In addition, the integration of cover crops into crop production often leads to soils that are suppressive to plant diseases (i.e. have less potential for disease development).
