  3. Conservation Tillage Series: Cover Crops for Conservation Tillage Systems [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Producers seed cover crops to provide a soil cover or barrier against soil erosion. In addition, cover crops can improve the soil by adding organic matter, nutrients, and stability and by acting as scavengers to trap leftover nutrients that otherwise might leach out. Cover crops are used as ground cover, mulches, green manure, nurse crops, smother crops, and forage and food for animals or humans. Cover crops can be annual or perennial species, including certain legumes, grasses, and non-leguminous dicots."

  4. Conservation Tillage Series: Crop Rotations and Conservation Tillage [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Crop rotations increase crop yields by improving soil conditions and reducing weed and insect populations. Rotations also help producers use conservation tillage successfully. A well-planned crop-rotation system can help producers avoid many of the problems associated with conservation tillage, such as increased soil compaction, perennial weeds, plant diseases, and slow early season growth. This publication reviews the effects of crop rotations on conservation-tillage crop production and provides examples of successful rotations used by crop producers in Pennsylvania."

  5. Conservation Tillage Series: Economics of Conservation Tillage [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "There are many potential economic advantages for reducing the number of tillage operations for crop enterprises. These include: 1) lower fuel costs due to fewer trips over the field, 2) reducing the amount of tillage equipment needed, which results in lower machinery investment, 3) lower labor requirements, which reduce hired labor costs or free up operator time for other farm operations, 4) reducing soil loss from water and wind erosion, and 5) conserving soil moisture."
