  1. 100% Agronomy Facts 64: Weed Management in Organic Cropping Systems
    Source: Department of Crop and Soil Sciences Publications

    "When managing weeds in organic systems, producers use many of the same techniques used in conventional systems, but they rely much more on nonchemical control strategies. The primary weed control strategies for organic systems are cultural and mechanical, focusing on prevention, crop rotation, crop competition, and cultivation."

  2. 74% Growing Turf Under Shaded Conditions
    Source: Department of Crop and Soil Sciences Publications

    "The establishment and management of quality turfgrass under shaded conditions often is possible if the basic requirements for turfgrass growth are known and understood. Trees have extensive root systems (often quite shallow) that enable them to utilize huge amounts of water and nutrients, and they have dense leaves that severely restrict the light intensity under the trees. These three factors - competition for water, nutrients, and light - are the basic causes of turfgrass failure under shaded conditions. Poor drainage also contributes to poor turfgrass development in shaded areas. Poorly drained shaded areas often become infested with moss, which provides additional turfgrass competition."

  3. 70% Environmental Soil Issues: Land Application of Sewage Sludge in Pennsylvania - Biosolids Quality [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Treatment of municipal wastewater produces sewage sludge, a dilute suspension of solids in water. Sewage sludge contains significant amounts of essential plant nutrients and organic matter that can benefit crop production. Application of sewage sludge to farmland has been a common practice in Pennsylvania for many years and allows this material to be recycled, rather than incinerated or disposed of in landfills. In addition to its beneficial aspects, however, sewage sludge also contains trace elements, organic chemicals, and pathogens that could harm humans or the environment if they are not properly treated and managed."

  5. 59% Prevention and control of foot problems in dairy cows [pdf]Get Acrobat Reader
    Source: Penn State - Dairy and Animal Science Publications

    "Joint publication with Veterinary Science. Covers types of foot problems, bovine hoof, laminitis, digital dermatitis, hoof-care treatment, and preventive management.

  6. 46% Pennsylvania Farm-A-Syst: Worksheet 5: Milkhouse Waste Management [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Milking center wastewater usually is considered a dairy sanitation problem. If not carefully managed, however, dairy wastewater can contaminate surface water or groundwater. Milkhouse wastewater may contain paper towels, detergent, milk solids, fats, manure, and other organic materials that reduce oxygen levels in water as they decompose. Fish and other aquatic life need this oxygen to live. If milk is frequently poured down the milkhouse drain, milk fats can cause premature aging of a wastewater septic system due to clogging of the drain field."

  7. 46% Conservation Tillage Series: Soil Compaction and Conservation Tillage [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Soil is a complex medium, but for simplicity we can think of it as a combination of solid mineral and organic particles and pore space. Pore space allows for air and water storage and movement in soils. Compaction squeezes the soil and, since solids do not compress, pore space is reduced. A footprint or wheel track rut in a field, for example, signals compaction."

  8. 46% 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."

  9. 46% Agronomy Series #146: Radiocarbon Data for Pennsylvania Soils [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Radiocarbon dating of material has given scientists a major tool to determine the age of materials that have incorporated carbon from the atmosphere into various organic as well as inorganic forms."

  10. 38% Horse Facilities 1: Horse Stall Design [pdf]Get Acrobat Reader
    Source: Penn State - Dairy and Animal Science Publications

    "The stall is the basic functional unit of a horse stable or shelter. A simple backyard pleasure horse stall may at first appear different than a stall in a full-feature boarding operation, but they both provide a suitable environment for the horse and handler. Safety for handlers and horses should be a primary consideration in stall design. Comfort for the horse is very important, as is convenience for the handler in performing chores associated with good horse care. This six-page publication provides an overview of some basic stall features for a typical 1,000-pound horse. "
