  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. 100% 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."

  3. 70% Agronomy Facts 38B: A nutrient management approach for Pennsylvania: Plant nutrient stocks and flows
    Source: Department of Crop and Soil Sciences Publications

    "Almost all decision-making in agriculture, in the boardrooms of industry or on the tractor seats of farms, affects the distribution of materials such as crops and manure within farms, and the movement of materials such as feeds and farm products to and from farms. Most common farm materials contain important plant nutrients, such as nitrogen, phosphorus, and potassium, and are moved as part of the everyday activities of farming and agriculture. As a result, the many factors considered in each management decision affect plant nutrient distribution and have implications for nutrient management to meet the many expectations."

    "There is the possibility to improve the whole farm nutrient balance and the public's perception of farming."

  5. 67% Pennsylvania Farm-A-Syst: Program Brochure [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "The Pennsylvania Farm Evaluation Program (Pennsylvania Farm?A?Syst) is a voluntary farm evaluation that can be used to confirm that a farm is being managed in an environmentally sensitive way. Pennsylvania Farm?A?Syst also promotes an awareness of existing site conditions or management practices that threaten the quality of groundwater and surface water."

  6. 67% 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. 67% 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. 67% 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."

    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. 62% Environmental Soil Issues: Land Application of Sewage Sludge in Pennsylvania - Use of Biosolids in Crop Production [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Approximately 300,000 tons (on a dry-weight basis) of municipal sewage sludge are produced each year in Pennsylvania. Three viable options now exist for disposal or use of this sludge: landfill placement; incineration; and recycling through application to farm, forest, or mine land. Although each of these options has its place, recycling efforts have increased in recent years because of growing recognition that our society cannot afford to throw away the valuable resources in sewage sludge. Before sewage sludges can be applied to farmland, however, they must be treated further to stabilize organic material and significantly reduce pathogens. Sewage sludges that have undergone such treatment and that are of sufficiently high quality to be used as an agricultural soil amendment ("land applied") under the current regulations are known as ."
