  1. Agronomy Facts 21: Red Clover
    Source: Department of Crop and Soil Sciences Publications

    "Red clover ( L.) is grown throughout the northeastern United States for forage and is used in rotations for soil improvement. It is adapted to areas with moderate summer temperatures and adequate moisture throughout the growing season. Unlike alfalfa, red clover will grow moderately well in slightly acid soils. However, maximum yields are obtained when soil pH is 6.0 or higher."

  2. Agronomy Facts 41: Strategies for extending the grazing season [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Several strategies can be employed to supply forage into the fall or early winter and effectively extend the grazing season by 60 to 90 days, thus reducing the need for stored feeds. These strategies can be categorized into two major groups: 1) stockpiling (conserving cool-season forages in late summer for use in the fall and winter), or 2) utilizing forage crops that continue to grow in the fall and early winter."

  3. Agronomy Facts 51: Starter Fertilizer
    Source: Department of Crop and Soil Sciences Publications

    "Starter fertilizer is a small quantity of fertilizer nutrients applied in close proximity to the seed at planting. Starter fertilizers enhance the development of emerging seedlings by supplying essential nutrients in accessible locations near the roots. Rapid crop establishment is desirable since plant development and yield can be influenced during early growth stages. Also, fast-growing young plants generally are more resistant to insect and disease attacks and can compete with weeds more effectively. Readily available nutrients near young plants help ensure rapid early growth and the formation of large leaves, which are necessary for photosynthesis, subsequent growth processes, and earlier crop maturity."

  4. Agronomy Facts 61: Wirestem Muhly Management in Agronomic Crops [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Wirestem muhly is a perennial grass species that can be problematic in conservation tillage production systems throughout Pennsylvania and the Northeast. It is a particular problem in no-till corn and soybean production, but it can also be troublesome in orchards, in nursery and vegetable crops, on roadsides and streambanks, and in other areas with rich, moist soils. It is native to America and can be found in many areas of the midwestern United States from South Dakota to Missouri and eastward to Virginia and Maine."

  5. Pennsylvania Farm-A-Syst: Worksheet 1: Water Well Condition and Construction [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "About 80% of Pennsylvania?s rural residents use groundwater to supply their drinking water and farmstead needs. Wells are designed to provide clean water. If they are not properly constructed or maintained, groundwater may become contaminated with bacteria, nitrates, and pesticides. These contaminants put family and livestock health at risk."

  6. Pennsylvania Farm-A-Syst: Worksheet 10: Animal Waste Land Application Management [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Managing the land application of animal waste to protect water quality depends on applying rates based on crop requirements and soil conditions, knowing the composition of the animal waste, avoiding runoff from recent applications, and protecting the application areas from runoff and soil erosion. Runoff from fields and water leaching through soil can carry plant nutrients, soil, microorganisms, and other potential pollutants from the fields to surface water or groundwater."

  7. Pennsylvania Farm-A-Syst: Worksheet 11: Soil Conservation Management [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Soil conservation protects a valuable resource and reduces the off-farm direct impacts of sediment or the indirect impacts of nutrients or pesticides that may be attached to eroded soil particles. A good soil management program has three goals: to protect the soil from erosion by water or wind; to reduce runoff from the land into surface water; and to maintain or improve soil quality."

  8. The Pennsylvania Phosphorus Index: Version 1 [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Increased attention has been focused on phosphorus (P) management because of water quality concerns resulting from eutrophication. In freshwater systems, elevated P inputs can lead to accelerated eutrophication and degraded water quality. Despite water quality concerns, adequate levels of soil P must be maintained to promote optimal crop production. Therefore, management options for P must be flexible to address agronomic concerns while providing water quality protection."

  9. Agronomy Series #132: Listing of Characterized Soils in Pennsylvania [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "The Pennsylvania State University has been characterizing Pennsylvania soils since 1957. Prior to 1957, soils from three counties (Lancaster in 1955, Chester in 1956, and Erie in 1956) were sampled and characterized by the USDA Soil Conservation Service (SCS). The characterization process entails the excavation of a soil pit, a description of the pedon's (profile) morphology (color, structure, etc.), as well as a description of site characteristics (slope, vegetation, etc.). In addition the soil is sampled horizon by horizon and various laboratory analyses are performed on the collected samples."

  10. Agronomy Series #133: Cambic Horizons in Pennsylvania Soils [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Cambic horizons are subsurface soil layers of pedogenic change without appreciable accumulation of illuvial material (clay, Fe + Al + humus, carbonate or gypsum), and are part of the USDA Natural Resources Conservation Service?s (formerly the USDA Soil Conservation Service) Soil Classification System "Soil Taxonomy"."
