  1. Conservation Tillage Series: Nutrient Management in Conservation Tillage Systems [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "To understand soil fertility and nutrient management in conservation tillage systems, we need to recognize the unique conditions in these systems that influence nutrient behavior and management. One of the most important functions of conservation tillage systems is the maintenance of crop residues on the soil surface to protect the soil from erosion."

  2. 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."

  3. Considerations in Managing Cutting Height of Corn Silage
    Source: Penn State - Dairy and Animal Science Publications

    "Recently, interest has developed in cutting corn silage higher during harvest to improve the forage quality. Cutting corn silage higher can increase silage quality because the lower part of the crop is poorly digestible, but this can also reduce yield."

    "Contract manure hauling offers several opportunities to producers."

  5. Control of Summer Annual Grass Weeds
    Source: Department of Crop and Soil Sciences Publications

    "Summer annual grasses continue to be pervasive weed problems in many turfgrass areas throughout Pennsylvania. The most common summer annual grasses in turf include crabgrasses ( spp.), goosegrass (), foxtails ( spp.), and barnyardgrass (). Satisfactory control of these weeds can be obtained by cultural and chemical methods, provided the life cycle of the plant is understood."
