    Nutrient management for fruit and vegetable crop production: Using manure and compost as nutrient sources for vegetable crops
    (2005) Rosen, Carl J.; Bierman, Peter M.
    Manure and compost not only supply many nutrients for crop production, but they are also valuable sources of organic matter. Increasing soil organic matter improves soil structure, increases the water-holding capacity of coarse-textured sandy soils, improves drainage in fine-textured clay soils, provides a source of slow release nutrients, reduces wind and water erosion, and promotes growth of earthworms and other beneficial soil organisms. Most vegetable crops return small amounts of crop residue to the soil, so manure, compost, and other organic amendments help maintain soil organic matter levels. This discussion addresses differences between the composition of fresh and composted manure, nutrient availability from manure and compost, and calculation of how much manure or compost to apply. Although focused on manure or composted manure, much of the discussion and the methods for calculating rates are generally applicable to effective use of different types of compost, biosolids, and similar organic nutrient sources.

    Soil Test Interpretations and Fertilizer Management for Lawns, Turf, Gardens, and Landscape Plants
    (St. Paul, MN: University of Minnesota Extension Service, 2008) Rosen, Carl J.; Bierman, Peter M.; Eliason, Roger
    Fertilizer recommendations are based on the kinds of plants that are grown, the type of soil they are growing in, and the results of soil tests. Soil testing provides information on the availability of nutrients in the soil and is required for accurate fertilizer and lime recommendations. This bulletin presents current fertilizer and lime recommendations for home lawns, vegetable and flower gardens, small fruits, tree fruits, and ornamental trees and shrubs. Basic recommendations for home lawns are also generally applicable to other turfgrass areas such as golf courses, athletic fields, parks, cemeteries, schools, industrial grounds, and commercial sod farms. Commercial nursery or greenhouse growers interested in fertilizer recommendations for container grown crops should use different soil tests.
