Getting it together | Plants, soils and fertilizers
1985
Elsner, John Earl
Abstract: This manual covers four areas basic to agronomy: soils and fertilizers, seeds, weeds, and crop production. The section on soils and fertilizers covers the physical make up of soil. Activities include having soil tests run on top soil, sub soil, and sand to compare their mineral content and testing these soils' water capacity. The last section on soil covers soil conservation concerns and activities. The section on seeds covers seed parts and the germination principle, keeping a list of everything you eat and determining whether it is indirectly or directly from a seed, and germinating seeds under varying conditions and stresses. The section on weeds addresses classification of plants as weeds, and information on herbicide use and safety. On the subject of crop production much emphasis is given to why certain crops fare well in Georgia and others do not. Also included is an exercise comparing different varieties of corn and their performance.
