Methods of research in pasture investigations
1929
Schuster, G.L.
There are many variable factors at work in pasture investigations, such as animals, soil, climate, grass population, etc. In order to reduce the error of random sampling, replications are necessary. The author hesitates to make any recommendations as to the number of replications that should be made because of the costs involved in such an extensive project. A project designed to obtain the basic results, i.e., animal weights, milk flow, or increased growth of meadow, should have four replications of plats with several control or check plats, and each plat should carry three animals. Other supporting and explanatory data, such as duration of grass, chemical analysis, etc., should be obtained under the conditions of the main project and at the same time.
