摘要:

Corn (Zea maysL.) and soybean (Glycine max(L.) Merr.) rapid tissue test data for N, P, K, Mg, and Mn were obtained at two locations from experimental plots receiving varying rates and combinations of N, P, and K. Soil test, plant composition, and yield data for each plot were also obtained. Relatively precise tissue test readings were obtained by using color standard sheets. A simple correlation matrix was used to relate specific pairs of variables for corn and soybean data at both locations.
