Experiment 003 - Effects of Various Nutrients and Water on Vegetation

This experiment was conducted within the fenced areas of fields A, B, C, and D. The purpose of this experiment was to determine the effect of various nutrients on vegetation. There were eight different nutrients and a control. The different nutrients were N, P, K, Ca, Mg, Na, H2O, and a combination of trace metals. There were 36 plots in each field, 4 replicates of the 9 treatment levels. The plots were 1 meter by 4 meters and were laid out in a 4 by 9 grid. The grid was divided into 4 quarters and treatments were assigned with a randomized block design.
