Soil phosphorous: 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.

本实验于A、B、C、D四块围栏划定的田间区域内开展，旨在探明各类营养元素对植被的影响。实验共设置8种不同营养元素与1组对照组，所涉营养元素分别为氮（N）、磷（P）、钾（K）、钙（Ca）、镁（Mg）、钠（Na）、水（H₂O）以及微量金属复合剂。每个田间区域内设置36个样地，对应9种处理水平的4次重复。样地规格为1米×4米，以4行9列的网格形式布设，该网格被划分为4个区组，各处理采用随机区组设计完成分配。
