4. 100 pound Sulfur and potash fertilization test
100 pound Sulfur and potash fertilization test
Description
Plot on left fertilized with muriate of potash and plot on right with sulfate of potash. The same amount of potash was supplied to the two plots. The muriate of potash contained no sulfur, while the sulfate of potash supplied sulfur at the rate of 100 pounds to the acre. Note the poor yield and light color on the muriate-of-potash plot and the heavy yield and dark color on the sulfate-of-potash plot.
5. 100 pound sulfur and nitrogen fertilization test
100 pound sulfur and nitrogen fertilization test
Description
Plot on left fertilized with nitrate of soda and plot on right with sulfate of ammonia. The two plots received exactly the same amount of nitrogen. The sulfate of ammonia also supplied sulfur at the rate of 100 pounds to the acre. Note the remarkable influence of the sulfur in the sulfate of ammonia. Antelope Adobe soil.
