We have compared the manurial effects of magnesian fertilizers for barley plants on magnesium-deficient soils. We have learned that magnesium functioned as a carrier of phosphate and was very effective for the grain productivity of barley plants. And again we have ascertained that fused phosphate and magnesian limestone were very effective to eliminate magnesium deficiencies in barley plants and their manurial effects were remarkably excellent on these soils.
