Book Description
Excerpt from The Comparative Agricultural Value of Insoluble Mineral Phosphates of Aluminum, Iron, and Calcium Phosphorus is the only element that must be purchased and returned to the most common soils of the United States. Phosphorus is the key to per manent agriculture on these lands. This statement Of C. G.-hopkins emphasizes the extreme importance of the phosphorus problem in modern agriculture; especially at the present time when the seriousness of the world food situation is making an urgent appeal to agriculturists to increase and to maintain permanently the fertility of all tillable soils. The acute shortage of transportation facilities has placed farmers, not conveniently situated near phosphate-producing centres, at a disadvantage with regard to procuring phosphorus at other than exorbitant prices. This has resulted in a world-wide prospecting for phosphate deposits and has caused considerable speculation as to the feasibility of utilizing iron and aluminum phosphates for agricultural purposes.
