Description
The theories of soil formation and plant growth are explained in a general way, and shown that under prolonged cultivation the soil is exhausted in respect of three of its most important foods - phosphorus, nitrogen, and potassium. The point is stressed that the best progress in the field of fertilizer will come through a true coordination of its various parts, both among themselves and together in respect to other industries, as the result of enlightened cooperation between the fertilzer industry, the Government and the people.
