COMMERCIAL SOURCES OF PLANT-FOOD
Salt is not a direct fertilizer, and its use is not to be
advised unless it can be secured at a very low price per ton. Some
soils have been made more productive by the application of 200 to 300
pounds per acre, and chiefly in case the salt was mixed well with the
soil when the seed-bed was made. The practice of using salt as a
top-dressing on wheat in the spring gives less effectiveness it is
believed. Salt frees potash in the soil, and may have some practical
effect upon soil moisture. As a soil amendment, salt has had more
reputation than its performance justifies. If land is infertile, it is
better, as a rule, to apply actual plant-food.
