Salt

Categories: 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.
