CHELATES OF 1,2-DIAMINOCYCLOHEXANE TETRAKIS(METHYLENE PHOSPHONIC ACID)USEFUL FOR SUPPLYING NUTRIENT METALS TO PLANTS GROWING IN CALCAREOUS SOIL

摘要

Iron, manganese and other essential nutrient metals are supplied to plants growing in calcareous soils by treating the soil with a metal chelating agent or by treating the plant and/or the soil with a metal chelate of said chelating agent, said chelating agent being a 1,2- diaminocyclohexane tetrakis(methylene phosphonic acid) compound.
