Nitrogen Deficiency/Oversupply. Gypsum is the least recommended remedy. These plants are known to “fix” nitrogen from the air into their roots, bringing the element back into the soil. Yellowing of the younger upper leaves is more pronounced with sulfur deficiency than with nitrogen deficiency because sulfur is not easily translocated in the plant. Newer, high-yield crops, created by the advent of genetic modification or hybridization, extract more sulfur than heirloom or open-pollinated varieties of the same crop. Soils which contain lots of iron (Fe) oxides and sandy soil both have tendencies to have sulfur deficiencies. An abundance of phosphorous in soil can displace the available sulfur, contributing to sulfur deficiency. Magnesium deficiency : F1. In magnesium, the yellowing happens on the lower, older leaves. These processes are highly dependent on the conditions of the soil and work best in warm, moist soils.
