The present invention relates to a
crop nutrition composition in the form of
liquid suspension comprising a homogeneous mixture of one or more of
water insoluble Magnesium salt, complex or derivative thereof in the range of 1-70% w / w of the total composition and one or more of
water insoluble Zinc salt, complex or derivative thereof in the range of 1-50% w / w of the total composition and one or more of
water insoluble Iron salt, complex or derivative thereof in the range of 1-50% w / w of the total composition with at least one agrochemically acceptable
excipient; wherein
elemental Iron is present in the range of 0.01% to 40% w / w of the total composition and wherein elemental
Zinc is present in the range of 0.01% to 40% w / w of the total composition and wherein elemental
Magnesium is present in the range of 0.01% to 50% w / w of the total composition and wherein the composition comprises of particles in the size range of 0.1 micron-20 microns. The
liquid suspension composition is in the form of a suspension concentrate, oil dispersion or a suspo-
emulsion. The present invention further relates to a method of treating plants and meeting their nutritional requirement by making essential nutrients like
Magnesium,
Zinc and Iron available to them and also unlocking other micronutrients and trace elements present in the soil which hitherto were not available because of various factors primarily being soil degradation on account of excessive use of synthetic fertilizers. The present invention also relates to strengthening the plants so as to withstand
pest infestation. The present invention also relates to a method of
biofortification of
plant with essential micronutrients.
