Abstract
A method of fertilizing a plant including applying a composition to a root of the plant. The composition includes a spinel ferrite with a formula of MnxZnyFe2O4, where x+y=1. Particles of the spinel ferrite are spherical and have an average diameter of 10-20 nm. The plant has at least a 40% increase in leaf size compared to a plant under the same conditions but without applying the composition.
Claims9
A method of fertilizing growing a pumpkin plant, comprising:
- contacting the root system of a cultivated pumpkin plant, with an aqueous composition comprising:
- from 100 mg L−1 to 200 mg L−1 of a spinel ferrite
- having a cubic crystal system and in the form of spherical particles of Mn0.5Zn0.5Fe2O4 having an average diameter of from 10 nm to 20 nm;
- wherein the contacting comprises submerging at least partially the root system of the plant in the aqueous composition for a period of from 10 to 20 days.
