The coatings of the invention provide potassium in a readily available form in combination with other nutrients that promote early plant growth and health. The potassium-based fertilizer product which comprises: potassium, zinc, manganese and iron. Calcium may also be added. The mixture is applied in a 325 MESH or finer powder to suitable agronomic carriers.

Potassium-based starter fertilizer

A fertilizer product for delivering starter fertilizer to crops in soils as an alternative to traditional phosphorus applications to enhance rapid early plant development. Specifically, the fertilizer product comprises a synergistic mixture of:

Phosphate magnesium zinc fertilizer

A starter fertilizer product combining manganese with P and Zn creates a previously unknown synergy in early plant growth and plant health.

Phosphorus zinc manganese fertilizer

The uptake of foliar-applied metal ion nutrients, for example, zinc, iron, magnesium and copper, is influenced by humidity. Specifically, uptake is negatively impacted if the zinc is applied under low humidity, as the metal ion is 'locked up' by leaf waxes as the droplet dries on the surface of the leaf, thereby rendering the metal ion useless. Described herein is a foliar metal ion fertilizer comprising (a) a metal ion sulphate in combination with a mixture of (b) urea and (c) a substance with a suitable point of deliquescence (POD) such as organic surfactants, calcium chloride, magnesium chloride or combinations thereof.

Foliar metal ion nutrient fertilizer

A high efficiency magnesium fertilizer and a method for applying the same to an agronomic carrier or directly to soil. The magnesium fertilizer product is a powder comprising two or more forms of magnesium mixed with a suitable formulating agent.

High efficiency magnesium fertilizer

The efficiency of applied phosphorus can be improved by applying phosphorus as a coating onto plant growth (roots and shoots) or by applying phosphorus as a coating on prills or granules of other forms of fertilizers. The composition comprises (a) monoammonium phosphate, (b) struvite and (c) magnesium sulphate. The first two ingredients ensure that there is a source of rapidly available phosphorus (MAP) and a source of more slowly available phosphorus (STRUV). The third ingredient is to provide a source of sulphate which will, in the area surrounding the coated product following application thereof to the soil, act to stop ambient calcium from reacting with the phosphate thereby rendering it inactive.

High bioavailability phosphorus

An agronomic carrier coated with an acidifying agent and a method for preparing same is described.
