Abstract: 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.

Abstract: A pneumatic conveyor is operable to convey fine material and includes a pressure vessel and a pneumatic injection port. The pressure vessel presents a chamber operable to receive fine material and to be selectively pressurized with air to pressurize and convey the fine material. The pressure vessel includes an inclined wall that extends upwardly relative to an outlet, with fine material in the chamber being collected by the inclined wall and urged toward the outlet. The injection port fluidly communicates with the chamber, with the injection port located adjacent the outlet to inject compressed air into the flow of pressurized fine material.

Abstract: A method for electrostatically adhering an agricultural input powder to an agronomic carrier is described. A dry nutrient powder is electrostatically charged in a charging chamber which has a grounded metal component such that the electrostatically charged powder moves towards the metal component. The agronomic carrier is then passed by the charged powder such that the charged powder adheres to the carrier.

Abstract: 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: from about 0.5 to about 1 part Mg: from about 2.4 to about 2.8 parts P2O5: from about 1.4 to about 2.8 parts Zn.

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

Abstract: 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.

Abstract: 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.
