Environmentally-Friendly High Potassium-Content Liquid Fertilizer and Uses for the Fertilizer

摘要

The present invention provides a method for using a new liquid fertilizer comprising potassium from a potassium source selected from the group consisting of potassium acetate, potassium formate, potassium citrate, potassium succinate, potassium propionate, potassium phosphate, organic sources of potassium, animal manure, and combinations thereof, and having a slightly alkaline pH and relatively low salt index compared to other sources of potassium for liquid fertilizer products. The fertilizer composition may further comprise additives such as sulfur, zinc, boron, calcium, manganese, iron, copper, cobalt, magnesium, or a combination thereof.

主权项

1. A method for fertilizing an agricultural crop comprising applying a liquid fertilizer composition at a rate of from about 0.25 gallons per acre to about 10 gallons per acre wherein the method of fertilizer composition application is selected from the group consisting of in-furrow application, foliar application, side-dress treatment after planting, pre-planting soil injection, broadcast application, banding 2×2 and fertigation; and, wherein the fertilizer composition consists essentially of:
a. from about 10 wt % to about 27 wt % available potassium in the form of K2O wherein the potassium is derived from a potassium source selected from the group consisting of potassium acetate, potassium formate, potassium citrate, potassium succinate, potassium propionate, potassium phosphate, organic sources of potassium, animal manure, and combinations thereof; b. from about 0 wt % to about 25 wt % secondary nutrient selected from the group consisting of sulfur, zinc, boron, calcium, manganese, iron, copper, cobalt, magnesium, or a combination thereof; and, c. water to balance.
