Abstract
The present invention provides a new fertilizer comprising water and an organic potassium source wherein the fertilizer composition has a pH range of from 5.5 to 10.0 and a salt index no greater than about 40 as measured by electrical conductivity methods. The organic potassium source is selected from the group consisting of potassium acetate, potassium formate, potassium citrate, potassium succinate, potassium propionate, and combinations thereof. The fertilizer demonstrates lower phytotoxicity damage compared to other sources of potassium for fertilizer products. The fertilizer composition may further comprise nitrogen, phosphorus, sulfur, zinc, boron, calcium, manganese, iron, copper, cobalt, magnesium, molybdenum, inoculants, or a combination thereof.

A fertilizer composition comprising water and a carboxylic acid salt of potassium selected from (1) CH3(CH2)xCOOK wherein x=0-4, (2) MOOC(CR1R2)xCOOK wherein R1═—H or —OH or —COOM and R2═—H or —OH or —COOM and x=0-4 and M=H or K, (3) HO(CR1R2)xCOOK wherein R1═H or a C1 to C4 alkyl group and R2═H or a C1 to C4 alkyl group and x=1-5, (4) CH3CO(CR1R2)xCOOK wherein R1═H or a C1 to C4 alkyl group and R2═H or a C1 to C4 alkyl group and x=1-3, or (5) combinations thereof, and optionally, a second potassium source selected from the group consisting of potassium phosphate, potassium hydroxide, potassium chloride, potassium thiosulfate, potassium silicate and combinations thereof, wherein the organic potassium source combined with the optional second potassium source delivers from 1% to 40% available potassium in the form of K2O in the fertilizer composition and wherein the fertilizer composition has a Storage Stability Value defined by the equation:
