Potassium sulfite/potassium bisulfite (KS/KBS) liquid as starter, side-dress, broadcast, foliar and fertigation fertilizers
First Claim
1. A method for fertilizing agricultural crops comprising applying a liquid fertilizer composition comprising potassium sulfite and potassium bisulfite in a ratio of potassium sulfite to potassium bisulfite in the range of about 7.3:
- 2.7 to about 9.2;
0.80 at a pH of about 7.5 to about 8.5 simultaneously with, prior to or immediately after planting seed for the crop.

Abstract
The present invention provides a new liquid fertilizer comprised of potassium sulfite and potassium bisulfite, with neutral to slightly alkaline pH, relatively lower salt index and potentially lower phytotoxicity damage compared to other sources of potassium and sulfur products applied in equal amounts as a starter fertilizer. More specifically, the present invention further relates to methods for fertilizing using a composition of potassium sulfite and potassium bisulfite, particularly as a starter fertilizer, in-furrow fertilizer, side dress fertilizer, and for foliar, broadcast, soil injection and fertigation applications. The fertilizer composition is comprised primarily of potassium sulfite and potassium bisulfite (with the fertilizer grade of 0-0-23-8S).
