Potassium Thiosulfate 0-0-25-17S

Potassium + Sulfur (0-0-25-17S)

Potassium and sulfur in one liquid.

K + plant-available S; ~+11 bu/ac corn on S-short fields Source: Purdue/Iowa State corn-S trials (avg +11 bu/ac, responsive sites) · S response only where deficient (~half of fields, low-OM/sandy/eroded). K adds yield only on low-K soils. Not a guarantee.

What it is

Potassium + Sulfur (0-0-25-17S)

Potassium thiosulfate at 0-0-25 with 17% sulfur, delivering potassium and plant-available sulfur together. Bulk sizing. Hay note: every harvested ton removes ~45–60 lb K₂O vs just 13–15 lb P₂O₅ (Penn State Extension): potassium is the nutrient hay ground depletes fastest.

The research

The evidence behind Potassium Thiosulfate 0-0-25-17S, ours and everyone else's.

Every figure carries its source. Independent research shows where the agronomy holds up; our own replicated trials show it on the ground.

AgriTec trials

The full AgriTec wheat program yielded 98.8 bu/ac versus 78.6 on the untreated check, a +25.7% lift on a replicated trial (6 treatments × 4 reps, 24 plots) with identical starting soil (pH 5.4).

Agricenter International trial · Memphis, TN
Replicated on-farm trial partnerships across the Southeast: peanut (Auburn University), soybean (Alcorn State University), and forage (Tuskegee University).

Independent research

Potassium raises yield and stand life mainly below critical soil-test K; on a K-deficient fescue field, K drove roughly half of a +2 ton/ac gain.

Ohio State Extension; University of Kentucky forage-K trial
Corn responded to sulfur in about half of trials (the S-deficient, low-OM and sandy fields), averaging ~+11 bu/ac on responsive sites.

Purdue (26 of 55 trials) + Iowa State (47 sites)
Ammonium sulfate recovered ≥10–17% herbicide control in hard water by tying up antagonistic cations.

Independent findings are general to the nutrient or mechanism and describe where a response is likely, not a guarantee on your field. Match them to your soil test; an AgriTec agronomist will help.
