US Patent No. 4,698,090
12.7 lbs per gallon (1523 grams/liter) @ 68ºF
Formulated for Soil and Foliar Application, Fertigation, Drip and Micro Sprinklers.
pHighter K is a fertilizer primarily for soil application which can be applied through for micro-sprinkler and drip irrigation systems. pHighter K supplies potassium and increases soil pH (lowers acidity). The added Actagro Organic Acids® help to stimulate plant growth and buffer the toxic effect of aluminum and manganese. The Actagro Organic Acids® will stimulate growth of roots that have been stunted by acidic conditions. Actagro’s experience has shown that organic acids stimulate soil microbes inhibited by excess acidity. pHighter K is a high analysis product and has a liming equivalent similar to common liming materials.

pHighter K contains Actagro Organic Acids® extracted from leonardite in a patented formulation. These organic acids are then combined with liquid plant nutrients in a patented reaction process.
pHighter K contains a high level of soluble potash in a form that reverses soil acidity when applied to soil. The inclusion of Actagro's patented formulation of Actagro Organic Acids® improves the speed of plant response to this fertilizer and soil pH treatment.
pHighter K is an excellent source of potassium for foliar fertilization. The inclusion of Actagro Organic Acids® improves the uptake and utilization of plant nutrients.
pHighter K is formulated to meet the potassium demands of most commercial crops. Fulfilling mid and late season potassium demand should enhance the quality of fruits and vegetables.
pHighter K is compatible with most pesticides and fertilizers, except for calcium containing fertilizers. When trying a new combination, it is always recommended that a small "jar test" be done to verify compatibility of the specific products in combination.
1. Partially fill tank with water and start agitation.
2. Add pesticides or other nutrients.
3. Add pHighter K to circulating water.
4. Fill tank and maintain agitation.
pHighter K is designed for soil application in neutral and acidic soils and for foliar use. Apply directly to soils or inject through irrigation systems where water quality is satisfactory to maintain solubility. Foliar applications should be as a dilute spray. Application rates vary by crop or situation. May be applied through center pivot irrigation systems.
SOIL APPLICATION RATES
ROW CROPS, FIELD CROPS, VEGETABLE AND CUCURBIT CROPS: Apply 4-20 gallons per acres injected beneath the soil surface or through fertigation in irrigation water.
FRUIT AND NUT TREES, GRAPES AND VINE CROPS, STRAWBERRIES AND SMALL FRUITS: Apply 4 - 20 gallons per acre injected beneath the soil surface near the foliage drip line or through fertigation in irrigation water.
ALL FERTIGATION APPLICATIONS: All crops: Use 4-20 gallons per acre per irrigation. Continue irrigation for a minimum of 2 hours after application to flush lines and maximize nutrient distribution.
FOLIAR APPLICATION RATES
CAUTION: Foliar application of pHighter K close to harvest may leave a brown residue on the harvestable portion of the crop. Rainfall, sprinkler irrigation or high humidity should alleviate this condition.
ALL CROPS: Apply 1/2 - 2 gallons per acre in a minimum of 10 gallons of water per acre as a spray. Apply in enough water for good coverage.
