Liquid Potassium Fertilizers

Liquid Potassium to Promote Higher Quality and Protect the Soil

Potassium is the second-most used mineral nutrient after nitrogen, and it is essential for nutrient movement through the plant. Potassium is key in the formation of sugars and starches, and it is also pivotal to regulate water use. A common problem faced by many growers is crop injury that comes with the chloride and hydroxides in many potassium fertilizers. Our liquid potassium fertilizers are chloride and hydroxide free, making them safer for plants and the soil. They can be easily applied with crop protection products and they are suitable to use with a variety of application methods.

Sure-K Liquid Potassium Fertilizer with Phosphate and Nitrogen

Clean, crop-safe potassium

Sure-K is a soluble potash solution designed to encourage fast, robust growth at key reproductive stages. The combination of soluble potash, nitrogen, and phosphate promotes strong growth throughout the growing season. With no chlorides or hydroxides, Sure-K does not contribute to soil toxicity, keeping your soil and your crops healthier longer.

Product Benefits

  • Chloride- and hydroxide-free to prevent soil salinity 
  • Can be mixed with crop protection products  
  • Easy to apply via planter placement, broadcast, top dress, sidedress, foliar, and fertigation 
  • Low risk of crop injury compared to other potassium fertilizers   
  • Can be applied with most crop protection products

Kalibrate Liquid Potassium Fertilizer with Nitrogen and Sulfur

Fast delivery for strong growth

Kalibrate is a sulfate of potash solution also providing nitrogen and sulfur. This unique combination is designed to support early-season growth and ultimately speed up the time to harvest. Kalibrate is designed to resist freezing, and can still be used effectively after freezing. This makes it ideal for cold northern climates and early- or late-season use. 

Product Benefits

  • Many application methods including planter placement, broadcast, topdress, sidedress, and fertigation
  • Chloride- and hydroxide-free to prevent soil salinity   
  • Resists freezing and returns to solution after freezing

Composition Guarantee Analysis

Total Nitrogen (N) 2.00%
.05% Nitrate Nitrogen
1.5o% Ammoniacal Nitrogen
Soluble Potash (K2O) 10.00%
Sulfur (s) 6.00%
6.00% Combined Sulfur

Kapitalize

Unique potassium solution with added sulfur and calcium

Kapitalize is a fast-acting potassium with added calcium and sulfur designed to be foliar applied during the critical reproductive stages of plant growth. Calcium is used by the plant to build cell walls and to grow properly. Ca deficiencies will cause decreased size and quality of seeds, fruit, tubers and cruciferous vegetables which is why this nutrient is especially important in cotton, soybeans, citrus, sugarcane and annual vegetables.

Product Benefits

  • Can be foliar applied with little risk of tissue damage
  • Provides needed nutrition when the plant needs it – during the development of seeds or fruits
  • Promotes strong plant cell growth
  • Improves resistance to stress, drought and disease
  • Easy to apply with other crop nutrients

Composition Guarantee Analysis

Total Nitrogen (N) 3.00%
2.3% Nitrate Nitrogen
0.7% Ammoniacal Nitrogen
Available Phosphate (P2O5) 1.00%
Soluble Potash (K2O) 8.00%
Calcium (Ca) 0.50%
Sulfur (S) 1.00%
1.00% Combined Sulfur

PrimAgro K Biological and Liquid Potassium Fertilizer

Improving nutrient utilization and soil health

PrimAgro K is a liquid potassium fertilizer combined with nitrogen, sulfur, and essential soil microbes. The biological ingredients in PrimAgro K  are designed to restore the beneficial bacteria that are lost to over-fertilization. These bacteria are critical to natural processes that break down nutrients into plant-usable forms. This means PrimAgro K gives plants essential nutrients now, and promotes healthier soil into the future.

Product Benefits

  • Restores beneficial soil microbes  
  • Supplies essential potassium, nitrogen, and sulfur  
  • Improves nutrient retention of the soil 
  • Can be applied with versatile planter placement options, broadcast, as a sidedress or topdress, or through fertigation

Composition Guarantee Analysis

Total Nitrogen (N) 1.00%
0.50% Nitrate Nitrogen
0.50% Ammoniacal Nitrogen
Potash (K2O) 8.00%
Sulfur (S) 6.00%
6.00% Combined Sulfur

Also contains non plant food ingredients.

Contains 401 million total colony forming units per gallon

(4.01×108 total CFU/gallon) of the following bacteria:

Bacillus subtilis 5.30×104 CFU/mL
Bacillus methylotrophicus 5.30×104 CFU/mL

Have us design a custom nutrition plan for you

Potassium levels can be difficult to manage, especially for certain soil types. If your crops are stunted, the leaf margins are scorched or curling, and the fruits or seeds of the plant are lacking, potassium deficiency may be the cause. Our agronomists will use your soil and tissue samples to develop a potassium nutrient plan that works for your crops, soil type, climate and, of course, your budget.

AgroLiquid Scientific Advancements

Traditional commodity fertilizers require large amounts to keep plants well-nourished. This is because much of the nutrients in these fertilizers are lost to soil ions and run-off. They leach away from the field or they become unusable to plants. AgroLiquid formulates nutrients that stay in plant-usable form longer, which means the fields require less total nutrients to achieve the same or better results.

Flavonol Polymer Technology

Our Flavonol Polymer Technology is what allows our fertilizers to provide more plant-usable nutrients. These polymers protect nutrients from bonding with the soil, allowing up to 80% more of your nutrients to be used by plants. This is the result of years of testing and careful formulation.

Application strategies for High NRG-N

Apply as a planter placement to stimulate early growth

Applied as a topdress or sidedress to place nutrients close to root base

Apply with fertigation or as a foliar using the equipment you already have

Applied with other liquid nutrients for complete crop nutrition

Have a specific crop problem you’re trying to solve?

AgroLiquid was founded because there wasn’t a nutritional product that was solving our fertilizer needs; after 35 years of development and research, our chemists, biologists, and agronomists continue to innovate and create the best products on the market. If you have a specific crop problem, ask one of our agronomists and we’ll help you solve it!
