We know potassium is important, but why? Potassium is a macronutrient that plays a large role in a plant’s success. AgroLiquid offers high-efficiency liquid potassium products designed to deliver this nutrient effectively and safely – Sure-K and Kalibrate.

Why potassium is important for crops

Potassium isn’t a building block like nitrogen or phosphorus. Instead, it’s considered a regulator that drives many of the plant’s processes.

Roles where potassium helps:

  • Water management: Potassium regulates the opening and closing of stomata, which controls the plant’s water use and helps it resist drought and wilting.
  • Nutrient and sugar transport: It helps in the movement of water, nutrients, and carbohydrates (sugars and starches) throughout the plant, from roots to leaves and into developing fruit or grain.
  • Enzyme activation: Potassium activates over 60 different plant enzymes, which are needed for processes like protein synthesis and energy production.
  • Stress and disease resistance: Potassium strengthens cell walls and helps the plant withstand environmental stress, disease, and pests.

The AgroLiquid advantage: Sure-K and Kalibrate

Commodity potassium fertilizers often require high application rates because a large percentage of the nutrient can quickly become unavailable in the soil. AgroLiquid’s use of proprietary Nutriq® Technology meets this challenge, since it protects the potassium so it remains plant-available longer. As a result, this allows growers to achieve the same or better results with lower concentrations.

In addition, both Sure-K and Kalibrate are chloride- and hydroxide-free, which prevents the long-term soil health damage sometimes associated with conventional potash sources.

Sure-K flexibility

Sure-K is a high-efficiency soluble potash designed to provide sustained potassium at important reproductive stages. It stimulates the growth of fruit, seeds, and tubers, leading to higher quality and greater yields.

  • Sustained nutrition: It’s engineered to keep potassium available through budding, blooming, and production, making sure the plant has the potassium it needs when demand is highest.
  • Application versatility: Sure-K can be applied in numerous ways, including foliar, fertigation, and side-dress applications, and is compatible with most other nutrients and crop protection products.
  • Learn more about Sure-K.

Kalibrate features

Kalibrate is a full-season liquid potassium source that also delivers sulfur. It’s specifically engineered for effective application at planting.

Sulfur is needed for crops because it is a structural component for synthesizing sulfur-containing amino acids. It drives nitrogen use efficiency, since without adequate sulfur, the plant cannot efficiently convert absorbed nitrogen into usable protein. Plus, sulfur is necessary for chlorophyll formation and directly impacts the quality of the final harvest.

  • Early-season delivery: Kalibrate provides plants with nutritional support from the moment they start growing.
  • Sulfur: Sulfur is important for amino acid, protein, and oil formation. Kalibrate’s inclusion of crop-available sulfur helps, especially in sandy soils or high-rainfall areas where sulfur can more easily leach away.
  • Freeze resistance: Kalibrate is formulated to resist freezing, making it an ideal choice for fall or early-spring delivery in northern climates.

Choosing your potassium source

The decision between Sure-K and Kalibrate often comes down to timing and the need for sulfur. Kalibrate is an excellent choice for application during planting where early potassium and sulfur are needed. Sure-K provides a highly flexible solution for in-season application to support reproductive development and late-season needs.

But you don’t really need to choose. Both potassium products deliver the high-efficiency potassium your crops need to be successful, and you get the most out of every acre while promoting soil health over the long term.

It’s time to plan! You’re considering your crop type, growth stages, soil conditions – and how best to work with everything. Of course potassium contributes to everything from disease resistance to water regulation. But what do you need?

AgroLiquid offers four potassium products. What’s the difference between them, and what’s right for your crop strategy? Let’s break it down.

  • Kalibrate

Potassium + sulfur

We’ll start with Kalibrate®. Kalibrate is a potassium fertilizer with added sulfur. It’s also chloride- and hydroxide-free, which means it also provides nourishment to plants and trees without harming the long-term health of the soil.

Kalibrate helps plants access potassium and sulfur from seedling to harvest. It can be used by itself to provide plants with an extra source of potassium and sulfur, or it can be used in combination with other AgroLiquid products to provide a complete fertilizer program.

Kalibrate is designed to be easy to use and apply, so growers can give crops and trees what they need without expending lots of extra time and money. Just what everyone wants!

See how Kalibrate performed in our field tests.

  • Kapitalize

Potassium + sulfur + calcium

Next up is Kapitalize™. Kapitalize is designed to be foliar applied during the reproductive growth stages. Adding calcium and sulfur to the potassium foliar fertilizer makes the nutrients more available.

Tank mixing conventional calcium products can cause issues, and calcium is very reactive. Kapitalize is designed to be combined and immediately applied with other AgroLiquid products, including phosphorus.

Like all our products, Kapitalize is manufactured with the highest quality raw materials. (You can Kapitalize on that!)

Check out our latest studies on Kapitalize.

  • PrimAgro® K

Potassium + nitrogen + sulfur biofertilizer

PrimAgro K is a potash biofertilizer combining potash with soil-conditioning biologicals. This not only provides nitrogen, potassium and sulfur, but it also improves nutrient retention and utilization year over year.

PrimAgro K helps make nutrients more mobile and available for plants to use. This helps row crops requiring regular replenishment of nutrients. With PrimAgro K, these nutrients will be available to crops longer, and there is less environmental loss.

See our PrimAgro research.

  • Sure-K

Potassium + nitrogen + phosphate

Sure-K® is a liquid potassium that gives plants the nutrients they need during reproductive stages. The Sure-K formula provides increased use at lower concentrations. Using Sure-K has provided the same or better results than standard potassium fertilizers – while using less product!

Sure-K allows plants to better process sugars, which helps produce larger, higher quality yields, while also making the crops better able to resist stressors. Plus, Sure-K uses no chlorides or hydroxides.

See our latest Sure-K studies.

Choices

For comprehensive soil health and long-term benefits, PrimAgro is a great choice. If you’re focusing on foliar, Kapitalize delivers targeted nutrition you may need. If you’re looking for a cost-effective and versatile product, Kalibrate may work for you. And when efficiency is a main focus, Sure-K offers a concentrated option.

No matter your needs, AgroLiquid has a potassium solution for you. If you want any more assistance in differentiating between products, please don’t hesitate to contact us. We’re always happy to talk strategy.
