Fast-acting potassium fertilizer with added sulfur and calcium

As a primary plant nutrient, potassium is a vital component in a variety of plant processes, including the development of seeds, fruits and tubers. Calcium is also important for the proper plant development and high yields. Kapitalize™ is a fast-acting potassium fertilizer formulated to provide critical nutrition to crops through these reproductive stages. This agricultural potassium fertilizer is easy to apply to all different types of crops, including vegetables, row crops, fruit trees and more.

Fast-Acting Potassium Fertilizer

Kapitalize is a fast-acting potassium fertilizer with added calcium and sulfur. Calcium is used by the plant to build cell walls and to grow properly. Calcium 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. This agricultural potassium fertilizer can be easily applied at critical stages to help increase yields and quality, while also helping vegetables, crops and trees resist disease, pests and drought.

Potassium Foliar Fertilizer

Kapitalize is designed to be foliar applied during the critical reproductive stages of plant growth. The addition of calcium and sulfur in the potassium foliar fertilizer makes more nutrients available to the plants and trees. Calcium is highly reactive, and tank mixing conventional calcium products can be troublesome. Kapitalize has been formulated to be combined and immediately applied with other AgroLiquid products, including our phosphorus products. Like all of our products, Kapitalize is manufactured with the highest quality raw materials. We have eliminated potentially harmful bi-products that can cause crop injury.

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

Advantages of Agricultural Potassium Fertilizer

Applying agricultural potassium fertilizer to your vegetables, grains, tubers, or fruit trees can provide a number of benefits. The unique formulation of Kapitalize not only makes it easy to apply, but also helps to prevent nutrient tie-up in the soil. Since this potassium fertilizer also includes calcium and sulfur, Kapitalize helps to bolster multiple parts of the plant as it grows. This is particularly useful for crops and fruit trees with high potassium, calcium, and sulfur requirements, such as citrus fruits, cotton, tubers, and cruciferous vegetables. Unlike many potassium fertilizers for crops, Kapitalize won’t interfere with phosphorus fertilizers.

Kapitalize is formulated to avoid reaction with phosphorus in mixing, providing superior flexibility and options for application. It is well-suited to use foliar application on crops that respond well to potassium and calcium.

After extended periods in a mixed solution with other products, the effects of chelation may dissipate, resulting in the development of sediment. To avoid this, mix only the amount needed for a single application.


Have us design a custom nutrition plan for you

An AgroLiquid nutrition plan is dependent on your location, climate, soil conditions, and goals with your crop. All of our tailored programs start with reviewing your soil samples with one of our expert agronomists. After our analysis, our team will provide you with a couple options that will help you meet your goals on a budget that won’t break the bank.

AgroLiquid Scientific Advancements

Though all plants need similar nutrients, not all fertilizer deliver them the same way. AgroLiquid fertilizers are designed to give crops the nutrients they need at the right time. This helps to optimize growth from germination through harvest. In addition, our high-efficiency liquid fertilizers increase nutrient utilization while avoiding nutrient toxification and salt toxificiation. This means you benefit from the same or increased yields, while improving overall soil quality.

Nutriq Technology

This bonds with your nutrients and creates a protective layer that makes up to 80% more of your nutrients available to plants. It sounds like magic, but it’s just science.
