proKa^® — Best practices for a well-balanced soil

Proka is a liming and fertilizing agent rich in calcium, potassium, magnesium, sulphur and micronutrients: boron (B), zinc (Zn) and copper (Cu).

This product is designed to correct pH and, at the same time, enrich the soil with potassium, with more than 4%.

Proka applications have improved soil health by increasing the nutrients that help achieve optimum yield and better crop quality.

The benefits of calcium, potassium and sulphur for crops

The calcium and potassium contained in Proka are beneficial to crops:

Potassium is responsible for photosynthesis and protein synthesis.
Potassium helps crops become more drought tolerant.
Sulphur is a catalyst that helps the exchange of nutrients, including calcium (Ca), magnesium (Mg) and potassium (K), in plants.
Potassium sulphate helps plants develop digestible protein and increases fibre to improve crop quality, including test weight.
Calcium carbonates and hydroxides raise pH and, at the same time, support microbial activity in the soil as well as the uptake of nutrients that benefit plants.

Lime and fertilize in a single pass

How often do we hear: “Time is money.”

Proka applications allow growers to lime and fertilize in a single pass in the field.

This saves time and money and ensures a good distribution of nutrients across the field.

Benefits for soil health and for your bottom line

Soil applications of Proka are not only good for soil health, they are also profitable. The nutrient value of Proka ranges from $360/ha to $380/ha, or $145 to $155/acre, while the cost of the product is much lower.

Growers save around 35%. Visit our website to find the retailer in your area and make Proka part of your fertilization strategy!
