TopKrop SlowRelease Foliar Fertilizers

TopKrop SlowRelease liquid foliar fertilizers provide an alternative nitrogen source while delivering supplemental plant nutrients throughout the growing season.

Our products are true foliar fertilizers that stick to the plant, break down with UV light, and slowly release nitrogen into the plant through the leaves.

TopKrop SlowRelease foliar nutrition products are intended to be applied in conjunction with a pre-existing fertilizer program to provide crops with all their nutritional needs.

Manufactured locally in Delisle, Saskatchewan.

How does foliar nutrition work?

Foliar fertilizer applications increase chlorophyll on the leaf, which is the green pigment in the plant. The chlorophyll acts like a tiny greenhouse, trapping photons on the leaf longer – dramatically increasing the rate of photosynthesis.

Increased photosynthesis will increase the water and nutrient uptake through the roots, producing bigger, healthier crops.
