TopKrop SlowRelease Foliar Fertilizers
TopKrop SlowRelease liquid foliar fertilizers provide an alternative nitrogen source while delivering supplemental plant nutrients throughout the growing season.
This low salt, UV activated formulation is completely crop safe and will stick to the leaf and feed the plant for up to 30 days.
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.
