Overview

About this product

Quantum SRKZ Extra — a formulation for treating seed of cereal, grain legume and oilseed crops that combines a fertilizer stimulating the root system and a complex of nutrients for germination energy and emergence. It contains 150 g/l of K₂O, P₂O₅ (in the form of phosphite), 30 g/l of zinc, copper, manganese, boron, molybdenum, cobalt, 13 g/l of SO3 and 5 g/l of auxin-type phytohormones; pH 6.0–8.0.

The rate is 1.5–2.0 l/t; the seed dressing solution is prepared with the water reduced by the dose of fertilizer, then the fertilizer is added. Treated seed is dried or sown at once.

Method

Treatment of seed of cereal, grain legume and oilseed crops by the standard method (for example, with PS-10 machines): 1.5–2.0 l/t

First prepare the seed dressing solution, reducing the initial amount of water by the dose of micronutrient fertilizer, then add Quantum SRKZ and bring to the nominal volume
