Quantum Molybdenum Chelate (Mo) — a liquid concentrated molybdenum micronutrient fertilizer with molybdenum 40 g/l in chelated form, phosphorus and potassium, especially for legumes and acidic soils.

Main advantages

Molybdenum 40 g/l in chelated form — well absorbed
Acidic soils pH < 5.5 — especially effective per the maker
Legume seed 0.5 l/t — check with inoculants
Soybean at budding 0.3–0.7 l/ha — the maker's rate
Fertigation 100 ml per 1 m³ — drip irrigation

Overview

About this product

Quantum Molybdenum Chelate (Mo) — a concentrated molybdenum micronutrient fertilizer with molybdenum in chelated form for preventing and eliminating molybdenum deficiency on all crops. It contains 40 g/l of molybdenum, 60 g/l of P₂O₅, 70 g/l of K₂O and 5 g/l of nitrogen; pH 7.5–8.5, density 1.10–1.20 kg/l.

Per the maker, it is especially effective on acidic soils (pH < 5.5) and for legumes: soybean, pea, lucerne. Legume seed is treated at 0.5 l/t; as a foliar on soybean and pea 0.3–0.7 l/ha, on wheat, barley and maize 0.3–0.5, on other crops 0.2–0.5 l/ha.

In fertigation 100 ml per 1 m³ of water.

With molybdenum deficiency (by visual or laboratory diagnosis), for all crops, especially fruit, berry and vegetable crops, treatments are repeated at 7–10 day intervals

Method: Treatment of legume seed: 0.5 l/t
Foliar feeding with standard sprayers: spray solution 200–400 l/ha for vegetable crops, 500–1000 l/ha for grapes and fruit crops
Conditions: The maker points to particular effectiveness on acidic soils (pH < 5.5) with low molybdenum availability
Prepare the spray solution immediately before application: fill the tank 2/3 with water and, while stirring, add the components one at a time, waiting until the previous one is evenly mixed
Tank mix: Joint application with plant protection products and other fertilizers is possible, but do not combine feeding with herbicide treatment at the early stages of plant development
Before mixing, check compatibility: a test spray solution must not form a precipitate, slight turbidity is acceptable
