Description
Potassium Nitrate Enriched with Micronutrients 13-0-45+ME is a fully water-soluble mineral fertilizer built on potassium nitrate, delivering a high 45% K2O alongside 13% nitrate nitrogen in a single chloride-free, low-salt-index source. The nitrate form is immediately available for root uptake, and potassium itself powers the active transport of that nitrate into the root, so the two nutrients function as one uptake system rather than two separate inputs. EDTA-chelated iron, manganese, zinc, and copper travel alongside the macronutrients, together with readily soluble boron and molybdenum, correcting micronutrient deficiencies that would otherwise limit a crop’s ability to use the nitrogen and potassium it has been given. The grade suits fertigation and foliar programs on fruiting and vegetable crops during bloom, fruit set, and fill, when potassium demand peaks and growers want to avoid encouraging new vegetative growth.
Key Benefits
- Supplies nitrogen the plant can actually assimilate. Molybdenum in the trace-element package is the cofactor for nitrate reductase, the enzyme that performs the first, rate-limiting step of converting absorbed nitrate into usable nitrogen; without it, nitrate builds up in the plant instead of being put to work, so this grade supplies both the nitrogen source and the means to process it.
- Protects calcium and magnesium uptake. Because nitrate carries no positive charge, it does not compete with calcium, magnesium, or potassium for the same root uptake sites the way ammonium does, which is one reason growers favour a nitrate source where calcium-related disorders such as blossom-end rot or tip-burn are a risk.
- Drives fruit fill, sizing, and quality. Potassium regulates stomatal opening, activates the enzymes involved in sugar metabolism, and moves sugars into developing fruit, translating directly into fruit size, colour, and eating quality as the crop ripens.
- Corrects micronutrient deficiency down to the mechanism. EDTA-chelated iron, manganese, and copper stay soluble and available on neutral-to-acidic soils, while boron moves in directly soluble form; zinc specifically drives the enzymatic conversion of tryptophan into the auxin that fruit set depends on, and boron cross-links the pectin that gives pollen tubes the structural integrity they need to reach the ovule, so the package acts directly on fruit set rather than on general plant health.
- Reduces salt-stress risk. Because the formula is chloride-free with a comparatively low salt index, it supplies potassium and nitrate with less osmotic load on the root zone than chloride-carrying potassium sources, a meaningful advantage on salt-sensitive crops.
How It Works
Potassium Nitrate Enriched with Micronutrients 13-0-45+ME dissociates cleanly into nitrate and potassium ions plus a chelated and soluble trace-element fraction, giving a fully soluble, chloride-free nutrient package for fertigation or foliar delivery. Because nitrate carries no positive charge, it does not compete with calcium, magnesium, or potassium for the same root uptake sites the way ammonium does, one reason growers favour a nitrate source where calcium-related disorders such as blossom-end rot or tip-burn are a risk. Molybdenum in the trace-element package is not incidental here: it is the cofactor for nitrate reductase, the enzyme that performs the first step of converting absorbed nitrate into usable nitrogen, so the product supplies both the nitrate and the means to put it to work.
Potassium itself regulates stomatal opening and water relations, activates the enzymes of carbohydrate metabolism, and loads sugars into the phloem for transport to fruit, which is why potassium supply during fruit fill shows up directly as size, colour, and quality. Among the chelated micronutrients, zinc drives the enzymatic step that converts tryptophan into the auxin fruit set depends on, and boron cross-links the pectin that gives pollen tubes their structural integrity, so both act directly on fruit set rather than on general plant health; iron, manganese, and copper round out the package as chelated, root- and leaf-available cofactors across the same neutral-to-acidic pH window.
When to Use Potassium Nitrate Enriched with Micronutrients 13-0-45+ME
This grade earns its place from bloom through the ripening window, wherever potassium demand outruns what the soil alone can supply.
- Potassium Nitrate Enriched with Micronutrients 13-0-45+TE fits fertigation programs from bloom through fruit fill on fruiting vegetables, top fruit, and row crops.
- It supports foliar programs during fruit sizing and ripening, when potassium demand outpaces root uptake capacity.
- The product suits late-season feeding where growers want to sustain potassium supply without adding a nitrogen form that pushes new vegetative growth.
Potassium demand rises fastest under heat, water stress, and heavy fruit load, exactly when soil-level potassium can fail to keep pace with the crop’s requirement; fertigating or foliar-feeding potassium nitrate addresses that gap directly.
The EDTA-chelated micronutrients hold their availability best on neutral-to-acidic soils and irrigation water; above roughly pH 7, calcium, magnesium, and bicarbonate can displace the chelated metal, so high-pH water or calcareous soils reduce their effectiveness.
