Water-soluble macronutrients
Urea for water-soluble fertilizers
For urea in water-soluble fertilizer, check amide nitrogen, biuret and insolubles. Coatings or coarse material in field-grade granules may affect stock filtration.

Water-soluble macronutrients
Potassium nitrate
Potassium nitrate supplies nitrate nitrogen and potassium. Specify N and K₂O separately, and check stock solution concentration at the lowest preparation temperature.

Water-soluble macronutrients
Monoammonium phosphate (MAP)
MAP supplies ammonium nitrogen and phosphorus. Compare granular field products with soluble grades by water-soluble phosphorus, insolubles and stock-solution compatibility.

Water-soluble macronutrients
Water-soluble potassium sulfate
Water-soluble potassium sulfate supplies potassium and sulfur. For chloride-sensitive crops, request a measured chloride value for the grade.

Water-soluble macronutrients
Ammonium sulfate
Ammonium sulfate supplies ammonium nitrogen and sulfur. For fertigation, also assess insolubles, impurities and source water. Total nitrogen alone does not establish drip compatibility.

Water-soluble macronutrients
Water-soluble potassium chloride
Evaluate potassium chloride where the formulation tolerates chloride. Include chloride from the water, other fertilizers and potassium chloride in the calculation.

Calcium, magnesium, sulfur and nutrient solutions
Calcium nitrate for water-soluble fertilizers
Commercial calcium nitrate can contain different nitrogen forms or water of crystallization. Verify soluble calcium, nitrate nitrogen and ammonium nitrogen before calculating stock solutions.

Calcium, magnesium, sulfur and nutrient solutions
Magnesium sulfate
Magnesium sulfate is available in different hydrates. Calculate magnesium and sulfur on an as-received basis and check dissolution rate and insolubles for soluble grades.

Calcium, magnesium, sulfur and nutrient solutions
Magnesium nitrate
Magnesium nitrate supplies nitrate nitrogen and magnesium. Distinguish elemental Mg from MgO and account for moisture uptake when comparing as-received assay.

Chelated trace elements
Iron EDTA chelate
For EDTA-chelated iron, start with chelated iron, source water and root-zone pH. Total iron alone does not establish chelation or stability under the intended conditions.

Chelated trace elements
Manganese EDTA chelate
Compare manganese EDTA with inorganic manganese salts on both water-soluble manganese and the chelated fraction. Consider root-zone pH and competing metals.

Chelated trace elements
Copper EDTA chelate
For copper EDTA, confirm copper reporting basis, solubility and chelated fraction. At low inclusion, check weighing accuracy and premix uniformity.

Inorganic trace elements
Boric acid
Boric acid and borax differ in accompanying ions, acidity and boron content. Compare them on an elemental B basis.

Inorganic trace elements
Borax (sodium tetraborate)
Specify sodium tetraborate hydration state. When comparing elemental boron, also account for sodium and distinguish pentahydrate and decahydrate from other borates.

Inorganic trace elements
Fertilizer-grade zinc sulfate
For fertilizer zinc sulfate, verify water-soluble zinc and hydration state. Maintain separate documentation and impurity requirements for agricultural and feed uses.

Inorganic trace elements
Fertilizer-grade manganese sulfate
For agricultural manganese sulfate, specify water-soluble manganese and hydration state. Check alkalinity, pH and tank partners before attributing precipitation to material purity.
