Industry guide / Agriculture and nutrition
Agriculture and Water-Soluble Fertilizers
Choose nutrient sources for the crop, water source and application method. Check solubility and compatibility at the actual stock-tank concentration and minimum temperature.
Process guide
Stock solutions, micronutrients and water quality
Explore 5 processes and 26 distinct materials. Choose a process to compare candidates, operating conditions and trial methods.
Stock solutions dissolve slowly and nutrient labels use different bases
Establish the conditions
Check the nutrient reporting basis, solubility, water-insoluble matter and chloride requirement.
Materials and their roles
Trial and comparison. At the intended water temperature and stock concentration, measure dissolution and residue. Distinguish elemental values from N, P₂O₅ and K₂O declarations and check the chloride load.
Mixing stock solutions causes precipitation
Establish the conditions
Record source-water hardness and pH, stock solution concentration and tank arrangement.
Materials and their roles
Trial and comparison. At the intended concentration and temperature, compare time to dissolve, precipitate formation and filter residue. Evaluate separate stock tanks where incompatibilities are expected.
Which iron chelate suits alkaline water?
Establish the conditions
Identify the ligand, chelated metal fraction and working pH range. For Fe-EDDHA, check the reported ortho-ortho fraction.
Materials and their roles
Trial and comparison. Confirm the ligand and chelated metal first, then evaluate stability at the source-water and root-zone pH. Compare Fe-EDDHA grades on the same isomer reporting basis.
How should trace-element salts be compared on an elemental basis?
Establish the conditions
Select by element content, salt form, crop needs, application route and water quality.
Materials and their roles
Trial and comparison. Compare actual salts and hydration states on an elemental basis. Verify project limits for the crop, application method and water source.
Which inputs suit high-alkalinity irrigation water?
Establish the conditions
Separate acidification, chelation and the use of humic substances. Select each material against its intended function.
Materials and their roles
Trial and comparison. Assess alkalinity adjustment separately from functional organic ingredients. Record pH, solubility, precipitate and compatibility with the base fertiliser.
