Start with the crop. Build from the soil.

Nitrogen is generally important for vegetative growth and yield potential. Phosphorus supports establishment and root development.

Select potassium and zinc inputs according to soil and crop requirements, not a routine blanket application.

Urea and phosphorus fertilizers are commonly used. Manage potassium and zinc according to soil and crop requirements.

Maize has significant nutrient demand and requires balanced nutrition rather than nitrogen alone.

Balanced nutrition is important for vegetative growth, flowering, boll development and crop quality.

Nutrient management should consider crop duration, soil fertility, irrigation and expected yield.

Potassium is particularly important for tuber development and crop quality.

Nutrient requirements vary with soil, variety and production system.

Calcium and balanced potassium nutrition can be particularly important for fruit quality.

Balanced nutrition supports plant development, flowering, fruit formation and quality.

Adjust nutrient management to tree age, crop load, soil conditions and leaf/soil analysis.

Manage nutrition according to tree age, flowering, fruit development and orchard conditions.

Use soil/plant analysis and crop requirements to decide whether micronutrients are needed and to develop an orchard programme.

Confirm nutrient requirements from soil/plant analysis and local agronomic advice before choosing products or rates.

Banana has a high nutrient demand, particularly for potassium.

Balanced nutrition is important for fruit development and quality.

Pulses are a broad crop group, not a single fertilizer programme. Identify the crop and variety, soil conditions and previous crop before selecting nutrients.

If considering a microbial product such as Rhizobium, confirm the crop-microorganism match, product quality, storage and label instructions with a qualified agronomist.

Vegetable nutrient needs vary by crop, variety, soil, growth stage and production system. Use the individual potato, onion, tomato and chilli guides as starting points, not interchangeable prescriptions.

For drip irrigation, greenhouse production or foliar feeding, confirm the suitability, concentration and compatibility of water-soluble or liquid products.

Different fruit crops have different nutrient priorities. Refer to the individual fruit guides and soil/plant analysis rather than using a single mixture for every crop.

Consider flowering, fruit formation, crop load and quality requirements when discussing a programme with a qualified agronomist.

Consider tree age, crop load, flowering, fruit development, irrigation water and orchard soil conditions. Leaf and soil analysis can guide nutrient decisions.

Where fertigation is used, follow the product's approved application method and compatibility instructions.

Nitrogen fertilizers are commonly used for fodder crops, but nitrogen alone is not a substitute for balanced nutrition.

Identify the fodder crop, growth stage and soil-test requirements before agreeing a programme and application timing with an agricultural professional.

Nursery and garden plants vary in their nutrient needs. Identify the plant, growth stage, growing medium and irrigation water before choosing a product.

Water-soluble and liquid fertilizers are used in nurseries. Use only suitable products and follow label concentrations, application methods and compatibility instructions; more fertilizer is not necessarily better.
