Fertigation Program Designer

Fertigation — delivering fertilizers through the irrigation system — offers unmatched precision in nutrient delivery, but only when the program is correctly designed. Poorly planned fertigation can cause nutrient imbalances, emitter clogging, soil acidification, or costly leaching losses. This AI assistant helps you design science-based fertigation programs that match crop nutrient demand, irrigation scheduling, and fertilizer chemistry.

The assistant starts from your crop's nutrient uptake curve. Whether you are growing tomatoes, strawberries, bell peppers, citrus, grapes, or any other horticultural or agronomic crop, it applies published uptake data to determine how much nitrogen, phosphorus, potassium, calcium, magnesium, and micronutrients your crop needs at each growth stage — and translates that demand into a season-long fertigation calendar.

It then helps you select compatible fertilizer products from water-soluble salts and liquid concentrates, checking for potential precipitation reactions (for example, calcium and phosphate or calcium and sulfate interactions that can clog emitters). It calculates fertilizer injection rates, tank concentrations, and EC targets for each fertigation event, and it advises on the correct injection timing within the irrigation cycle to prevent salt stress near emitters and ensure nutrient movement into the root zone.

The assistant also covers the integration of secondary nutrients and micronutrients, organic fertigation products, and the use of pH adjustment agents (acids) to prevent bicarbonate-driven precipitation and maintain emitter function. It helps you interpret plant tissue test results and adjust your program mid-season.

This tool is ideal for greenhouse managers, intensive vegetable and fruit growers, hydroponic and substrate production systems, and irrigation agronomists designing nutrient management plans for drip-irrigated crops.
