Fertigaatio

Fertigaatio is a term used in some languages to denote the practice of applying fertilizers through irrigation systems. It combines fertigation with irrigation delivery to supply nutrients directly to the plant root zone. The technique is most commonly implemented with drip or micro-irrigation systems, but can also be used with sprinkler systems in some setups. The fundamental idea is to dissolve fertilizer in irrigation water and inject it into the irrigation stream.

Implementation relies on a fertilizer injector or metering pump, correct chemical compatibility, and reliable water supply. Operators adjust dosing based on crop needs, growth stage, soil tests, and irrigation schedules. Modern setups may integrate EC and pH sensors, programmable controllers, and automation to vary nutrient concentration in real time.

Benefits include efficient nutrient use, reduced fertilizer losses through leaching and volatilization, and the ability to match nutrient supply with water availability. It allows rapid response to crop demand and can improve yields and quality, especially in greenhouse and high-value crops. Risks include equipment costs, potential clogging from insoluble residues, fertilizer precipitation, and the need for careful management of irrigation water quality to avoid root salt injury or microbial growth.

Fertigaatio is related to fertigation and is widely used in modern horticulture, nursery production, vineyards, and turf management. Its effectiveness depends on crop type, climate, irrigation method, and fertilizer formulation, with best results achieved through integrated nutrient management and regular monitoring.
