Fertigation 5

Fertigation is the process of applying water-soluble fertilizers to crops through irrigation systems like drip or sprinkler irrigation. It allows for fertilizer to be dissolved, diluted and distributed with water directly to plant roots. The objectives of fertigation in microirrigation are to maximize profits by applying the right amount of water and fertilizer at the right time while minimizing environmental impacts like fertilizer leaching. Some advantages include more uniform fertilizer distribution, flexible application timing, reduced fertilizer and nutrient losses, and lower costs. Disadvantages can include contamination hazards and needing expert installation and handling of liquid fertilizers.

Fertigation 5
- 1. Fertigation Application of fertilizer materials via the irrigation system. Fertigation is a process in which, fertilizer is dissolved, diluted and distributed along with water in drip or sprinkler irrigation system. In other word, fertigation is the process of application of water soluble solid fertilizer or liquid fertilizers through micro irrigation system. Why we needfertigatin Uneven growth in fertilizer consumption resulting in state-wisecrop-wise variation in consumption. Mining of nutrients fromthe soil at alarming rate (soilfertility depletion due to inadequate and imbalanced fertilizer use). Decline in crop responseto fertilizer. Stagnation in fertilizer production. Weakening relationship between fertilizer useand food grain production. Increasing dependenceon fertilizer imports. Objectives of fertigationinmicroirrigation • Maximize profit by applying right amount of water and fertilizer at right time. • Minimize adverseenvironmental effects by reducing leaching losses of fertilizers and other chemicals below the root zone. Advantages Relatively uniformfertilizer applications and distribution Flexibility in timing of application Less fertilizers used and minimum nutrient loss Reduced costs, savelabour and energy Even distribution of nutrients throughoutthe root zone Reduced energy demand Disadvantages Potential contamination hazard from equipment malfunctions Backflow prevention devices required Careful handling of liquid fertilizer required May requireexpert design and installation
