Classify Different Types of Drip Fertigation Techniques and Their Applicability to Different Crops. Compare Drip Fertigation with Traditional Fertilization Methods in Terms of Efficiency, Resource Utilization, and Environmental Impact ?
Fertigation is an efficient method of nutrient application in which fertilizers are injected through an irrigation system. Synchronization of nutrient supply and crop demand enhances nutrient-use efficiency. Fertilization using granular fertilizers typically involves fertilizing once, twice, or three times during the growing season. There are many benefits to implementing a fertigation system for crop production. Fertigation can synchronize nutrient supply and crop nutrient requirement, which enhances water-use efficiency, nutrient-use efficiency, and yield, while also reducing nutrient losses via leaching, ammonia volatilization, denitrification and weed pressure. Fertigation also significantly saves field trips and labor costs. However, it has drawbacks, including high initial investment cost and the need for constant maintenance and Clogging risks.
Advantages
1. Synchronizing nutrient supply and crop requirement
2. Greater crop yield
3. Greater nitrogen-use and water-use efficiency
4. Reduced labour time
5. Reduced groundwater contamination
6. Suppressed weed pressure
There are four main types of drip irrigation:
1. Soaker hoses (also sometimes known as porous soaker lines),
2. Emitter systems,
3. Drip tapes, and
4. Micro-misting systems.
Each system has different features and benefits depending on your needs
