Fertigation is a modern agricultural practice that combines fertilization and irrigation. It involves delivering nutrients directly to plants through the irrigation system, allowing for more efficient nutrient uptake. This method helps ensure that plants receive the right amount of nutrients at the right time, promoting healthier growth and higher yields. By using fertigation, farmers can reduce the amount of fertilizer needed, minimizing waste and environmental impact. This technique is particularly beneficial for crops grown in greenhouses or on farms with limited water resources, as it optimizes both water and nutrient use, leading to more sustainable farming practices.
