Step 1: Understanding Fertigation
Fertigation requires water-soluble fertilizers to be delivered efficiently through a drip system.
Step 2: Evaluating Options
- Urea: Highly soluble, making it suitable.
- Super Phosphate: Poor solubility, leading to clogging, making it unsuitable.
- Gypsum: Moderately soluble but usable in small quantities.
- Muriate of Potash: Highly soluble, making it suitable.
