How to Choose the Right Type of UREA Fertilizer
Choosing the right UREA fertilizer helps improve nitrogen efficiency and crop yields. Here are three common types:
Granular UREA: Ideal for soil application before planting or as a side dressing. Suitable for cereals, vegetables, and fruit crops.
Liquid UREA: Best for foliar spraying and quick nitrogen absorption. Useful during fast-growing stages.
Water-Soluble UREA: Perfect for fertigation and greenhouse use. Dissolves easily and ensures even nutrient delivery.
Select your UREA type based on your crop, irrigation method, and soil condition. The right choice boosts plant health, reduces nitrogen loss, and supports sustainable farming.
