What is a Base Fertilizer?
- Supports Root Development: Minerals like phosphorus aid in the strong growth of plant roots.
- Improves Soil Structure: Organic base fertilizers enhance the soil’s water retention capacity.
- Increases Yield: Provides plants with a strong start during planting, leading to higher harvest quantities.
Base fertilizer establishes a healthy balance between soil and plant.
