Base fertilizers are fertilizers that provide the essential nutrients required for plant growth. They are typically applied to the soil before planting or as a top dressing during the growing season. Base fertilizers provide a range of nutrients such as nitrogen, phosphorus, and potassium, which are required for healthy plant growth and development.

The fertilizers can be organic or synthetic and are often tailored to specific plants or soil types. They are often mixed with other fertilizers or supplements to create a balanced nutrient profile for optimal plant growth.

They are an important foundation for plant growth and can significantly impact plant yield and quality.
