Fertilizer supplements are additives that are used in conjunction with base fertilizers to provide additional nutrients to plants. They are designed to target specific deficiencies or growth stages in plants.

 Supplements can come in different forms, such as liquid, granular, or powder, and can be organic or synthetic. Some examples of supplements include micronutrient fertilizers that provide essential minerals such as iron or zinc, bloom boosters that promote flower and fruit development, and root stimulants that encourage root growth and nutrient uptake.

Fertilizer supplements can be used alone or in combination with other supplements or base fertilizers to create a customized nutrient profile for optimal plant growth. They are often applied at specific stages of plant growth, such as during the vegetative or flowering stages, to provide the nutrients that the plant requires during those stages.

In summary, fertilizer supplements are additives used in conjunction with base fertilizers to provide additional nutrients to plants. They can be organic or synthetic and are designed to target specific deficiencies or growth stages in plants. Fertilizer supplements can significantly improve plant growth and yield when used properly in a balanced nutrient program.
