Special Purpose Fertilizers are defined as?

Special Purpose Fertilizers are designed and packaged for specific uses or for certain types of plants, addressing the unique nutrient needs of those plants or the particular growing conditions they require. This specialization can include formulations designed for flowers, vegetables, trees, or other specific categories of foliage, ensuring that the correct balance of nutrients is provided for optimal growth and development.

The other options focus on general classifications or characteristics that do not define special purpose fertilizers specifically. For example, fertilizers containing all three macronutrients refer to complete fertilizers, while those that release nutrients slowly pertain to slow-release fertilizers. Additionally, something that is missing at least one major component would not be classified as special purpose but rather as an incomplete fertilizer. Thus, the significance of option B lies in its focus on the tailored nature of special purpose fertilizers.
