Slow-release fertilizers are designed to gradually release nutrients into the soil over an extended period of time. This controlled release allows plant roots to absorb nutrients consistently, promoting healthy growth without the risk of nutrient leaching or rapid depletion that can occur with other types of fertilizers. These fertilizers often use coatings or specific chemical formulations that regulate the timing of nutrient availability in accordance with soil conditions and microbial activity.

In contrast, liquid fertilizers provide immediate nutrients that are quickly available to plants but do not offer the long-term benefits associated with slow-release formulations. Fast-acting fertilizers also release nutrients rapidly, which can lead to a quick boost in plant growth but may not support sustained feeding over time. Organic fertilizers can be slow-acting, but they vary in nutrient release rates; thus, they are not specifically categorized or guaranteed to release nutrients over an extended duration as consistently as slow-release fertilizers do.
