Which fertilizer type is associated with minimal labor and long-term nutrient release?

• A. Liquid fertilizer
• B. Quick-release fertilizer
• C. Controlled-release fertilizer
• D. Foliar spray

Answer: (C)

Nutrients that are released slowly over time with less ongoing work are best provided by a controlled-release fertilizer. Its coating or matrix slows down how quickly nutrients become available, so a single application can feed plants for weeks or even months. This aligns perfectly with the idea of minimal labor and a long-term nutrient supply. Liquid fertilizers act quickly but usually require frequent applications to maintain nutrient levels. Quick-release fertilizers deliver nutrients rapidly and then deplete sooner, needing more frequent reapplications. Foliar sprays deliver nutrients to leaves and don’t establish a long-lasting soil nutrient reservoir, so they don’t support extended soil feeding.
