Planting & SoilQuestion 45 of 100

Slow-release (controlled-release) fertilizers are advantageous because they do what?

a.Release all nutrients within one day
b.Release nutrients gradually, reducing burn risk and leaching
c.Contain no nitrogen
d.Only work below freezing

Explanation

Controlled-release fertilizers meter nutrients out over weeks or months, lowering the risk of fertilizer burn and reducing nutrient leaching into groundwater. This gives steadier plant growth and fewer applications. They are especially useful for sandy soils where quick-release nutrients leach fast.
