Applying Ammonium Sulfate: Timing and Technique

Work ammonium sulfate into soil 2 weeks before planting—never at planting time (burns roots). After planting, feed every 10 days with balanced water-soluble fertilizer. Excess nitrogen = lush leaves, no fruit.

Match nutrients to crops: N for leafy greens, P for fruiting veg (tomatoes, peppers), K for roots (carrots, beets). Mulch to stabilize moisture and temperature.
