Buying Guide for Ammonium Sulfate 21-0-0

Understanding Ammonium Sulfate

When I first came across ammonium sulfate, I learned that it’s a popular fertilizer known for its high nitrogen content, specifically 21% nitrogen. This makes it an excellent choice for promoting lush, green growth in plants. The “0-0” indicates that it contains no phosphorus or potassium, which means it’s primarily a nitrogen source.
