(NH4)2SO4 Ammonium Sulfate breaks down fast to NO3 and is up taken by the plant very quickly. Therefore it helps to Green up. However it is an acid forming fertilizer because for every 1 pound of N you are applying 1 1/4 Pounds of Sulfur. BTW the Sulfur also helps in green up and is an important part of Photosynthesis. Old school chemistry was Iron Sulfate and Ammonium sulfate to create a Dark Green color. Iron Sulfate tears up your pump and stains everything.

Take Ammonium Sulfate a step farther and note the soluble blend comes in 51 pound bag. The reason goes back the Agriculture and the days of 300 gallon Ag spray tanks. Today most farmers are using 500 tanks. 51 pound in a 300 gallon is 17 pounds per 100 or 0.17 (approx 1/5 #) per gallon as a SURFACTANT. Because Ammonium Sulfate is up taken so fast it acts as a surfactant to help up take the Pesticide being sprayed. Add that 1/5 of a pound of 21-0-0 to Roundup to get a quicker kill. etc.

The Below Picture shows NO3 Ammonium Nitrate as the final stage of Nitrogen being broken down before being Up Taken. 34-0-0 is Ammonium Nitrate and cheaper per pound than 21-0-0 Ammonium Sulfate. Ammonium Nitrate is up taken by the plant quicker than 21-0-0 but doesn't give as quick of a green up.
