Green!
This fertilizer worked pretty darn good when it was able to absorb into my grass and plants, but one quick point, any fertilizers made with urea tend to evaporate atmospherically quickly. So if you know your fertilizer’s nitrogen source is urea. You want to make sure watering will take place quickly after dispersing it.You also need to be mindful when sulfate is involved, as it can alter the pH. Depending of the pH of your own soil, you may need a little adjustment, but if you use this fertilizer in normal quantities, it shouldn’t affect things too much. If you use enough of this fertilizer, you will notice a lush green from your grass and plants due to the high nitrogen food source.So, I’ve been happy with this fertilizer, and will continue to use it for the time being. If anything changes, I’ll come back and edit this post!

Easy Source of Soluble Nitrogen
Ammonium Sulfate, used properly, adds nitrogen and sulfur to the soil, lowering pH a bit. I use it sparingly in my onion rows every few weeks and it seems to result in larger onion bulbs. Be careful to water it in thoroughly, and avoid applying it directly on stems or foliage. It's great for growing leaves on spinach or cabbage.

Good Stuff, Saved My Peppers!
I used this with my pepper plants and things seemed to improve. They were struggling and nothing helped. Once I decided to drop the PH, everything started to get better. It was just in time to hopefully save the to be overwintered.It has a good value, especially if it is going to save something like it did for me.It is pretty easy to use, just follow the instructions or look on the new for more plant specific guides.I am happy I tried this product. Recommended.

Great for Acid-Loving Plants and Lawn Care
This fertilizer is perfect for my hydrangeas, azaleas, and blueberries. They thrive in more acidic soils, and this ammonium sulfate fertilizer helps create the right conditions by lowering the pH, encouraging healthier growth and vibrant flowers. The 21% nitrogen provides a potent nutritional supplement that promotes lush, green growth, while sulfur helps adjust soil pH, which is especially beneficial for plants like azaleas and blueberries that prefer acidic conditions. I used it on my lawn and it made a significant difference in the color and health of the grass. The grass turned a deeper shade of green, and the growth was smoother. It's great for lawns that need an acidic boost, but it works best in alkaline soil. I appreciate that this fertilizer is made in the USA and meets high-quality production standards.
