1. Each year, sulfur fertilizers help North American farmers produce the most abundant food supply on earth. Of all sulfur sources none is more versatile than ammonium sulfate.
2. Plants use sulfur to synthesize proteins and form chlorophyll that is vital to the internal food-producing process of photosynthesis. Without sulfur, your Laramie lawn cannot make efficient use of other nutrients, and will not reach its full potentia l.

1. Nitrogen is the key nutrient in a lawn fertility program. A healthy turf grass plant is three to five percent nitrogen.
2. A dark green thick lawn requires regular nitrogen applications.
3. Nitrogen fertilization is almost always required for good growth.
4. Nitrogen is a component of :

1. Chlorophyll

2. Proteins

3. Amino Acids

4. Plant Growth Hormones

5. Enzymes

1. In addition, many growers realize that sulfur fertilization increases yield and quality. Because nitrogen efficiency is closely tied to sulfur nutrition, the plant better utilizes available nitrogen when provided with adequate sulfur.
2. Sulfur promotes healthy plant development by improving:

1. Plant iron uptake

2. The synthesis of protein

3. Photosynthesis

4. Disease resistance

5. Winter hardiness of perennial plants

6. Nitrogen fixation by legumes
