Determining the weight of 100 CDs depends on whether only the CDs are weighed or if the CDs have sleeves or jewel cases. A single CD by itself weighs about 0.58 ounces. Therefore, 100 CDs by themselves weigh 58 ounces.
Plants need nitrates to develop green leaves. Nitrogen, potassium and phosphorus are the three major nutrients plants need to grow successfully. In particular, nitrogen is responsible for foliage development. Plants use nitrogen in the form of nitrates, which is nitrogen mixed with oxygen. They usually absorb nitrates from the soil.
Consider the Importance of Nitrogen. In order to grow, grass requires plenty of nitrogen in its soil. Nitrogen helps the grass develop a deep-green color and thick, lush growth. Without proper amounts of nitrogen, grass appears stunted and yellow, and the lawn may have bare patches where grass won't grow.
