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.
Nitrogen is found in all living cells. Without nitrates, a plant cannot grow and produce flowers and seeds. This is primarily because nitrogen is an essential component of plant proteins and chlorophyll, which is necessary for the process of photosynthesis. Photosynthesis is how a plant makes food. Without nitrates, photosynthesis cannot occur, and the plant will die from a lack of food.
Without the right nutrients and growing environment, your plants will grow poorly, and they can become susceptible to insects and diseases. There are three major nutrients that can limit the growth of your plants and a variety of conditions that your plants need to sustain healthy growth. The three nutrients that plants use in the greatest quantities are nitrogen, phosphorous and potassium. Soils that are deficient in these nutrients produce stunted plants that are more likely to suffer damage from diseases and insects. In most cases these elements are naturally present in sufficient quantities to support the growth of most plants.
