Effects of Coffee Residue Mulch on the Height and Number of Leaves of Onion Chives

I. Introduction:

A. Background of the Study:

Plants are necessary in everything we do. Be it for eating, medicine, or even ornamental purposes, we still need plants. Fertilizers are like the vitamins for plants – they are not required yet the simple use of them can boost the quality of crops by folds. Fertilizers range from company manufactured items to compost heaps, which means they are the organic leftovers used again for the benefit of the nutrient cycle.

Coffee is the awakener of the human race. Known to have antioxidants, it is also a very healthy drink, when consumed in moderate amounts. Steep hillsides are more frequently used for coffee plantations. In coffee districts, the hedges may be coffee bushes, but such do not yield the best crop. The coffee plantation usually comes into bearing about the third year and lasts about forty years. After brewing coffee, people normally do is to throw out the coffee residues believing that there is nothing more to be obtained from using these residues. However, with a little research you will soon get to find out that coffee residues can be used as fertilizer. Coffee residues contain low levels of nitrogen as well as small amounts of calcium and magnesium, and traces of salt. Although fresh grains of coffee have high acidic levels, once they have been brewed the acidic levels become low, which makes them a good additive to alkaline soils. This study is conducted such that the researchers would want to determine if the coffee residues, if used as fertilizer, can help the onion chives grow. B. Significance of the...
