The document describes the results of a composting experiment over 5 weeks. Soil tests were conducted to analyze pH, nitrogen, phosphorus, and potassium levels. Gram staining was also performed to identify bacteria present. In the second week, the soil pH was adequate, nitrogen and phosphorus were deficient, and temperature was higher. Gram staining showed Bacillus and Coccus. In the third week, all nutrient levels were normal and temperature was lower; Gram staining showed Bacillus, Coccus, and Bacillus. By the fifth week, pH was high but nitrogen, phosphorus, and potassium were adequate; temperature was lower and Gram staining identified additional Bacillus.
