the humus lab were were trying to find out if hydrogen peroxide would cause a reaction and show us the amount of humus in the soil by putting gas into a graduated cylinder with water to make the water level lower therefore showing us how much humus the material being tested contained. It showed that the sand was lacking humus but the mushroom compost was the most rich in humus. My hypothesis was correct because I predicted that the mushroom compost would produce the greatest amount of humus out

like plastics‚ rubber. even we must take the initiative of awaring others that plastics like plastic bags must be reused. Composting is a biological process in which micro-organisms‚ mainly fungi and bacteria‚ convert degradable organic waste into humus like substance. This finished product is high in carbon and nitrogen and is an excellent medium for growing plants. The process of composting ensures the waste that is produced in the kitchens is not carelessly thrown and left to rot be a home for

Among the soil fauna‚ earthworms have an important role to improve soil texture. The soil texture plays an important role in water holding capacity. Earthworms have an ability to enhance soil characteristics. It contributes to the breakdown of organic matter and release plant nutrients (Edwards and Bohlen‚ 1996). Earthworms are also considered as useful indicator of the health of soil ecosystem (Edwards and Bohlen‚ 1992) as to their role in soil fertility through fragmentation and mixed up the soil

Soil properties: Some physical and chemical properties of the soil were measured‚ which are presented in Table 1. The availability of nutrients and even contaminants depends on the degree of soil acidity. The most suitable pH for soil microorganism’ activity is 7‚ as nutrient solubility depends on soil pH changes (Riser-Roberts‚ 1998). The soil used in the present study has neutral pH and therefore does not limit the activity of microorganisms or the solubility of nutrients except for phosphorus

This experiment was very eye-opening as it allowed me to observe the struggles and patience that the farmer faces when growing these crops. The first few days of the experiment proved to be rather slow as very little growth could be observed. After the several days of being under the scorching sun the leaves of the tomato plants started to dry up and would fall off at the very touch of it. More water had to be added to them to further hydrate the plants. It was only after around 30 days that a concrete
