The first is labelled as Valley A‚ and was obtained from a field which has been known to be uncultivated for 10 years in the valley. Valley B was obtained from a domestic garden‚ under a Magnolia tree in the same region. At times when a third sample was tested‚ the source will be indicated. Soil texture

Soil Porosity & Density Objective: To determine if the porosity of soil is related to the density. Hypothesis: I think that that the porosity of soil is related to the density because the higher the density of the sand the lower the porosity of the sand‚ which are both componets for the water to rise. Materials: • Sand and Loam samples • 2 large containers • Plastic cups • Water • Scale Procedure: Loam 1) The loam without the water was fresh ‚ it had different shades of black‚ and

Human’s activities such as deforestation‚ farming‚ over grazing and development result the soil compaction‚ erosion‚ desertification‚ and alteration of local climatic conditions. These changes make the wildlife ill-adapt to the drastically changed environment. In areas where rare species are present‚ habitat destruction can quickly force a species
