the atmosphere through cellular respiration and can then be used by plants during photosynthesis. Decomposition is when carbon dioxide is given off when organisms die.

Method of test 1: 1. Use a spade to dig a hole 4 inches deep. 2. Break up the soil within the hole and remove any twigs,

describes soils that contain high concentrations of water-soluble salts, mainly NaCl. Salinity is usually caused by two mechanisms: groundwater salinity and irrigation salinity.

Irrigation salinity occurs when irrigation water accumulates in the upper layers of soil. When
