Soil Organic Matter Determination (Practical)

Organic Matter Soil organic matter (SOM) represents the remains of roots, plant material, and soil organisms in various stages of decomposition and synthesis, and is variable in composition. Though occurring in relatively small amounts in soils, organic matter (OM) has…

Soil pH Determination (Practical)

pH Soil hydrogen ion concentration may be a crucial soil indicator, and is outlined because the negative log of the cation activity. Since hydrogen ion concentration is index, the H-ion concentration in resolution will increase 10 times once its hydrogen ion concentration is lowered by one unit. The hydrogen ion concentration vary usually found in soils varies from three to nine. numerous classes of soil hydrogen ion concentration is also at random delineated as follows: – powerfully acid…
