P = ET + SS + D - 2Soil AerationSoil macroporosity (as affected by texture and structure)
Soil water content (as it affects water/air ratio)
Oxygen consumption by respiration (Including plant roots and microorganisms) - 3Hydrophytesare plants that have ways of obtaining oxygen in waterlogged soils
- 4AerenchymaSome grasses use aerenchyma tissues to transport oxygen down the stem to the roots
- 5Atmospheric concentrations78% Nitrogen (N2)
21% Oxygen (O2)
0.035% Carbon Dioxide (CO2) - 6Soil TemperatureCold temperatures slow chemical reactions
Cold temperatures slow biological decomposition - 7soil temperatureWarm soil temperatures generally induce plant germination and growth
Seeds of plants that are adapted to open gaps react to warm soil temperatures caused by direct solar radiation
Seeds of prairie grasses require a cold period to enable them to germinate. This is called vernalization.
