Abiotic facotrs are the non-living components of the ecosystem. The chemical, geological factors like soil, minerals, rocks and physical factors like temperature, wind, water, sunlight are defined as abiotic factors. The abiotic factors effect the ecosystem and play a vital role in the biology of the ecosystem. The abiotic facts factores also include light, acidity, radiation, humidity, temperature and all organic and inorganic components of the ecosystem. The quantity of the abiotic components present in the ecosystem is known as 'the standing stage'. The biotic components of the ecosystem which includes the plants, animals and microbes interact and are dependent on the abitoic factors.

The list of abiotic factors are

clouds,
weather,
latitude,
temperature,
oxygen,
salinity,
soil (edaphic factors),
air,
water,
sunlight,
humidity,
topography,
pH,
atmospheric gases.

Let us read through the list of the abiotic factors and how these factors affect the ecosystem and the interactions of these factors with the biotic factors.

Soil - Edaphic Factors

The edaphic factors are the abiotic factors with respect to soil. These factors include

Soil texture - The texture of the soil is variable from particles like clay to larger particles like sand. Sandy soils are suitablke for growing plants and are well aerated and are easy to cultivate. Sandy soils cannot retain much water and contain few nutrients required for plant growth.

Soil air - Soil air is the spaces between the soil particles where it is not filled with soil water. The soil air determines the firmness of the soil.

Temperature of soil - Temperature of the soil is an important factor, temperature of soil below 30cm is said to be constant but there are seasonal variations. The decaying caused by decay-causing microorganisms is low at lower temperature.

Soil water - Soil water is classified into three types - capillary water, hygroscopic water and gravitational water.

Soil pH - pH of the soil affects the biological activity in the soil and certain mineral availability. The pH influences the growth and development
