Opposite of abiotic (environmental) factors. Non-biological environmental factors that affect plant growth and development in a specific ecosystem. Abiotic factors influence the (micro-)climate that plants experience. Examples of abiotic factors: Soil properties (texture, salinity, acidity) Water properties (rainfall, irrigation, pH) Air properties (humidity, wind) Temperature (seasonality, daily variation, minimum, average, maximum) Sunlight properties (light quantity, light quality, daylength)
OT: abiotic factors ↔ biotic factors
