Factors such as soil texture and precipitation control the amount of water available to plants Although water requirements vary by species, the amount of water a flower absorbs is greatly ....
This is because water will not go excessively deep (as in a sand), and the plant available water amount is high These soils also have about 50% of the soil water present available for root uptake (4) Heavy textured soils (clay loams, clay) hold the greatest amount of water (if it is capable of absorbing it)...

Water quality is one of the most important factors affecting plant growth, as unwanted , the best option to reduce the amount of salts in the water , causing sodium to become the dominant ion in the water This leads to a lack of available calcium and magnesium to the plant and interferes with water uptake by ,...
Environmental Factors Light, water, temperature, humidity, ventilation, fertilization, and soil are chief factors affecting plant growth, and any one of these factors in incorrect proportions will prevent proper plant growth indoors Light Light is probably the most essential factor for house plant growth The growth of plants and the...
Nov 06, 2019· The amount of water that plants transpire varies greatly geographically and over time There are a number of factors that determine transpiration rates: Temperature : Transpiration rates go up as the temperature goes up, especially during the growing season, when the air is warmer due to stronger sunlight and warmer air mass...
