Soils that hold generous amounts of water are less subject to leaching losses of nutrients or soil applied pesticides. This is true because a soil with a limited water holding capacity (i.e. a sandy loam) reaches the saturation point much sooner than a soil with a higher water holding capacity (i.e. a clay loam).

Secondly, use Figure 3 to calculate the water holding capacity of each soil layer in the root zone. For example, 25cm of clay loam with an available water of 1.8mm water per cm of soil, can store 45mm of available water. The water holding capacity of a soil is calculated by summing the capacity of each layer in the root zone.

How to know the available water holding capacity of clay soil? I'm developing a model for irrigation water scheduling and the soil texture of study area is clay but it varies from one region to ...

Soil water holding capacity is a term that all farms should know to optimize crop production. Simply defined soil water holding capacity is the amount of water that a given soil can hold for crop use. Field capacity is the point where the soil water holding capacity has reached its maximum for the ...

Clay type, organic content, and soil structure also influence soil water retention. The maximum amount of water that a given soil can retain is called field capacity, whereas a soil so dry that plants cannot liberate the remaining moisture from the soil particles is said to be at wilting point.

For example, 25cm of clay loam with an available water of 1.8mm water per cm of soil, can store 45mm of available water. The water holding capacity of a soil is calculated by summing the capacity of each layer in the root zone. &nbsp Source: Better Soils [Online]. 1997. Module 2: Soil Nutrition and Crops.

en.wikipedia.org/wiki/Field_capacity

Field Capacity is the amount of soil moisture or water content held in the soil after excess water has drained away and the rate of downward movement has decreased. This usually takes place 2–3 days after rain or irrigation in pervious soils of uniform structure and texture.

The volumetric soil moisture content at the wilting point will have dropped to around 5 to 10% for sandy soils, 10 to 15% in loam soils, and 15 to 20% in clay soils. Available Water Capacity. The total available water (holding) capacity is the portion of water that can be absorbed by plant roots. By definition it is the amount of water ...

Plant available water is that portion of the water holding capacity that can be absorbed by a plant. As a general rule, plant available water is considered to be 50 percent of the water holding capacity. The volumetric water content measured is the total amount of water held in a given soil volume at a given time.
