Question

What enahances the water holdiing capacity of soil​

Answer 1

Answer:

The addition of organic matter to the soil usually increases the water holding capacity of the soil. ... Soil water is held by adhesive and cohesive forces within the soil and an increase in pore space will lead to an increase in water holding capacity of the soil.

Answer 2

Answer:

Increase in the percentage of soil organic matter

Explanation:

• Simply defined, soil water holding capacity is the amount of water 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 entire field.
• Soil texture and organic matter are the key components that determine soil water holding capacity.
• In terms of soil texture, those made up of smaller particle sizes, such as in the case of silt and clay, have larger surface area. The larger the surface area the easier it is for the soil to hold onto water so it has a higher water holding capacity.
• Soil organic matter (SOM) is another factor that can help increase water holding capacity. Soil organic matter has a natural magnetism to water. If the farm increases the percentage of soil organic matter, the soil water holding capacity will increase.
• Here are some basic ways that a farm can increase their SOM :

1. Use cover crops;
2. Change to conservation-tillage practices, for example no-till or minimal tillage;
3. Add manure;
4. Add compost.
