Does black soil holds more water?

Does black soil holds more water?

The black soil is very deep. In the dry season, this soil will form cracks. To cope with slow absorption rates and excess loss of moisture, the black soil tends to retain the moisture for a very long time, which increases the crops during summer times or dry season. Hence, the correct answer is option (C).

What soil holds most water?

Generally speaking, clay-rich soils have the largest pore space, hence the greatest total water holding capacity.

How do you reduce water retention in soil?

Use coarse-textured fill material, such as sandy loam or loamy sand, to improve aeration and drainage. Do not use soil with a high clay content as fill material. Soil conditions that should be avoided include gravel under loam and sand on top of clay.

Why does black soil retain moisture?

The clay of the black soil has an ability to expand and contract. When the soil comes in contact with water when the field is irrigated, the clay present in the soil absorbs the water and the moisture content available. Therefore, black soil has a great capacity to hold moisture.

Is black soil found in heavy rainfall areas?

Black soils are derivatives of trap lava and are spread mostly across interior Gujarat, Maharashtra, Karnataka, and Madhya Pradesh on the Deccan lava plateau and the Malwa Plateau, where there is both moderate rainfall and underlying basaltic rock.

Which soil Cannot retain water?

Sandy soil has a larger particle size; it cannot hold much water and needs frequent smaller doses of water. Silt has smaller particles; its water-holding capacity is ideal for most plants.

What would harm soil the most?

Overuse of pesticides or herbicides is the primary culprit. Sometimes chemically treated wood is used in landscaping. If not used properly, this can contaminate the soil as well as the plant and microbial life it sustains. Also, overuse of winter salt can harm your soils.

How do you fix waterlogged clay soil?

Strategies for Dealing with Water Logged Soils

  1. Plant Cover Crops. Cover crops are an excellent way to use excess water.
  2. Go No-Till. A more long term strategy, going no -till improves soil structure to help with drainage.
  3. Add Organic Material.
  4. Subsoil.
  5. Build Raised Beds.
  6. A Note About Sand.

What happens when there is too much water in soil?

Too much water actually is bad for most of our trees and plants. If soil becomes waterlogged and stays that way — as poorly draining clay soil tends to do — the water can cut off the air supply to the roots and to the microorganisms that live in healthy soil. It can lead to root rot or other diseases.

Which soil retain moisture for a long time?

Loamy soil is a blend of composition of clay, silt and sands, which holds the maximum moisture for long period of time. Alluvial Soil considered as the most fertile soil next to loamy soil. This type of soil also contains sand, silt and clay and the clay soil also retains the moisture for maximum amount of time.

How does the water retention curve affect soil?

The soil water retention curve can also be influenced by whether the soil is undergoing wetting (sorption) or drying (desorption). When the soil water retention curve differs between wetting and drying, that phenomenon is called hysteresis.

How is water retention related to pores in soil?

Water retention in soil can be understood as the water retained by the soil after it runs through the soil pores to join water bodies such as groundwater or surface streams. Pores in the soil can be defined as the air-spaces that exist in between soil particles. Water retention is mainly dependant on the particle size of the soil.

What is the water retention curve for silt loam?

Water retention curves for samples of a silt loam soil at different levels of compaction indicated by the bulk density values ranging from 1.01 to 1.34 g cm-3. Adapted from Stange and Horne (2005).

How does air entrapment affect soil water retention?

Soil chemical, physical, and biological processes can alter the amount and distribution of entrapped air over time, so the impact of air-entrapment on soil water retention can change with each subsequent re-wetting cycle. Fig. 3‑9.
