Here is a very crude demonstration of how 2 different types of soil structures respond to downpour.
Sample I is a humus rich annual vegetable garden bed. It is a no till bed. The video was recorded just before we added mulch to the bed. It resembles with a mature forest floor rich in organic matter.
Sample II is a pathway between the beds. It had topsoil removed & is compacted because of regular foot traffic. It resembles a piece of land with topsoil eroded.
It is evident that the soil is acting like a sponge. No water run-off.
No water absorption. Water runoff is evident.
Sample I, rich in humus & organic matter, has better water absorption capacity. The soils with this kind of structure provide multiple benefits.
- It can store large amount of water. Also, helps recharge acquifers.
- Minimal water evaporation & better moisture retention capability reduce irrigation needs.
- The organic matter & porosity provide more surface area, food, moisture & needed aeration for beneficial microbes & earthworms. It is like a 5-star hotel for the life below.
- Plant roots find it easier to go deeper to absorb nutrients and minerals.
