π± Soil Erosion and Conservation
Soil erosion is when the top layer of soil is washed or blown away by running water π§ or strong wind π¬️.
π Wind and water take away fertile soil, leaving behind land that is poor and dry.
π§ Effects of Running Water on Soil
-
π¦ Running water forms gullies (deep cuts in the land)
-
πΎ Bare land on slopes loses soil faster than flat, covered land
-
π Soil is carried into rivers and dams, making them muddy
π¬️ Effects of Wind on Soil
-
πͺ️ Strong winds blow away dry soil
-
π«️ Dust storms can carry fertile soil far away
-
π΅ Wind erosion happens more when there are no plants covering the ground
π³ Causes of Soil Erosion
-
❌ Cutting down trees and grass
-
❌ Bush fires that burn plant cover
-
❌ Overstocking animals who eat all the grass
-
❌ Ploughing down the slope instead of across
-
❌ Leaving soil bare and uncovered
π Effects on Our Environment
-
π± Plants don’t grow well without fertile topsoil
-
π³️ Gullies and bare patches appear
-
π Animals suffer from lack of grass
-
π️ Rivers and dams fill with mud
π€Ί Soil Conservation: How to Protect Soil
Here’s how we can be soil savers! πͺπ
-
πΏ Plant grass and trees to hold the soil
-
πͺ΅ Use mulch (cut grass or dry leaves) to cover the soil
-
π Don’t let animals eat all the grass in one place
-
↔️ Plough across slopes, not down
-
π₯ Avoid burning grass and trees
