How is soil valuable for us?
Why is soil important? Healthy soils are essential for healthy plant growth, human nutrition, and water filtration. Soil helps to regulate the Earth’s climate and stores more carbon than all of the world’s forests combined. Healthy soils are fundamental to our survival.
Is a tree a living thing?
Trees, bushes, a cactus, flowers and grass are examples of plants. Plants are also living things. Plants are living because they grow, take in nutrients and reproduce. Trees, bushes, a cactus, flowers and grass are examples of plants.

Why does soil lose its fertility?
Soil fertility decline occurs when the quantities of nutrients removed from the soil in harvested products exceed the quantities of nutrients being applied. In this situation, the nutrient requirements of the crop are met from soil reserves until these reserves cannot meet crop demands.
What are 3 benefits of soil?
It provides an environment for plants (including food crops and timber wood) to grow in, by anchoring roots and storing nutrients. It filters and cleans our water and helps prevent natural hazards such as flooding. It contains immense levels of biodiversity.
