The importance of soil 150 words (3 paragraph)
Answers
Answer:
Soil is loose material which lies on top of the land. It has many things in it, like tiny grains of rock, minerals, water and air. Soil also has living things and dead things in it: "organic matter". Soil is important for life on Earth.
Because soil holds water and nutrients, it is an ideal place for plants to grow.[1] Soil holds the roots, and lets plants stand above the ground to collect the light they need to live. Almost as important are the fungi. There are fungi which grow into plant roots, a symbiosis known as mycorrhiza. This helps trees grow. There are many other fungi that live by breaking down dead organic material: the remains of other living things. The broken down material is a main source of plant nutrients.[2]
Many animals dig into the soil and make the soil their home. The large animals use soil to make dens for sleeping and giving birth. The small animals live most of their life in the soil. Earthworms are famous for improving soil. This is because the holes they make let air go into the soil. The holes also let water go through.
The soil also has many microorganisms living in it. Many of them eat the organic material in the soil. They use oxygen and release carbon dioxide. They also release mineral nutrients into the soil.[3]
Soil is different in different places on Earth. This is because the climate and rocks in the Earth are different in different places on Earth. Soils are usually thicker in places where ice sheets covered the ground during the Pleistocene ice ages. This is because the ice sheets ground the rock into powder as they slowly moved over the surface.

Why is soil important?
Healthy soils are essential for healthy plant growth, human nutrition, and water filtration. Healthy soil supports a landscape that is more resilient to the impacts of drought, flood, or fire. 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.
What is a soil test?
A soil test is an easy and inexpensive way to determine your soil’s level of nutrients, pH, and organic matter. Testing your soil is an essential step for a natural approach to lawn care. There is no way to know what your lawn needs without one!
Why should I test my soil?
Healthy soil is the key to having a lush, green lawn. It is impossible to know what your soil needs without doing a soil test. Levels of pH, nutrients, and organic matter all impact plant growth.
A soil test will save you time and money by showing you what your soil needs.
