Soil is important to plants because it stores nutrients and serves as a medium for growth. It is an anchor for roots and also holds water needed by plants for moisture. Soil contains the air, water and food that provides a suitable place for plants to grow.Continue Reading
The properties of soil that affect plant growth include texture, aeration (i.e., permeability), porosity, water holding capacity and aggregate size.
A vital function of soil is storing and supplying minerals and nutrients essential for plant life. This is referred to as soil fertility. The proportions of clay and organic matter found in soil influence its fertility.
As a regulator and collector of water, soil absorbs and stores moisture for plants and organisms to use. It also shelters plants against extreme temperatures and protects roots from direct sunlight. Moreover, living organisms of various sizes thrive in soil. There are microorganisms and insects in soil that improve it, allowing plants to grow better. These tiny microorganisms, such as fungi and bacteria, decompose the soil and transform old, dead materials into raw materials that plants need for growth.
The quality of soil is important for the health of plants and the humans and animals that consume plants.Learn more about Soil
Soil is important because it provides the nutrients that plants need to grow. When a plant grows, it feeds the animals that consume them, which in turn, feed humans. Soil also filters fresh water as it travels through underwater rivers called aquifers.Full Answer >
Earthworms provide many positive benefits to improve plant growth, including aerating the soil, improving drainage and providing nutrients the plants need. They help to turn the soil and bring mix organic materials from the surface so the forces of nature can break down these products to further enrich the soil.Full Answer >
The growth of bacteria is affected by water, oxygen, nutrients, temperature and the medium's acidity. Bacteria are single-celled organisms found in water, air and on solid surfaces. Bacterial growth refers to the bacteria increasing in numbers of cells, rather than size.Full Answer >
Darcy's law is a constitutive equation that explains how fluids are able to flow through a porous medium, such as a rock or sand. This law can be used to describe how water flows through aquifers and reservoirs.Full Answer >
