Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that, together, support life. Earth's body of soil (the pedosphere) functions as a medium for plant growth; as a means of water storage, supply, and purification; as a habitat for organisms; and as a modifier of the planet's atmosphere.

On a much smaller scale, soil is still crucial for simple agricultural crop production and residential gardening. There are all kinds of different kinds of soil. For instance, in Texas, there are 60 different soil types found throughout the state.

Here are some of the most popular types of soil and when to utilize each of them:

  • Clay -- Clay is one of the smallest of all natural soil particles, and can be packed tightly together with little air space. Not only is clay one of the smallest types of soil, it's also the heaviest and densest type, enabling it to retain large amounts of water and nutrients. Whenever gardening in clay soil, you should work under certain conditions. Try planting in spring never using clay and add mulch during colder months.

  • Chalk -- Commonly known as calcareous soil, chalk is found over limestone beds and deep underground. This is a very adhesive type of soil and is difficult to work with when wet. If you're gardening with chalk and want to make it more plant-friendly, consider adding acid-rich materials like compost or manure to help neutralize the soil and reduce lime content by improving water absorption.

  • Sand -- Sandy soil consists of quartz, silica, and other rocks. It has a very rough texture that leads to the formation of air pockets within the soil. Keep in mind, sand doesn't hold moisture all that well, so it can be difficult for plants to access the necessary nutrients before they are washed away. Try adding small amounts of organic materials to combat the quick-draining properties of the sand.

Identifying the type of soil you need for a gardening project is essential in order to support the healthy growth of all your plants. It's also important to take into account when watering your lawn -- one inch may be optimal for some soil, but not for other types. Knowing your soil can lead to a healthier, more beautiful lawn all around.
