Soil quality is a major determinant, along with climate, of plant distribution and growth. Soil quality depends not only on the chemical composition of the soil, but also the topography (regional surface features) and the presence of living organisms. In agriculture, the history of the soil, such as the cultivating practices and previous crops, modify the characteristics and fertility of that soil.

Seeds must germinate under the right conditions in the soil; therefore, temperature, moisture, and soil quality are important factors that play a role in germination and seedling development. Soil quality and climate are significant to plant distribution and growth.

Soils consist of organic material, inorganic material, water and air, and they differ in proportions of clay, silt, and sand. A soil profile is characterized by horizontal layers called horizons. Climate, organisms, topography, parent material, and time influence soil composition and formation.

In agriculture and horticulture, soil generally refers to the medium for plant growth, typically material within the upper meter or two. Soil consists predominantly of mineral matter, but also contains organic matter (humus) and living organisms. The pore spaces between mineral grains are filled with varying proportions of water and air.

Through their roots, plants absorb water and minerals (e.g., nitrates, phosphates, potassium, copper, zinc). With these, they use photosynthesis to convert carbon dioxide (taken in through their leaves) into carbohydrates, proteins, lipids, nucleic acids and the vitamins on which all heterotrophs depend. Along with temperature and water, soil is a major determinant of productivity.
