Roots act like straws absorbing water and minerals from the soil. Tiny root hairs stick out of the root, helping in the absorption. Roots help to anchor the plant in the soil so it does not fall over. Roots also store extra food for future use.

['Mineral. The largest component of soil is the mineral portion, which makes up approximately 45% to 49% of the volume. ... ', 'Water. Water is the second basic component of soil. ... ', 'Organic matter. Organic matter is the next basic component that is found in soils at levels of approximately 1% to 5%. ... ', 'Gases. ... ', 'Microorganisms.']

Additives like calcium and magnesium, found in Agricultural Lime, are required to rebalance the soil's structure. This also improves water penetration and facilitates the intake of major nutrients such as nitrogen, phosphorus and potassium.

All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil's properties – its texture, structure, porosity, chemistry and colour. Soil is made up of different-sized particles.

Soil makes up the top surface of the land surface. Aka, the weathered material (sand, silt, clay and organic material) above the rock layer. So soil makes up land, and can be used to grow crops, build buildings on, filter water, store nutrients, etc.

They may supply food, wood, firewood, forage and nitrogen to the soil providing habitat, shade or soil improvement. In most cases multipurpose trees and shrubs have a primary role such as being part of a living fence, a windbreak, or used in an ally cropping system.

Organic materials and fertilizers improve the soil texture, allowing it to hold water longer, and increase the bacterial and fungal activity in the soil. So, they not only assist your plants, they help the soil. Synthetic fertilizers, on the other hand, deplete the soil of its nutrients, making it unproductive.

Enzymes, in turn, catalyse important biochemical reactions for rhizobacteria and plants, stabilize the soil by degrading wastes and mediate nutrient recycling [1]. The available enzymes inside soil could originate from plants, animals or microbes (bacteria or fungi).

Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
