Loam encompasses a variety of soil types, some granulated and nicely draining, while others may be thicker and have the consistency of mud. Most loam soils are a brown or black colour, making them ideal for gardens.

It is often the most preferred type for plant growth and does well with just about any species. Large plants and trees, including maples and poplars, are both commonly found growing in loam soil. Loam is a combination of small rock particles, organic matter and nutrients, often in ideal combinations for healthy plant growth.

In arid zones, the harsh conditions of climate and the shortage of water are intensified by the strong winds. Living conditions and agricultural production can often be improved by planting trees and shrubs in protective windbreaks and shelterbelts which reduce wind velocity and provide shade.

Windbreaks and shelterbelts, which are considered synonymous in this manual, are barriers of trees or shrubs that are planted to reduce wind velocities and, as a result, reduce evapotranspiration and prevent wind erosion; they frequently provide direct benefits to agricultural crops, resulting in higher yields, and provide shelter to livestock, grazing lands, and farms.
