Soil:

The soil along with its physical and Chemical characteristics has important effects on crops, as the minerals it Contains provide nutrients needed by plants. The most important characteristics Are depth as deep soils with well-developed layers are usually more fertile than Shallow soils; texture or particle size and composition, as these influence the Soil´s capacity to retain water; porosity, to be able to let air reaches Plants´ roots; and acidity and alkalinity since very acid or alkaline soils are Toxic for plants.
