Three factors affecting the distribution of pasture are:
a) Rainfall: the amount of rainfall determines the nature of the pasture. Optimum rainfall favors luxuriant growth of pasture while little or no rainfall prevents the growth of pasture.
b) Soil type: the type of soil determines the rate of growth of soil. Some soils tend to favor pasture growth (e.g loamy soil) than others.
c) Pest and disease: High incidence of pest and diseases in an area tends to reduce the quality and quantity of pasture.
