Factors that influence Agricultural activities
Different crops for example require varying limits of rainfall, humidity and temperature.
Temperature affects crops maturity, ripening of fruits and determines soil moisture content as well as influences the rate of photosynthesis and transpiration.
Crops such as cocoa, oil palm require high relative humidity.
Crops like tea, coffee do well in higher altitude about 1525m while rice, cotton, sugarcane require lower altitudes.
Lowland eases cultivation and mechanization of agriculture.
Different crops require different types of soil in terms of mineral composition and drainage.
The presence of and/ or absence of parasitic plants, insect pests and disease largely influence the type of agriculture.
The type of farming practiced depends on the culture of the farmers concerned e.g. Systems of land ownership and inheritance have led to uneconomical subdivision of land limiting extensive farming.
Religion e.g. pigs not kept /eaten by Muslims, Hindus and Jews
Traditional diet – some crops are traditionally grown e.g. bananas
–Uganda, yams –Nigeria.
Certain cultures limit use of modern technology in farming.
Such as operational costs of agriculture, marketing expenses, price fluctuations, government policy (subsidies), and international agreements on a quota system.
