Choice of crops
Each crop and crop variety has its own specific needs. In some places it will
grow well and others it will not. Crops are affected by;
• soil type
• rainfall
• altitude
• temperature
• the type and amount of nutrients required
• the amount of water needed
These factors affect how a crop grows and yields. If a crop is grown in a
climate to which it is not suited, it is likely to produce low yields and be more
susceptible to pest and diseases. This then creates the need to use agrochemicals
to fertilise the crop and control pest and diseases.
The successful organic farmer learns to grow the crops and varieties which are
suited to the local conditions. He should grow crops which are suited to his
geography and climate. He should choose varieties which are suited to the local
conditions such as local varieties.
