The pros and cons of drip irrigation

Drip irrigation saves water and electricity, but is not suitable for all crop types. So make sure you end up with the right system, says Bill Kerr.

Putting crop rotation into perspective

When developing a crop rotation programme, one must take into consideration the various pests and diseases that may infect different crops in order to avoid disastrous results, says Bill Kerr.
