INTENSIVE farmers spray chemical fertilisers directly on to their crops usually by using a spraying tractor. This helps the crops grow by giving them all the nutrients they need but these are artificial. ORGANIC farming actually uses the natural process that nature has harnessed over millions of years where the soil itself carries all the neccesary nutrients and food the plants need, ready for it to be sucked up in to the plant as and when it needs it. Insects underground are always working on making the soil good through the natural nitrogen cycle. By using a process called CROP ROTATION, the farmer can keep a good soil for many years without resorting to chemicals. Instead he uses manure, kitchen waste and compost.
