How to Farm with `Bio-logic´
An article recently appeared on news24.com discussing how pioneering viticulturalist Johnathan Grieve uses ducks, wasps and beetles instead of chemical pestisides on his farm Avondale.
He said: "I find that making use of these natural predators works much more effectively, and is a lot cheaper.He has also cut back on fertilisers by planting legumes and cereals as "cover crops" among the vines to provide natural compost and bind nitrogen from the air into the soil. The plants also suppress weeds and keep the soil moist.
