| The Nafferton factorial systems comparison (NFSC) experiments facilitate the investigation of effects of, and interaction between, three production system components - a) rotational position, b) fertility and c) crop protection management - in organic, conventional and low-input crop management systems. This paper presents first results on pesticide and growth regulator residues observed over a period of two years. Residues were only detected for three (Chlormequat, Chlorothalonil and Aldicarb) of the 28 pesticides used in the experiments. As expected, residue levels were affected by the crop protection practices, but significant effects of fertility management practices were also detected. This indicates that the human health risks associated with... |

| In addition to improved yields, the use of organic methods can benefit the nutritional value of foods in several ways, compared with subsistence agriculture, and in some respects also when compared with the use of high-input conventional farming methods. The recycling of organic matter retards depletion of the soil and ensures that increases in yield are not offset by mineral deficiencies caused by unbalanced plant nutrition. City populations can use organic products to minimize their intake of pesticide residues and nitrate. Improved nutritional status of crops under low-input conditions can increase the contents of protein and vitamin A, but can also increase the contents of some anti-nutrients. Improved availability of firewood through agroforestry... |
