| The aim of the work is to evaluate on a long term perspective the effect of application of different organic fertilizers on tree nutritional status, yield, fruits quality and soil fertility in a orange [Citrus sinensis (L.) Osbeck, cv. ‘Valencia late’], grafted on C. aurantium (L.) orchard cultivated on sandy loam soil, sized 1.8 hectars and located in Eastern Sicily. In a randomized block experimental design with three replicates (60 trees each plot), four treatments are compared. Treatments 1 and 2 receive two different composts; treatment 3 is fertilized using dried poultry manure and the control treatment is treated by mineral/synthetic fertilizers. Every year, each plot receives the same amount of total N, matching the needs of the crop.... |

| The overall aims of organic and low input crop production include the economically viable and environmentally sound production of high quality food and feed. Technological bottlenecks in such systems include insufficient and instable yields and in some instances unsatisfactory processing, sensory and/or nutritional quality of the final product. Recently, concerns have also been raised that the intensive use of manures may lead to increased risk for contamination of food by enteropathogenic micro-organisms. Crop production in low input systems is based on key pillars, i.e. (i) a fertile soil which provides sufficient capacity to allow for plant growth while preventing soil-borne diseases, (ii) high quality, disease-free seeds and plant material, (iii) a... |
