The application of organic residues to soil is widely developed during last years. In particular, green compost represents a good amendant with a low environmental impact and it can improve the quality of fruits and vegetables through an increase of sugars and organic acids. This aspect is extremely important because the modern consumer puts more attention to the healthy and nutritional properties of food. The aim of this research was to evaluate the effects of green compost used as soil amendment on phenols and vitamin C content and on antioxidant capacity. So plants of Lactuca sativa var. acephala cultivar Red Salad Bowl and Spinacia oleracea cultivar Lorelay were grown on three soil treatments: a) 100% soil, b) 75% soil plus 25% compost c) 50% soil plus 50% compost. Results show that adding green compost to soil improves its fertility and the plant’s growth. However the healthy properties of spinach decrease in function of the compost concentration in soil.

Abstract
The application of organic residues to soil is widely developed during last years. In particular, green compost represents a good amendant with a low environmental impact and it can improve the quality of fruits and vegetables through an increase of sugars and organic acids. This aspect is extremely important because the modern consumer puts more attention to the healthy and nutritional properties of food. The aim of this research was to evaluate the effects of green compost used as soil amendment on phenols and vitamin C content and on antioxidant capacity. So plants of Lactuca sativa var. acephala cultivar Red Salad Bowl and Spinacia oleracea cultivar Lorelay were grown on three soil treatments: a) 100% soil, b) 75% soil plus 25% compost c) 50% soil plus 50% compost. Results show that adding green compost to soil improves its fertility and the plant’s growth. However the healthy properties of spinach decrease in function of the compost concentration in soil.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
