AB The main objective of this study was to compare the performance of two liquid organic fertilizers,an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. Thesource of the fertilizer (mineral or organic) had significant effect in the nutritional status ofthe organic and conventionally managed mandarins. Nutrient uptake, vegetative growth,carbohydrate synthesis and soil characteristics were analyzed. Results showed that plantsfertilized with animal based liquid fertilizers exhibited higher total biomass with a more profusedevelopment of new developing organs (leaves and fibrous roots). Liquid organic fertilizationresulted in an increased uptake of macro and micronutrients compared to mineralfertilized trees. Moreover, organic fertilization positively affected the carbohydrate content(fructose, glucose and sucrose) mainly in summer flush leaves. Liquid organic fertilizationalso resulted in an increase of soil organic matter content. Animal-based fertilizer, due tointrinsic composition, increased total tree biomass and carbohydrate leaves content, andled to lower soil nitrate concentration and higher P and Mg exchangeable in soil extractcompared to vegetal-based fertilizer. Therefore, liquid organic fertilizers could be used asan alternative to traditional mineral fertilization in drip irrigated citrus trees.
