COMESE, Romina V; GONZALEZ, Mirta G  e  CONTI, Marta E. Changes in horticultural soil properties and yield responses of Beta Vulgaris var. Cicla (l) to organic amendment applications. Cienc. suelo [online]. 2009, vol.27, n.2, pp.271-275. ISSN 1850-2067.

A sustainable approach to dealing with waste generated in agriculture is its application in horticultural production. The aim of this study was to evaluate the effect of applying different types and quantities of organic amendments, compostvermicompost (LC) and bone meal (HH), in the production of beet and its impact on soil physical and chemical properties. The experiment was conducted in the urban organic vegetable garden at the Facultad de Agronomía-UBA (FAUBA) in a Typical Argiudoll. Soil organic carbon (CO), particulate organic carbon (COP), bulk density (DA), extractable phosphorus (Pe), pH, electrical conductivity (EC) and cation exchange capacity (CEC) were evaluated. Dry matter yield (DM) and nutrients in dry matter (mg NPK kg MS-1) were determined on beet. The results showed some differences in edaphic variables, yield and nutrient content in plant dry matter. In the soil, COP, CIC, EP and EC were increased with LC and LC HH. Vermicompost and bone meal combined and applied at double rates proved to be the best amendment for the maintenance of soil properties and beet productivity.
