No período de 1997 a 1999 ensaiaram-se três modalidades de manutenção da superfície do solo em olival, designadamente: mobilização tradicional; não mobilização, com recurso a herbicidas; e uma sideração de tremoço branco. Os ensaios decorreram na Terra Quente Transmontana, próximo de Mirandela. Avaliaram-se as modificações ocorridas no solo e no estado nutritivo das plantas e determinou-se a produção de azeitona. A maior parte das metodologias não permitiu detectar diferenças significativas entre tratamentos. Contudo, quando o efeito dos tratamentos foi avaliado pela produção de azeitona, o sistema de não mobilização apresentou resultados estatisticamente superiores. Trabalho financiado no âmbito do Projecto PAMAF 2043.
During 1997-1999 period three soil maintenance systems were imposed on an olive grove near Mirandela (Northeast Portugal). The treatments were: conventional tillage; no-tillage (only herbicides); and Lupinus albus as green manure. The treatments effect was compared by soil and plant analysis and olive yield. Soil analysis indicated a slight increase in organic matter on no-tillage system, while soil phosphorus and nitrogen availability were improved by green manure. There was no significant effect of treatments on nutritional status of trees. Regarding olive yield there was significant differences among treatments. No-tillage originated the greatest values.
