The newspaper El Español has reported on the alliance between Carboliva and the Seville-based cooperative Arbequisur to promote the use of biochar and compost in new super-intensive olive plantations.
Members of the cooperative will be able to apply, at no cost to their new plantations, a mixture consisting of one-third olive pulp biochar, produced by Carboliva, and two-thirds alpeorujo compost produced by Arbequisur and certified for organic farming. The trial involves approximately 3,000 kilos per hectare and will leave one or two lines of olive trees untreated as a control, to compare vigour and growth rate from the first year.
The objective is to verify in the field how this combination performs, its effect on soil regeneration, and its contribution to the initial development of young olive trees. The initiative aligns with the new National Fertiliser Plan, which aims to diversify nutrient sources using organic materials.
Arbequisur is a cooperative from Aguadulce (Seville) integrated into Oleoestepa. For both parties, the alliance demonstrates that olive grove by-products can return to the grove itself, converted into valuable agronomic solutions.
