DOMINO – Synthesis of Soil Management Strategies Integrating Plant and Waste Based Alternative Fertilizers

Summary in the original language of the document

The project DOMINO (http://www.domino-coreorganic.eu/) focused on the evaluation of alternative fertilisers based on locally available wastes, legume-based materials and vermicompost extracts as alternatives to animal-based fertilizers from conventional agriculture in apple orchards. The project included incubation experiments, pot and field experiments in different European countries. In addition, a survey on nutrient budgets and soil nutrient status in organic fruit orchards was conducted in Germany. The evaluation of the fertilizers encompassed also their impact on soil nematodes and microbial activity and biodiversity. Considering all pros and cons, there is no single ideal solution for fertilization.
An integrated approach using fertilizers based on legumes in combination with stillages that provide N early in the season can enhance farm internal N cycles leading to an overall higher N efficiency.
