Case Study 13. Increase of soil biodiversity through amendment of forest based organic material in potato crops. Boreal (Finland).
Which problem will be solved: Potato cultivation has the risk to loose soil organic carbon due to deep ploughing and irrigation. Addition of forest based organic products adds carbon to soil.
State of the art: Potato cultivation in the boreal area is intensive using deep ploughing, irrigation and mineral fertilization. Eutrophication risk of nearby waters/ground water is high.
Objective: The objective is to test if forest based carbon addition increases soil biodiversity and carbon stocks in the soil.
Proposed management practices: We will compare potato harvest, compare microbiome diversity, carbon storage and disease occurrence between treatments in relation to forest based carbon addition
Progress with the case study in relation with the state of the art: Finding adequate forest based material addition is the first step of a new fertilization improving biodiversity and carbon storage of soil
