Description

Main research question/goal

The primary goal of SUBTECH is to develop environmental friendly solutions for future plant production in wood-fibre-based substrates. SUBTECH facilitates more sustainable and resource efficient production systems for the horticultural industry. New growing media based on wood fibres reduce peat extraction and the related greenhouse gas emissions from peatlands and stimulate the use of renewable (forestry) resources in agriculture. Precise fertigation based on model prediction (Big Data) and sensor technology that can reduce environmental pollution and save water resources, leading simultaneously to higher yields with improved quality (foodwaste reduction). This, in general, will improve plant health by reducing pest and disease pressure, thereby reducing the need for pesticide and herbicide use and improving food safety.


Research approach

New fully functional wood fibre-based growing media for professional hydroponic plant production are developed. Raw material from spruce, and admixtures of wood-based substrates designed for plant production in high tunnel and greenhouse are evaluated. Optimized fertilization and watering strategies for the novel substrates based on sensor monitoring are developed. New knowledge on plant growth in selected sustainable wood-fibre based substrate prototypes is gathered and communicated. New promising growing media are tested and evaluated by professional Norwegian growers.


Relevance/Valorisation

In the last hundred years, one third of the peatlands in Norway have been destroyed. The peatlands are threatened by peat extraction, agriculture and urban development. The EU has also officially stated that use of peat in the horticultural industry is a concern and political pressure on reducing peat use continues. Developing peat free media is a crucial issue for a sustainable future for the horticultural industry. Additional knowledge about plant nutrition requirements and sensor based fertigation will improve our understanding of plant physiology and make horticulture more precise and resource efficient. SUBTECH will considerably shift the paradigm and change the way of thinking about growing media.
