We propose to investigate the tripartite, PGPM-plant-soil microbiome interaction in plant quality and productivity using state-of-the-art ‘omics’ and bioinformatics approaches to investigate facilitation (positive interactions) and competition (negative interactions) by both microbes and PGPM within the plant realized niche following gradients of both soil diversity and nutrient availability. This research proposal integrates approaches to obtain a fundamental understanding of these tripartite interactions in a smart microbiome engineered plant production system for sustainable high-quality crop production. This research will contribute to the development of innovative methods for agricultural and horticultural starting material production using PGPM for sustainable crop production by combining techniques to reduce nutrient input and enhance the efficiency and long-lasting effects of PGPM.

Doel van het project

As manifested in national and international policies, society is increasingly demanding sustainable primary production with lower external inputs and environmental burden.
The results of this project will be applicable nationally and globally in the design of management tools that will allow plant growers to improve and optimize the quality and consequently the value of their crops using PGPM (strategies and tools for efficient soil microbial farming). These integrated management practices will include PGPM and lower nutrient inputs to ensure soil microbial diversity and functionality for high plant quality and sustainable plant production, as well as recommendations to farmers in the flower sector for best management practices for plant propagation and high-quality crop production. The results will allow the private consortium partner to successfully design customized plantlet-PGPM mixtures for farmers demanding sustainable plant growth.

Relatie met missie (Motivatie)

Chrysanthemum (Dendranthema grandiflora) is the employed plant model system in this project because of its importance in the flower sector in the Netherlands, the market leader with chrysanthemum exports totaling €250 million annually. In addition, there is an urgent need to reduce fertilizer application in the flower sector to attain sustainable crop production.
Plant-growth promoting microbes (PGPM) are a viable alternative to traditional fertilizers for enhancing plant productivity and improving soil quality without environmental pollution.
