Martin Weih
Martin Weih is a professor of plant ecology and eco-physiology of agricultural crops. Main research focus of his lab is on PLANT GENOTYPE AND ENVIRONMENT INTERPLAY IN CROP PRODUCTION. Major research activities focus on the improvement of yield and ecological sustainability (e.g., resource use efficiency) of agricultural crops grown for food, feed and biomass (e.g., wheat for food; Salix and Populus for biomass). We also evaluate how genetic variations with respect to specific traits or functions of plants (e.g., different species or varieties, including genetically modified plants) affect other functions of the same plant and the ecosystem in which it is grown.

Research

Linking plant traits to productivity and ecosystem processes for development of sustainable solutions in agriculture

We investigate how we can make the best use of crops and the environmental conditions under which they are grown, in order to develop sustainable solutions for the production of food, feed and biomass. To achieve this, we investigate the links between individual plant traits (crop species or cultivars), crop yield, the production systems design (e.g. nutrient management, cultivation in monocultures or mixtures), and the processes that are relevant for supporting important ecosystem services (e.g. reduced nutrient losses, pest and disease control, enhanced biodiversity). Study systems mainly include cereals and cereal – legume mixtures for food and feed production; and willows and poplars grown on agricultural land for biomass production. Specifically, we address the above issues by means of various research projects with external funding from Formas, the Swedish Energy Agency, the Swedish farmers’ foundation for agricultural research (SLF), the European Union and Novo Nordisk Foundation.

The ECOLINK-Salix project is part of the global tree diversity network TreeDivNet and comprises currently two experimental field trials (one in Uppsala and one in Rostock, Germany). The overall goal of ECOLINK-Salix is assessing the effects of genotype identity and diversity in willow short rotation coppice on various ecosystem functions and, ultimately, willow growth and yield stability (e.g. resistance to drought and pests), and a summary of our corresponding research is presented on this video from my presentation at the IPC26 conference. ECOLINK-Salix is also a core infrastructure for the project MixForChange - Mixed Forest plantations for climate Change mitigation and adaptation

Focus on genotype – environment interaction, crop improvement and stakeholder interaction is a main characteristic of the NEWp (Nutrient Efficient Wheat partnership) project, which is a collaborative research project linking root characteristics, nutrient use efficiency and the sustainable production of spring wheat. Root characteristics are the main focus also in the HeRo - Healthy Roots project (Development of tools for the selection of robust cultivars in Swedish plant breeding, with focus on the root system). NEWp and HeRo involve the collaboration with a wheat breeder (Lantmännen) and an advanced plant phenotyping facility in Germany, which gives us access to the technology of high-speed phenotyping of a large number of relevant plant traits that we try to link to ecological processes in subsequent field-testing.

The mission of N2CROP is to establish an international hub for cutting-edge grain legume research and innovation and, ultimately, achieve sustainable agri-food systems powered by biologically fixed nitrogen to deliver high-quality plant food protein. We are here responsible for planning, implementing and evaluating a series of field trials where various cultivars and mutagenic lines of field bean with altered properties are intercropped with wheat and oats.

As a partner within the BalticWheat network, we explore new opportunities for promoting sustainable wheat production in the Baltic Sea region.

While NEWp mainly explores the route genotype – plant traits (phenotype) – resource economy, the project Improving yield and quality in Swedish wheat production – influence of nitrogen fertilization strategy and cultivar (project leader Karin Hamnér, Dept. of Soil and Environment, SLU) links wheat cultivar characteristics to nutrient management in order to improve the efficiency and sustainability in wheat production.

DIVERSify (Designing InnoVative plant teams for Ecosystem Resilience and agricultural Sustainability) was a European consortium of scientists, farmers, advisors, breeders and SMEs to co-construct a new ecological approach and tools to investigate the mechanisms underpinning the benefits associated with cropping plant teams, and the plant traits and agronomic practices promoting these benefits. The plant teams which we investigated in Swedish field trials included wheat – faba bean and barley – pea (all grown as sole crops and mixtures).
