Task 2 – Quantifying effects of diversity on total yield and nitrogen replacement value in multispecies mixtures

Task 2 of Multi4More aims to investigate the nutrient replacement value and optimal functional group proportions of grass, legume, and herb in multispecies mixtures across three sites using a simplex design experiment. The study will measure dry-matter yield, nitrogen replacement value, and the nutrient use efficiency of mixtures under varying proportions of grass, legume, and herb, and different levels of nitrogen fertiliser. The consortium includes world-leading experts in statistical analysis, and the study will also conduct a literature review and monitor the influence of environmental factors.
