WP 4: Soil microbiota in soil strata to support crop growth

Accumulation of organic matter in the topsoil layers compared to inversion tillage and/or the use of organic fertilisers as stated in TILMAN-ORG favours microbial biomass, activities and changes community structure and function. We will investigate in FertilCrop how these changes influence important functional traits of the soil microflora related to nutrient turnover and plant health taking sites with differing climatic conditions and forms of reduced tillage management into account. In addition, we will investigate how deeper soil layers are affected with respect to soil organic matter fractions, microbial biomass and activities, decomposition of crop residues and the composition and diversity of microbial species. Simultaneously, we will link results to data obtained in WP3 and WP5.

The objectives of work package 4 are

  • To analyse the stratification of soil organic carbon, microbial biomass and microbial activities.
  • To follow the decomposition of plant residues in selected field trial treatments.
  • To identify abiotic and biotic drivers for the metagenome of soil microbes and how changes in the structure of the soil microbiome affect activity patterns at the transcriptome level.
