Topics and key points included:

  • Energy capture is strategic and time-dependent
  • Keep useful resources within the system
  • Loss of biodiversity, habitat destruction, e.g. 99% of hay meadows in Wales have been lost
  • Grazing and meadows
  • Agroecology
  • Agroforestry
  • Climate change, atmosphere, solar energy and radiation balance
  • Photosynthesis
  • Soil formation
  • Soil horizons
  • Soil micro-organisms, fungi and other species
  • Fungal inoculation of soil, trees, straw, e.g. trees inoculated with truffle fungi, shitake mushrooms grown on logs or straw
  • Healthy topsoil is about 50% air by volume, in pores between soil particles – soil compaction results in reduced air within the soil
  • Soil type is determined by mineral particle size – e.g. sandy, clay, loam, silt, with sandy soil having the largest particle size and clay having the smallest particle size
  • Negatively charged clay particles, enable nutrient exchange between the soil and plant roots
  • Peat
  • Carbon sequestration
  • Biochar
  • Transport
  • Community gardens
  • Weeds repair the soil/ecosystem, indicate soil conditions and are fast carbon pathway plants, many are edible
  • Visit to Erleigh Road Community Garden, Reading (St. Luke’s Church)
