Bee populations are declining

  • Fields/orchards and monocultures have led to crops needing managed pollination
  • Pollination management involves agricultural practices that ensure the pollination of a crop so that the yield and quality of the crop is improved
  • Often involves commercial beekeepers becoming pollination contractors and transporting the bees to areas where they are needed

DEFINITION

Monocultureis the agricultural practice of producing or growing a single crop or plant species over a wide area and for a large number of consecutive years.

It is widely used in modern industrial agriculture and its implementation has allowed for large harvests from minimal labour.

Beetles, slugs and worms feed on organic material, breaking it down

  • They break down plant litter (dead roots, leaves and grasses) = detritus
  • A complex stable organic material called humus is formed
  • Which improves the texture of soil and adds nutrients to it

DEFINITION

Vermicast, also called worm castings, worm humus or worm manure, is the end-product of the breakdown oforganic matter by an earthworm
