Control
Control - is required to give validity to the
experiment. It represents what would happen if we did nothing and is used
to compare against the other plots. It is as close to nature as possible
with minimal human intervention i.e. no digging & no compost. |
No-Dig
No Dig - Instead of digging the soil, compost
and other mulches are used to cover it allowing the biology to incorporate
it into the soil structure.
|
Single-Dig
Single dig - The soil is dug to the depth of
one spade deep and the compost is incorporated at the same time, mixing it
in to the soil structure.
|
Double-Dig
Double dig - The soil is dug to the depth of
two spades. The first spades depth is removed. Then compost is
incorporated into the second spades depth, mixing it into the sub soil
structure.
