5.
Do you believe your farm has sub soil constraints leading to yield limitations? (Sub-soil is defined as the underlying layers of soil beneath the topsoil that may contain less organic matter and more characteristics of the soils parent material (i.e. less aged). This is typically below 150-200 mm from the soils surface but can vary in depth depending on soil formation and geological history.)
Yes
No
6.
If yes, please circle constraint and add approximate number of hectares the farm is limited by the associated constraint.
