Soil Quality

Applies to: CR Collection

Description:

This indicator refers to the prevention of negative impacts of residue removal on soil quality. The indicator considers whether the project involves residue removal from the fields (e.g. in the case of straw) or residues from industrial processing of the crop are used (e.g. husks), and suitability of land for crop production. Land suitability classification is defined as “an appraisal and grouping, or the process of appraisal and grouping, of specific types of land in terms of their absolute or relative suitability for a specified kind of a specific kind of use, function or service, or a specific combination of these”.

Questions:

Does the project involve crop residue removal from the fields?

What is the soil quality in the project area?

Rating:

No residue removal from the fields

Land used is highly suitable for crop production

Land used is moderately suitable for crop production

Land used is marginally suitable/not suitable for crop production on less than 10% of land

Land used is marginally suitable/not suitable for crop production on more than 10% of land
