Soil quality indicators for sustainable agriculture and the aquatic environment in Northern Ireland


Nutrient Management


Protection Of Soil Quality

Project Objectives

An effective soil monitoring programme is essential to provide the information needed to understand the extent, diversity and quality of our current soil resource and how it is changing. The programme outlined in this proposal should allow us to identify trends, make informed decisions about future soil management and provide much of the information needed to develop soil quality indicators relevant to Northern Ireland.
