Initial assessment of projected trends of SOC in English arable soils - SP0533

Description
Development of a sustainable farming and food production sectors is a key Government objective.

These include Topsoil organic carbon in soils under arable and rotational grass which is set in the context of the sustainable use of natural resources to support life, biodiversity and economic activity.


The overall objective of this proposed work is to re-model current national soil SOC stock to ascertain the level of variability associated with broadly defined SOC categories within the two main textural groups of soil (coarse and fine topsoil materials), and to ascertain whether the perceived current trends in SOC concentrations are genuine and sustained over recent years.It is also to determine whether these trends are indicative of a longer term trends and whether they are likely to continue over the next decade for the current mix of management practices.
Objective
To re-model current national soil SOC stock to ascertain the level of variability associated with broadly defined SOC categories within the two main textural groups of soil (coarse and fine topsoil materials)and that associated with the numbers of sites changing from one category to another.

To ascertain whether the perceived current trends in SOC concentrations are genuine and sustained over recents years and whether they are indicative of a longer term trend or counter to this underlying trend.

To identify and quantify the impact of arable land management changes made over recent decades on SOC concentrations and link these changes with recent SOC trends.

To predict the likely trend in SOC concentrations over the next decade for the current mix of management practices given the scenarios of no change the degree of change expected given policy and the degree of change possible for modest changes in policy necessary to address current and underlying trends identified.
