The measured impact of innovative agricultural managment practices (AMPs) was assessed using data collected during the 2018 field campaign.

With the caveat that individual results (pairs of AMP/control) at a specific agro-climatic condition, cannot be used to infer results elsewhere, Figure 29 depicts the impact of different AMPs on soil threats measured at the iSQAPER case study sites.

White cells indicated that data was not sufficient to perform the calculation. Red cells indicate poor condition, yellow indicates moderate condition and green good condition.
Where the length of the fields was not provided for the calculation of erosion, a length of 100 m was assumed.
Rainfall erosivity factor and biodiversity potential were read on low resolution maps and may not represent local conditions.
Details of the AMP groups are given in Table 1. The numbers of each case study site identify the respective pair of AMP/Control.
