Question 15

Table 1: Soil organic carbon (SOC) stock ( $ha−1\text{t~ha}^{-1}$ ) in an agroforestry plot compared to a conventional arable control plot (2008–2023)

Plot type	2008	2013	2018	2023
Agroforestry plot	42.3	45.8	51.2	58.7
Conventional arable control plot	41.5	39.1	37.4	35.2

Using Table 1, calculate how many tonnes per hectare ( $ha−1\text{t~ha}^{-1}$ ) higher the soil organic carbon (SOC) stock was in the agroforestry plot than the conventional arable control plot in 2018.
