Soil samples were oven-dried at 105 ◦C to a constant weight to calculate the gravimetric water content. In 2014, we only sampled at the V6 stage, but in 2015, we increased the sampling frequency to include V4. However, at the V6 stage in 2015 (10 Jun for PM, and 3 Jul for CK...
This allows us to calculate their age in each year from 1998 to 2015. We classify their ages into four cohorts: 16–25; 26–35; 36–45; and, over 45. Occupation: we collected detailed information about occupation, including position and industry. For example, were they a worker in a ...
