On wheat-maize rotations and nutrient flows in Huantai County, Shandong Province, 14th-16th October 2013
A few key learning outcomes for me were:
•The nitrate levels in the groundwater seemed to be approximately 3x the UK standard
•The water flows in this region are almost all to groundwater, so there is a sense of ‘out of sight, out of mind’.
•There was little real regard or concern for water quality
•According to the Agricultural Bureau, the water quality monitoring is the ‘job for the provisional government’ and that the information is ‘classified’. The bureau did not seem to be aware of any county level programme for protecting water resources.
•Generally there seems to be a nitrogen centric view here, phosphorus was little mentioned although it is used with N and K (in a bagged fertilizer NPK 15-15-15)
