For soil to remain fatal and healthy microbes need to be present. But that can be a problem. What we are doing basically, either
Council and HortNZ are asking growers on the Poverty Bay and Uawa Flats to complete a survey about the water quality in our rivers. The information from this survey will be used to model estimated nutrient losses from the various land use and soil .
