The National Environmental Standards for Freshwater (NES-F) introduced new rules for synthetic nitrogen fertiliser use. There are two main parts to the regulation that farmers need to consider: the nitrogen cap and nitrogen reporting requirements.
Since 1 July 2021, all farms in the Horizons Region over 20 hectares with any grazed land must comply with the nitrogen cap regulation which states that no more than 190 kilograms of synthetic nitrogen fertiliser per hectare may be applied per year to:
It is a requirement for all dairy farmers to report their annual synthetic nitrogen fertiliser usage, even if they apply less than the 190 kg/ha/year cap. This includes those that apply 0 kg/ha/year. The annual reporting period is from July to June. For example, the first reporting round took in 1 July 2021 to 30 June 2022. Dairy farmers have until 31 July each year to submit their reporting. The information regional councils require include:
Please note that this reporting applies to all contiguous dairy land – this is the milking platform and any other land directly connected to it. For further explanation on this definition please see here. Reporting tools Regional and unitary councils have worked with Ravensdown and Ballance on a straightforward and consistent method for collecting the required data. We’ve come up with three nitrogen use reporting tools that you can choose from to record your synthetic nitrogen use on grazed land in the twelve-month period from 1 July to 30 June in the following year. The three tools of choice are:
