Nitrogen (N) is a key nutrient for the successful production of crops, and each year growers invest significantly in applying N fertilisers. However, not all the applied N is used by the crop…
The Sustainable Vegetable Systems (SVS) program has made great progress with trials and data forming the foundation for interesting conversations around the support that growers need for improved financial and environmental performance alongside compliance reporting. The highlight from this quarter is that the prototype farmer tool has been developed (see Workstream 3). Workstream 1 – The Plant & Food…
