Authorised organic amendments
Compost and permitted amendments that feed the soil.
When green manure is not enough, authorised organic amendments round out organic nutrition: compost, composted manures, meals and other amendments from the permitted-input list.
They supply slow-release nutrients and organic matter that feeds the soil. The essential thing is to use only authorised inputs, match the rate to analyses and log every application for the traceability certification requires.
Effort
Low to medium — periodic application.
Cost
Variable — low with own compost, medium if bought.
Time to result
1–3 seasons depending on rate and soil.
What it works against

How it works
The organic matter in amendments mineralises gradually through soil biology, releasing nutrients at the pace of the vine’s needs.
How to apply
- 1Analyse soil/leaf to size the need.
- 2Select only organically-authorised amendments.
- 3Apply the matched rate, preferring modest, regular applications.
- 4Log product, rate and plot for certification.
What to measure
Frequently asked
Can any manure be used in organic?
No. There are restrictions on origin (e.g. from intensive livestock) and you must confirm the authorised-input list and the certifier’s rules.
Better one big dose or regular applications?
Modest, regular applications give a better soil response and lower risk of excess that raises vigour and disease susceptibility.
