Tailored fertilisation - fruit and vegetables
Level: Spearhead
The use of phosphorus and nitrogen in agriculture is one of the main causes of eutrophication in rivers, lakes, and seas. Requiring that the amount of fertiliser is tailored to the needs of the cultivation and conditions present can contribute to reducing nutrient leaching and to a lower climate impact.

Criterion text
In the cultivation of fruit or vegetables, fertiliser shall be applied in a way that reduces the risk of nutrient leaching. The amount of fertiliser shall be tailored to the needs of the cultivation and the conditions present. This means that:
- There shall be documentation in the form of a cultivation plan, fertilization plan, or similar. This includes the product's nutrient requirements along with planned dosage of phosphorus and nitrogen in the form of mineral fertiliser, manure and/or other organic fertiliser.
- All applications of fertiliser, including watering with fertiliser and/or foliar fertilisation, to the soil or plants, is recorded.
Verification
Upon request, the supplier shall be ready to present, for example:
- Valid licence/certificate for a label/certification that covers the requirement, for example Svenskt Sigill/IP Sigill Frukt och grönt [Swedish Seal/IP Seal Fruit & Vegetables] or equivalent.
Proposed follow-up
This requirement can be followed up, for example, by carrying out spot checks on delivered food products. This can be done, for example, by checking the following:
- Valid licence/certificate for a label/certification that covers the requirement, for example Svenskt Sigill/IP Sigill Frukt och Grönt [Swedish Seal/IP Seal Fruit & Vegetables].
Make use of specialist expertise in your organisation when following up the summitted evidence of compliance. This could, for example, be an environmental or sustainability strategist with extensive expertise within questions related to sustainability.
Information about the criterion
The criterium is relevant for conventionally grown fruit and vegetables. The criterium may be limited by market availability and may vary for different products and be subject to seasonal variation. Conduct a market analysis to ensure availability.
Market analysis (in Swedish)
Fresh fruit and vegetables often lack a unique identification in the form of GTIN and the corresponding article information in the digital system. Therefore, follow-up can require significant resources, for both the purchaser and the supplier.

Environmental goals
Motive
The use of phosphorus and nitrogen in agriculture is one of the main causes of eutrophication in rivers, lakes, and seas. Leaching of phosphorus and nitrogen can cause algal blooms, loss of biodiversity and a less productive ecosystem. Leaching of nitrogen can also lead to the formation of the greenhouse gas nitrogen dioxide, that has a negative climate impact. Phosphorus and nitrogen are one of the areas that are close to or have reached the planatary boundaries1.
In order to transition to a circular economy, it is important that agriculture reduces its dependency on mineral nitrogen, that is produced using fossil-based energy, and virgin phosphorus, that is a finite resource. By tailoring fertilisation, agriculture can conserve resources and reduce the risk for nutrient leaching and causing eutrophication.
It is becoming more common for agriculturists to work with fertilisation plans and to document fertiliser dosages. This is also a way of improving the profitability of the cultivation, as only the amount of fertiliser that is absolutely necessary is used. In Sweden, Focus on Nutrients provides advice to agriculturists who want help within this area, and there are similar initiatives in other countries.
