Fertilise the exact areas of your field that need it
Scarcely any plot of land is intrinsically homogeneous and offers the same yield potential throughout. Practical data shows that: When fertiliser is spread evenly in accordance with the German Fertiliser Application Ordinance (DüV), it leads to an oversupply of your fields in 33% of cases. In 42% of cases, it actually leads to an undersupply of the fertilised field sections. If you fertilise each section precisely according to its yield potential, it enables you to realise its full yield potential, all while optimising your use of supplies and farming in a more environmentally friendly, sustainable way.
In areas with lower yield potential, you get money back in your pocket. This means that with the same amount of N fertiliser, you harvest on average 10% more than you would if spreading the fertiliser evenly. Especially in areas where farmers are legally required to reduce nutrient supply, you can continue to ensure your crops have a sufficient supply of nutrients by utilising site-specific fertilisation.
- No nutrient losses in low yield zones
- Adequate supply in high yield zones
- Long-term protection of both yield and quality
- Healthy crops that are full of life as a result of an optimum nutrient supply
- Utilise materials efficiently
- Damage limitation for the 20% allowance for fields in red areas/nitrate vulnerable zones
- Integration of various sensor processes (satellite data, nitrogen sensor)
- Site-specific basal dressing based on soil tests
The N-Manager makes it even quicker and easier to plan your N fertilisation site-specifically based on a mapping approach. How it works. Based on the SS yield potential maps, fertiliser requirement calculation values, amount of partial applications and the selected fertiliser, an algorithm automatically generates prescription maps for nitrogen fertilisation. They can then be visualised in the Prescription Map Center and tweaked as necessary.
Where N fertilisation is used in partial applications for crop management (cereals), N-Manager Pro is the ideal tool for quickly and easily creating fertiliser prescription maps. The map for the first partial application at the beginning of the growing season is created based on the yield potential map (N-Manager). After this point, the biomass growth is represented in a validated simulation model and compared against current satellite observations. This enables annual effects that deviate from the yield potential map to be identified and your N fertilisation measures to be readjusted more precisely to your plants/crops. This means that each time you are about to carry out N fertilisation, you can feed up-to-date nitrogen requirement maps into N-Manager. A fertiliser prescription map is then generated based on these maps.
Scarcely any plot of land is intrinsically homogeneous and offers the same yield potential throughout. Divergent soil characteristics require a differentiated farming approach. TalkingFields satellite maps also show that there are differences within the field. As such, a homogeneous cultivation approach over the entire field is uneconomical. Seed, fertiliser and plant protection products have a significantly greater effect if their dosage is regulated (adapted to the soil) throughout the field.
Fertilising without NEXT N-Manager
Generally, a pre-determined, consistent amount of nitrogen is applied to a plot of land. The amount is calculated based on the average yield potential. Field sections with a lower yield potential are over-fertilised. The plants are unable to take up the excess nitrogen and it is washed out of the soil. This harms the environment and wastes resources. Field sections with a higher than average yield potential, on the other hand, are often under-fertilised. In this case, the maximum yield potential cannot be realised.
Fertilising with NEXT N-Manager
Regardless whether a field section has a high or low yield potential, it is fertilised precisely according to its potential. This enables you to realise your field's full yield potential while optimising your resource usage and farming in a more environmentally friendly, sustainable way. In areas with lower yield potential, you also save on costs. This means that with the same amount of N fertiliser, you harvest on average 10%* more than you would if spreading the fertiliser evenly.
