Precision fertilization

Large variations within a field could indicate that precision fertilization could be a succesful strategy.
Precision fertilization means that fertilization is adapted to the plants' specific nutrient needs at different locations within a field. Precision fertilization requires effective mapping of this need, along with equipment that can efficiently apply variable amounts of fertilizer.
The need for plant fertilization will vary within a field based on variations in soil properties, topography, weather conditions, microclimate, and the impact of previous agronomic practices such as drainage, soil compaction, and crop rotation. Through precision fertilization, we aim to adjust fertilization to these variations in need by applying variable amounts of nutrients. Technologies such as GNSS, sensors mounted on platforms like satellites, drones, or ground-based equipment, along with machine learning and artificial intelligence, are used in research to map site-specific variations in fertilization needs.
Both we at the Center for Precision Agriculture and other research communities have shown that site-specific nitrogen fertilization increases farmers' profitability while also reducing negative environmental effects such as runoff.
Our work in this field began in 2001, and we have specifically focused on the challenge of identifying actual nitrogen needs when the plant is exposed to multiple stress factors simultaneously. We have examined stress factors such as too much or too little water, weed competition, and disease outbreaks. The work has primarily been focused on grains and berries.

PRESIS
I PRESIS, et nytt femårig samarbeidsprosjekt, skal NIBIO være med å videreutvikle teknologiske løsninger for enda bedre presisjonsjordbruk, og samtidig sørge for at løsningene kommer ut i praksis til gårdene.
