Efficacité de différentes formes d’azote dans la culture du bleuet nain sauvage

The objective of this project was to evaluate the effectiveness of different forms of nitrogen fertilizer in lowbush blueberry cultivation and to determine their impact on soil pH and nitrogen. Nitrogen fertilizers consist mainly of ammonia; they incorporate elements such as sulphur, carbon and calcium, which affect their ammonia concentration and their decomposition in the soil. Only ammonia containing sulphur (ammonium sulphate) helped lower and maintain the soil pH, which is desirable in blueberry cultivation, while also ensuring high nitrogen availability to the crop. The different forms of nitrogen fertilizer had no impact on fruit yields.
