Nitrogen fixation
The process by which atmospheric nitrogen is converted into ammonia or related nitrogenous compounds that plants can use.
Также говорят: biological nitrogen fixation, N-fixation, nitrogen assimilation
Nitrogen fixation is a vital agricultural process primarily facilitated by symbiotic bacteria within the root nodules of leguminous crops. This biological mechanism serves as a sustainable alternative to conventional synthetic fertilizers.
Farmers apply this practice by inoculating seeds with specific bacterial strains to ensure effective colonization. The success of nitrogen fixation relies heavily on soil pH levels, adequate moisture, and the presence of essential micronutrients like molybdenum or boron.
Common mistakes include the improper handling of biological inoculants, such as exposure to direct sunlight or high temperatures, and failure to adjust mineral fertilizer programs when the fixation process is highly active.
