Making up 78 percent of the air, nitrogen is an essential element to life on Earth. It’s a component of all proteins and can be found in all living systems. Nitrogen compounds are also present in organic materials, foods, fertilizers, explosives and even poisons.
As in the air, nitrogen occurs naturally in organic form in the soil, constantly cycling between the soil and the air. This ‘nitrogen cycle’ is necessary to convert unavailable atmospheric nitrogen to plants available ammonia and nitrates ions. Microbes and bacteria in the soil (nitrogen fixators) ‘fix’ nitrogen directly from the atmosphere and
convert it into ammonium and nitrates, e.g. compounds available to plants. Plants and algae use those nitrates to build up the bases needed to construct DNA, RNA and all amino acids necessary for proper functioning of the animal metabolism which obtain nitrogen by consuming plants.
Seeking for higher yields, farmers add various chemical and biological fertilizers to the soil. Actually, to achieve yields expected in today’s modern farming, many crops require additional N fertilization, thus making it the most limiting nutrient in crop production.
Since scientists managed to transform nitrogen gas into a digestible form of ammonia, the era of widespread fertilizer use in croplands has begun. Nitrogen has many positive effects on farm and industrial production systems, human nutrition and food security. Without it, plants are weaker and smaller.
Although nitrogen is crucial for plant growth, farmers need to be very careful when applying nitrogen into the soil. It can be easy lost to the environment due volatilization, denitrification, leaching due to excessive rainfall, evaporation and lost by runoff. Losses influence the ecosystem, soil characteristics, cropping pattern, fertilizer techniques and overall farm production management.
Low nitrogen recovery is responsible for higher crop production costs and environmental pollution as well, so farmers are working on improvements of nitrogen use efficiency. To do that, they need to follow management and conservation practices in their farm production such as;
There are many ways how a farmer can improve nitrogen efficiency use. Knowing soil characteristics and crop demands are essential for proper nitrogen management in the soil.
Besides following management practices of nitrogen use efficiency, farmers also want to know cost effectiveness of applied fertilizers. Agrivi farm management software helps them track spent quantities of all fertilizers per fields and crop productions, with related cost. It gives them also an insight on used quantities of each nutrient per fertilizers, crop productions and fields. With only one click, they can see which field is higher or lower in fertilizers and related nutrients.
