Agriculture from a nitrogen perspective
Nitrogen (N) is an essential macronutrient for both plants and microorganisms. It is a component of DNA, RNA, chlorophyll, and countless enzymes.
🪏 The forms of nitrogen in the soil that are bioavailable to organisms are mainly:
dissolved inorganic nitrogen compounds,
organic nitrogen molecules with various structures (monomeric or polymeric).
🌱 In these forms, nitrogen can be absorbed directly by plant roots or utilized by numerous soil microorganisms.
♻️ At the same time, the content of this element is a dynamic property of the soil, as the interaction between microorganisms, plants, and minerals regulates its availability.
đź“š A 2021 study by Daly et al. reveals an incredible network of this cooperation, which led to the following observation:
Lower fertilizer use motivates plants to develop stronger root systems and establish mycorrhizal symbioses.
Soils with minimal fertilization release more bioavailable nitrogen from mineral-associated organic matter (MAOM).
Microbial growth occurs alongside a decrease in ammonia levels and nitrogen losses.
đźšś Minimal fertilization strategies can increase long-term soil productivity while significantly reducing agricultural production costs.
🌾 By creating conditions conducive to the growth of microorganisms, it is possible to develop efficient crop production systems that minimize environmental impact while maintaining crop yields.
