Resumen :
Population growth leads to an increase in the demand for energy, water, and food as cities grow and urbanize. However,
the Earth's limited resources are unable to meet these rising demands.Modern farming practices increase productivity,
but waste resources and consume too much energy. Agricultural activities occupy 50 % of all habitable land.
After a rise of 80 % in 2021, fertilizer prices have increased by nearly 30 % in 2022, representing a significant cost
for farmers. Sustainable and organic farming has the potential to reduce the use of inorganic fertilizers and increase
the utilization of organic residues as a nitrogen (N) source for plant nutrition. Agricultural management typically prioritizes
nutrient cycling and supply for crop growth, whereas the mineralization of added biomass regulates crop nutrient
supply and CO2 emissions. To reduce overconsumption of natural resources and environmental damage, the
current economic model of “take-make-use-dispose” must be replaced by “prevention-reuse-remake-recycle”. The circular
economy model is promising for preserving natural resources and providing sustainable, restorative, and regenerative
farming. Technosols and organic wastes can improve food security, ecosystem services, the availability of
arable land, and human health. This study intends to investigate the nitrogen nutrition provided by organic wastes
to agricultural systems, reviewing the current state of knowledge and demonstrating how common organic wastes
can be utilized to promote sustainable farming management.Ninewaste residues were selected to promote sustainability
in farming based on circular economy and zerowaste criteria. Using standard methods, theirwater content, organic
matter, total organic carbon, Kjeldahl nitrogen, and ammonium levels were determined, along with their potential to
improve soil fertility via N supply and technosol formulation. 10 % to 15 % of organic waste was mineralized and analysed during a six-month cultivation cycle. Through the results, the combination of organic and inorganic fertilization
to increase crop yield is recommended, as is the search for realistic and practical methods of dealing with massive
amounts of organic residues within the context of a circular economy.
