Innovative approach uses nutrients and microorganisms to improve soil fertility, suggesting sustainability benefits.
Climate change has catalysed an increase in global food demand and led to food insecurity. Population growth and adverse impacts on agricultural lands has strengthened pressure on the production of food. The root of this issue is soil degradation. Soil degradation arises from agricultural, industrial and commercial pollution, the reduction of cultivation land due to urbanisation, overgrazing and unsustainable agricultural practices as well as global warming. To mitigate soil degradation and increase food production, numerous strategies have been implemented such as the use of animal manure, chemical fertilisers and organic fertilisers. However, these practices have been proven to be relatively inefficient and ineffective on a large scale. They are also unsustainable for the environment. Recent studies and papers showcase that one of the most efficacious methods for rejuvenating infertile soil and converting it into fertile soil is the implementation of precise microbial and nutrient interventions. The systematic release of essential nutrients and microorganisms will not only transform the soil into a fertile state, fostering a stable ecosystem for crop production, but also serves to prevent issues such as nutrient leaching, runoff, volatilization, denitrification. This approach holds great promise for significantly increasing crop production to meet the burgeoning crop global demands.
