Sustainable land management technologies: integrated soil fertility management
Sustainable Land Management contribution to successful land-based climate change adaptation and mitigation: A report of the UNCCD Science-Policy Interface (SPI)
Integrated soil fertility management (ISFM) is a set of soil fertility management practices that aim to optimize nutrient use efficiency and improve crop productivity. WOCAT describes ISFM as a technology that "is based on three principles: maximizing the use of organic sources of fertilizer; minimizing the loss of nutrients; and judiciously using inorganic fertilizer according to needs and economic availability” (WOCAT glossary). ISFM can be use different land use types, such as cropland and grazing land.
According to the report on sustainable land management (SLM) by the UNCCD Science-Policy Interface (SPI), ISFM practices that combine the use of chemical and organic sources of fertilizer, such as livestock manure, can moderately improve soil quality and could provide other benefits such as soil erosion control, water retention, and accumulation of soil organic Carbon (SOC).
The report also indicated that ISFM practices that use plant-derived carbon from external sources, such as from composts and biochar, can be considered a land-based climate change mitigation option due to the ability to reduce Nitrogen losses and greenhouse gas (GHG) emissions, and enable greater accumulation of SOC stocks. Another important benefit of ISFM is the protection and preservation of soil biodiversity, which is important for the efficient functioning of ecosystems and the services they provide, such as nutrient cycling.
