The optimal quantity of organic manure required to sustain soil fertility while mitigating the accumulation of heavy metals
Research gap analysis derived from 3 agriculture papers in our local library.
The gap
Therefore, the optimal quantity of organic manure required to sustain soil fertility while mitigating the accumulation of heavy metals and other nutrients resulting from continuous application remains unclear.
Evidence profile
Sourced from the abstract and future-work section of the source papers, classified as general, drawn from work published between 2025 and 2026, spanning 3 journals. Those papers have been cited 10 times in total.

Manures are a renewable source of P that could partially offset the use of mineral fertilisers, but their agronomic value and behaviour in soil remain less clear due to limited information on their chemical composition.

Further studies are needed to explore the potential of organic manure-based substrates in geotextile pockets for other crops and environments. The development of sustainable and productive vertical farming systems using organic manure-based substrates is an area for future research.
