Research gap analysis derived from 3 agriculture papers in our local library.
The gap
The structure of soil pores plays a crucial role in determining the distribution and retention of particulate organic matter (POM) within soil aggregates, yet the specific effects of different straw return practices on POM stabilization through soil pore structure remain poorly understood.
Evidence profile
Sourced from the limitations section and stated research gap and abstract of the source papers, classified as general, drawn from work published between 2024 and 2026, spanning 3 journals. Those papers have been cited 26 times in total.
