Can investigate the relationships between soil properties
Research gap analysis derived from 4 agriculture papers in our local library.
The gap
Further studies can investigate the relationships between soil properties and crop yields. The use of other spatial interpolation techniques, such as kriging, can be explored.
Evidence profile
Sourced from the stated research gap and future-work section and abstract and conclusions of the source papers, classified as general, drawn from work published between 2009 and 2026, spanning 4 journals. Those papers have been cited 19 times in total.

Reanalysis products have substantial biases in soil temperature estimates, particularly in winter. The availability of in-situ soil temperature records is limited, particularly over permafrost regions.

Although many macroscale soil maps suggest strong relationships between soil properties and climate, few studies have explicitly demonstrated those relationships using unclassified point observations.

These results suggest that although soil properties remain indispensable, crop rotation and climate variables provide complementary information—particularly in contexts where soil data are limited or costly to obtain.
