Research data were obtained on sandy loam Eutric Albeluvisols at the Kaltinenai Research Station of the Lithuanian Inst. of Agriculture on the undulating hilly topography of Western Lithuania. Results from 18-years of field investigations show significant increases in soil organic matter (SOM) content under grass-grain crop rotations compared with field and grain-grass crop rotations. SOM content was analyzed using the Tyurin titrimetric method, which is not widely used in Western Countries. Therefore, SOM data are also presented after split analysis using dry combustion, Walkley-Black (USDA) and loss-on-ignition (UK) methods. Transfer functions permit transfer between databases. International comparison of SOM databases will assist in many tasks, including evaluating the importance of SOM/SOC in international collaborative terrestrial ecosystem studies and the development of effective soil conservation policies.
