The titanium /Ti/ content soluble in percholoric-acid of 0.8-3.1 g/kg and changing concurrently with soil thickness was determined in 60 upper soil samples. The Ti-content of feeds of plant origin moves mainly between 1-40 mg/kg. In the feeds with higher Ti-content was Al, Fe and Si content is also higher. The correlation between Ti- and B-concentration in the plants can be explained by ecological factors /salty, sodic soils/. The Ti-Cr correlation is rather of a biochemical character. The cattle eject nearly the whole quantity of the ingested Ti with their faeces in which 51-265 mg/kg Ti was found /on dry-matter basis/. The literature concerning to several percentage retentions is supposedly incorrect. The Ti-content of soils and plants is practically not influenced by the environmental pollution caused by sewage mud and coal burning. The Ti seems suitable as an indicator in the analysis of cattle faeces from the staindpoint of mineral matter supply.
