Título em português: Alterações da temperatura em solo coberto de palha de aveia-preta.  aThe objective of this work was to evaluate the effect of different amounts of black oat (Avena strigosa) straw covering soil surface on soil temperature at different depths. The treatments consisted of 0, 3, 6, and 9 Mg ha-1 straw. Soil temperature was measured hourly by a thermocouple inserted at different depths (0, 5, 15, 30, and 50 cm) and was used to adjust an equation correlating the temperature of covered soil with that of bare soil. With the correlations, it was possible to observe a point value of temperature (inversion temperature of straw effect), below which the presence of straw acts positively on the maintenance of soil temperature and above which the presence of straw acts negatively on soil heating.  aNo-tillage  aSoil temperature regimes  aAvena Strigosa  aEfeito da palha  aInversion temperature  aMulch effect  aPlant residue  aRegime térmico do solo  aResíduo vegetal  aTemperatura de inversão1 aREINERT, D.
