Dynamics of Temperature Variation in Soil under Fallow Tillage at Different Depths

One of the important processes taking place during soil surface tillage is variation temperature at different depths. The paper presents results research into dynamics in terms such parameters as its thermal diffusivity and oscillation frequency. It has been established that amplitude decreases when depth increases, following logarithmic law. In this variation, difference between 0–5 cm layer adjacent 5–10 greatest value. This circumstance a favorable factor for fallow technology, where regularly cultivated to no more than 5 cm, case moisture deficit. A decrease frequency oscillations can result reduced level heating layers. qualitative changes, reduction being lowered same time maximum these shifted towards delay.
