The Effects of Tillage on the Temperature and Water in an Unsaturated Soil Zone

Abstract

The field experiments were conducted by using two columns in order to estimate the effects of tillage on the temperature and water in an unsaturated soil zone. The effects were shown by being compared with values obtained in the no-till column. The results were as follows: an increase in soil temperature in tilled zone; an increase of pressure head below the tilled zone; a reduction of cumulative evaporation by tillage; and increased air temperature near the soil surface.
