CHANGES IN SOIL MICROCLIMATES BY USING DIFFERENT MULCHES AND REMOVING TIME OF PE FILM IN GARLIC (ALLIUM SATIVUM) FIELD
This experiment was conducted to examine the effect of different mulching materials and removing dates of transparent polyethylene film (PE) mulch on soil temperature, soil moisture and air temperature above the soils surface in a garlic field during the period of December, 2008 to March, 2009. The transparent PE mulch without holes retained the highest soil temperature (average 15°C) compared to conventional PE mulch (average 9°C). During the experimental period, the average soil temperature increased about 8°C due to the effect of mulching, compared to bare soil. The air temperature was the highest for the treatment of the modified PE on March 18 (average 13°C) and conventional PE mulching treatment captured the lowest air temperature (average 8°C). PEN (PE+PE net) treatment preserved a high percentage of soil moisture (average 35%) but conventional PE mulching preserved 28%. Soil and air cumulative temperature were highest for the conventional PE mulching treatment followed by PEN treatment during December to February.
