Abstract

Controlled traffic and minimum tillage are expected over time to alleviate degraded soil structure, particularly in rice –based cropping soils that experience annual soil puddling and intensive tillage. However, minimum tillage over time may weaken the plough pan and in turn alter water balance in the rice-based systems. This implication of a change of water balance may be detrimental for rice but beneficial for following crops and for groundwater recharge. The aim of the current study is to determine how soil structure changes over time under continuous minimum tillage system and how changes in soil structure, particularly in the plough pan, affects water balance in rice-based cropping system. This paper reports the magnitude of water balance components in different tillage practices for the Boro rice period of the crop sequence.
