　　Tillage practices play an important role in the sustainable agriculture system.Conservative tillage practice can help to reduce soil erosion,increase soil fertility and improve water quality.Tillage practices could be applied at different times with different intensity depending on the local weather condition and farmer's assessment.Remote sensing approach has been applied to identify tillage intensity at field scales by mapping crop residues left on the soil surface shortly after planting.
