# mix\_eff

Mixing efficiency of the tillage operation

The mixing efficiency specifies the fraction of materials (residue, nutrients, and pesticides) on the soil surface that are mixed uniformly throughout the soil depth specified by [mix\_dp](/io-docs/~/changes/GiVD5ID0WVyRIAumaMy2/introduction/databases/tillage.til/mix_dp.md). The remaining fraction of residue and nutrients is left in the original location (soil surface or layer).
