Sensitivities of Physical and Chemical Attributes of Soil Quality to Different Tillage Management

Tillage management is a direct factor in affecting soil quality, which key sustainable agriculture. However quality evaluation needs significant manpower, material resources and time. To explore the sensitive indicators of affected by tillage management, eight physical chemical properties under three managements, including plow tillage, subsoiling rotary were determined long-term experiment North China Plain. The results showed that had highest organic carbon total nitrogen 0–20 cm layer lowest bulk density 30–40 layer. Rotary water content 0–40 Meanwhile, compared to 2002, carbon, varied greatly 2012, but there was no difference between 2012 2018. However, other property concentrations tended increase In addition, linear relationship index grain yield. Subsoiling gain yield both can be evaluated through indicator nitrogen, density, phosphorus content, provides scientific basis for selecting reasonable evaluating this agricultural production area or similar areas.
