“…Crop straw, which could increase organic matter content [ 38 ] and aggregate stability [ 39 , 40 ], should be incorporated into the subsoil during Aw and B layer mixing. The results of the present study indicate that the positive effects of mixing the Aw and B layer soils on improved crop yield in Albic soil using different subsoil mixing ploughs [ 21 , 24 , 25 ] (i.e., in the TSMP, FMSP, and TSIMP treatments) could be sustained for at least two years. Although using a subsoiler method (i.e., the CS treatment) can also facilitate Albic soil improvement [ 16 , 19 ], the positive effects last a relatively short period and the mixing has to be undertaken annually.…”

“…The TSMP can mix the Aw and B layers of Albic soil at a 1:1 ratio while leaving the Ap layer undisturbed [ 20 – 23 ]. In contrast to the typical subsoiling technique, subsoil hardness did not return to the initial level; therefore, Aw soil permeability increased 1.7–7.3-fold, and soybean yield increased by 11.4% [ 24 ]. A Four-stage subsoil mixing plough (FSMP), which applies similar principles to those of the TSMP for improving soil, was developed in 2002 [ 25 , 26 ]; however, it could also apply wheat straw, maize straw, and fertilizer into the 20–40-cm soil layer [ 25 ].…”

“…In addition, a three-stage subsoil interval mixing plough (TSIMP) was developed in 2010. It represented an increase in working width from 46 cm (TSMP) to 92 cm, and it improved soil improvement efficiency, increasing soybean yield by 4.5% when compared with CS [ 24 ]. Although such developments have provided mechanical and theoretical frameworks for the improvement of Albic soil, there is a lack of comparative studies based on the physicochemical properties of Albic soils managed using different Subsoil Mixing ploughs.…”

Crop productivity in Albic soil is poor, owing to poor soil physicochemical properties. Mixing of Aw layers, representing Albic soil, with B layers, could improve the physicochemical properties of Albic soil, which is characterized by poor humus on the topsoil and high penetration resistance. The objective of the present study conducted in 2015-2016 in an Albic soil region in Heilongjiang province, China, was to explore the effects of different soil mixing strategies on the physicochemical properties of Albic soil and crop yield. There were four soil mixing treatments: conventional subsoiler (CS), three-stage subsoil mixing plough (TSMP), four-stage subsoil mixing plough (FSMP), and three-stage subsoil interval mixing plough (TSIMP). Our results demonstrated that the Aw layer bulk density of Albic soil under TSMP, FSMP, and TSIMP decreased significantly compared to that under CS. In addition, the total porosity of the soil under these treatments increased significantly in 2 years. Compared to the water holding capacity under the CS treatment, other treatments increased significantly in the Aw layer. Furthermore, soil penetration resistance of the Aw layer decreased following Aw and B layer mixing. All three soil mixing treatments also increased soil aggregate stability and cation exchange capacity but reduced soil organic carbon content in the Aw layer. Soil mixing increased soybean and maize seed yield. Overall, Aw and B layer mixing improved Albic soil structure and physiochemical properties and increased crop yield; thus, this mixing is a feasible approach for Albic soil improvement, with optimal improvements observed under the FMSP strategy, which also added organic substances to the Aw layer.

A three-stage subsoil interval mixing four-gang plough (TSIMF) was created to ameliorate the condition of the planosol soil. To obtain wider working width (2 m), the previously designed three-stage subsoil interval mixing plow (TSIM) (working width = 1 m) was doubled and unified. The soil penetration resistance was measured before and after the tillage operation of the TSIMF to contrast the tilling effect. The predicted draughts and the predicted draught moments were also calculated and compared for the previous and present prototypes: Three-stage Subsoil Mixing Plow (TSM), Three-stage Subsoil Interval Mixing Plow (TSIM), and TSIMF. The predicted total draught and the minimal predicted draught moment of the TSIMF were discussed to find out the proper working traction which could keep the tractor running straight and making it proceed ahead with balance. The results showed that the soil penetration resistance was reduced obviously after the tillage of the TSIMF. The predicted total draught of the TSIMF will be about 90 kN including the running resistance of the tractor. The predicted draught moment of the TSIMF will be the smallest of three multi-stage mixing plows at -10 kNm when the tractor width is 2 m.
