“…The regression results show that southward location, low altitude, low slope, annual accumulated temperature ≥10℃ and higher population are the major factors that influence the spatial distribution of cropland. Soil type also has a certain influence on cropland, which agrees with previous studies (Chen et al, 2013;Yao et al, 2015;Zhang et al, 2011). Finally, wetland (0.90) and grassland (0.82) have relatively low ROC values.…”

Spatially explicit modeling techniques recently emerged as an alternative to monitor land use changes. This study adopted the well-known CLUE-S (Conversion of Land Use and its Effects at Small regional extent) model to analyze the spatio-temporal land use changes in a hot-spot in Northeast China (NEC). In total, 13 driving factors were selected to statistically analyze the spatial relationships between biophysical and socioeconomic factors and individual land use types. These relationships were then used to simulate land use dynamic changes during 1980¨C2010 at a 1 km spatial resolution, and to capture the overall land use change patterns. The obtained results indicate that increases in cropland area in NEC were mainly distributed in the Sanjiang Plain and the Songnen Plain during 1980¨C2000, with a small reduction between 2000 and 2010. An opposite pattern was identified for changes in forest areas. Forest decreases were mainly distributed in the Khingan Mountains and the Changbai Mountains between 1980 and 2000, with a slight increase during 2000¨C2010. The urban areas have expanded to occupy surrounding croplands and grasslands, particularly after the year 2000. More attention is needed on the newly gained croplands, which have largely replaced wetlands in the Sanjiang Plain over the last decade. Land use change patterns identified here should be considered in future policy making so as to strengthen local eco-environmental security

“…In our 11-year tillage and rotation trail, tillage showed great impacts on BD and PR (P<0.01), however, rotation had no remarkable impacts on BD and PR. The same results were also observed by Chen et al (2012Chen et al ( , 2013 who found NT increased soil BD in 0-20 cm depth and soil PR of surface layer. Therefore, we speculate that soil BD and PR might thereby affect lodging under different tillage.…”

Corn lodging can damage corn growth and reduce corn yield, and the degrees of corn yield loss could vary with corn species, soil conditions, agronomic practices as well as the degrees of external forces from strong wind or heavy rain. In August, 2012, Jilin province, China suffered from Typhoon Bolaven and large areas of corn lodged. However, in some no-tillage (NT) fields of this area corn lodging is much less serious than in other fields. We assumed that NT led to less serious lodging. We conducted this study on a long-term tillage trial which was seriously hit by Typhoon Bolaven. The experiment consists of NT, moldboard plow (MP), ridge tillage (RT) with continuous corn (CC), corn-soybean (CS), and corn-corn-soybean (CCS) rotations. The most serious lodging occurred in MP-CC treatment, followed by NT-CCS, NT-CC, NT-CS, MP-CS, and RT-CS. The lower incidence of lodging occurred in CS rotation. Soil bulk density and penetration resistance were not major factors affecting corn lodging except for MP-CC plot where root lodging occurred. The ratio of 2012 to average of 2007-2011 corn yield took the order of MP-CC < NT-CCS < MP-CS ≈ NT-CS < NT-CC < RT-CS ≈ MP-CCS. It suggested that RT has more advantages than NT and MP in preventing yield loss from strong wind and heavy rain. Moreover, adoption of RT combined with CS rotation could be taken into consideration preferentially for lower lodging and higher yield in Black soils in Northeast China.

Soil penetration resistance (SPR) is one of the major indicators of soil physical properties. Crop residue managements, tillage practices and their interactions exert significant effects on the SPR. However, rare information is available in the sloping farmland of Mollisols. Field experiments were conducted to investigate the variations of the SPR as affected by crop residue managements and tillage practices on the sloping land in Northeast China from 2015 to 2019. The split-plot experiment was arranged with two crop residue managements (removed, REM and retained, RET), and three tillage practices (no tillage, NT; rotary tillage, RT; plow tillage, PT). SPR data in 0-80 cm soil depth was measured at the end of harvest of maize monoculture. Results showed that the two crop residue managements induced significant variations in the SPR at 0-15 cm, 15-30 cm and 0-80 cm soil depths under NT, RT, and PT treatments, respectively. In comparison with RET treatment, the average values of the SPR under REM treatment were 10.9% and 8.9% higher in 45-60 cm and 60-80 cm soil depths, respectively. The average values of the SPR under PT treatment were 12.4% and 14.1% lower in 0-15 cm soil depth, and 23.9% and 10.4% lower in 15-30 cm soil depth than those under NT and RT treatments. However, the average value of the SPR under PT treatment was 11.2% and 22.0% higher in 60-80 cm soil depth than those under NT and RT treatments, respectively. The SPR generally decreased with the slope position declined in the deeper soil depth (except for the NT+RET treatment). The findings from this research can provide a scientific reference for the establishment of rational cultivation and the sustainable development of productivity on the sloping land of Mollisols in cold regions.
