“…The climate is the mid-temperate continental monsoon climate, with an annual average temperature of 0 • C and a large temperature difference between winter and summer. Annual precipitation is around 534 mm, and 90% precipitation occurs in May to September [49]. The primary soil type in this area is Mollisols (also called Black soils), accounting for 64.2% of the total area.…”

“…The under layer has a heavy clay texture, poor structure, and low water permeability. These properties allow runoff to form readily in the surface layer, not only resulting in the loss of soil nutrients, but also in damage to the soil's physical properties, and weaken the soil infiltration capacity [49,53]. Soybean is one of the most important summer crops in this area, with a water requirement of 370 to 540 mm [54], which is sown in early May and reaped in late September.…”

“…Soybean as a native of China and one of the most important crops in the country, has been known to man for over 5000 years [48], and 56% of China's total soybean production was provided in northeastern China [49]. The agriculture in northeastern China is critically dependent on rainfall and water use efficiency [16,18,50], and rainfed crop production is subject to frequent fluctuations in precipitation [51].…”

Soil erosion could change the effective storage of soil moisture and affected crop water use efficiency (WUE). To quantitative study differences in the WUE of soybean and the crop’s response to water stress for soils with different degrees of erosion in northeastern China, three erosion degrees—(1) lightly, (2) moderately and (3) severely—eroded black undisturbed soils and four years (from 2013 to 2016) of soybean pot experiments were used to control soil water content (100%, 80%, 60%, and 40% field capacity (FC)) and observe the crop growth processes. To study the relationships between erosion–water use–productivity, the following results were achieved: (1) the optimal water content was 80% FC for lightly eroded soil (L) and 100% FC for both moderately (M) and severely (S) eroded soil. Yield (Y) was best in M with the value of 3.12 t ha−1, which was 4.6% and 85.5% higher than L and S, respectively. Under the conditions of adequate water supply, there was no significant change in Land M, but the values were significantly different for the S ( p < 0.05). (2) Y and biomass (B) were sensitive to water stress except in the branching stage. (3) The values of WUEY and WUEB for the three eroded soils were the best at 80% FC. The stress coefficient (SF) values of the three eroded soils were not significantly different. In the flowering and pod formation stage, the SF reached the maximum under waterlogging stress. While the water shortage stress reached the maximum in the seed filling stage, the soil water content decreased by 10%, and the WUEB decreased by 15%, which was 2.5 times more powerful than the waterlogging stress. This study indicated the change in soybean growth with respect to the water response caused by soil erosion, and provided a scientific basis and data for the reasonable utilization of black soil with different erosion intensities. The results also provided important parameters for the growth of simulated crops.

“…2), because biomass production at this growth stage was essential to maize yield formation (Russo et al, 2004;Herrmann et al, 2013). Similarly, Lin et al (2019) found that there was no difference in soybean yield between "light" and "moderate" erosion sites, but 11% of yield loss was observed in maize grown in the "moderate" erosion sites. These results demonstrated that the increasing soil erosion reduced crop productivity and the reduction magnitude might be dependent of crop species (Bakker et al, 2007;Gao et al, 2015;Lin et al, 2019).…”

We established three simulated erosion severities with topsoil depths of 10, 20 and 30 cm in a Mollisol farmland under a maizesoybean rotation system with no-tillage. After three consecutive years of field experiment, the decrease in topsoil thickness from 30 to 10 cm resulted in 9-22% of decrease in maize yield but not soybean. Compared to the 30 and 20-cm topsoil thickness, the 10-cm topsoil significantly lowered root and shoot biomass of maize at the jointing (V7) and milk stages (R3) and of soybean at the mid-seed filling stage (R6). Compared to the 30-cm topsoil, the 10-cm topsoil decreased available nitrogen and phosphorus in soil by 42% and 36% under maize, and by 25% and 19% under soybean, respectively, while the shallow topsoil also decreased N, P and K uptake per unit root length with the decreases being less for maize than soybean. Compared to the 30-cm topsoil, the 10-cm and 20-cm topsoil significantly increased the activities of urease, phosphatase and invertase in maize-grown soil, but not in soybean-grown soil except for the activity of urease in 10-cm topsoil. Maize was more sensitive to soil erosion than soybean due to the greater decreases in soil nutrient availability and its capability of nutrient uptake. The greater stimulation of nutrient mineralization processes in soil did not alleviate the nutrient constraint to maize yield under severe erosion conditions.

“…OIL erosion is one of the main forms of land degradation and according to recent estimations about 25% of the worldwide arable land is degraded [1]. Soil erosion is the accelerated loss of the arable layer due to the transportation of the soil particles to other sites [2] and it is a product of a combination of the erosive potential of the rainfall, vegetation cover, topography, and soil texture; it is highly related to crop productivity, food security [3]- [4], and to the generation of floods in lowlands [5]- [6].…”

In this work, we apply close-range photogrammetry with unmanned aircraft systems to quantify erosion with millimetric spatial resolution in agricultural plots. We evaluate the proposed methodology against the traditional runoff method on active plots. A database of digital elevation models was constructed with a ground sampling distance of 7 mm/pixel and maximum root-mean-square total error of 4.8 mm, which allowed the follow-up of soil erosion dynamics within the runoff plots for a period of three months. Good agreement of the photogrammetric estimations with respect to field measurements was observed, whereas it provides a more detailed spatial information that can be used for precise soil loss dynamic studies.
