“…In the same experimental area, Mota et al [6] observed that porosity-based indicators did not correlate with grain yield, but the pore size distribution indicator and organic carbon were effective in distinguishing the cropping systems. Silva et al [16], in the same experimental area, observed that soil and water losses were negatively correlated with crop yield and vegetation cover rate. Therefore, these findings and the absence of differences in porosity-based indicators further reinforces the role of vegetation cover as a key factor in controlling the erosive process.…”

“…Considering the study area formed by a large experimental block, a completely randomized design was adopted, as recommended by Ferreira et al [28] and successfully used in previous studies of long-term field experiments [29,30] and also in the same experiment in anterior studies [6,16,31]. Thus, for soil losses, water losses, penetration resistance, total porosity, macroporosity, microporosity, and soil bulk density, the different cropping systems (seven treatments) were evaluated.…”

“…The predominant climate in the region is humid subtropical (Cwa) according to the Köppen classification, with an average annual temperature of 20 • C and mean annual rainfall of 1416 mm [15], mainly concentrated from October to April (Figure 1). This region has a characteristic dry season with frequent occurrence of dry spells during the rainy season [16].…”

Many researchers have reported relationships of physical and chemical properties with water erosion; however, little is known about microbiological properties in this context. Thus, the aim of this study was to evaluate soil properties in relation to erosion in areas with different cropping system practices under no-tillage in the Brazilian Cerrado. The experiment has been carried out since 2014 in a Typic Haplustox under soybean (S) and maize (M) monoculture, maize/soybean annual rotation (MS), maize/brachiaria/soybean/brachiaria rotation (MBSB), two of those treatments with high input of fertilizer (MBSB-HI and MS-HI), and bare soil (BS). Soil losses were quantified in erosion plots. The design was completely randomized. The greater vegetation cover crop, provided by intercropping/succession with brachiaria, increased microbial biomass carbon. The lack of vegetation cover affected the basal soil respiration and metabolic quotient. Basal soil respiration proved to be inversely related to soil and water losses. Vegetation cover was a key factor regulating water erosion. Penetration resistance and aggregate stability correlated with soil and water losses. Thus, not only physical and chemical, but also biological properties are deeply affected by erosion, aiding in early monitoring of water erosion. Soil quality improvement in ecologically supported management contributes to mitigating erosion.

“…Other current research on soil resilience also focuses on management practices and climate regimes. These include investigating positive impacts from land management practices due to the effects of ecological intensification [44] and also research into enhanced agrisystem resilience and production stability in climate regimes [45]. Specifically in the New Zealand context, recent research includes a focus on frameworks of soil and landscape functionality which can assist in land management considerations, termed "the Land Resource Circle".…”

Using Soil Sustainability and Resilience Concepts to Support Future Land Management Practice: A Case Study of Mt Grand Station, Hāwea, New Zealand

Soil acts as the integrator of processes operating within the biological and hydrological landscapes and responds to external disturbances and processes on varying time scales. The impact of any change results in a corresponding response in the system; which is dependent on the resistance of the soil system to the disturbance. Irreversible permanent change results when the soil system shifts over a threshold tipping point; with the soil system experiencing a regime shift with associated structural and functional collapse. Climate change is the most important external disturbance or stressor on these systems due to changes in precipitation, temperature and moisture regimes. Our research at Mt Grand is focused on approaches to increasing land use resiliency in the face of environmental change. Our purpose is to select and apply soil quality indices which can be used to assess soil resilience to external disturbance events for Mt Grand Station in New Zealand. We will identify biophysical variations and landscape drivers in soil resilience; and use these results to match land management practices with variations in soil resilience. For example, soils with low resilience will only have land management practices that have a low impact on the soil resource. We selected soil attributes that represented indicators of resistance, used to quantify the capacity of a soil to recover its functionality. We mapped this soil resilience framework against a national database of soil and landscape attributes for Mt Grand Station. The output from this research is to posit a conceptual framework of soil quality indices which relates to soil resilience, and thus to create a spatial map of soil resilience for Mt Grand Station.

“…USLE is considered to produce good erosion estimates in the long term, ranging from 10 to 20 years and this modeling is still accepted and widely applied by the world until now. Paying attention to the existing critical land and increasingly widespread in the upstream of Air Bengkulu Watershed, [7] stated that it is necessary to plan soil and water conservation actions based on organic farming systems that must have a positive end result in increasing the capacity of the soil to reduce the rate of erosion, prevent the occurrence of erosion, land degradation and criticality.…”

Awareness of the dangers posed by the use of synthetic chemicals in farming attracts attention. The development of organic agriculture requires a suitable location. However, sometimes, suitable land is very limited. This study aims to select the site for the development of organic agriculture, as well as to function in overcoming the existence of critical land, especially in the Upstream of Air Bengkulu Watershed, Bengkulu. The research method carried out is by compiling a Map of Conservation Activity Plan (CAP) based on a model developed by the then Ministry of Environment and Forestry. Maps used for input to CAP are EHL (Erosion Hazard Level), Soil Depth, Slope, Population Pressure, and the Recommended Landuse. From the CAP Map, the sites that are estimated to be used for organic farming development locations will be obtained. Results show that the sites for CAP to support organic farming is divided, broadly, into 2 categories: (1) mixed cultivation, minimum tillage, planting of ground cover, management of organic matter and application of agroforestry covers 9.32% in Semidang Lagan and Karang Tinggi District, and (2) mixed cropping, minimum tillage, ground cover planting, organic matter management, permanent vegetation and application of agroforestry covers 38.79% in Taba Penanjung District, Bajak Dua, Jambu and Rindu Hati Village. While 51.89% of the study area in Taba Penanjung District should be used for protected area.
