“…Overall, the macroarthropod community and plant status in C. juncea, B. decumbens and P. glaucum plots were characterized by a low abundance or even absence of some predators (e.g.,. Araneae -Filistatidae, Coleoptera -Carabidae, Dermaptera -Forficulidae, Scorpiones -Scorpionidae), absence of herbivores (e.g., Thysanoptera -Thripidae, Hemiptera -Cercopidae, Orthoptera -Grylloidea, Homoptera -Membracidae), and high abundance of decomposers (e.g., Diptera -Muscoidea) and ecosystem engineers (e.g., Hymenoptera -Formicidae) which created a negative effect in the trophic structure by disrupting some important ecological process such as biological control, mutualism, parasitism and nutrient cycling Freitas 2017, 2018;Zhang et al 2018;Mishra et al 2017).…”

Soil macroarthropods are organisms considered as key factors to sustain soil quality and sustainability due to their services to soil ecosystem. The community structure and seasonal variation of soil macroarthropods in 5-year cultivation of green manure plant species in the Brazilian semi-arid, Areia, Paraiba, Brazil were investigated between June and December 2018. Soil samples and macroarthropod specimens were collected using soil cores and Provid-type traps, respectively, during rainy and dry seasons. We characterized both soil chemical properties and macroarthropod community under ten green manure plant species: Brachiaria decumbens Stapf. cv. Basilisk, Canavalia ensiformis (L.) DC, Crotalaria juncea L., Crotalaria ochroleuca G. Don, Crotalaria spectabilis Roth, Lablab purpureus (L.) Sweet, Mucuna pruriens (L.) DC., Neonotonia wightii (Wight & Arn.) J.A. Lackey, Pennisetum glaucum L., and Stilozobium aterrimum Piper & Tracy. The highest values of richness, diversity and dominance in the macroarthropod community during the rainy season were found on the plots where C. spectabilis and M. pruriens were cultivated, whereas during the dry season the highest values were found in the plots where C. ochroleuca, C. spectabilis, and S. aterrimum were cultivated. In the plots where B. decumbens and P. glaucum where cultivated, we found lower values of richness, diversity, and dominance in the macroarthropod community compared to the leguminous plant species during rainy and dry seasons. Our findings suggest that: 1) green manure practice and seasonality changed soil macroarthropod community, trophic structure, and ecological processes in semi-arid conditions; and 2) abundance of predators, ecosystem engineers, decomposers and herbivores was promoted by plant species from Fabaceae family. The results highlight the importance to consider plant species from Fabaceae family as habitat and food resources for soil fauna community.

“…An index of soil quality was calculated using the PCA-LSF-SQIw approach, described by Mishra et al (2017), which combines soil physical and chemical characteristics, plant biomass production, and soil macroarthropod community measured at all studied plots. Based on this approach we developed a model (Eq.…”

Soil salinity and acidity are some of the major causes of land degradation and have a negative impact on agricultural productivity. Assessing soil quality (SQ) of soils affected by soil salinity and acidity is required for their sustainable utilization for agricultural production. The aim of the present study was to evaluate the SQ of the salt-affected acid soils of the Indian West Coastal region using the additive and weighted soil quality indices (SQIs). The SQIs were developed using a total dataset (TDS) and a minimum dataset (MDS). The TDS comprised of 15 different soil properties as electrical conductivity (EC), pH, bulk density, soil available nitrogen (N), phosphorus (P), potassium (K), sulfur (S), boron (B), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) and exchangeable calcium (Ca), magnesium (Mg), and sodium (Na) measured on 300 soil samples (depth 0-0.15 m). Based on principal component analysis and correlation analysis, an MDS with soil properties like soil pH, EC, Na, Cu, Mn, and BD was formed. Using two approaches (additive and weighted), two datasets (TDS and MDS), and two scoring methods (linear and nonlinear), eight SQIs were developed. The MDS-based linear weighted and non-linear weighted SQI found suitable to evaluate SQ of salt-affected acid soils and SQI had a significant and negative correlation of − 0.83 and − 0.70 (p < 0.01) with EC, respectively. Thus, it is clear that the SQ considerably reduces with an increase in soil salinity. The performance of the MDS-based SQIs was better than the TDS to discriminate different soil salinity classes. The agreement between the linear and non-linear scoring method of SQI had a linear relationship with a coefficient of determination (R 2) of 0.91-0.96. Thus, assessing the SQ of saltaffected acid soils using MDS, linear scoring, and weighted approach of the soil quality indexing could save the time and cost involved.

“…Studies on shifting cultivation are mostly confined to the assessment of soil quality, nutrient, organic carbon, and erosion status under such land use and their comparison with different land-use systems, particularly forest (Biswas et al, 2012;Fonte et al, 2010;Gafur et al, 2003;Giardina et al, 2000;Mishra et al, 2017;Tanaka et al, 2005;Teegalapalli et al, 2018). However, comprehensive studies on agricultural land-use planning vis-à-vis soil resource information on shifting cultivated areas are lacking.…”

Shifting cultivation, soil degradation, and agricultural land‐use planning in the northeastern hill region of India using geo‐spatial techniques

et al. 2021

Shifting cultivation is widely practiced in the northeastern hill (NEH) region of India. It is known that the destruction of natural forests and its conversion to cropland leads to soil resource degradation. The impacts on soil due to jhuming (jhum practice followed in shifting cultivation) have not been studied adequately. Also, study of alternatives to jhum land use is lacking. In our study, a soil resource inventory of jhum lands was generated for a part of the Purvanchal Ranges of Eastern Himalaya, India to ascertain the nature of soil resource degradation due to jhuming using geo‐spatial techniques. High‐resolution IRS P6 LISS‐IV and stereo‐pair CARTOSAT‐I satellite images along with digital elevation model data were used to map soil resources of jhum lands through a detailed soil survey. Typical pedons were also studied in the native forest adjacent to the jhum lands. Further, land suitability evaluation of the identified soil series for crop growth was carried out to propose alternative land‐use models for jhum lands distributed over different landforms. Results indicated that soils of jhum lands were organically degraded and followed regressive pedogenesis, whereas forest soils followed progressive pedogenesis, particularly on high (650–1250 masl) and medium hills (250–650 masl). Alternaive land‐use models with the inclusion of upland rice and without the inclusion of rice have been proposed. Results of the investigation should be useful for policy makers to seeking make the best use of the land resources under jhum cultivation.
