“…The fine silt and clay particles facilitate formation of organo‐mineral complexes and save C from microbial oxidation (Grigal & Berguson, ). In effect, SEF values on flat ridges under bun cultivation are twofold higher than those measured under monocropping on more fertile Entisols and Alfisols in India (Pal et al, ; Panwar et al, ) and similar to those in naturally growing forest Alfisols in Amazonia (Lu et al, ).…”

“…The SEF index was developed to assess various soils' fertility status under succession of secondary tropical forest in the Amazon region of Brazil (Lu, Moran, & Mausel, ). The suitability SEF to evaluate soil degradation was also verified in different regions of India (Pal, Panwar, & Bhardwaj, ; Panwar, Pal, Reza, & Sharma, ). The equation of SEF is expressed as (Lu et al, ):

SEF = ([], normalK + Ca + Mg - log ((), 1 + Al)) * OM + 5 .

Impact of topography and sedentary swidden cultivation on soils in the hilly uplands of North‐East India

et al. 2018

A hilly catchment (4 km2) was selected to quantify the changes in physico‐chemical soil properties when traditional shifting cultivation is converted to sedentary swidden cultivation (elements of slash and burn cultivation with short fallow period), locally called bun (cropping in rows of raised beds formed from soil), in the central part of the Meghalaya Plateau. Assuming that the monsoonal climate, deep‐weathered granites, and time are relatively uniform over the small catchment, the differences in soil were compared on two contrasting landforms (flat ridges and steep slopes) and three land use types (natural deciduous forest, sedentary swidden cultivation of potatoes, and fallow land with pine forest) within each landform. In contrast to previous studies in region, soil fertility indices calculated in the present study indicated that the bun system can also improve soil quality. Soil response significantly varied at spatial scales, however, and in terms of the possibility of continuing sustainable cultivation in the future. At a local scale on flat terrain upon granites, soil under swidden cultivation had the higher fertility indices, than fallow land and natural forest, whereas steep slope cultivated soil had the lowest fertility indices, following fallow land and natural forest. Therefore, bun system can be efficient in tropical regions with gentle terrain and limited forest resources. At a regional scale, low potato yield combined with a growing food demand forces farmers to expand potato cultivation on steep slopes, the dominant landform in the Meghalaya, increasing the risk of soil degradation. Introducing agroforestry with pine trees into bun cultivation can mitigate the rates of soil degradation on steep slopes.

“…Many countries throughout the world are facing acute scarcity of lands for food production due to the rapid increase of population and limited land resources, which causes people to convert forestland into agricultural, horticultural, plantations, and pastoral land for cattle settlements or mining [1]. Such human activities have led to the depletion of existing forests throughout the world, particularly in Asian countries.…”

A study was conducted to determine the status of soil properties after enrichment planting in comparison to an adjacent secondary forest and to evaluate the effect of enrichment planting of Shorea macrophylla (de Vriese) on the soil fertility status with special reference to Soil Fertility Index (SFI) and Soil Evaluation Factor (SEF) at Sampadi Forest Reserve, Sarawak. The study sites were stands rehabilitated in different years (1996: SM96; 1997: SM97; 1998: SM98; 1999: SM99) and secondary forest (SF). Findings indicated that the soils at rehabilitation sites and SF were strongly acidic in nature, with pH less than 5.50, poor soil exchangeable bases, and nutrient status. The soils were relatively of sandy clay loam to sandy clay. Principal Component Analysis revealed the three most significant components of the soil properties which explained 76.3% of the total variation. At surface soils, SFI was correlated with tree growth parameters of S. macrophylla, indicating that SFI is an applicable soil quality index as compared to SEF. Notwithstanding, a significant association was found between soil available phosphorus and planted S. macrophylla, indicating that soil phosphorus is a better indicator than SFI. Further studies on other environmental factors influencing tree growth performance, early establishment of experimental reforestation at nursery, and field should be implemented to obtain the initial data on seedling growth performance prior to outplanting.

“…Abiotic stress induced by heavy metals also exerts a negative influence on the biological activity (Khan et al 2007;Pan and Yu 2011) and biochemical parameters of soil (Kucharski et al, 2011;Wyszkowska et al, 2013a, Wyszkowska et al, 2013bEpelde et al, 2014;Aghababaei et al, 2014), which are closely correlated with soil fertility (Mijangos et al, 2009). For this reason, microbial biomass (Panwar et al, 2011), dehydrogenases activity and ammonification activity are considered to be the most reliable indicators of changes in the soil environment.…”

This study makes a pioneering attempt to analyze the neutralizing effects of algae extracts and basalt flour on cadmium-contaminated soil with the aim of restoring a healthy soil balance. Their effectiveness was compared with that of straw and compost.The following soil parameters were determined to evaluation of changes in a cadmiumcontaminated environment: dehydrogenases and catalase activity, population size of microorganisms. The influence of cadmium on the resistance of spring barley crops was evaluated. Cadmium was applied at doses of 0, 4, 40, 80, 120, 160, 200 mg Cd 2+ kg -1 DM soil.The results of the experiment indicate that algae extract was a less effective soil amendment, whereas basalt flour failed to improve the soil profile. Straw and compost significantly
