“…Previously many authors, i.e. Romaniuk et al (2014), Gong et al (2015), Raiesi and Kabiri (2016), and Vasu et al (2016) create a broader linkage between soil quality and sustainability using soil quality indexing approach fruitfully. Among them, soil quality test kits (Sarrantonio et al 1996;SQTKG 1999), farmer-based scorecards (Romig et al 1996) and soil resource management programs (Walter et al 1997) focus on farmerbased evaluations regarding soil management practices and their effects on soil.…”

Background: The present study introduces an alternate tool of laboratory analysis named Soil Health Card (SHC) for soil quality monitoring and routine field observations by farmers.Results: Different physicochemical and nutrient contents of soil, i.e. pH, electric conductivity, soil organic matter, organic carbon, total nitrogen, phosphorous, sulfur and boron were assessed by laboratory analysis collected from the different fields of Noakhali district of Bangladesh. These parameters were scored according to the soil fertility standards according to Bangladesh Agriculture Research Council. Results found that, the soil quality of all the studied fields are medium category. Again, a SHC was prepared using soil structure, subsurface compaction, aggregate stability, status of ground cover, soil smell, soil pH, color, organic matter content, drainage capacity, diversity of micro-life, earthworm contents, infiltration rate, soil aeration, crop coverage and leaf color. The result of SHC is interestingly similar to the laboratory experiment results. Conclusions:Analyzing these two methods it was found that, the SHC is truly representative, much convenient, precise, coast effective and easily understandable to the marginal farmers. However, SHC can be an alternative to farmer for sustainable farm management.

“…The highest amount of DM was obtained using C. juncea. Crops remains must cover at least 50% of the soil surface or maintain at least 6 t ha -1 of dry matter to achieve a good coverage rate (Alvarenga et al, 2001;Raiesi and Kabiri, 2016;Vasu et al 2016). In this study, the amount of residues on the soil surface is close to or higher than this value.…”

The use of cover crops is a strategy to maintain the productive capacity of agricultural soils. The increase of organic carbon content, nutrient cycling and, consequently, the increase in soil fertility are some of the greatest benefits. This study evaluated the chemical attributes of the soil after the use of cover crops species in the Cerrado region of Piaui. The experiment was carried out from January 2015 to July 2016. It was performed in a completely randomized block design with eleven treatments and four replicates. ), potential acidity (H + Al), soil organic carbon (OC), the saturation of bases (V%), saturation by aluminum (m%) and effective CEC were measured. Fifteen months after their establishment, cover crops positively influenced the levels of P, K and OC with no changes in the other chemical properties. The OC contents were higher with the use of C. cajan -cv. 'fava larga', brachiaria and C. ochroleuca + millet, mainly in the topsoil. C. espectabilis, spontaneous vegetation, M. aterrima, brachiaria and C. ochroleuca were the most efficient in K cycling.

“…But the development of subsoil sodicity under rainfed conditions is due to the complex hydrological behaviour of the soils. The major soils under present study are Alfisols, Vertisols, and Inceptisols and their hydrological behaviour differ markedly (Pathak, Sudi, Wani, & Sahrawat, ; Vasu et al, ; Vasu et al, ).…”

“…The pH of Typic Haplustalfs and Typic Rhodustalfs were slightly acidic to neutral due to low base saturation of these highly weathered soils whereas the high concentration of Na + in the soil exchange complex resulted in high pH in Haplusterts and Haplustepts. OC plays a vital role in determining soil structure, nutrient availability, and water holding capacity (Lal, ; Vasu et al, ). In the present study, the low OC content of the soils is due to rapid mineralization of organic matter because of the semiarid climate, poor vegetative cover, and less addition of leaf litter and organic manures under rainfed cultivation.…”

A conceptual model of natural land degradation based on regressive pedogenesis in semiarid tropical environments

Land degradation occurs in all the climatic regions, however, the adverse effects are more pronounced in the semiarid tropical (SAT) environments due to increasing aridity and water scarcity. Though natural processes can also cause land degradation, it is generally attributed to anthropogenic factors. In this study, we elucidate the role of climate and landscape driven soil forming processes in land degradation through a conceptual model. For this, morphological, physical, and chemical properties of the soils occurring in a part of the SAT Deccan Plateau region, India, were characterized. The trend of climatic variables, namely, the mean annual rainfall, potential evapotranspiration, and maximum summer temperature during the last century (1901–2010) showed that the increase in aridity negatively influenced the soil forming processes. The results showed that rainfall variability, temperature, potential evapotranspiration, and hydrological behaviour of the SAT soils were the primary drivers of the soil forming processes and they were identified through examination of the soil variability by factor analysis. The depth distribution of selected indicators (% clay, pH, calcium carbonate, exchangeable sodium percentage, exchangeable magnesium percentage, and hydraulic conductivity) indicated that the current pedogenic processes operating in the SAT environment caused the undesirable modification in soil properties. Through our conceptual model, we discuss the mechanism of the formation of pedogenic carbonate, subsoil sodicity, and subsequent reduction in hydraulic conductivity which leads to the land and vegetation degradation in the SAT environments.
