“…This can be explained by the positive role of vermicompost in increasing the activity of beneficial microorganisms and improving the soil structure. On the other hand, vermicompost increased the water retention capacity leading to a higher nutrient availability and uptake (Coulibaly et al 2018;Sarma et al 2018). Therefore, the results confirm that crop productivity was affected by cropping patterns and nutrient uptake.…”

Only a few studies have hitherto investigated the effects of the application of organic fertilizers in intercropping systems on the plant essential oil (EO) productivity. Hence, this work has aimed to study the effect of different intercropping patterns on EO quality and quantity of sweet basil (Ocimum basilicum L.) under vermicompost application. In the present study, the cropping patterns consisted of 1B:1CB, 2B:2CB, 3B:2CB, and 4B:2CB (basil: common bean) as well as the pure culture of both crops and fertilizer treatments including usage or non-usage of vermicompost. The maximum seed yield of common bean (2786 kg ha −1) and dry matter yield of basil in the first (261.5 g m −2) and second harvests (214.7 g m −2) were recorded in the pure cultures fertilized with vermicompost. In addition, the nutrient uptake rate of macronutrients and micronutrients in both plants after application of vermicompost improved in intercropping patterns. In both harvests, the maximum EO content of basil (0.84% in the first harvest and 0.69% in the second harvest) was observed at the cropping ratio of 3B:2CB fertilized with vermicompost. Chemical analysis, achieved by GC-MS, evidenced 1,8-cineole, linalool, methyl chavicol, α-trans-bergamotene, methyl eugenol, and epi-α-cadinol as the main basil EO constituents in both harvests. The highest increment level for most ofEO constituents, nutrient uptake, and land equivalent ratio (1.52) were obtained in the intercropping pattern of 3B:2CB fertilized with vermicompost. In general, the intercropping pattern of 3B:2CB after use of vermicompost can improve the EO productivity and quality of basil. This intercropping pattern was accompanied by the increment of nutrient uptake. Therefore, this treatment can be introduced as a valid and sustainable strategy to replace chemical fertilizer and plant monoculture.

“…Giacomini et al [10] observed a higher C mineralization rate under residue incorporation than surface application. Sarma et al [7] observed higher cumulative CO 2 emission with the addition of organic amendments, and the highest increase was associated with vermicompost incorporated into soil. A higher C mineralization rate was observed under MWMb i treatment than surface application.…”

“…Crop residues serve as a source of nutrients, help in maintaining soil organic carbon (SOC) and subsequently improve overall soil quality [4]. Release of essential nutrient elements in soil as well as emission of CO 2 into the atmosphere are controlled by the mineralization of organic matter in soil [5][6][7], making it the most important process occurring in soil. In India, to improve the productivity of the rice-wheat cropping system there is no doubt that an adequate and balanced supply of essential nutrients is of critical concern.…”

Carbon mineralization in soil as influenced by crop residue type and placement in an Alfisols of Northwest India

Carbon (C) mineralization of crop residues is an important process occurring in soil which is helpful in predicting CO 2 emission to the atmosphere and nutrient availability to plants. A laboratory experiment was conducted in which C mineralization of residues of rice (Oryza sativa), wheat (Triticum aestivum), maize (Zea mays), mungbean (Vigna radiata) and their mixtures was applied to the soil surface or incorporated into an Alfisols from Northwest India. C mineralization was significantly affected by residue placement and type and their interactions. Rice residue had a higher decomposition rate (k ¼ 0.121 and 0.076 day À1) than wheat (0.073 and 0.042 day À1) and maize residues (0.041 day À1) irrespective of placements. Higher decomposition rates of rice and wheat were observed when placed on soil surface than incorporated in the soils. Additive effects of the contribution of each residue type to C mineralization of the residue mixture were observed. When mungbean residue was added to the rice/wheat or maize/wheat mixture, decomposition of the residue mixture was enhanced. Crop residues with low N and high C/N ratio such as maize, wheat, rice and their mixtures can be applied on the soil surface for faster C and N mineralization, thereby helping to manage high volumes of residues under conservation agriculture-based practices in northwest India.

The soils of South Asia provide food to almost 1.8 billion people but are prone to many sustainability issues. The ever-increasing population has put enormous pressure on the available natural resources (land/soil and water), which is threatening future food security. The fertile farmlands are being encroached by urbanzation. Declining groundwater levels, increasing micronutrient deficiencies, the use of fertile soil for brick making, degrading soil structure, and global warming are serious sustainability issues in South Asia. The extensive production of cereals and conventional soil management practices are increasing soil erosion; depleting soil organic matter, soil fertility, water resources, and increasing salinization. The restoration and management of soil organic matter, rainwater harvesting, and the efficient use of water and sustainable nutrient management are essential to sustain the long-term productivity of agricultural soils. Diversification of monocropping systems and the adoption of conservation agriculture may enhance the sequestration of soil carbon and increase biodiversity. However, site-specific technologies must be identified and made available to farmers. Prime agricultural land must be protected against urban encroachment. Communication and collaboration between scientists, farmers, and policymakers are needed to manage soils for ensuring food security in South Asia. The objective of this review is to deliberate the causes of soil degradation in South Asia and suggest soil management options to reverse the degradation trends and ensure long-term food security in the region.
