Agrowaste bioconversion and microbial fortification have prospects for soil health, crop productivity, and eco-enterprising

Abstract

Purpose Agricultural chemicals either used as nutrient inputs for soil fertility or pesticides are creating physicochemical and biological deterioration of the soils and disturbing the agro-ecosystems worldwide. Alarming concerns towards integrated agroecology demand for renewed interest in low-external input-based farming practices. These practices comprise strengthening of soil biological properties, recycling of inherent soil minerals and reuse of agricultural residual wastes. Methods We described approaches for the bioconversion of agricultural residual wastes into value-added compost. The process involves conversion of residual waste into raw compost followed by its fortification with beneficial decomposer microorganisms to produce quality fortified compost product. Finally, incubation of fortified compost with single or consortia of beneficial microorganisms like N-fixers, P-solubilizers or K-mobilizers and biocontrol agents further enriches compost to produce bioorganic products.

Effects of Bioorganic Fertilizers on the Leaf Antioxidant Enzyme Activity and the Photosynthetic Characteristics of Replanted Szechuan Pepper, Zanthoxylum simulans

“…It is well known the trace element content in soil is relatively low, but has a crucial role in regulating the growth, development and metabolism of plants [39]. It can be inferred from the experimental results, the application of appropriate amounts of bio-organic fertilizer can improve the aeration and porosity of the soil, significantly increasing the content of organic matter and inorganic elements in the soil and, as a result, promoting the growth of crops to a certain extent [40]. Overall, these results suggest that the application of organic fertilizer can promote the photosynthesis of Z. simulans.…”

Appraisal for organic amendments and plant growth‐promoting rhizobacteria to enhance crop productivity under drought stress: A review

“…The addition of compost to the soil not only improves the soil organic matter but also increases the amount of available macro‐ and micro‐nutrients for crop growth (Ditta, Imtiaz, et al., 2018; Ditta, Muhammad, et al., 2018; Singh, Singh, et al., 2019; Somerville et al., 2019). Regarding the biological properties of soil, organic amendments improve the microbial activities and their diversity in soil, thereby improving nutrient release for crop growth and productivity (Singh, Prabha, et al., 2019).…”

“…Residues of agricultural wastes such as straws, nutshells, fruit peels, fruit seeds, stoves and green leaves are among the primary raw materials for the production of BC and compost (Ditta, Muhammad, et al., 2018; Singh, Prabha, et al., 2019). The disposal methods currently being used to manage these residues are a source of extensive environmental pollution.…”

Thermoxylanolytic and Thermosaccharolytic Potential of a Heat Adapted Bacterial Consortium Developed From Goat Rumen Contents

“…With a rampant increase in agro-industrial activities, large quantities of agro residues are being generated worldwide. Such biomass being inexpensive and rich in polysaccharides (cellulose and hemicelluloses) can be subjected to microbial deconstruction (Singh et al, 2019) and the fermentable monosaccharides released can act as building blocks for value added products, such as chemicals, biofuels, etc (Aggarwal et al, 2017).…”
