“…It is an effective way to substitute inorganic fertilizers, using the tank silt as an organic amendment; it also improves soil quality and improves moisture stress resilience during mid‐season dry spells which can enhance crop productivity in rainfed agriculture areas (Balamatti & Chandra, 2018). Many studies have shown that the addition of tank silt has improved soil available water content by 70%–94% and moisture retention capacity by 4 to 7 days, which has played a vital role during intermittent dry spells and droughts (Dey et al, 2019; Srinivasarao et al, 2021).…”

“…Meeting the food demands of the projected population is a challenge that will increase pressure on natural resources particularly land resources. In contrast, great pressure is created due to improper utilization and depletion of land resources that leads to degradation (Srinivasarao et al, 2021). The estimated average global topsoil loss is around 0.7%.…”

Nature‐based solutions in soil restoration for improving agricultural productivity

Soil is a living and dynamic body, which is prone to degradation under conventional agricultural practices. Healthy soil is one of the most important pillars of sustainability as it delivers several ecosystem services along with its control on microbial activity, nutrient recycling, and decomposition. Nature‐based solutions can play an important role in restoring soil quality for enhanced agricultural productivity and sustainability. This article discusses various nature‐based options available for improving soil quality. Indigenous practices such as sheep penning, tank silt application, green manuring, and refuse from croplands and households have the potential to restore and maintain soil fertility. Biofertilizers can add nutrients (N fixers), fixe up to 300 kg N ha through biological nitrogen fixation (BNF) and facilitate (nutrient solubilizer and mobilizers) nutrient availability in the soil. Biochar, a commonly used product, can increase soil moisture availability by 8%–10% and aids in mitigating climate change through C‐sequestration. Biochar may have a climate change mitigation potential of 1.8 Pg CO2‐C equivalent per year. When added to the soil, it not only acts as a nutrient source; but also acts as a soil amendment. Biogas slurry, the effluent from biogas reactors, contains various nutrient elements that can enrich soil fertility. The holistic approach in a farming system, through integration of different enterprises, reduces dependence on off‐farm resources. Soil management through nature‐based options will maintain crop productivity and sustainability in the long run without any adverse effects on the environment.

“…The nutrient discrepancy in the plant is a common occurrence found in degraded land, and among different plant nutrients, iron is the essential ingredient for plant growth (Connorton et al, 2017 ). Rapid industrialization, urbanization, unsuitable land use (IPBES, 2018 ), fast agricultural practices (Keesstra et al, 2018 ), soil salinization (Edrisi et al, 2021 ), soil erosion (Paul et al, 2020a , b ), invasion of alien species (Rai, 2021 ), poor governance management strategy (Gerber et al, 2014 ), overexploitation of natural resources, excessive mining (Upadhyay and Edrisi, 2021 ; Shakeel et al, 2022 ), etc., degrade more than 33% of global land resources through direct and indirect approaches (IPBES, 2018 ; Srinivasarao et al, 2021 ).…”

Plant growth performance under a stressful environment, notably in the agriculture field, is directly correlated with the rapid growth of the human population, which triggers the pressure on crop productivity. Plants perceived many stresses owing to degraded land, which induces low plant productivity and, therefore, becomes a foremost concern for the future to face a situation of food scarcity. Land degradation is a very notable environmental issue at the local, regional, and global levels for agriculture. Land degradation generates global problems such as drought desertification, heavy metal contamination, and soil salinity, which pose challenges to achieving many UN Sustainable Development goals. The plant itself has a varied algorithm for the mitigation of stresses arising due to degraded land; the rhizospheric system of the plant has diverse modes and efficient mechanisms to cope with stress by numerous root-associated microbes. The suitable root-associated microbes and components of root exudate interplay against stress and build adaptation against stress-mediated mechanisms. The problem of iron-deficient soil is rising owing to increasing degraded land across the globe, which hampers plant growth productivity. Therefore, in the context to tackle these issues, the present review aims to identify plant-stress status owing to iron-deficient soil and its probable eco-friendly solution. Siderophores are well-recognized iron-chelating agents produced by numerous microbes and are associated with the rhizosphere. These siderophore-producing microbes are eco-friendly and sustainable agents, which may be managing plant stresses in the degraded land. The review also focuses on the molecular mechanisms of siderophores and their chemistry, cross-talk between plant root and siderophores-producing microbes to combat plant stress, and the utilization of siderophores in plant growth on degraded land.

“…Saline areas occur in at least 100 countries and cover 932.2 Mha worldwide ( Cuevas et al, 2019 ). Soil salinization may result from human activities, such as improper irrigation, deforestation and intensive cropping, and natural factors, e.g., mineral weathering and soil derived from salt-affected rocks ( Athar and Ashraf, 2009 ; Srinivasarao et al, 2021 ). Due to the level of salinity, soils have been divided into non-saline (ECe 0–2 dS/m), slightly saline (ECe 2–4 dS/m), moderately saline (ECe 4–8 dS/m), strongly saline (ECe 8–16 dS/m), and extremely saline (ECe > 16 dS/m) ( Corwin and Scudiero, 2019 ).…”

Pseudomonas stutzeri and Kushneria marisflavi Alleviate Salinity Stress-Associated Damages in Barley, Lettuce, and Sunflower

Soil salinity is one of the most important abiotic factors limiting plant productivity. The aim of this study was to determine the effect of selected halotolerant plant growth-promoting endophytes (PGPEs, Pseudomonas stutzeri ISE12 and Kushneria marisflavi CSE9) on the growth parameters of barley (Hordeum vulgare), lettuce (Lactuca sativa), and sunflower (Helianthus annuus) cultivated under salt stress conditions. A negative effect of two higher tested salinities (150 and 300 mM NaCl) was observed on the growth parameters of all investigated plants, including germination percentage and index (decreasing compared to the non-saline control variant in the ranges 5.3–91.7 and 13.6–90.9%, respectively), number of leaves (2.2–39.2%), fresh weight (24.2–81.6%); however, differences in salt stress tolerance among the investigated crops were observed (H. annuus > H. vulgare > L. sativa). Our data showed that the most crucial traits affected by endophyte inoculation under salt stress were chlorophyll concentration, leaf development, water storage, root development, and biomass accumulation. Thus, the influence of endophytes was species specific. K. marisflavi CSE9 promoted the growth of all tested plant species and could be considered a universal PGPEs for many plant genotypes cultivated under saline conditions (e.g., increasing of fresh weight compared to the non-inoculated control variant of barley, lettuce, and sunflower in the ranges 11.4–246.8, 118.9–201.2, and 16.4–77.7%, respectively). P. stutzeri ISE12 stimulated growth and mitigated salinity stress only in the case of barley. Bioaugmentation of crops with halotolerant bacterial strains can alleviate salt stress and promote plant growth; however, the selection of compatible strains and the verification of universal plant stress indicators are the key factors.
