“…Macro aggregate-associated SOC may rapidly be stabilized and decomposed due to larger size [64], as micro aggregates are strongly bound. Labile (dissolved and mineral-associated) organic carbon fractions play a conclusive role in aggregate formation and stabilization [13]. In the present study, organomicrobially treated soils had noticeably greater labile organic fractions compared with control treatments (Figures 4 and 5).…”

“…Nutrient stream, soil physical vigor, erosion protection, and biological activity are contributed by SOM [12]. Mineral fertilization secondarily increases soil carbon sequestration [13], since organics, either alone or in combination with mineral fertilizer, are more effective in improving SOM and its segments than mineral nourishment alone [14]. Artificial fertilization helps in aggregate materialization [15] and stabilization [16] augmenting spatial inaccessibility for decaying microbes [17].…”

Less precipitation, high temperature, and minimal natural vegetation are characteristic of regions having an arid climate. The harsh environment massively destructs the soil structure of that area by burning soil organic carbon, leading to deteriorated soil nutritional quality, creating a significant threat to agricultural production and food security. Direct application of organic wastes not only substitutes lost organic carbon but also restores soil structure and fertility. This study was conducted to assess the impact of organic amendments, i.e., farm manure (FM), poultry manure (PM), molasses (MO), and Exo-Poly Saccharides (EPS) producing rhizobacterial strains i.e., M2, M19, M22 amalgams as treatments. To assess the impact of treatments on soil carbon and structure restoration to hold more water and nutrients, a 42-day incubation experiment using a completely randomized design (CRD) under the two-factor factorial arrangement was conducted. Macro aggregation (0.25 to >1 mm), carbon retention in macro aggregates, active carbon (dissolved organic carbon, a mineral-associated organic carbon, microbial biomass carbon), total organic carbon, the carbon mineralization activities, and water retention capacities were observed to be highest in soils that were treated with (FM + M2, FM + M22, PM + M19, and MO + M19). Finally, we conclude that organics mineralization by microbial actions releases organic glues that not only impart particle aggregation but also conserve organics as aggregate entrapped carbon. Amalgamated application of microbe–manure combinations directly impacts soil structure and organic carbon contents, but in an indirect scenario, it improves the fertility and productivity of the soil. Therefore, it is strongly recommended to use organic manures and microbes in combination to restore structurally degraded lands.

“…The use of organic manure helps to prevent water loss by evaporation, the removal of the soil surface, and the seeping of nutrients out of the rhizosphere (Shahzad et al, 2020). The use of organic manure helps preserve soil fertility since it improves the soil's physical health and, due to its gradual mineralization process, provides nutrients at the optimal moment when they are needed (Shahzad et al, 2021). Because they contain less than 1% organic matter, the soils of Pakistan are considered to be poor in organic matter (Fatima et al, 2021).…”

The properties of the soil, both physical and chemical, have a considerable impact on the development and production of the crops. The soil texture, an unchanging soil physical property that affects the soil, has a secondary effect on crop growth. The goal of this study is to determine how different textures and organic amendments affect the root development of maize, which in turn affects the plant's ability to grow. In 2019 a pot experiment was conducted at Arid Zone Research Center in DI Khan, Pakistan, using two native soil types, clay loam and sandy loam. Farm manure was added as an amendment to the trial at rates of 0 (T0), 5 (T1), 10 (T2), and 15 (T3) Mg ha-1. Half the recommended NPK dose of 150:90:60 kg ha-1 was added to each treatment pot. The plant parameters including shoot length (89.6 cm), fresh weight (176.42 g), and dry weight (16.89 g), as well as root length (39.1 cm), fresh weight (37.11 g), dry weight (11.01 g) and 100-grain weight (22.23 g). The organic amendment added at a rate of 10 Mg ha-1 (T2) under sandy loam texture produced noticeably higher values. It was concluded that every plant parameter increased as the quantity of organic matter increased in the soil, however as the quantity of added organic matter reached 10 Mg ha-1, a significant drop was noticed. Additionally, it was discovered that crops performed well in sandy loam than in clay loam soil
