Coal fly ash (CFA) is a byproduct using coal as an energy source in power plants. The long-term storage of this industrial waste in open, indiscriminate disposal sites without further consumption poses environmental issues. Khan and Umar (2019) showed an increase in the concentration of several heavy metals in groundwater near CFA disposal sites, which exceeded the World Health Organisation’s (Dowhower et al. 2020) recommended drinking water standards. Several studies have also shown toxic contamination elements in soil and groundwater around the disposal sites (Kicińska 2019, Seki et al. 2021). The aforementioned results show the need for CFA management to prevent soil and groundwater exposure to toxic elements originating from leached CFA. The mineral and chemical properties of CFA allow the reuse of CFA to have a better economic value while simultaneously reducing environmental risks.

: Soil macroarthropods, as a component of the soil community, directly feel the impact of land use chan-ges. Not only the density but understanding the soil macroarthropods distribution pattern will help in providing an insight into the quality of soil health. The sampling process was carried out using the pitfall trap methods on the forest, logged forest areas, mixed gardens, and monoculture gardens in the tropical rainforest of Bukit Pinang-Pinang Padang, Indonesia. The results showed that the forest as a natural habitat supported the density of soil macroar-thropods among other land use types. The density in the forest, logged forest area, mixed garden, and monoculture garden sequentially is about 20.29, 13.18, 15.2 and 12.21 indv/m 2 . The presence frequency high value of soil macroar-thropods was found in the forest, and for some soil macroarthropods, such as Hymenoptera, Diptera, and Araneits, the importance value increases when their habitat is disturbed. The fertile soil in intensive monoculture gardens does not support the individuals’ total number, types, and density of soil macroarthropods. On the other side, the dominant soil macroarthropods prefer disturbed soil conditions and will decrease their presence frequency if chemical compounds are introduced into the soil. Land use change in the Bukit Pinang-Pinang tropical rainforest area causes changes in the distribution pattern of soil macroarthropods. The changing tendency of distribution patterns in fragmented habitats is due to nutrient availability, limited resources and land treatment. Habitat fragmentation affects not only the abundance and density of individuals and types of soil macroarthropods but also the distribution pattern, which not only threatens their existence and the environment but also has the potential to regenerate.

: The effect of drought stress on carbon metabolism in the leaves and roots of bermudagrass was investigated. Plants established in PVC tubes suffered from three water treatments for 10 days. C138 and Tifway (drought-tolerant) were found to have lower relative electrical conductivity and higher water use efficiency than C32 (drought-sensitive) under moderate drought by increasing carotenoid and soluble sugar content and rapidly decreasing leaf starch content. The sucrose synthase activity of leaves and roots, acid invertase and neutral invertase activity of C32 roots substantially decreased under severe drought, resulting in a slow sucrose decomposition rate and significantly lower fructose and glucose contents than C138 and Tifway. The activities of four carbon metabolism enzymes and sucrose content in the leaves were greater than those in the roots, while the fructose and glucose contents were on the contrary, indicating that bermudagrass transported fructose and glucose obtained from sucrose decomposition from leaves to roots under drought to reduce roots damage. The path analysis indicated that leaves neutral invertase activity, and roots soluble sugar content might be the key parameter of carbon metabolism in bermudagrass under drought.

Soil health in terms of plant available nutrients is crucial to estimate the yield potential of agricultural land in an area. Based on the availability of soil health data, it is possible to set yield targets using various yield prediction models. This study was initiated to estimate the concentration of DTPA-extractable micronutrients in Tehsil Muzaffargarh and to develop a database that can be used to develop predictive models. Soil samples (n=11537) were collected from Muzaffargarh (0-15 cm depth). The latitude and longitude values of sampling points were recorded for the purpose of georeferencing the soil samples. Micronutrients such as zinc (Zn), copper (Cu), iron (Fe) and manganese (Mn) were extracted with diethylenetriamine penta-acetate (DTPA) extraction solution and their concentrations were determined with atomic absorption spectrophotometer. Water soluble boron (B) was determined spectrophotometrically using Azomethine-H as colour developing reagent. Critical limits established by the National Agricultural Research Center (NARC) Islamabad, Pakistan, were used as a benchmark for grading micronutrient status. The ordinary kriging technique was used to visualize the micronutrient status in the surveyed area and digital maps were prepared using Quantum Geographic Information System (QGIS) software. Results showed that the range of DTPA-extractable micronutrients Zn, Fe, Mn, and Cu ranged from 0.10-5.92, 0.01-12.51, 0.09-10.00 and 0.03-8.08 µg/g, respectively. Boron concentration ranged from 0.02-1.98µg/g. Most of the soils in the studied area had adequate levels of Zn (61.9%) and Cu (48.6%) while 45.8, 43.3 and 55.4 % of the soil samples fell into the marginal category in terms of Cu, Mn, and B, respectively. The results revealed the widespread deficiency of DTPA-extractable Fe (< 4.5mg kg-1 in 74% soil samples) in Tehsil Muzaffargarh. The digitized maps developed from this study would serve as primary source to locate micronutrient deficient areas and also set site-specific yield targets along with other biophysical factors. However, these maps need ground truthing after crop harvest each year.

Nitrogen is an essential element, which can come from mineralization of organic N in plant residues. The measurement of nitrogen mineralization is important for estimating nitrogen availability and determining fertilizer requirements. This study aims to evaluate N mineralization of straw and cow manure in organic paddy fields at different water conditions through laboratory incubation. Types of paddy field management (organic, semi-organic, and conventional), organic matter (straw and cow manure), and moisture conditions (aerobic and anaerobic) were used in these research. The NH4+ and NO3ˉ concentration, soil pH, and water content were measured eight times over 56 days of incubation. Microbial biomass was measured at the end of the incubation. The data were analyzed using three-way ANOVA followed by the DMR and Pearson correlation test. Results showed that the application of cow manure on organic paddy fields in anaerobic conditions increased NH4+ up to 18.56 mg kg-1 and increased NO3ˉ in aerobic conditions up to 7.71 mg kg-1 from the initial concentration. Organic paddy fields with cow manure input under anaerobic conditions have the highest N mineralization potential. The N mineralization rate of straw and cow manure in organic paddy fields under anaerobic conditions was not significantly different. For 8-week incubation, adding straw in organic paddy fields increased NH4+ by 109% and NO3ˉ by 14%, whereas cow manure increased NH4+ by 128% and NO3ˉ by 18%. Application of plant residue or manure is an effective strategy to enhance soil microbial biomass and soil N availability and has the potential to reduce the dependence upon chemical N fertilization.

Regular use of organophosphate pesticides (OPPs) such as chlorpyrolifos in agriculture results in a variety of environmental issues, including groundwater contamination, surface water pollution, enhanced floral and faunal resistance, soil acidity, reduced soil fertility, and nitrate leaching. The objective of the current study was to identify and isolate bacterial strains from native soil that could degrade chlorpyrifos and had high pesticide resistance. A total of 60 distinct microbial strains were isolated from the soil samples and subsequently evaluated for their capacity to degrade chlorpyrifos. Serratia liquefaciens, one of the strains, was discovered to be the most effective among them for degrading chlorpyrifos. It was subsequently examined for the biodegradation of chlorpyrifos under various environmental conditions and was then identified using 16S rRNA sequencing. The strain S. liquefaciens degraded more than 90% of 50 mg L-1 of chlorpyrifos. The strain performed better when urea and sucrose were used as nitrogen and carbon sources, respectively. At a temperature of 35 °C and a basic pH range, the strain functioned exceptionally well. The finding demonstrated that the bacterial strain S. liquefaciens, which was isolated from agricultural soil, is a top contender for cleaning up OPP-contaminated soil.

Edaphic factors, especially soil salinity, are a more significant challenge to food security irrespective of introducing technical innovations in agriculture. Saline-sodic soils continue to deteriorate the yield of a crop, causing a severe risk to worldwide food production. A field study was conducted in Vehari district, Pakistan, in already prevailing saline-sodic soils to evaluate tomato yield and quality by applying naphthyl acetic acid (NAA) and salicylic acid (SA) as their sole applications and in combination with organic fertilizers in saline-sodic conditions. NAA (@ 200mg L-1) and SA (@ 0.50 mM) were applied solely through a foliar spray. Additionally, NAA and SA were value-added in organic fertilizers. Maximum tomato growth and yield were noticed with combined NAA and SA application to organic fertilizer that can be seen in tomato quality parameters, like lycopene, beta carotene, ascorbic acid, titratable acidity, and total soluble solids. Conclusively, our research work offers an insightful practice of the value-addition of NAA or SA onto organic fertilizer that can enhance tomato productivity, and quality grown under saline-sodic soils.
