Abstract The physical properties of biochar have been shown to dramatically influence its performance as a soil amendment. This study assessed the role particle size and hydrophobicity in controlling water movement retention. Softwood pellet five ranges (>2 mm, 2–0.5 0.5–0.25 0.25–0.063 mm <0.063 mm) was used for experiment. These sizes were tested on two types (sandy loam loamy sand) at four different application rates (1, 2, 4 8%) laboratory. Soil suction wet range dry measured using...
Addressing soil nutrient degradation and global warming requires novel solutions. Enhanced weathering using crushed basalt rock is a promising dual-action strategy that can enhance health sequester carbon dioxide. This study examines the short-term effects of amendment on spring oat ( Avena sativa L .) during 2022 growing season in NE England. The experimental design consisted four blocks with control basalt-amended plots, two cultivation types within each treatment, laid out split plot...
Biochar is an engineered carbon-rich substance used for soil improvement, environmental management, and other diverse applications. To date, the understanding of how biomass affects biochar microstructure has been limited due to complexity analysis involved in tracing changes physical structure as it undergoes thermochemical conversion. In this study, we synchrotron x-ray micro-tomography visualize internal from feedstock (miscanthus straw pellets, wheat oilseed rape rice husk) during...

Abstract Fluted pumpkin ( Telfairia occidentalis ) has high agronomic and food relevance in the tropics. Production of this vegetable dry season with irrigation is increasingly popular mostly on droughty soils, thus requiring research appropriate combination soil moisture conservation/management practices. This study evaluated interactions among seedbed configuration (flat raised), surface mulching (grass‐mulched no‐mulch) plant spacing (100 2 , 50 25 cm designated wide, intermediate close...
There are insufficient data supporting the enormous potential of biochar in highly weathered tropical soils. This glasshouse study assessed rice-husk (RHB) effects on soil organic carbon, aggregate stability and nitrogen fertility sandy-loam Ultisols which were evaluated using spinach (<em>Celosia argentea</em>) growth. Five RHB rates 0, 5, 10, 20, 40 g per two-kg-soil (0, 7.5, 15, 30 60 t ha<sup>−1</sup>, respectively) studied under 4, 8, 12 weeks incubation (WOI)....
Organic inputs to tillage-pulverised soils could, by facilitating soil structure reformation with time, enhance environmental quality. This study examined the aggregate stability responses of three texture-contrasting from derived savannah southeastern Nigeria poultry-droppings (PD) manure over time. The Nsukka, Ukehe and Adani clay contents 53, 100 260 g/kg had antecent organic matter concentrations 18.77, 29.73 16.23 g/kg, respectively, sandy Nsukka/Ukehe being more stable than loamy...
Basalt Enhanced Weathering as a Carbon Dioxide Removal (CDR) technology accelerates natural weathering, enhancing the CO2 removal from atmosphere. The main objective of ongoing field trials in Scotland and UK is to combine geochemistry modelling with in-field measurement most accurately quantify sequestration. To measure weathering signal field, we track changes indicators such soil inorganic carbon (SIC), organic (SOC), exchangeable cations, trace/immobile elements, biomass. Pore water...
In tropical and subtropical areas, the importance of organic manure in improving soil physicochemical properties crop production for food security cannot be overemphasized.A study was conducted during 2012/2013 years to investigate effects rumen digesta on physical chemical soils Nsukka, Enugu state Nigeria.The samples collected from Opi, Nsukka were treated four rates (viz.0, 50, 100, 150 gkg -soils).Physical determined pre post-experiment.The results obtained revealed that significantly (p...
The study investigated variability of rheological and physical properties wormcast (Wc) termite mound (Tm) soils in relation to surrounding (Ss) Nsukka tropical subtropical areas. Rheological properties, shear strength compaction at different moisture contents were obtained. Relationships between other attributes established. Consistency limits Wc Tm significant. Mean (cohesion) high. was 85.09 kpa 91.55 for soils), while Ss had 69.80 kpa. maximum compacted (15 blows) 188 190 12 (db)...

&lt;p&gt;The physical properties of biochar have been shown to dramatically influence its performance as a soil amendment. Biochar particle size is one key parameters, it controls specific surface area, shape, and pore distribution. Therefore, this study assessed the role hydrophobicity in controlling water movement retention. Softwood pellet five ranges (&gt;2 mm, 2 &amp;#8211; 0.5 0.25 0.063mm &lt;0.063 mm) was used for experiment. These sizes were tested on types...
Enhanced weathering of silicate rock is a promising natural carbon dioxide removal technology, both due to its scalability and associated agronomical benefits. During weathering, dissolved in the form carbonic acid, reacts with minerals stable soil pore water bicarbonate or calcium carbonate. The potential enhanced has been successfully demonstrated short-term lab mesocosm studies. Due transient nature aqueous solution, in-field quantification sequestered tedious, labour-intense poorly...
This analysis compared the suitability of contiguous fallow-forest lands for cassava, yam, cocoyam and sweet potato production in Nsukka, south-eastern Nigeria. The fallow plots were brought into cultivation 1998 under IITA-UNN long-term collaborative research. sole cassava grown to only continuously five years then left fallow. Soil samples collected from 0-20 cm depth triplicates using an auger core sampler seven representative previously 1998–2003 till date as well adjacent forest land....
