From Salt‐Affected Marginal Land Resource to Remediation Agent: Halophyte‐Derived Biochar for Ameliorating Cd‐Contaminated Acidic Soil

Land Degradation &Development, EarlyView.
ABSTRACT Cadmium (Cd) contamination of acidic soils poses a significant threat to ecosystem stability and crop health. This study evaluated the potential of biochar derived from the halophyte Salicornia europaea (SBC), a salt‐tolerant plant that grows on saline‐alkali marginal land, to remediate Cd‐contaminated acidic soil.

Harnessing Spatial and Multi‐Criteria Decision Analysis (MCDA) to Optimize Land Suitability for Kenaf Cultivation in Kelantan: Pathways for Sustainable Economic Development

Land Degradation &Development, EarlyView.
ABSTRACT In Kelantan, entrenched land degradation and extensive idling of agricultural lands exacerbate rural poverty. Current top‐down planning often overlooks local geographic and social constraints, despite state initiatives to convert idle lands and strengthen rural livelihoods.

Effect of leaching with 5–6 N H2SO4 on thermal kinetics of rice husk during pure silica recovery

Journal of Advanced Research, 2016
Rice husk is a potential source for renewable energy and silica. To extract the maximum amount of silica, usually the rice husk is treated with strong acids that burn the organic part leaving behind a black residue.

Soil Humic Substances and Root Exudates: Key Factors Modulating Cadmium Mobility in Paddy Soils Under Organic Fertilization

Land Degradation &Development, EarlyView.
ABSTRACT Cadmium (Cd) contamination in paddy fields poses a high potential risk of environmental exposure. Organic fertilizer application can promote the efflux of rice root exudates, increase soil organic matter, and induce changes in Cd activity in rice fields.

Ditch‐Buried Straw Return Improves Soil Physical Quality and Crop Biomass in Two Rice–Wheat Paddy Soil Systems

Land Degradation &Development, EarlyView.
ABSTRACT Ditch‐buried straw return (DB) is an innovative practice combining deep tillage and straw incorporation. This study aimed to evaluate its effects on soil physical quality compared to rotary tillage (RT) and identified key constraints to crop in sandy‐loam and clay‐loam paddy soils within rice–wheat systems. Two field experiments were conducted

Performance evaluation and application framework for sustainable brick manufacturing using rice husk ash

Discover Civil Engineering
This study investigates rice husk ash as a partial replacement for clay in sustainable brick manufacturing. Seven brick compositions were developed with rice husk ash contents of 0%, 5%, 7%, 9%, 11%, 13%and 15% by weight.

Engineering Phosphorus‐Modified Flame‐Retardant Thermoplastic Polyurethane via Reactive Melt Processing

Journal of Polymer Science, EarlyView.
Phosphorus‐modified TPUs are prepared by one‐step, solvent‐free reactive melt processing using phosphate‐ or phosphonate‐containing diols and PEG or PPG soft segments. Fire behavior and mechanical response depend strongly on both chemistries. Peak heat release rate decreases by up to 54%, but reduced tensile strength and V‐2 dripping behavior reveal a ...

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Rice Husk Resource for Energy and Cementitious Products with Low CO2 Contributions

Nordic Concrete Research, 2018
Rice Husk Ash (RHA) is a well-known supplementary cementitious materials (SCMs) that can be used for concrete with reduced CO2 contributions. In 2016, only Nepal produced 5.2 million tonnes rice that gave about 1.14 million tonnes rice husk.

Fonio (Digitaria exilis and Digitaria iburua) in Nigeria: Regional cultivation patterns, landrace diversity, and farmer knowledge for conserving a climate‐resilient indigenous cereal

PLANTS, PEOPLE, PLANET, EarlyView.
Fonio (Digitaria exilis and Digitaria iburua) cereals are valued for their drought resilience, adaptability to poor soils, and cultural importance. In Nigeria, where both species are cultivated, fonio has declined due to labor‐intensive processing, lower yields, and changing livelihood choices. By documenting 21 landraces (15 D. exilis and 6 D. iburua),
