Biochar and hydrochar for saline soil amelioration and rice seedling growth promotion

Biochar-assisted reclamation of saline-sodic soil: Impact on soil properties, barley growth and yield

Soil salinity and sodicity are major problems negatively affecting soil properties, fertility, and crop production. In this study, the effect of biochar and phosphogypsum (PG) treatments on the reclamation of saline-sodic silt loam soil was examined. The biochar (BC) treatments included 0.5% (BC0.5), 1% (BC1), and 2% (...

Synergistic Effects of Humic Acid, Carboxymethyl Chitosan, and Calcium Alginate-Loaded Biochar on Saline Soil Improvement and Wheat Growth

Unraveling water-biochar synergy under cadmium stress: Coupled enhancement of photosynthetic physiology and bacterial community structure in maize seedlings.

This pot-scale study provides reliable experimental evidence for the synergistic effects of water and biochar on maize seedlings under Cd stress and suggests a mechanistic framework that warrants further validation under field conditions.

Potential of Composted Macrophytes as a Sustainable Organic Fertilizer: Environmental and Agronomic Insights

This study evaluated the agronomic potential and environmental impact of a macrophyte-based fertilizer (OMF) in maize cultivation. OMF was previously characterized in accordance with regulatory standards and applied to sandy loam and clayey soils at six rates (0, 2, 4, 6, 8, and 10 g dm⁻³). The experimental design also...

Effects of Modified Chicken Manure Biochar-Based Bacillus velezensis Agent on Vegetable Growth, Saline–Alkali Soil Properties, and Microbial Communities

Soil salinization limits sustainable agriculture. This study used a citric acid–FeSO4 method to create modified chicken manure biochar (MCMB) as a carrier for the plant growth-promoting Bacillus velezensis SS-20, forming a biochar-based microbial agent (JS). A pot experiment included four treatments: CK (control), SS (...

Synergistic Effects of Biochar and Nitrogen Fertilizer on Soil Humification and Japonica Grain Yield in Black Soil Paddy Systems of Northeast China
