Nano-silicon and nano-calcium enriched biochars mitigated salt stress in safflower by enhancing ion homeostasis and root growth

Biochar and nanoparticle composites (nano-modified biochar) as next-generation soil amendments for sustainable salt stress management.

BACKGROUND Soil salinity is one of the most critical abiotic stressors limiting global agricultural productivity by adversely affecting plant physiology, nutrient dynamics and soil health. Excessive accumulation of soluble salts disrupts osmotic balance, induces ionic toxicity and elevates oxidative stress, thereby imp...

Nano-Iron Alleviates Carbohydrate Deficiency and Improves Yield of Soybean Under Saline-Alkali Stress by Regulating Photosynthetic Carbon Assimilation.

In salinized soils, high salt and pH inhibit iron availability via chelation and ion competition, inducing iron deficiency stress in plants. Compared with traditional iron fertilizers, nano-iron has characteristics like easy absorption and targeted slow release, showing great potential in improving plants' saline-alkal...

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.

Biochar and nitrogen effects on nitrate leaching, physiological performance, and rhizome quality of turmeric (Curcuma longa L.) in sandy soil

Nitrogen fertilization in sandy soils often results reducing nitrogen use efficiency and posing environmental risks. Biochar has been proposed as a soil amendment to improve nutrient retention and crop quality. However, the combined effect of biochar and graded nitrogen rates on the physiology and rhizome quality...
