The greatest challenge for the agriculture sector in twenty-first century is to increase agricultural production feed burgeoning global population while maintaining soil health and integrity of agroecosystem. Currently, application biochar widely implemented as an effective means boosting sustainable having a negligible influence on ecosystems environment. In comparison traditional biochar, nano-biochar (nano-BC) boasts enhanced specific surface area, adsorption capacity, mobility properties within soil, allowing it promote properties, crop growth, environmental remediation. Additionally, carbon sequestration reduction methane nitrous oxide emissions from can be achieved with nano-BC applications, contributing climate change mitigation. Nonetheless, due cost-effectiveness, sustainability, friendliness, waste-derived may emerge most viable alternative conventional waste management strategies, circular bioeconomy broader goal achieving Sustainable Development Goals (SDGs). However, it's important note that research still its nascent stages. Potential risks, including toxicity aquatic terrestrial environments, necessitate extensive field investigations.

Small particles, big effects: How nanoparticles can enhance plant growth in favorable and harsh conditions

Journal of Integrative Plant Biology, Journal Year: 2024, Volume and Issue: 66(7), P. 1274 - 1294

Published: April 5, 2024

ABSTRACT By 2050, the global population is projected to reach 9 billion, underscoring imperative for innovative solutions increase grain yield and enhance food security. Nanotechnology has emerged as a powerful tool, providing unique this challenge. Nanoparticles (NPs) can improve plant growth nutrition under normal conditions through their high surface‐to‐volume ratio physical chemical properties. Moreover, they be used monitor crop health status augment resilience against abiotic stresses (such salinity, drought, heavy metals, extreme temperatures) that endanger agriculture. Application of NPs stress tolerance mechanisms in plants, minimizing potential losses raise quality. This review highlights need comprehensive exploration environmental implications safety nanomaterials provides valuable guidelines researchers, policymakers, agricultural practitioners. With thoughtful stewardship, nanotechnology holds immense promise shaping environmentally sustainable agriculture amid escalating challenges.

Effect of silicon nanoparticle-based biochar on wheat growth, antioxidants and nutrients concentration under salinity stress

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: March 16, 2024

Globally, salinity is an important abiotic stress in agriculture. It induced oxidative and nutritional imbalance plants, resulting poor crop productivity. Applying silicon (Si) can improve the uptake of macronutrients. On other hand, using biochar as a soil amendment also decrease due to its high porosity, cation exchange capacity, water-holding capacity. That's why current experiment was conducted with novelty explore impact nanoparticle-based (Si-BC) on wheat cultivated salt-affected soil. There were 3 levels Si-BC, i.e., control (0), 1% Si-BC1, 2.5% Si-BC2 applied replicates under 0 200 mM NaCl following completely randomized design. Results showed that treatment performed significantly better for enhancement shoot root length, fresh weight, dry number leaves, tillers, spikelets, spike weight compared no (200 NaCl). A significant chlorophyll (~ 18%), b 22%), total 20%), carotenoid 60%), relative water contents 58%) signified effectiveness than NaCl. In conclusion, potentially mitigate by regulating antioxidants improving N, K concentration, gas attributes while decreasing Na Cl concentration electrolyte leakage. More investigations at field level are recommended declaration best alleviating different crops variable climatic conditions.
