“…Biochar acts as a good adsorbent for removing heavy metals, dyes, and several other pollutants from wastewater. Several studies have reported the ability of algal biochar as an adsorbent of heavy metals (HMs) to help with pollution reduction [141]. For example, Poo et al [112] prepared biochar from Saccharina japonica and Sargassum fusiforme to efficiently remove HMs from aqueous solutions.…”

“…The efficiency of biochar for removing pollutants was attributed to increasing the effective surface sorption sites and adding superficial functional groups for the enhancement of biochar sorption ability, improving its ability to adsorb heavy metals from soils [142]. It has been reported that biochar produced from waste marine algae has a higher efficiency than other feedstocks, such as pinewood sawdust, in removing heavy metals from polluted soils [141] (Table 4). The various functional groups and porous structures of algal biochars produced at moderate temperatures can absorb pollutants more than coal fuel produced at relatively lower temperatures.…”

The excessive use of agrochemicals to ensure food security under the conditions of a growing population, global climate change, weather extremes, droughts, wasteful use of freshwater resources, and land degradation has created severe challenges for sustainable crop production. Since the frequent and abrupt environmental changes are outcompeting the existing agricultural technologies of crop production systems to meet food security, the development and use of modern technologies and nature-based solutions are urgently needed. Nanotechnology has shown potential for revolutionizing agri-production and agri-business in terms of nanofertilizers and nanoparticles for crop protection. Furthermore, in the recent past, biochar has been identified as a negative emission technology for carbon sequestration and soil fertility improvement. However, supply chain issues for biochar, due to feedstock availability, challenges its worldwide use and acceptability. Meanwhile progress in algae research has indicated that, algae can be utilized for various agro-ecosystem services. Algae are considered an efficient biological species for producing biomass and phytochemicals because of their high photosynthetic efficiency and growth rate compared to terrestrial plants. In this context, various options for using algae as a nature-based solution have been investigated in this review; for instance, the possibilities of producing bulk algal biomass and algal-based biofertilizers and their role in nutrient availability and abiotic stress resistance in plants. The potential of algae for biochar production (hereafter “phycochar” because of algal feedstock), its elemental composition, and role in bioremediation is discussed. The potential role of agal nanoparticles’ in mitigating abiotic stress in crop plants was thoroughly investigated. This review has effectively investigated the existing literature and improved our understanding that, algae-based agro-solutions have huge potential for mitigating abiotic stresses and improving overall agricultural sustainability. However, a few challenges, such as microalgae production on a large scale and the green synthesis of nanoparticle methodologies, still need further mechanistic investigation.

“…In addition, along with the weathering process in the soil, poschar can slowly provide macro and micronutrients that can increase soil fertility and crop yields. The key factors that contribute to improving soil fertility when using biochar are the addition of organic carbon, the gradual release of nutrients from chelation effects, increasing the soil's water-holding capacity, and the increasing porosity [45]. The wide pores in this biochar improve drainage, aeration, and the soil's capacity to absorb ions and air.…”

Abundant animal manure in livestock areas has the potential to be used as organic fertilizer which can restore soil fertility by turning it into compost and biochar. The goal of this study was to as-sess how well soil fertility and red chili yield might be increased by using biochar and poschar made from various animal wastes. In this investigation, a factorial pattern and randomized block design were used. The first factor was the biochar treatment type, which included no biochar, biochar made from cow manure, biochar made from goat manure, and biochar made from chicken manure. The second factor was the type of poschar, which included no poschar, poschar made from cow manure, poschar made from goat manure, and poschar made from chicken manure. The findings of this study suggest that using biochar in conjunction with poschar can significantly improve soil parameters such as soil water content, pH, EC, humic acid, fulvic acid, C, N, P, K, and CEC. Red chilies grow and yield more per hectare when different types of biochar and poschar are used. The use of biochar from cow manure together with poschar from chicken manure shows the best agronomic effectiveness.
