    Abstract Application of biochar to agricultural soils is mostly used to improve soil fertility. Experimental treatments were comprised of two factors: i) drought at two level, i.e., 80% and 40% water holding capacity (WHC) which was maintained on gravimetric basis ii) three levels of biochar i.e., control, 2 t ha-1 and 4 t ha-1 added to soil. Experimentation was done to examine potential of biochar application to enhance the growth attributes, water relations, photosynthetic pigments and antioxidants activities in maize (Zea mays L.) seedlings. Results of study revealed that biochar application increased the growth qualities (total seedlings biomass,… More >

    Biochar Production and Application in Forest Soils-A Critical Review

    Lina Gogoi1, Rumi Narzari1, Nirmali Gogoi2, Muhammad Farooq3, Rupam Kataki1,*

    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 349-365, 2019, DOI:10.32604/phyton.2019.08406

    Abstract The increasing deforestation with an alarming rate is the prime cause of upsetting the balance in the natural ecosystem and the livelihood of local communities. Sustainable forest management and reforestation efforts can equilibrium this destruction and maintain the protected areas. In this regard, soil management strategies for reforestation of the degraded forest land can be helpful. In this review, the potential of using biochar, a solid carbon rich product of biomass thermochemical conversion, as a soil amendment in forest soils has been discussed. The production procedures of biochar, availability of feedstocks and the biochar properties More >

    Biochar Effectively Reduces Ammonia Volatilization From Nitrogen-Applied Soils in Tea and Bamboo Plantations

    Lei Chu, H. M. K. Darshika Hennayake, Haijun Sun*

    Phyton-International Journal of Experimental Botany, Vol.88, No.3, pp. 261-267, 2019, DOI:10.32604/phyton.2019.07791

    Abstract Intensive practices in forest soils result in dramatic nitrogen (N) losses, particularly ammonia (NH3) volatilization, to adjacent environmental areas. A soil column experiment was conducted to evaluate the effect of bamboo biochar on NH3 volatilization from tea garden and bamboo forest soils. The results showed that biochar amendment effectively reduced NH3 volatilization from tea garden and bamboo forest soil by 79.2% and 75.5%, respectively. The soil pH values increased by 0.53-0.61 units after biochar application. The NH4+-N and total N of both soils were 13.8-29.7% and 34.0-41.9% higher under the biochar treatments than under the control treatment, More >
