Journal ArticleDOI
Pyrolysis temperature induced changes in characteristics and chemical composition of biochar produced from conocarpus wastes.
TL;DR: Results suggest that biochar pyrolized at high temperature may possess a higher carbon sequestration potential when applied to the soil compared to that obtained at low temperature.
Journal ArticleDOI
Biochar composition-dependent impacts on soil nutrient release, carbon mineralization, and potential environmental risk: A review.
Ali El-Naggar,Ahmed H. El-Naggar,Sabry M. Shaheen,Binoy Sarkar,Scott X. Chang,Daniel C.W. Tsang,Jörg Rinklebe,Yong Sik Ok +7 more
TL;DR: The linkage between biochar composition and function is discussed, the role biochar plays in soil fertility improvement and C sequestration is evaluated, and regulations and concerns regarding biochar's negative environmental impact are discussed.
Journal ArticleDOI
Conocarpus biochar as a soil amendment for reducing heavy metal availability and uptake by maize plants.
Mohammad I. Al-Wabel,Adel R.A. Usman,Ahmed H. El-Naggar,Anwar A. Aly,Hesham M. Ibrahim,S.E. El-Maghraby,Abdulrasoul Al-Omran +6 more
TL;DR: The results suggest that biochar may be effectively used as a soil amendment for heavy metal immobilization and in reducing its phytotoxicity.
Journal ArticleDOI
Conocarpus Biochar Induces Changes in Soil Nutrient Availability and Tomato Growth Under Saline Irrigation
Adel R.A. Usman,Adel R.A. Usman,Mohammad I. Al-Wabel,Yong S. Ok,A. R. Al-Harbi,M. A. Wahb-Allah,M. A. Wahb-Allah,Ahmed H. El-Naggar,Ahmed H. El-Naggar,Mahtab Ahmad,Abdulelah Al-Faraj,Abdulrasoul Al-Omran +11 more
TL;DR: In this paper, the authors investigated the effects of Conocarpus biochar (BC) and organic farm residues (FR) at different application rates of 0.0%, 4.0% and 8.0%.
Journal ArticleDOI
Carbon mineralization and nutrient availability in calcareous sandy soils amended with woody waste biochar
Ahmed H. El-Naggar,Adel R.A. Usman,Abdulrasoul Al-Omran,Yong Sik Ok,Mahtab Ahmad,Mohammad I. Al-Wabel +5 more
TL;DR: The incorporation of biochar into calcareous soils might have benefits in carbon sequestration and soil fertility improvement and the combined addition of PM+BC increased available N, P and K compared with the PM or BC treatments.
