Cation exchange capacity of biochar: An urgent method modification
Munera-Echeverri, Jose L; Martinsen, Vegard; Strand, Line Tau; Zivanovic, Valentina; Cornelissen, Gerard; Mulder, Jan (Peer reviewed; Journal article, 2018)Biochar, produced through pyrolysis of organic matter, is negatively charged, thus contributing to electrostatic adsorption of cations. However, due to its porous structure and contents of alkaline ashes, the determination ... -
Effect of biochar on crust formation, penetration resistance and hydraulic properties of two coarse-textured tropical soils
Obia, Alfred; Børresen, Trond; Martinsen, Vegard; Cornelissen, Gerard; Mulder, Jan (Peer reviewed; Journal article, 2017)Biochar (BC) has been reported to improve a number of soil structural and hydraulic properties but detailed studies are scant on how BC affects crust formation, penetration resistance, water repellency and saturated hydraulic ... -
Effect of conservation farming and biochar addition on soil organic carbon quality, nitrogen mineralization, and crop productivity in a light textured Acrisol in the sub-humid tropics
Munera-Echeverri, Jose L; Martinsen, Vegard; Strand, Line Tau; Cornelissen, Gerard; Mulder, Jan (Peer reviewed; Journal article, 2020)Conservation farming (CF), involving basin tillage, residue retention and crop rotation, combined with biochar may help to mitigate negative impacts of conventional agriculture. In this study, the effects of CF on the ... -
Effect of Soil pH Increase by Biochar on NO, N2O and N2 Production during Denitrification in Acid Soils
Obia, Alfred; Cornelissen, Gerard; Mulder, Jan; Dörsch, Peter (Journal article, 2015) -
Effect of Soil pH Increase by Biochar on NO, N2O and N2 Production during Denitrification in Acid Soils

Fading positive effect of biochar on crop yield and soil acidity during five growth seasons in an Indonesian Ultisol
Cornelissen, Gerard; Jubaedah, X; Nurida, Neneng; Hale, Sarah; Martinsen, Vegard; Silvani, Ludovica; Mulder, Jan (Peer reviewed; Journal article, 2018)Low fertility limits crop production on acidic soils dominating much of the humid tropics. Biochar may be used as a soil enhancer, but little consensus exists on its effect on crop yield. Here we use a controlled, replicated ... -
Multi-year double cropping biochar field trials in Nepal: Finding the optimal biochar dose through agronomic trials and cost-benefit analysis
Pandit, Naba Raj; Mulder, Jan; Hale, Sarah; Zimmermann, Andrew R.; Pandit, Bishnu Hari; Cornelissen, Gerard (Peer reviewed; Journal article, 2018)Poor water and nutrient retention are the major soil fertility limitations in the low productivity agricultural soils of Nepal. The addition of biochar to these soils is one way these hindrances can be overcome. In the ... -
Nutrient effect of various composting methods with and without biochar on soil fertility and maize growth
Pandit, Naba Raj; Schmidt, Hans Peter; Mulder, Jan; Hale, Sarah; Husson, Olivier; Cornelissen, Gerard (Journal article; Peer reviewed, 2019)This work showed for the first time that organic nutrient transformation techniques based on locally available materials (manure, green waste and advanced biochar) can increase fertilizing efficiency of the resulting ... -
