Assessing the effectiveness of digestate enriched biochar as an alternative fertilizer
Fallas Yamashita, Vladimir Kazuomi (Master thesis, 2021)Background: Alternatives to conventional inorganic fertilizers are needed if we are to curve CO2 emissions, reduce the stress on natural resources and develop an efficient, yet sustainable agricultural practice. Biochar ... -
Effect of grazing in Norwegian outfields related to the quantity and quality of soil organic carbon and other soil properties
Ellingsen, Tonje Forsethlund (Master thesis, 2022)Utilization of the outfield for grazing have long traditions in Norway. Not only as a pasture, but also mowed to provide food for the winter (Rekdal & Angeloff, 2021). From 1949 to 1999, grazing in Norway changed from ... -
Effects of biochar and crop rotation with pigeon pea on soil phosphorus availability in Mkushi and Kaom, Zambia
Hovden, Ingrid Slettemark (Master thesis, 2022)Low phosphorus (P) availability in sub-Sahara African agriculture strongly effects yield and food production negatively. As fertilizer prices increases, the need for human interventions to increase soil plant available P ... -

The fate of nitrogen in an Acrisol in Zambia under different management practices
Talmo, Ina Kristine (Master thesis, 2019)A 10-day 15N tracer experiment, using 15N-NO3 and 15N-NH4, was conducted on an Acrisol in Mkushi, Zambia, in a rain-fed maize field. The addition of the 15N label, as either 15N-NO3 or 15N-NH4, was equivalent to 0.1g/m2 ... -
The impact of planting basins under conservation farming with and without biochar on aggregate stability, soil organic carbon, and pH in Zambian Acrisols
Ellingsen, Elisabeth Time (Master thesis, 2018)Conservation Farming (CF) in Sub-Saharan Africa (SSA), including reduced tillage, return of crop residue, and crop rotation, has been found to increase maize yields in rain-fed agriculture. In combination with the application ...
