1. Biowastes for Plant Production : a guide to plant biostimulants
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : Biostimulants are a suggested tool to achieve sustainable plant production. These are products sourced from biological processes or extracted from biological material, which induces physiological responses in plants. READ MORE

2. Nitrogen and phosphorus analysis in field cultivation of Pak choi : effect of two different compositions of fertilisers on plant and soil nutrient status
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : This pilot study was implemented to reflect the delivery and the plant availability of nitrogen and phosphorus in response to different compositions of fertilisers approved for organic farming in Sweden. The experimental approach was to compare the concentration of nitrogen and phosphorus in plant sap of Pak choi plants grown in soil treated with different organic waste such as aged cattle manure and a liquid retting digest derived from the biogas industry, with plants grown in soil treated with a blend of pelleted organic fertilisers derived from the Swedish slaughterhouse industry.

3. Nutrient dynamics in pak choi cultivation fertilized with biogas digestate : effects of non-nutrient digestate elements and amendment with mineral nutrients
University essay from SLU/Department of Biosystems and Technology (from 130101)Abstract : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. READ MORE

4. The effect of spent mushroom (Agaricus bisporus) compost on the indigenous rhizosphere microbiota in strawberry cultivation
University essay from SLU/Dept. of Agricultural Biosystems and TechologyAbstract : Spent mushroom compost (SMC) is a by-product of mushroom cultivation with the potential to be used in the cultivation system to suppress plant pathogens, enhance water holding capacity, increase soil water aeration and to improve the soil structure through the input of organic matter and additional nutrients. The electric conductivity (EC) as well as pH recorded high values in the SMC, which is a challenge for its application in food production systems. READ MORE

5. Effects of different biochar application rates on soil fertility and soil water retention in on-farm experiments on smallholder farms in Kenya
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Biochar is produced through pyrolysis, the thermo-chemical degradation of biomass under anaerobic or oxygen-limited conditions. Due to its properties related to surface area and porosity, bulk density, nutrient content, stability, cation exchange capacity (CEC), pH value, and carbon content, biochar has the potential to improve physical as well as chemical soil properties and thus improve crop productivity and contribute to carbon sequestration.
