1. 1. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Rasha Kamel; [2023]
   Keywords : Apple Waste; Wood Chips; Microbial Content; pH; Pseudomonas; General Bacterial Flora; General Fungal Flora; Electrical Conductivity; Nutrient Content; Bulk Density; Porosity; Water Holding Capacity;

   Abstract : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. READ MORE

3. 2. Ammonium and nitrate sorption by biochar

   University essay from SLU/Dept. of Soil and Environment

   Author : Yasser Alrhban; [2023]
   Keywords : biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

   Abstract : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

4. 3. The potential for large-scale implementation of biochar in the agricultural sector : a quantitative study on plant growth in light soils and a qualitative study on the agricultural sector’s perception on biochar

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Mathilda Håkansson; Louise Strömberg; [2022]
   Keywords : Transdisciplinary study; Agricultural science; Biochar; Plant growth; Soil properties; Biochar implementation; Perceptions on biochar;

   Abstract : Agricultural activities are collectively one of the largest contributors to accumulation of greenhouse gasses (GHG). At the same time, agriculture is at a risk to be affected extensively by climate change. Concurrently, in conventional agriculture GHG emissions have become inevitable to maintain efficiency.

5. 4. Blågröngrå system i kallt klimat

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Jennika Jädernäs; Erika Tjernberg; [2021]
   Keywords : Blågröngrå system; dagvattenhantering; regnbädd; skelettjord; kallt klimat; grön urban infrastruktur; klimatanpassning; ekosystemtjänster; gatugestaltning; landskapsarkitektur;

   Abstract : Det finns stora möjligheter och behov att kombinera urbaniseringens markanspråk med grön urban infrastruktur och i det arbetet säkra en hållbar dagvattenhantering. Att som landskapsarkitekt arbeta med detta är viktigt eftersom markanspråken ökar mängden hårdgjorda ytor i städer vilket samtidigt reducerar grön urban infrastruktur. READ MORE

6. 5. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Lotte Wendt; [2021]
   Keywords : active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

   Abstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.
