1. 1. Quantifying relationships between X-ray imaged macropore structure and hydraulic conductivity

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Muhammad Arslan Ahmad; [2016]
   Nyckelord :critical pore diameter; modelling; pedotransfer functions; physics based approaches; SoilJ; 3-D visualization; soil characterization;

   Sammanfattning : Computer based simulation models which estimate hydraulic properties of soil usually make use of statistical approaches such as multiple regressions that relate hydraulic properties to widely measured soil properties like textural fractions, organic matter content and bulk density. The problem is that hydraulic properties are usually only weakly correlated to these properties, because it is more strongly dependent on the characteristics of larger pores in the soil. LÄS MER

3. 2. Evaluation of organic residues and their mixtures with Peepoos to produce fertilizer.

   Master-uppsats, KTH/Mark- och vattenteknik

   Författare :Arslan Ahmad; [2014]
   Nyckelord :C-N ratio; Dry matter; Organic residues; pH; Peepoos; Sanitation;

   Sammanfattning : Peepoo, self-sanitising, biodegradable toilet is characterized by low carbon to nitrogen (C-N) ratio and low dry matter (DM) content. Principal nutrients (nitrogen (N), phosphorous (P) and potassium (K)) are also not in a balance as required by most crops. LÄS MER
