1. 1. Investigating organic fertilisers’ ability to mineralize during the first month of plant propagation

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

   Author : Sebastan Farkas; [2023]
   Keywords : organic fertilizers; sustainability; mineralisation; nitrification;

   Abstract : There are many forms of organc fertilizers produced and sold in the EU, and it can be difficult to assess which ones are the best in regards of nutrient content and the rate of mineraliztion. Two separate trials were conducted to assess the mineralization rates of three different organic fertilizers, available for private customers, on the Swedish market. READ MORE
