1. 1. Dissolution rates of mineral nitrogen fertilisers : effects of moisture and precipitation

   University essay from SLU/Dept. of Soil and Environment

   Author : Christian Sigtryggsson; [2018]
   Keywords : hygroscopicity; deliquescence; fertilisers; calcium nitrate; ammonium nitrate; dissolution rates; rain simulation; enthalpy; precision fertilisation;

   Abstract : Hygroscopicity and deliquescence refer to the ability of a solid to absorb air moisture in which it dissolves and have long been recognised as properties having negative impacts on the product quality of explosives, pharmaceuticals, and fertilisers. Contrastingly, this thesis reconsiders and reappraises the hygroscopic effects of common mineral fertilisers, proposing hygroscopicity to beneficially enable quick dissolution under humid air conditions in absence of precipitation.

3. 2. Simulations of drainage and phosphorus leaching with the ICECREAM model for 15 years at Mellby experimental field

   University essay from SLU/Dept. of Soil and Environment

   Author : Jian Liu; [2010]
   Keywords : drainage; phosphorus leaching; ; ICECREAM model; Mellby experimental field;

   Abstract : Phosphorus (P) losses from agricultural fields have been recognised as one of the mostimportant sources of P causing eutrophication in water bodies. Water transport in soil playsan important role in P leaching from drained fields. READ MORE
