  4. 4. 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.
