Thematic training material for the use of liquid manure as fertilizer has been published

May 28, 2021

Livestock manure from housing usually contains high percentage of water which consist of urine, spilt feed and drinking water as well as water for washing. During physical separation, most of water retains in the liquid fraction, together with the soluble nutrients including mineral N, orthophosphate, K, etc. This liquid manure can be used as a liquid organic fertiliser in agriculture. With post-treatments such as evaporation and membrane filtration, the nutrients in liquid manure can be concentrated and the volume can be reduced which saves the transportation cost. Additionally, acidification is used to reduce the GHG emission from liquid manure during storage, transportation and application. Normally liquid manure is injected or incorporated immediately into soil to reduce emissions. Due to the relatively low P and high mineral N&K, liquid manure has the priority to be used in regions rich in P or have restrictions on P application.
