Latvian lakes are rich in
sapropel sediments and below the sapropel layer there is
another valuable natural resource, namely blue clay. Flax shives are formed in large quantities as
a waste in flax processing factories.
The problem involves processing and rational use of these
reso
urces. The paper studies the obtaining of briquettes from flax shives using sapropel and lake
clay as a binding material. Briquettes are intended for use in cases when problems with regular
plant watering occur. For example, provision of plants with water
in greenhouses, indoor spaces
for a long period of time without human presence. Briquettes are placed into the soil next to the
plant roots. Briquettes are initially moistened and absorb a significant amount of water (moisture
content to be expressed in co
mparison to the sample's dry weight 250
–
380%). The presence of
clay in them contributes to slow drying of briquettes and provides a long lasting supply of
moisture to the plant roots. The paper deals with the issues of the optimal composition of
components
and the amount of pressure for the production of briquettes, as well as water
absorption and desorption properties of briquettes. The aim of the study is to develop a production
method of clay

sapropel
–
flax shive briquettes with good water absorption
and desorption
properties.
