5.6 Using the air outlet valve
• normally, the air outlet air valve (part 8) does not need to be
adjusted. It is open, and cannot be closed at all. If the mois-
ture-content of the composter is high, you can increase the
ventilation by opening the valve.
• to open the valve, move its knob to the right to the position
"extra", i.e. to the right, as seen from behind the composter.
• when using the composter in winter, observe that the in-
creased ventilation may cool down the composter. Keep an
eye on how the situation develops.

6. USING THE COMPOST AND THE SEEP
ET
LIQUID IN THE GARDEN
The compost makes an excellent soil conditioner as it contains
LT
nutrients with a long-lasting effect that are usable for the plants.
Compost soil changes and develops constantly, and during dif-
ferent stages of its development, It should be used in a differ-
ent manner. Compost soil is typically divided into two categories
LV
based on its maturity: half-mature cover soil and mature com-
post soil.
Maturing cover soil to compost soil
NO
The mass, emptied from the Biolan Composter, has usually ma-
tured to the cover soil stage. It is recommended that cover soil is
only used under ornamental plants. If you wish to use it for edible
PL
plants, post-compost it for another year to allow it to develop
into proper compost soil.
Using cover soil
FR
By cover soil we understand the semi-mature compost mass.
At this stage, the decomposing has advanced to such an extent
that all the food waste has already decomposed. Harder wood
matter and, for example, eggshells and citrus fruit peels may not
CS
yet have completely decomposed; thus the cover soil has a rough
look. The half-mature compost soil may still contain substances
that hamper germination and growth. For this reason, there is no
DA
point in using it as substrate. The cover soil is not harmful to the
plants, if it is applied under ornamental plants as a few centime-
tres thick layer. Then the nutrients, which the compost contains,
will be released for the disposal of the plants.
6.1 Using mature compost soil
The fertilising effect of the compost depends on its raw ma-
terials. Compost created from domestic waste has in general
a better nutritive value than compost based on garden waste.
Plain compost soil as such does not make a good substrate, so it
should be mixed with at least 1/3–1/2 of mineral soil, such as, for
example, sand, silt, loam or clay.

6.2 Using seep liquid
If you have collected the excess seep liquid separated from the
bottom of the composter via a hose connected to the seep liquid
hole in the composter, you can utilise it. The seep liquid contains
nutrients that the plants can make use of.
• before watering garden plants, the seep liquid should be di-
luted in a ratio of at least 1:2.
• you can also recycle the seep liquid by pouring it from above
into the mass in the Composter Biolan 220
and absorb in it at most 5 litres of liquid per day. If the mass is
already wet, do not water it any further with seep liquid.
7. PROBLEMS THAT MAY OCCUR
Is the composting not successful?
Most of the problems result from using the wrong
bedding or using it too sparsely.
What is the correct temperature of the
compost?
In the Composter Biolan 220
the composting mass varies between +10 – +70 °C.
Typically, the reading of the temperature gauge is
+30 - +40 °C. The most important factor for keeping
the composting process alive is that the mass does
not freeze.
7.1 Smell of decay
If the composter smells rotten, the mass is too tightly packed
and wet, and has run out of oxygen.
• check that the bedding used Biolan bulking material.
• check that you have added a sufficient amount of Biolan
bulking material
• increase the amount of bedding temporarily to bring the mois-
ture-content under control.
• open and empty the biodegradable bags before putting them
into the composter.
• open the outlet air valve (part 8) on the cover more (see point
5.6).
• empty wet mass the lower way out of the composter (see
point 5.2). Spread it in a layer a couple of centimetres thick
under ornamental plants. The unpleasant smell will disappear
in a few days.
• add a couple of spadefuls of Biolan bulking material through
the emptying door (part 15) onto the bottom of the composter.
• drop the mass from above and mix it with a large amount of
Biolan bulking material.
7.2 Smell of ammonia
A pungent smell of ammonia from the composter means that
nitrogen is evaporating from the mass. If the nitrogen content
compared with the carbon content is too high, the micro-organ-
isms will not have enough time to make use of the nitrogen.
• check that no substances with a high nitrogen content, such as
urine or poultry manure, have been added to the composter.
Stop adding excess nitrogen to the composter.
• do not add ash or lime into the composter.
• check that the bedding used is Biolan bulking material.
• check that you have added a sufficient amount of Biolan bulk-
ing material.
• temporarily increase the amount of bedding added until the
smell disappears.
• mix with the Compostmixer.
