Improvement and drainage of lawns
Especially in hot climate areas loss of water increases
due to high evaporation at surface-irrigated
agricultural-green areas and greenhouses. In the
countries with limited water resources pumice usage is
increasing for the purpose of minimizing water
consumption, increasing the efficiency of consumption,
minimizing the amount of alcali which is increasing as a
result of evaporation especially in calcareous water.
The upper layer of soil (depending on the type of plant)
is taking off in a certain depth a drainage layer is
formed under the soil by spreading and padding the
pumice and re-covering the soil. In this application
which the irrigation can be made directly through pipes
through this layer, soil takes the necessary water
inside from the pumice layer and it reaches the plant
roots in this way. By the irrigation which is done in
this way evaporation of irrigation is minimizes,
consumption of water is decreased and in addition to
that irrigation can be done at any time of day. Israel,
Saudi Arabia, Dubai, Qatar and countries like that which
has limited water resources and fertile lands can be
shown as the best practice examples.
The roots of plants are living organisms requiring a
continual supply of oxygen, the introduction of air into
the soil even though it is wet is very important.
Likewise, roots are constantly releasing carbon dioxide,
(via respiration), which must be removed from the root
zone. Plants require that these gases be supplied or
exhausted via soilpores. Thus, a good soil must be
porous to permit the exchange of gases while also
adequately retaining water to meet the needs of the
plant. Additionally, the plant must obtain more than a
dozen elements from the soil for its growth.
Clay or dense soils are so compacted that their
structure does not allow outside nutrients and moisture
to penetrate to plant roots, thus, leaving the plant
deficient. Pumice has excellent drainage characteristics
similar to coarse sand. It is most important that soil
has a relatively high air space after drainage. Pumice
compares very favorably with organic amendments in this
respect. Clays are notably low in this property.
Leaching of excess soluble salts is no problem with
adequate pumice incorporated, when it becomes necessary.
Where bark or other wood residuals are employed, it is
always desirable to fumigate or steam in order to avoid
possible pathogen introduction.
Pumice stone is perfectly suitable for soilless
cultivations of tomato, cucumber, pepper, rose, gerbera,
gypsophila, carnation, chrysanthemum and other
vegetables and flowers. For all these reasons, pumice
stone has become a very interesting substrate for
hydroponic cultures in most countries.
Extensive research has shown that foliage plants thrive
in an organic type soil which has high aeration and
retains moisture well. A mixture of one part pumice to
one part leoanrdite by volume will grow luxurious plants
if properly fertilized. Flowering pot plants will grow
well in a mix containing one part pumice, one part
leoanrdite, and two parts bark by volume. Starting
annuals in flats or pots can be accomplished with
success by using the mixture for flowering pot plants.
In establishing new lawns, it is used in preparing the
seed bed, incorporated in the soil and also for mulching
the seed. Pumice will have no objectionable odor as
steer manure has. It will not compete for the nitrogen
in the soil as the organic materials, (such as sawdust)
when they breakdown. In established turf, it can be used
as a top dressing after aerification, especially on golf
greens. The heavy traffic and use of machinery causes
compaction, the destruction of pore spaces in the soil.
Aerification and use of pumice (which does not decompose
or pack) will restore the soil structure and make
possible better root growth.
Pumice is an effective mulch in shrub and flower beds.
It is a type of mulch that has aesthetic as well as
practical value in gardening. The soil beneath the mulch
stays moist for a longer period and does not compact due
to overhead watering.Pumice will not breakdown so there
is never a replacement problem. A mulch 5 to 6 cm thick
effectively minimizes weed problems. As a mulch it is
also an ideal insulator, it will prevent temperature
rise in the root zone, making it possible for continual
growth activity even under extremely high temperature
conditions, it has been successfully used in Palm
Springs to maintain lawns throughout the summer in
A Green Rooftop consists in all or part of the surface
area of a rooftop or a balcony that has been planted
with vegetation in order to upgrade the environment or,

Increase green spaces in urban environments,
Reduce the effects of the "urban heat island" effect (UHI),
Reduce noise pollution,
Increase buildings' energy efficiency and Cut down on
A green rooftop is a special multi-layer system
consisting of a growing medium, an irrigation system and
vegetation. Green rooftops are also known as living
roofs and roof gardens
