Through its high water retention and slow
release nature, pumice is used for the growth of healthy lawns and the
agricultural production of crops such as tomatoes, strawberries, melons,
cucumbers and lettuce. It is used in greenhouses, hydroponics facilities,
houseplants, home gardens, and truck farms. Pumice, an inert, safe and
naturally occurring mineral is permeable and highly absorbent, which saves
on irrigation expenses. Tomatoes and melons planted in pumice are more
prolific than those grown in amended soil.
Fresh and salt water make
up the most abundant resource on the planet. Although ocean levels are
rising, the amount of terrestrial water used for drinking and irrigation is
rapidly disappearing. Around the world water levels in lakes, rivers, and
aquifers have been declining due to longer drought seasons and water
overuse. Critical circumstances have called for greener technologies and
significant changes in practices that have been common for decades. Due to
modern concerns, many practices have been used to increase soils water
retention. High levels of organic material in soil have proven to raise
water capacity, and new studies have shown that additives consisting of high
porosity volcanic material have achieved even higher levels.
