Limoneira Company recently ran an article in its monthly newsletter about how the ag company uses Agromin compost in its orchards. The results of this compost use have been a dramatic reduction in fertilizers, herbicides and water usage. It's truly a sustainable process. Here's the article.
In 2004, Limoneira Company created a
partnership with Agromin Corporation, a green waste recycler to cities,
counties and commercial growers to transform green waste into safe and cost
effective compost and mulches for use in agricultural production and community
A 10 acre facility on Limoneira
property receives over 200 tons a day of this material that would otherwise be
transported to landfills.
This partnership helps satisfy
California AB 939, the Integrated Waste Management Act that mandates our cities
and counties to divert 50% of their green waste from landfills. The end-product
produced at this facility helps us and other growers to significantly reduce
the use of water, herbicides and fertilizers.
* Green waste is received from
consumers and commercial construction users from the entire Heritage Valley
(Santa Paula to Piru).
* An average of 200 tons/day
processed 5-6 days a week on 12 acres at Limoneira's Orchard Farm facility
between Santa Paula and Ventura. Peak in-take July, low January.
* 70% (140 tons) is green waste-yard
trimmings, grass, etc. and 30% (60 tons) construction materials (wood).
* Green waste contains too much
nitrogen for optimal agricultural production. The carbon from construction
material is needed to optimize this agricultural mixture.
The resulting Agromin mixture
* A healthier root system for
the trees in Limoneira orchards for more efficient nutrient uptake.
* Reduction in agricultural
* Virtual elimination of soil
* Healthier soil through the
addition of organic matter for long term viability
* Less green waste and
construction material in landfills thus reducing 38% of greenhouse gases
emitted from landfills
The Dirt On Dirt
A circle of life,
inter-dependence, balance and renewal. Everything we hold dear is contained
within, dependent upon, and connected to this circle. Soil is the source and
destination of all.
In today's virtual world, too
many of us have lost the ancient awareness of our connection to
soil--forgetting that our health, livelihood and well being are all
inextricably linked to it. This lost connection to our planet's living skin
lies at the root of soil's current global depletion crisis, along with the
other imbalances that our biosphere is now showing us.
The solution is also a circle
... a circle of responsibility, sustainability, and innovation. Soil
sustainability requires a balance between what society demands from soil and
nature's capacity to meet that demand. The solution begins with regained
awareness. Given the right knowledge and product choices, every individual can
make the decision to play a role in returning balance to the circle. Agromin is
dedicated to empowering that choice--a dedication that reflects across every
aspect of our company.
* This mixture shrinks by
30-40% depending upon the moisture content of material and time of year through
a meticulous composting process. The material is spread in 6' height
"wind-rows" and each row is turned weekly with the addition of
moisture for approximately 60 days to aid the composting process.
* By maintaining these strict
standards, we ensure the elimination of any potential viral infection and weed
seeds from the material that would be harmful in the orchards/fields.
* Limoneira's orchards are
testing bi-annually for nutrient content in the soil. Leaf analysis is also
performed. Depending upon specific block needs, approximately 50-200 tons per
acre is spread on the fields to enhance growing conditions and fruit quality.
Limoneira annually places over 35,000 tons of
mulch on only one of its farms in Ventura County. After 3 years, only 20% of
the area of this one farm has been introduced to this process. Therefore, many
more potential benefits can be achieved
