Agriboost™
and nutrient bio-availability
Nutrient uptake by plants involves a complex mechanism
involving physical, chemical and biological reactions.
The root system and the mechanics of nutrient uptake
are not fully understood, yet nutrient flux at the soil-root
interface is central to life in many types of plants
and, more importantly, is the key determinant in crop
yields.
Plants use ion exchange as the principal method for
absorbing nutrients from the soil. This is an active
chemical process initiated by the plant root system,
as nutrients are needed. If nutrients (or water) are
insufficient, the plant naturally spends more time developing
a larger root volume to obtain its needs; this takes
away from plant growth above the soil and retards crop
yields. Therefore, the timing and sufficiency of
nutrients plays a role in plant growth.
When traditional soluble fertilizers are applied to
the soil, mass flow (convective flow of water) is the
method that nutrients move to the root system below
the surface. Since such fertilizers are soluble, they
move through the soil and become available to the plant
roots so long as they are held in the root’s zone
of bio-availability. Also, the root’s demand for
nutrients at any given moment influences the availability
of nutrients in the soil. As such, about 50-70% of nitrogen,
including a similar amount for other fertilizers, moves
through the soil unused by the plant. Generally, the
greater the soil weathering, the lower the concentration
of nutrients in the soil solution. Nutrient uptake efficiency
among the traditional soluble fertilizers is therefore
low, often requiring several applications per harvest,
and leads to the environmental problems associated with
this type of agriculture.
The least understood phenomenon in nutrient uptake
is the cationic exchange process that allows for nutrient
absorption by the plant. All nutrients are absorbed
as ions. Each ion passes through the plasma membrane
into the cytoplasm of the root cell. When nutrients
are needed, the root system uses chemical reactions
to force an ionic imbalance whereby ions are exchanged
between the root system and soil to correct the imbalance.
Because of the many different factors influencing this
process, it is difficult to model among different soil
types, climatic conditions and plant-specific characteristics.
However, cationic exchange is the key method of nutrient
uptake.
Various expensive and often ineffective fertilizers
focus on slowing the dilution of soluble fertilizers
so that they may be available over a greater period
of time. But these and other fertilizers, including
urease inhibiters, miss the point about how plants get
nutrients from the soil. Any meaningful change in nutrient
uptake efficiency has to address the cationic exchange
process on a molecular level. AgriBoost™ products
contain natural minerals and have a very high cationic
exchange capacity (CEC) along with a natural endowment
of trace elements and nutrients important to plant growth.
Because of its molecular structure, AgriBoost™
products can be thought of as a molecular sieve that
readily exchanges ions and can hold other molecules
in its cavity.
In one gram of AgriBoost™,
the channels provide up to several hundred square meters
of surface area on which chemical reactions can take
place. This explains why AgriBoost™ absorbs
and holds water like no other mineral. Naturally, adding
AgriBoost™ to soil dramatically increases soil
moisture even in low humidity environments.
When the plant root demands nutrients through the cationic
exchange process, AgriBoost™ readily gives it
up. This has several important implications for soil
fertility and crop yields. First, nutrients are available
through an entire crop and are made available only as
needed. Second, each unit of nutrient uptake is obtained
with dramatically less fertilizer application, perhaps
as much as 50% less. Third, AgriBoost™
increases soil moisture and is endowed with its own
valuable trace elements and minerals, thereby acting
as a permanent soil re- mineralizer.
