research, has proven to typically be
within the top 18 inches of soil. This
is especially true for the young roots
that are highly active in feeding,
Brown explained.
So, how can growers ensure
fertilizer applications remain within
the active root zone? Brown said this
depends on the integration of how
and when an orchard is fertilized and
how and when it is irrigated.
" Your goal optimum irrigation is a
fertilizer application towards the end
of the irrigation event so that you don't
push it through the profile, " Brown
said. " This is another example of where
having small, spoon-feeding applications
minimizes the potential of pushing
the nitrogen through the profile. "
Less is more
This " spoon-feeding " method is
known as continuous fertigation
(fertilizing with every irrigation)
as opposed to episodic fertigation
(fertilizing once every month or two).
If there is too much excess caused
by episodic fertigation, that is where
inefficiencies occur causing leaching
or gaseous nitrogen losses, which can
come with a number of implications
for the air resources board and grower.
Another factor that needs to
be considered is how irrigation
distribution uniformity determines
nitrogen distribution uniformity.
" If you have a very uniform
irrigation system, you inject 250
pounds of nitrogen in a year, and
you will be able to deliver that
250 pounds uniformly across the
orchard, " Brown said. " If you have a
distribution uniformity that's poor,
not only are you not distributing
water uniformly, but every time you
do an injection of a fertilizer, you're
also not distributing the fertilizer
uniformly. "

relationship between irrigation
and fertilization, the ABC
built the California Almond
Stewardship Platform (CASP).
For more information on CASP,
visit almondstewardship.org. The
platform offers growers tools as it
relates to their operation and can
run iterations based on customizable
inputs. Using the solutions
computed by CASP, growers can
determine the best path for an
individual orchard.
It's well recognized that continuous
fertigation requires dedicated
equipment and constant vigilance
from the grower. However, the
investment will be worthwhile when
efficiency savings and productivity
boosts are taken into consideration,
Brown assured.
" It's very clear that for profitability,
efficiency, lack of nitrogen loss, and
environmental considerations, that
continuous fertilization strategies are
the secret to success, " he concluded.
