Reasons to Use Archipelago Bat Guano
More abundant and larger Flowers, Fruits and Vegetables, Strong Root Growth and
Phosphate is essential for plant life in general, and for strong root
growth and plant reproduction specifically. ABG
phosphate should be applied to established fruiting or flowering plants
when they are ready to begin production, and as needed throughout the
production period to obtain the plant’s full potential. ABG
phosphate should also be applied to the soil around the root ball when
any plants are transplanted. This allows the plant to realize its
full root growth potential. When transplanting potted flowers, you
will get a double benefit by applying ABG phosphate around the root ball
– root growth and continued flowering after transplantation. Also,
use ABG phosphate when planting in the spring and fall for hardiness.
Why should you use ABG phosphate instead of an
all-purpose N-P-K fertilizer?
Because your plant does not need all nutrients in the same quantities at
all times. For example, plants need
nitrogen early in the growing season to establish plant size and leaf
growth and to help bring the plant to maturity. But when the plant
is ready to fruit or flower, nitrogen fertilization may inhibit the
plant’s full reproductive potential.
Thus, many authors suggest that you discontinue nitrogen application in
favor of phosphate fertilization while the plant is fruiting and
flowering. To do this, you need a
nitrogen-poor fertilizer such as ABG Phosphate.
But be careful to not over-use this material.
Over-use of phosphate fertilizer has caused pollution of many waterways
throughout the country.
Because of this, there is a growing drive to decrease phosphate use
nationwide. Simple soil tests that can guide
you as to phosphate needs are available through your local university
agricultural extension agencies or other public agencies. Be sure to understand though how
much of the phosphate is present in a form that is available to the
plants. If there is already
plenty of phosphate in the soil, but it is not in an available form, you
probably should work at releasing what is already there. This can normally be done by
decreasing the pH and increasing the organic content of the soil through
application of humate, manure, or compost. Addition of sulfur may be effective
for decreasing pH, but do not over-use that either.
