Organic gardeners prize
bat and seabird droppings—or guano—as a rich
source of natural fertilizers because, unlike artificial
fertilizers, guanos restore a natural balance in the
garden without increasing soil salt content or acidity.
That means beneficial bacteria, insects, and earthworms
will stick around—further improving your soil by
distributing organic matter and aerating the subsoil.
Interestingly, guanos from different regions have differing levels of nitrogen,
phosphorus, and trace minerals. By examining each Sunleaves guano fertilizer
grade—also known as the N-P-K ratio—you can glean the percentage
of nitrogen, phosphorus, and potassium respectively. For instance, Sunleaves
Peruvian Seabird Guano (10-10-2) contains 10 percent nitrogen, 10 percent phosphorus,
and two percent potassium.
You may notice that the N-P-K ratios of Sunleaves guanos are not as high as those
of many synthetic fertilizers, but, in this case, less really is more. That’s
because, unlike artificial products, Sunleaves all-natural guanos are released
more slowly over a much longer period. Because every stage of plant development
requires differing nutrients and nutrient amounts, it’s important to understand
which type of guano to use at which growth stage.
High Nitrogen
Plants need nitrogen to enhance leaf growth and overall vigor. As with Peruvian
Seabird Guano, Mexican Bat Guano (10-2-1) is also high in nitrogen and, as such,
it is particularly well-suited for use with plants in the early phases of growth.
High Phosphorus
The fruiting and flowering phase demands plenty of phosphorus which promotes
healthy root growth. When you supplement the amount of phosphorus your flowering
plants get, you’ll likely notice more blooms and more vigorous growth overall.
Indonesian Bat Guano (0-12-0), Peruvian Seabird Guano, and Jamaican Bat Guano
(1-10-.2) are each high in phosphorus. |
