jpsdad, I'll let you run the numbers.The internet says Goose poop is 2%-4.4% N, 0.1%-1.3% P. and a goose can poop between 1 and 4 pounds of poop daily.
Since geese are grazers, and many pond/lake owners/residents fertilize their lawns, here is some info on grass makeup: Fertilized lawn grass typically maintains high nutrient levels, commonly featuring a nutrient ratio of roughly
4-1-2 (N-P-K) in its leaf tissue. Optimal growth is achieved with 2.75–4.2% Nitrogen (N), 0.3–0.55% Phosphorus (P), and 1.0–2.5% Potassium (K), supporting lush growth and stress tolerance. Or this:
Nutrient content of lawn clippings Processing lawn clippings and tree leaves into the lawn provides nutritional value as well as reduces waste. Generally, turf clippings contain 6-7% nitrogen, 0.5 to 1.0% phosphorous and 2-4% potassium; when returned to the lawn, they can account for a fourth of the lawn's fertilizer applications each year.
How much algae can a pound of P grow?Then the lowest level I found is this:
500 lbs. Algae AdageSo, given those figures, what is the Max/Min amount that can be grown by 1 pound of goose poop and 4 pounds of goose poop?
