Results with bat guano |
| Cuba |
Orange trees |
Yields increased from 300 to 500 oranges per foot in the 1st year, and to 800 oranges per foot in the 2nd year |
| Martinique |
Citrus |
Over 20 years of using artificial fertilizers and pesticides had left production low, with the soil weak and diseased with acarina. The application of 10 kg of guano per seedling significantly restored the soil and improved harvest quality. |
| Cuba |
Banana |
Degraded, nematode-infested soils had led to weak harvests, but the application of guano improved soil conditions and reduced the incidence of nematodes by half. |
| Martinique |
Flowers and plants for commercial agriculture |
Plants exhibited brighter colors and a generally better quality after bat guano was introduced to the soil. |

Seedlings increased by more than 20% in quantity, more than 40% in height, and more than 30% in dry weight, when guano was applied. |
