This Guano (Mineralized Phosphate) is harvested from the caves of fruit-eating bats that contain deposits that are rich in Phosphorus and Calcium. High-phosphorus bat guano (0-8-0) is a natural fertilizer that can provide numerous benefits to plants and soil health. When used as a granular product, it offers several advantages:

  • Easy to apply: This granulated bat guano is easy to apply evenly to the soil surface. It can be sprinkled by hand or spread using a broadcast spreader or a fertilizer spreader.
  • Increased yield: High-phosphorus bat guano is especially beneficial for cannabis and fruiting plants during their reproductive stages, as it promotes healthy flower development and can increase the overall yield of the plant. This is because phosphorus is a critical nutrient for flower and fruit production, and high-phosphorus bat guano provides a slow-release source of this nutrient.
  • Improved plant health: In addition to promoting flower and fruit development, high-phosphorus bat guano provides essential nutrients that support healthy plant growth. Phosphorus helps plants to develop strong root systems, which allows them to better absorb water and nutrients from the soil. It also plays a critical role in photosynthesis and other metabolic processes that are necessary for plant growth and health.
  • Enhanced flavor and aroma: Cannabis and fruiting plants grown with high-phosphorus bat guano may exhibit enhanced flavor and aroma due to the nutrient-rich soil environment. This is because phosphorus is involved in the production of essential oils and other compounds that contribute to flavor and aroma.

Here are some examples of specific crops that can benefit from bat guano:

  • Cannabis: Cannabis plants require high levels of phosphorus during their flowering stage, and high-phosphorus bat guano is an excellent natural source of this nutrient.
  • Fruit trees: Fruit trees, such as apple, pear, peach, and cherry, also benefit from high-phosphorus bat guano during their fruiting stages.
  • Tomatoes: Tomatoes are heavy feeders and require high levels of phosphorus and other nutrients for healthy growth and fruit production.
  • Peppers: Like tomatoes, peppers also require high levels of phosphorus and other nutrients for healthy growth and fruit production. 
  • Root vegetables: Root vegetables, such as carrots, beets, and potatoes, require phosphorus for strong root development and improved yield.

Overall, high-phosphorus bat guano is an excellent choice for any plant that requires extra phosphorus during its reproductive stages, as it can improve yield, flavor, and overall plant health.
