BioGuano: Mother Natures Best Fertiliser!

on January 28, 2023

BioGuano+ is an organic fertilizer made from seabird dung. It provides essential nutrients for healthy plant growth, plus the added benefits of increased soil fertility and improved crop yields. Find out why BioGuano is Mother Nature’s Best Fertiliser, and why you should use it!

What is BioGuano+?

The word Guano originates from the South American Andean Indigenous language, meaning “the droppings of seabirds”. Thanks to the fish diet of seabirds, their guano is a highly effective fertilizer. Once seabirds have consumed and digested the saltwater fish, their droppings are then deposited on rocks and baked in the sun, the excrement along with remains of eggshells, feathers, insects, and microbes, matures over thousands of years into Mother Nature’s Best Fertiliser.

The Benefits of BioGuano+ as an Organic Fertilizer.

Are your plants struggling to fruit or flower? Try out some BioGuano+.

Australian Certified Organic (Input No. 13250) BioGuano+ is a sustainable, long-term organic fertilizer choice. It acts quickly, breaking down in the soil to release essential nutrients needed for strong, healthy plant growth. BioGuano+ also improves soil quality and helps with water retention, which allows plants to get more of the moisture they need. Finally, BioGuano+ has the potential to increase crop yields significantly compared to traditional fertilizers, resulting in sweeter agricultural and horticultural yields!

Uses of BioGuano+

BioGuano+ is suitable for both indoor and outdoor plants*, grown in soil, premium potting mix, coconut coir or hydroponic systems. It can be used to create a foliar spray to strengthen foliage against environmental stress and damage from pests and disease. Also, as a complete organic flowering & fruiting fertilizer, a high-quality organic flowering additive, and as a natural soil conditioner and soil microbe feeder.

It Contains All the Essential Nutrients for Growing Plants.

BioGuano+ has been formulated with five essential nutrients that are vital for plant growth. These nutrients include:

  • Nitrogen – Although BioGuano contains very little Nitrogen, the amount it has can still promote leaf growth.
  • Phosphorus – An essential plant nutrient for successful flowering and reproduction.
  • Potassium - Promotes fruiting and flowering.
  • Calcium – Provided in a beneficial ratio to help build the soil. With the right amount of available calcium in the soil around the root hairs, the uptake of other nutrients in the soil will be more effective and efficient.
  • Magnesium – Help to maintain chlorophyl within the foliage and prevent yellowing. Peppers and tomato plants benefit from magnesium.

Is BioGuano+ Safe to use with Australian Native Plants?

Native plants are very sensitive to Phosphorus and too much may result in your plants demise.

According to the BioGuano+ manufacturers: "around 90% of the natural Phosphorus in the fertilizer is present in the citrate-soluble and citrate-insoluble form and is slowly available through the action of root enzymes and fluids emitted through the roots of plants. In this way, the Phosphorus in BioGuano+™ is liberated when the plants’ need it most and at a rate that mirrors the developing root system and growth rate of the plant. BioGuano+™ used at label rates will not harm mycorrhizal fungi or other soil biota."

Some plants such as Grevilleas, Hakeas and some Kangaroo Paw species have adapted in Australian soils to cope with low Phosphorus levels, therefore are known to be more sensitive to additional Phosphorus applications. BioGuano+ advise growers not to apply BioGuano on these three groups of Australian Native plants. For complete application rates and directions, view the BioGuano+ label on the 1 and 5 Litre bottles
