Guano is a word that originates from the Andean indigenous language, and means, “the droppings of seabirds”. The guano production process begins as saltwater fish are devoured and digested by sea birds. Deposited on rocks and baked in the sun, the excrement along with bits of eggshells, feathers, insects and microbes matures into nature’s best fertiliser. Guano cleans toxins from soil, improves soil texture, speeds up the decomposition process and promotes healthy plant colour and growth.


BioGuano+ contains the essential nutrients you need for all stages of plant growth in a simple, easy to use liquid form that is an Australian Certified Organic “Certified Allowed Input No. 13250”. BioGuano+ not only gives you the nutrients that your crop requires, but also improves soil quality at the same time resulting in short and long-term benefits. The addition of Kelp improves plant growth, flavour profiles, tolerance to abiotic/biotic stress and root/microbe interactions. Supercharge your nutrient regime with BioGuano+.

BioGuano+ is a concentrated liquid seabird guano fertiliser. Blended with Potassium (K), Sulphur (S), Magnesium (Mg), Silicon (Si), seaweed, fulvic acid and trace elements. Our hi-tech milling equipment grinds the guano down to 5 microns providing a relative density of 1.6 SG. This process ensures BioGuano+ remains in solution and won’t block drippers or drip emitters.

High Density Profile:

Bio Guano provides a relative density profile of 1.6 SG. Once blended in water, this super concentrate liquid fertiliser solution provides more guano per millilitre than competing guano products. While remaining in solution for efficient application.


BioGuano+ is an organic liquid that is rich in Calcium (Ca = 13.3%), Phosphorus (P = 6.26%), Potassium (K = 1.57%) and Magnesium (Mg= 1.49%) as well as a host of other micronutrients. No two soils are the same. Available Calcium and Phosphorus are among the two most deficient soil nutrients. Both are essential to the long-term health of your soil.

BioGuano+ Mobilises Phosphorus:

Phosphate that is tied up in the soil as Calcium Phosphate, Iron Phosphate or Aluminium Phosphate is freed up for adsorption by the plant when silica is added. The silica preferentially forms Calcium Silicate, Iron Silicate and Aluminium Silicate allowing the phosphate to be taken up by the plant.

Irrigation Compatible:

Our hi-tech mill grinds the guano powder to achieve a sub 5-micron particle size. Bio Guano is 100% compatible with all leading boom spray, tillage injection and fertigation equipment.

BioGuano Contains Fulvic:

Fulvics are small highly charged molecules that, due to their carboxylic and phenolic functionalities are excellent chelators of nutrients (metal ions) to provide increased ion exchange.

BioGuano Contains Kelp:

The addition of Kelp further provides a combination of both macronutrients, (N, P, and K) and micronutrients (Ca, Mg, S, Mn, Cu, Fe, and Zn). It also contains cytokinins, auxins, gibberellins, betaines, mannitol, organic acids, polysaccharides, amino acids, alginates, and proteins, all of which improve plant growth, flavour profiles, tolerance to abiotic and biotic stress and root microbe interactions. Kelp also greatly facilitates the uptake of available micro nutrients.

BioGuano Contains Silicon:

Silicon availability in terrestrial soils (especially those used in intensive agriculture) is potentially declining due to effects of ecosystem management, and the yearly withdrawal by crop harvest (given that many crop plants are Si accumulators). Silicon is the perfect background element for BioGuano+ and serves numerous purposes. Cells are the building blocks of a plant’s framework. Silicon can increase the rigidity of plant cell walls and strengthen branches to better support large fruits and flowers associated with modern plant genetics. Stronger cells form thicker stems. The thicker cell walls create bigger stalks with bigger pathways that uptake and transport more water and more nutrients. This fortifying, synergistic effect will help to facilitate bigger plants, faster growth, and protection against sap sucking insects. Plants also express increased resistance to various pathogenic fungi such as grey mould and powdery mildew.

Silicon is also used to stabilise and increase the dispersion rate of BioGuano+. This stops it inherently sticking to itself after the fine milling process, which ensures more consistent application is achieved.

BioGuano Contains Calcium:

Healthy soil requires a predominance of its available colloid sites occupied by Calcium; this amount varies depending on the soil type. A light sandy soil requires slightly less Calcium but more Magnesium to bind the soil together, while a heavy clay soil can cope with slightly more Calcium and less Magnesium to facilitate better drainage. Ideally a ratio of Ca:Mg 60:20 for light sandy soil to 70:10 for heavy clay soil is ideal (Kinsey) and liquid BioGuano+ provides these available nutrients in a beneficial ratio to help build the soil. Feed the soil and the soil feeds the crop. With the right amount of available Calcium in the soil and around the root hairs, the uptake of other nutrients will be more effective and efficient. Liquid BioGuano has the right amount of Calcium, Magnesium, Phosphorous and Potassium. Coupled with a high C:N ratio of 33:1 to build soil carbon (2.5%). BioGuano+ will feed soil bacteria and microbes to build even healthier soil to feed your crop. Grow strong healthy plants and increase yield.
