Red Guano is a fertilizer that is formed by the accumulation of seabird excrement, its antiquity easily dates back between 400,000 and 1,000,000. of years and comes in different forms such as dust or camotillo and these depend on the geographical location of its formation. Depending on the years of accumulation, they can be found in a Fossilized, Semi-fossilized or Fresh state.

This fertilizer, apart from the amount of nutritional elements it provides to the soil, its organic matter content, brings with it a series of additional benefits, such as improving its physical characteristics, increasing its aeration capacity and moisture retention.

Fertilizer used for centuries in agriculture.

Benefits of using Red Guano

Red Guano

It is an impalpable, soft powder of a reddish, orange or gray color, and the odor is not very penetrating, although characteristic. Within all the nutrients it has. Phosphorus is the most predominant.

Nitrogenated Red Guano

It is a fertilizer with a high Nitrogen content both in the Ammonia state (NH4), and in the mineral state, NO3, Phosphorus (P), Potassium (K), Calcium (Ca), Sulfur (S).

Premium Red Guano

It corresponds to thick layers of white guano, covered by a layer of camotillo that has allowed this guano to keep its nutritional qualities intact.

This camotillo forms a solid upper layer that has allowed the Guano to converse over time.

The difference in the types of guano is the number of years they are and the concentration of nitrogen it has.

Nutrient Table


Healthy soil is a combination of minerals, rocks, water, air, organic matter (plant and animal waste), microorganisms, including bacteria, fungi and protozoa, and a variety of insects and worms.

This intricate network performs a process that continually replenishes the soil and maintains long-term soil fertility.

For sustained growth, plants require Macro-Nutrients and trace elements. Macro-Nutrients include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S). Trace elements include iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn). For optimal plant growth, the soil must be able to store these nutrients and transfer them to the root surface to be taken up by the plants.

Red Guano

Red Guano is a 100% organic fertilizer formed by the excrement of seabirds fossilized over time on the coasts of northern Chile. It is in itself the noblest of fertilizers and/or fertilizers known throughout the agricultural world, mainly for maintain a balanced amount of nutrient elements.

As an organic fertilizer it contains large amounts of Macro-Nutrients, phosphorus, nitrogen, potassium, calcium, magnesium, sulfur and other minor elements, micro-nutrients such as boron, zinc, copper, molybdenum, etc. Of importance in agricultural soils.

Organic material

This Red Guano, apart from the amount of nutritional elements it provides to the soil, its organic matter content, brings with it a series of additional benefits, such as improving its physical characteristics, increasing its aeration capacity and moisture retention.

Nutritious Elements

Nitrogen Nitrogen primarily favors the growth of shoots, leaves and stems, that is, all the vegetative parts of plants. It is the engine of plant life and is part of protein. The effect of nitrogen is most evident in the observation because the plants provided with this element demonstrate green, lush and fresh vegetation.

Phosphorus Phosphorus plays an essential role in the plant’s assimilation process, promoting abundant flowering and fruiting. Phosphorus accelerates seed formation and maturity.

Potassium Potash has an important role in plant physiology and is involved in cellular metabolism processes, respiration, transpiration and absorption of other elements. Apparently, water absorption and retention are regulated in such a way that increases the plants’ resistance to drought and protects them against the effects of frost. Potash intervenes in the synthesis of carbohydrates and proteins in such a way that it favors the formation of starch, sugar, oils and fats, thus increasing the rigor and resistance to diseases in vegetables.


For sustained growth, plants require macro-nutrients. Which include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S). Trace elements include iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn). For optimal plant growth, the soil must be able to store these nutrients and transfer them to the surface of the roots to be taken up by the plants.

Micronutrients are as important as macronutrients, even though the plant requires them only in very small quantities.
The absence of any of these micronutrients in the soil can limit plant growth, even when


Depending on the objective pursued when applying it, if you want to improve the properties of the soil and its general fertility, the dose varies between 2 and 15 tons per hectare, depending on the type of soil, the duration of the effect and the variety of the crop developed. If you only want to supplement phosphorus deficiencies in crops, the necessary dose will be equivalent to the units of this element (P205).
recommended for each type of crop.

Red Guano Application Table

Red Guano Certifications in English and Spanish, Red Guano, Premium, Nitrogenated

On January 2010, our company received a visit from engineer Heidy Jiménez Padilla, representative of the input evaluation company BCS ÖKO GARANTIE. And since then our products have had compatibility certifications for the use of inputs in organic agriculture, in the following products:

During this visit, random samples were taken from an inventory of over 10,000 bags of different qualities.

This year, our company Guano Rojo Punta Gruesa was granted the recognized confirmations of compatibility for the use of inputs in organic agriculture from the company KIWA BCS ÖKO GARANTIE, in the following products:

Guano Rojo 2024 (inglés)

Guano Rojo Premium 2024  (inglés)

Guano Rojo Nitrogenado 2024 (inglés)

Exploitation method

Under a protective layer of sand, hardened by time, RED GUANO has preserved its nutritional qualities for thousands of years. Given the natural condition, its extractive process was carried out purely manually, due to the difficult places where these guano formations are found. Currently we carry out the process with machinery whenever the terrain allows it.

Steep In order to reach the guano mantle, the protective layer is removed mechanically and the material is extracted and then transferred to the plant, this work is carried out in an open pit.

Bagging, Weighing: All products are weighed and bagged

Warehousing It is then bagged in polypropylene bags with an interior insert and stored for later marketing.

Red Guano Complete Fertilizer

Fertilizers are essential to meet global food needs.

The depletion of nutrients in soils that is seen in many developing countries. Although not visible, it is a major form of land degradation that makes agricultural production unsustainable. Agriculture has been faced with a series of decisions regarding the fertilizer to use.
This problem is mainly due to the high incidence of fertilizer costs.

Simple fertilizers
They are made up of a single active ingredient.

Compound fertilizers
They are made up of several active ingredients, and generally contain the 3 main nutrients.

Guano does not acidify soils, favoring the solubilization processes of nutrients in acidic soils. The phosphorus it contains is rich in phosphates and calcium characterized by a gradual and periodic delivery of soluble phosphates available to plants, making it suitable for all types of annual and permanent crops, especially meadows and fruit trees.

The ranges of both sulfur and calcium, in addition to their fertilizing properties, allow for better gradual solubility of phosphorus in deficient soils and sulfur has action against soil fungi. These characteristics make it recommended in horticultural crops, especially bulbs and tubers (garlic , onion, potatoes, etc.) while the microelements balance the physiological functioning, obtaining optimal performance by promoting the biological activity of the soil, both immediately and gradually.

Unlike most natural fertilizers, red guano due to its fossilized guano character, the organic matter it contains is stabilized (humified) so it is not necessary to apply large volumes to achieve short and long-term effects on fertility. of the soil and crop yield, positively affecting the dose cost per hectare. In addition, it is sold in powder and granules, which makes its application easier.
