What is Compost ?

Compost is a substance, or product, that can be of inorganic or organic origin and that is used to improve the quality of the soil, adding nutrients for crops and plantations. Manure and guano are natural fertilizers of ancestral use (there are also processes that imitate the latter).

What is Compost Good For ? Benefits, Uses and Applications

Compost makes it possible to use organic waste in an environmentally sustainable way. Its use increases the microbial activity of the soil, recovering organic matter, contributing to the retention of nutrients and allowing the fixation of carbon to the soil. In addition, it also improves the water absorption capacity.

When it comes to enriching the soil substrate, organic fertilizers provide a variety of essential nutrients, so that plants develop without problems. Nitrogen, phosphorus and potassium stand out in this regard. Additionally, they help the regeneration of microorganisms – fungi and bacteria – that strengthen the natural composition of the soil, helping plants to grow strong and healthy.

Use of Compost

Compost is commonly used in extensive plantations, as well as gardens and pots to strengthen and nourish the composition of the earth, providing benefits to the growth of plants.


As necessary, compost can be applied on the surface or bottom, depending on the particular case, it is applied by digging the earth and stirring it with it.

In Pots and Planters

Just sprinkle a modest amount of compost on top.

In Planting Trees and Shrubs

It is mixed with the soil when planting the tree or shrub in the soil of the garden or farm. If the substrate has lost texture and structure, it is advisable to partially renew it, or even change it if the plant resists a transplant.

What is Organic Compost ?

Organic compost are substances made from animal excrement, plant waste, or a combination of these. They are added to the soil in order to reinforce or recover its physical and biochemical characteristics.

Organic fertilizers not only provide nutrients to the soil, but also favor its structure. In addition to providing nutrients, they modify the population of microorganisms, in such a way that the formation of aggregates is ensured that favor better water retention, gas exchange and nutrients, at the level of the roots of the plants.

Types of Organic Compost

There are a variety of organic compost, highlighting the following:

Compost: produced from waste such as egg shells, fruit and vegetable remains, coffee, etc.

The Worm Humus: is a type of compound that is obtained from the digestive process of worms.

Wood Ashes: no aggregates such as paint or enamels.

Green Compost: generated by the plants themselves.

Manure: generated with the fermented feces of animals.

Guano: which is generated from the droppings of birds and bats.

La Peat: in its blonde and black forms.

What is Green Compost ?

It is plants, generally legumes, that are cultivated and then cut and buried. Being in the decomposition stage, they release nutrients, especially nitrogen that act as compost.

The use of these types of plants, either individually or in combination, usually produces rapid growth, which precedes – or succeeds – commercial-scale crops. The use of green compost aims to improve the physical and biochemical condition of the soil, as well as its structure, acting mechanically on its roots, which leaves the soil aerated, light and easy to work with.

They are ideal for depleted soils, poor in nutrient content, unstructured, compacted; improving the circulation of water and air, and protecting them from erosive and drying processes.

Difference between Compost and Fertilizer

It may be difficult for you to distinguish between them, since both substances have very similar characteristics and are used with the same objective: to take care of our crops, pots and gardens.

When exploring information about compost and fertilizers we often find that the main difference between these substances is that compost improves the composition of the soil, while fertilizers nourish the plant for productive growth.

Another distinction that we find refers to the frequency of use of each one. In this sense, the fertilizers will be used once or twice in the preparation of land, while fertilizers are applied continuously.

Organic Compost

Organic compost are those formed from natural elements, such as bacteria, worms, fungi, and insects. Living soil is fertilized by such natural elements in a sustainable way.

Mineral Fertilizers

Mineral fertilizers, commonly called chemical fertilizers, are only partially made of natural materials, as they are processed in combination with other chemical components. However, some of the elements that can be found in these also exist in the natural environment.

Importance Of Compost

Compost helps to promote the essential bacterial life that nourishes the soil, feeding the plants. There are three macronutrients required by all plant beings:

Nitrogen: Essential for growth.

Phosphorus: Helps in the ripening of flowers and fruits, and strengthens the development of the roots.

Potassium: Whose primary function is the transport of nutrients, in addition to stimulating the formation of more resistant tissues.

Despite the above, we must always keep in mind mineral micronutrients, such as calcium, iron and magnesium. Without these, the plants begin to turn a yellowish color, lack flower, or less regularly to flower. For this reason, it is essential to fertilize the soil regularly to enjoy healthy plants.

How is Compost Prepared ?

There are various methods for preparing compost. The ideal, and simplest, is to stack different organic materials in layers, interspersing green vegetable scraps, manure, kitchen scraps, straw, dirt, and so on. The pile is watered generously to ensure its humidity, and protect it with some wrapping material (plastic or sheet metal), to prevent the rains from damaging the proper «fermentation» of the preparation.


If no worms appear in the compost, you may need to add some.

Final Words

Plants, like animals, need natural nutrients to grow healthily. Compost and fertilizers are components that, well managed, ensure that strong and healthy growth. They are the vitamin complex for plants, especially for ornamentals.

As is often the case with all natural processes, the use of fertilizers for soil fertilization should avoid excesses, in time and in quantities, since they can turn out to be counterproductive and affect the quality of the crops, and even modify the level of acidity. in the soil, which is part of its vitality to germinate.
