Olive growing is one of the most representative agricultural traditions in Spain, especially in regions such as Andalusia. Apart from being the basis of one of the most important olive oil productions in the world, olive trees require specific care to obtain a high-quality harvest. Adequate fertilization plays a key role in the development and health of the olive tree. In this article, we explain which are the most suitable fertilizers for olive trees, the importance of using organic products and, in addition, we present the best fertilizers from the BH Terra catalog for this crop.
The need for fertilization in olive cultivation
The olive tree is a plant that adapts to diverse climates and soils, but, like all crops, it has nutritional needs that must be met to ensure optimal growth and good fruit production. Among the main nutrients that the olive tree needs are nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). In addition, micronutrients such as boron, iron and zinc are also essential for the healthy development of the plant.
The olive tree has a specific need for nutrients throughout its life cycle, from the budding phase to the formation of fruit. If the soil does not provide enough nutrients naturally, it is necessary to use fertilizers to help compensate for these deficiencies.
Chemical fertilization vs. organic fertilization for olive trees
Traditionally, chemical fertilizers have been the most commonly used option for feeding olive crops. However, in recent years, more emphasis has been placed on organic fertilizers, which are more beneficial to the environment and offer long-term advantages for olive cultivation. The choice of fertilizer type depends on various factors such as the type of soil, the irrigation system and the type of cultivation (conventional or organic).
Chemical fertilization
Chemical fertilizers, such as nitrates and phosphates, are widely used due to their rapid action and immediate availability of nutrients. However, excessive use of these products can lead to soil degradation, groundwater contamination and loss of biodiversity. In addition, chemical fertilizers tend to modify the soil pH and can have negative effects on the health of microorganisms that inhabit it.
Organic fertilization
Organic fertilizers, such as compost, manure, or green fertilizers, are more sustainable and environmentally friendly. These fertilizers release nutrients gradually and help improve soil structure, promoting water retention, microbial activity, and long-term fertility. In olive cultivation, the use of organic fertilizers has additional benefits, which we explore below.
Benefits of organic fertilizers in olive cultivation
Improves soil structure
The use of organic fertilizers such as compost or manure improves the soil structure, promoting aeration and drainage. This is especially important in compacted soils, which can hinder the growth of olive tree roots. By improving the structure, the absorption of water and nutrients is facilitated, which favors the development of the tree.
Increased microbial activity
Organic fertilizers enrich the soil with organic matter that feeds the beneficial microorganisms present in the soil. These microorganisms, such as bacteria and fungi, play an essential role in breaking down organic matter and releasing nutrients naturally. This helps create a healthier environment for the olive tree and reduces the dependence on chemical inputs.
Lower risk of contamination
Because they are biodegradable, organic fertilizers have less risk of polluting water resources and the environment. This is especially important in areas of intensive olive cultivation, where runoff from chemical fertilizers can cause pollution of nearby waters.
Better long-term sustainability
The use of organic fertilizers contributes to the long-term sustainability of olive cultivation. These fertilizers not only cover the immediate needs of nutrients, but also improve soil fertility naturally and progressively, ensuring a healthy and abundant harvest in the years to come.
Best fertilizers for olive cultivation: BH Terra
BH Terra is a brand recognized for its catalog of high-quality organic fertilizers, which adapt to the needs of various crops, including olive trees. Below, we present some of the best fertilizers from the BH Terra catalog that you can use in olive cultivation to ensure optimal and sustainable performance.
This organic fertilizer is ideal for olive tree cultivation because it combines essential nutrients such as nitrogen (N), phosphorus (P) and potassium (K), which promote overall plant growth, root development and fruit formation. This organic fertilizer is also rich in organic matter, which improves soil structure and water retention capacity, crucial for olive trees that are often found in dry soils.
BH Terra Organic NPK fertilizer is formulated to release nutrients gradually, allowing the olive tree to make better use of resources over time and reducing the risk of leaching, resulting in better use of the fertilizer.
BH Terra Liquid Seaweed Fertilizer
BH Terra liquid seaweed fertilizer is an excellent option for olive tree cultivation, especially during critical growth stages such as flowering or fruit setting. This fertilizer contains seaweed extracts, which are rich in micronutrients such as boron, magnesium, iron and calcium, essential for the proper development of the olive tree.
This fertilizer not only nourishes plants effectively, but also improves the plants’ resistance to adverse weather conditions such as drought or excessive heat.
Olive cultivation requires special attention to plant nutrition, and fertilization plays a crucial role in ensuring a plentiful and quality harvest. Organic fertilizers, such as those offered by BH Terra, are an excellent option for this crop, as they not only improve plant health, but also promote sustainability and environmental preservation. From compost and guano to worm humus and liquid fertilizers, BH Terra offers high-quality products that are perfectly adapted to the nutritional needs of the olive tree, helping to maintain fertile and healthy soil in the long term.
