WITH THIS PRACTICE, THE OLIVE TREE IS RESTITUTED WITH THE NUTRITIVE ELEMENTS THAT IT HAS USED
Preparatory work on the olive grove for the next season has already begun: floor, herbicides, phytosanitary treatments and fertilizer.
Subscribing is a practice with which it is intended to restore to the olive tree the nutritional elements used to:
Produce harvest – Growth of vegetative organs (estate, sprouts, leaves) – Growth and maintenance of old vegetative organs (trunk and branches).
The soil cannot supply the necessary elements for these tasks in the adequate time., and that is why compost must be supplied. To make these contributions it is necessary to know the extractions of the olive tree per ton of fruit produced and the extractions by growth of the vegetative organs, as well as the consumption of spontaneous vegetation.
The base of the fertilization of any vegetable is formed by Nitrogen, Phosphorus and Potassium. These three elements are what plants need in large quantities. Other elements such as boron, magnesium, manganese, sulfur, football, iron, copper and zinc are also required, although to a lesser extent.
Nitrogen is very dynamic, dissolves and washes away if rainfall is very heavy; it evaporates if it doesn't rain, is mineralized from organic matter, is fixed by bacteria in the soil, etc.
Phosphorus and potassium present the problem of being part of the soil structure, so even being present in apparently normal amounts, they are not assimilable by the plant. That is why we must contribute them every year, especially in very limestone soils such as ours.
For all these considerations and others that for space are not indicated, it is always better to pay with complexes, or in the case of applying urea, add potassium via foliar.
The fertilizers must be distributed during all the months of vegetative development (March to October) taking into account that from March to May the maximum needs are for nitrogen and from June they are for potassium. Foliar application, in rainfed and years of low rainfall, you have to have it as an effective alternative.
To end, we must distinguish between foliar fertilizers, with an important richness in macroelements (nitrogen, phosphorus and potassium) and other nutrients, like Abofol, and biostimulants, like the Isabión and the Siapton, whose mission is to activate internal mechanisms of the olive tree to use its reserves, recovering the plant from stressful situations caused by drought, frost, diseases, etc. and improve the absorption of other nutritional elements.
