The Fertilization of Oud Trees

As the human needs a balanced nourishment, the tree needs nutrients that support its growth and its health. But the talk of the fertilization of oud trees is not a call to increasing the fertilizer, but a call to the studied nutrition founded on a real need, not on conjecture. In this article we present a general educational overview of the nutrition of the oud tree and the role of the macro and micro nutrients in it, in descriptive, reserved language, without claiming an engineering expertise in fertilization or describing specific nutrition programs.

Why does nutrition matter?

The tree is a living being that builds its tissues and continues its growth by relying on nutritional elements it draws from its surroundings, from the soil, the water, and the air. And oud trees, like the rest of the trees, need a measure of these elements to grow a healthy growth and preserve their vitality. From here fertilization comes among the axes of the cultivation of oud trees as one of the faces of the care that may support the tree, when it is built on a real need.

Yet the essential idea we would establish from the outset is that nutrition is not "the more it increases, the better." The tree does not benefit from fertilizer as is supposed sometimes by the measure of what is thrown to it, but by the measure of what it actually needs and what it can benefit from. And the increase over the need may turn into a harm, as we will show later. The matter is a matter of balance and suitability, not a matter of abundance and plenty.

And the talk of nutrition does not separate from the talk of the soil in which the tree grows; the soil is the first repository of the nutrients, and its natural fertility may suffice the need of the tree or fall short of it according to its state. This is why this article connects closely to what we addressed about the suitable soil for oud trees, since the decision of fertilization is not understood except in the light of what the soil provides in the first place and what it lacks.

The macronutrients

It is mentioned in the science of plant nutrition generally that the plant has macronutrients it needs in relatively more abundant amounts, at the head of which are three known elements: nitrogen, phosphorus, and potassium. And each of them has general roles in the life of the plant: nitrogen is usually connected to the vegetative growth and the structure of the leaves and the new tissues, phosphorus is mentioned in the context of the roots and the energy within the plant, and potassium is connected to the general sturdiness and the regulation of biological processes in the tree.

And we affirm here that we describe general roles as they are circulated in plant nutrition in general terms, not as they apply to the oud tree with particular numbers. We do not mention any proportions between these elements, nor amounts of any of them, because that is among the most precise of what differs with the difference of the soil, its state, the age of the tree, and the stage of its growth. And any number we cite here may be understood as a "recipe" when it is not so, but may harm whoever applies it to a soil that does not suit it.

What is intended conceptually is that the tree needs these macro elements within its nutrition, and that the lack of one of them may be reflected on its growth, just as its excess may disturb the balance. As for the balancing between them, and determining whether the soil suffices them or they need support, it is a technical matter not decided except by knowing the state of the soil itself, and it is the work of the agricultural specialist, not the work of the one who describes the general scene.

The micronutrients

Alongside the macro elements, it is mentioned that the plant has micronutrients it needs in very slight amounts, but the slightness of the amount does not mean the slightness of the importance. These fine elements enter into biological processes within the plant, and the lack of one of them, even if it were slight, may show its effect on the health of the tree despite the smallness of what it needs of it. And among their examples circulated in plant nutrition are elements such as iron and others of the elements the plant needs in small measures.

And we abide here by the same caution: we do not mention amounts nor proportions for these micro elements, nor do we assert that the oud tree needs this element or that in a particular measure. The plant's need for the micronutrients, and their availability in the soil in the first place, are among the most precise of the matters not known except by a laboratory test of the soil or of the plant, and the soil may be rich in them so the tree needs no addition.

The general principle, then, is that the complete nutrition is not confined to the three macro elements, but includes a wider system of the micro elements that complete the plant's need. Yet this does not mean that the farmer must add them all; the random addition of elements that are not lacking in the first place may be without benefit or of harm. And the decision in that returns to what the inspection of the soil reveals, not to a general rule applied to every case.

Organic versus mineral

A distinction is usually made in fertilization between two main types: the organic fertilizers such as compost, decomposed animal manure, and plant remains, and the mineral fertilizers, the manufactured ones that provide nutritional elements in a concentrated form. And each of the two types has roles that are spoken of and advantages and limits. The organic fertilizers are mentioned generally as improving the structure of the soil, its life, and its content of organic matter over the longer term, besides what they add of nutrients in a gradual form.

As for the mineral fertilizers, they are mentioned as providing specific elements in a faster and more concentrated form, which may be beneficial when a certain lack is to be filled. But this concentration itself makes them more in need of caution, since exceeding in them is easier and its effect faster in bringing about a disorder or a harmful accumulation. And we do not put forward here a decisive preference between the two types, for each of them may have its place according to the state of the soil and the aim, and many practices gather between them.

And we put all this forward as a general description of circulated roles, not a technical recommendation we issue. The choice of the type of the fertilizer, its amount, and its timing are among the matters that depend on the soil, the plant, and the local conditions, and we refer their evaluation and their detailing to the people of specialization who balance between the characteristics of each type and the actual need of the land. As for us, we content ourselves with the introducing that each has a role, without preferring or describing measures.

The dangers of over-fertilization

If this article has a single message that deserves to be preserved, it is that over-fertilization may harm more than it benefits. Contrary to what may be supposed, adding more fertilizer is not a guaranteed way to a stronger tree. The amounts in excess of the tree's need may accumulate in the soil in the form of salts that harm the roots, may disturb the balance between the elements so they impede the absorption of some of them, and may pollute the soil and the surrounding water. This is why it is circulated that the calculated frugality is safer than the extravagance.

And this principle — that the less is safer when in doubt — is not a call to deprivation, but to the moderation built on a real need. The tree that finds in its soil what suffices it does not benefit from an additional fertilizer thrown to it, but may be harmed by it. From here the safe entrance to fertilization was that we begin from the question: does the tree actually need? And with what specifically? Before we begin from the question: how much do we add?

And we avoid here, as is our habit in this guide, mentioning any numerical limits for the excess or the safety, because they differ with the difference of the fertilizer, the soil, and the tree. We content ourselves with the principle that guides the decision: fertilization is a tool used in measure at the need, not a habit practiced in abundance in every case. And whoever exceeds supposing that he does well may harm the tree and the soil from where he wanted their benefit.

Soil testing guides the decision

So how do we know what the tree actually needs? The honest answer is that that is not known by conjecture nor by imitating what others do, but is known through soil testing. The inspection of the soil and its analysis is what reveals its actual fertility and what it contains of elements and what it lacks, and from it the decision of fertilization sets off if the need calls for it. Instead of adding elements that may be present in the first place, we build the decision on knowledge, not on assumption.

And for this reason specifically we refrain in this article from presenting any general "recipe" for fertilization; there is no single recipe that suits every soil and every tree, because the starting point itself — the state of the soil — differs from one location to another. What a land poor in a certain element needs may be harmful to another land rich in it. And the test is what distinguishes between the two cases, and general talk however detailed does not dispense with it.

And nutrition also connects to water closely; the nutrients do not reach the roots except dissolved in the water of the soil, and the management of irrigation affects their availability and their leaching. And we have devoted to this aspect an independent talk about the irrigation of oud trees that integrates with this article, since the water and the nutrition connect in a single system in which one is not separated from the other. And in all that the reference in the measurement and the decision remains the agricultural specialist and the extension services that inspect the soil and the water together.

The conclusion

We can abridge the whole talk of fertilization in a single principle: feed the tree based on evidence, not on conjecture. The tree needs macro and micro nutrients to grow a healthy growth, and the organic and mineral fertilizers each have their role, but the excess may harm, the natural fertility may suffice, and the test alone is what reveals the real need. Wise fertilization is a frugal care guided by knowledge, not an abundance thrown without reckoning — and the detailing of all that, its reference is the people of specialization, not a supplier describing the general principles.

As for if you are a reader interested in oud as a product, not as a cultivation, the conclusion that concerns you is simpler: good oud is the fruit of a tree that grew in a fertile soil and a balanced care, then your turn comes in the goodness of choice. And for whoever wants to distinguish the authentic from other than it, we have set a practical guide in how to choose authentic Indonesian oud that helps you to choose with confidence, and better than that is that you try for yourself, so you begin with a sample of oud by which you test the scent, the origin, and the grade before you commit to a quantity.
