Nutrients Needed for Palm Trees


Nitrogen is an extremely important substance in plant fertilizers. When you buy fertilizer for any plant, including Palm Trees, the first feed component you will see is Nitrogen.

Nitrogen holds immense importance for every plant, making up about 3% to 4% of its structure, more than any other mineral. Nitrogen is one of the prime promoters of a plant’s growth and development.

Nitrogen helps the Palm Tree grow by enabling it to form amino acids. The amino acids are the building blocks of proteins, which are involved in a plant’s metabolic and growth activities.

It is a major component of chlorophyll, the compound that plants use to trap sunlight and produce appropriate sugars by the process of photosynthesis.

Without Nitrogen, the plants cannot synthesize proteins and will ultimately die. These proteins are either significant structural units of the plants or act as enzymes, allowing them to carry out the biochemical processes required for living.

Nitrogen helps the Palm Trees from ATP (Adenosine Tri-phosphate), the basic compound of energy, making it possible for the plant to perform all its natural cycles.

Moreover, Nitrogen is an important constituent of DNA, the genetic material that helps plants grow and reproduce. Conclusively, for plants, Nitrogen is the key to life. Without it, the plants cannot function normally.

To summarise, nitrogen is an essential need for plants so make sure that you provide your palm trees with enough nitrogen so that they can continue growing happily and healthily.


The role of phosphorus in plants is very important. It helps a plant convert other nutrients into usable building blocks with which to grow. 

Phosphorus is one of the main three nutrients most commonly found in fertilizers and is the “P” in the NPK balance that is listed on fertilizers. Phosphorus is essential to a plant’s growth, but what does it mean if you have high phosphorus in your soil or a phosphorus deficiency?

The easiest way to tell if your garden has a phosphorus deficiency? All you need to do is look at the plants. If your plants are small, are producing little or no flowers, have weak root systems or a bright green or purplish cast, you have a phosphorus deficiency.

Since most plants in the garden are grown for their flowers or fruit, replacing phosphorus in the soil if it is lacking is very important.


When plants don’t have enough of a certain nutrient, pests, disease, and low bearing are often the result. Calcium nitrate fertilizer is the only water-soluble source of calcium available for plants.

What is calcium nitrate? It works both as a fertilizer and for disease control. Diseases like blossom end rot are easy to control with calcium nitrate. 

What does calcium nitrate do? It provides both calcium and nitrogen. It is usually applied as a dissolved solution, allowing for quicker plant uptake but may also be applied as a side or top dressing.


While Nitrogen is of massive importance, Potassium falls right behind.

This is because Potassium has various functions in Palm Trees; however, it is primarily involved in the movement of all essential sugars and nutrients through the plant.

Additionally, Potassium is classified as a micronutrient in plants, as they take up large quantities of it during their lifetimes. It promotes the movement of water, plant carbohydrates, and nutrients between all plant cells.

It also encourages enzyme activation in the plant, which helps form starch, protein, and ATP (energy) which speeds up the rate of photosynthesis.

An ideal supply of Potassium is necessary because it also regulates the opening and closing of plant stomata, which allow the gaseous exchange of oxygen and carbon dioxide.


Moving on we will look at the use of sulfur in fertilizer. Sulfur is an essential macronutrient that has a very crucial role in oil biosynthesis in oilseed crops. Sulfur is generally deficient in oxisols and ultisols and thus needs proper consideration for enhancing the oil yield of oil palm. 

However, sulfur is least considered in soil fertility and nutrient management programs of oil palm plantations. We have reviewed the literature to highlight the role of sulfur in the biosynthesis of oil in oilseed crops in general and oil palm in particular and have suggested some suitable measures for sulfur management of oil palm plantations for enhancing oil yield in highly weathered soils of oxisols and ultisols.

Magnesium is the chief core of chlorophyll, the substance that gives plants their characteristic green color. Therefore, if the chlorophyll supply drops, the Palm Tree’s growth is fairly stunted.

Magnesium also helps activate certain enzyme systems required for the plant’s normal development and metabolism.

In many fertilizers, Magnesium is added in a small quantity because most soils naturally contain adequate amounts. However, soils that are too acidic may need an external Magnesium source.

Approximately, the soils with a pH below 5.5 need relatively high amounts of Magnesium in the fertilizer. The amount of Magnesium is also related to Calcium concentration in plants.

Moreover, many plant experts believe that an ideal ratio of both Magnesium and Calcium is necessary for a plant to grow normally.

The Palm Trees deficient in Magnesium show a wide variety of symptoms, such as yellow or discolored leaves, yellow leaf edges, and yellow or abnormal-looking veins. Some other colors, for instance, brown, red, or purple, may also appear.

Often with older Palm Trees, some as old as decades, show deficiency signs first and fall off. The deficiency then begins to affect the new growth, stripping the foliage of its color and healthy appearance. If treated initially, the damage is reversible.

Therefore, ensure that your palm tree fertilizer has a sufficient amount of magnesium so that it can grow to its fullest potential.


Some crops are much more sensitive to boron deficiency than others. Perennial legume forage crops, including alfalfa, clovers, and birdsfoot trefoil are sensitive to low soil boron.

Adding boron is often recommended for these crops. Brassicas, including certain vegetables (cauliflower, cabbage, broccoli, turnip, rutabaga, kale, and others), canola and forage brassicas like rape and forage turnip are among the crops known to be sensitive to low soil boron levels.

Sugar beets, apples, red beets, celery, and sunflowers are also sensitive to boron deficiency. On soils with low cation exchange capacity, your soil test report may include a boron recommendation for these crops.


Zinc is an essential micronutrient for plant life. In Minnesota, while some soils are capable of supplying adequate amounts for crop production, the addition of zinc fertilizers is needed for others. 

Zinc is a recommended micronutrient in fertilizer programs for the production of corn, sweet corn, and edible beans. Several research projects have focused on the use of this nutrient, and much of the following information is based on the results of that research.

Zinc exists naturally in rocks. The amount of zinc present in the soil depends on the parent materials of that soil. Sandy and highly leached acid soils generally have low plant-available zinc. 

Mineral soils with low soil organic matter also exhibit zinc deficiency. In contrast, soils originating from igneous rocks are higher in zinc. Plants take up zinc as the divalent ionic form (Zn2+) and chelated-zinc.

Finally, cool soil temperatures in early spring can intensify the need for zinc. When the soil temperature is low, mineralization of soil organic matter slows down resulting in less amount of zinc being released in the soil solution. Root growth is also stunted by cool temperatures and reduces the plant’s ability to find new sources of zinc in the soil profile.


Last but not least is copper. Copper is an essential element for plant growth. Soils naturally contain copper in some form or other, ranging anywhere from 2 to 100 parts per million (ppm) and averaging at about 30 ppm.

Most plants contain about 8 to 20 ppm. Without adequate copper, plants will fail to grow properly. Therefore, maintaining fair amounts of copper for the garden is important.

How to Fertilize Palm Trees?

The method of fertilizing palm trees is a technique that you can easily pick up once you understand the fundamentals of what your palm tree needs. When fertilizing palm trees, it’s important to use a slow-release fertilizer, such as Milorganite, which can work for up to 10 weeks, as it provides nutrients over a longer period of time and reduces the risk of leaching.

Quick-release fertilizer, especially in sandy soil, can easily wash away after only a few drops of rain. Milorganite also contains organic matter, which builds healthier soil and holds moisture.

Apply Milorganite four times annually, evenly scheduled throughout the growing season, which could begin as early as March and end as late as October, depending on your location.

Apply 5–10 lbs. of Milorganite by broadcasting it under the entire canopy of the palm. Stay two feet from the trunk of a palm; it’s tender and can be easily scared, or burned when applying quick-release fertilizers.
