Everybody loves a good cup of coffee to kick-start their morning. But have you ever wondered what nutritional boost goes into coffee plants to give you exquisite coffee beans? Coffee is a perennial crop, simply meaning that it requires proper nutrition around the year. Apt nutrition is required to perform two main functions: producing fresh cropping wood framework and maturing the crop.

Over time, the soil starts to lose these essential nutrients, which can be fulfilled by the application of correct fertilizers. In this article, we will discuss the type of fertilizers required for better health and yield of coffee plantations.

Understanding the Nutrient Requirement of Coffee

Along with basic elements like carbon dioxide and water, coffee requires the following nutrients in appropriate amounts to ensure well-rounded development.

  • NPK: Nitrogen, phosphorus, and potassium are categorized under the macronutrient head. The reason is that coffee plants need them in large quantities. 
  • Medium nutrients: As the name suggests, coffee plantations need nutrients like sulfur, magnesium, and calcium in lesser quantities as compared to NPK.
  • Trace elements: Although required in very small amounts, elements like boron, manganese, iron, copper, chlorine, and molybdenum are vital for plant growth. 

What Fertilizers Are Required in a Coffee Plantation?

Fertilizers provide readily available nutrients to plants. When it comes to coffee plants, they require the following fertilizers.

Nitrogen

It is regarded as one of the most essential nutrients required for coffee production. Plants uptake nitrogen from soil in the form of NO3- and NH4+. It is interesting to note that coffee plantations with shade require less amount of nitrogen as compared to plantations with direct sunlight. 

The best time to apply nitrogen-based fertilizer, i.e., urea and ammonium nitrates, is during the rainy season when the fruit, new leaves, and branches grow. The reason is that if there is not enough nitrogen, then the plant will focus only on fruit production, and the growth of the plant can hamper the next year’s yield. 

Phosphorus

Phosphorus is another important macronutrient that coffee plantations need. But when compared to nitrogen, phosphorus is relatively immobile in the soil. It means irrespective of how much of this fertilizer you add to the soil, it won’t make a difference unless it is close to the roots. 

You can see phosphorus deficiency in coffee plants post-harvest. The application of potassium phosphate compounds can correct this deficiency. Consider application 2-20 days apart for quick treatment of the symptom. Also, be wary of excess application as it can inhibit a plant’s ability to absorb other required nutrients. 

Potassium

Third, among the trifecta of macronutrients, potassium is also important for increasing the total coffee yield. An adequate amount of potassium ensures a high-quality fruit that has a direct bearing on the taste, shape, and color of beans. 

To know if your coffee plantations are deficient in this nutrient, you can look at the old leaves of the branch. The edges of the leaf are usually brown, and over time, they can fall off. Moreover, it can also impact the fruit as well. 

Not only that, but the application of potassium also ensures the plant’s ability to absorb water and increase tolerance to cold and salts. 

Fertilizers Required for Medium and Trace Nutrients

Both the medium and trace nutrients play crucial roles when it comes to maintaining proper plant functions. Deficiency of such nutrients can be fulfilled via foliar application or broadcasting. Old coffee soils are prone to having less quantities of micronutrients. 

Boron

It helps promote the growth of shoots and also helps attain maximum fruit and flower arrangement. Moreover, this fertilizer also helps in the plant’s resistance to diseases and proper formation of cell walls.

Zinc

This fertilizer helps accelerate the initiation and formation of flowers and also has a bearing on the leaves. Both zinc and boron are vital for better yield and, in deficient soils, should be applied twice a year. 

Sulfur

Sulfur is an important fertilizer when it comes to the formation of chloride, which is responsible for the photosynthesis process. Not only does it regulate the formation of chlorophyll, but it also plays a crucial role in activating and stabilizing various enzymes within the coffee plant.

How to Apply Fertilizers to Coffee Plantations

To get optimal results, you have to follow some steps for the proper application of fertilizers in a coffee plant. The steps are explained below.

Step 1: Soil Testing

Before you plan on applying any fertilizers, it is essential for you to conduct a comprehensive soil test. The purpose of conducting such a test is to identify the present nutrient levels, pH, and soil texture. Once you have the results in your hand and you observe that there is a requirement for a specific nutrient to achieve the desired plant growth, you must go to the next step.

Step 2: Fertilizer

Now that you are aware of the deficient nutrient, proceed with the appropriate fertilizer. However, remember that you have to have a balanced ratio between the essential nutrients. You can either get an organic or inorganic fertilizer. The choice depends totally on your plant and soil requirements. 

Step 3: Application Method

Various methods can be used to apply the coffee plant fertilizer. To name some, there is a broadcast method, band application method, foliar application method, drip irrigation method, etc. 

You must apply these fertilizers during the active growth phases of the coffee plant, typically during the rainy season, because the plants are more receptive during that time. Make sure to apply the fertilizer in multiple shifts throughout the year rather than going for it in one go to avoid nutrient leaching. 

Parting Words

If the plant is left untreated and no care is given to it, there is a chance that it might die. Therefore, it is your responsibility to regularly monitor the plant’s growth and its response to the fertilizer application. You have to pay close attention to signs of improvement and check if there is any need for adjustment in the quantity of fertilizer used.
