Tea cultivation requires “fertilizers.” They can make the tea’s aroma and flavor of your choice if used appropriately.

Fertilizers used for tea

The purpose of using fertilizers for tea is to harvest a lot of tea leaves of high quality. Necessary nutrients are given for this purpose. The main components of fertilization are Nitrogen (N), Phosphoric acid (P), and Potassium (K). There are called “three main macronutrients”. Tea leaves contain a lot of amino acids, so nitrogen supply is particularly important.

Fertilizers can be divided into two major types: “chemical fertilizers” and “organic fertilizers.” Let us take a look at each of them to see their features.

Chemical fertilizers

A chemical fertilizer is a condensed fertilizer produced by chemically manipulating components necessary for the growth of plants. Nitrogen fertilizers, phosphate fertilizers, and potash fertilizers are “straight fertilizers,” which are made of a single kind of macronutrients. Fertilizers made by mixing them are “compound fertilizers.”

Organic fertilizers

An organic fertilizer is a fertilizer made from organic things such as animal dung and food debris. Plant-derived fertilizers use rapeseed meal, soymeal, etc. Animal-derived fertilizers use fish lees, fish meal, etc. Also, fermented fertilizers are produced by fermenting these materials with microbes.

Advantages and disadvantages of using fertilizers

The next topic is the advantages and disadvantages of chemical fertilizers and organic fertilizers.

Advantages of chemical fertilizers

Every fertilizer is different in components. It should be chosen according to the desired action. It is easy to control this type of fertilizers because the types and amount of fertilizers can be adjusted up to the growth of plants. In particular, Nitrogen determines the umami components of tea. You can control the umami of tea by the amount of nitrogen fertilizers.

Disadvantages of chemical fertilizers

Tea trees can absorb the limited amount of fertilizer nutrients. Excessive fertilization causes tea trees malabsorption, which reduces yields and degrades quality. There are also concerns about environmental impact by chemically synthesized fertilizers.

Advantages of organic fertilizers

They contain a lot of organic components and activate the action of microbes in the soil as nutrient sources. Products by the microbes enhance the quality of the soil, and the tea trees grow well. Additionally, fertilizers made from organic materials such as food are eco-friendly and also good for the human body.

Disadvantages of organic fertilizers

They act slowly compared with chemical fertilizers, so it is hard to tell the timing of fertilization. Wrong fertilization control can inhibit the crop growth and reduce yields. It is necessary to control fertilizers by constantly checking the conditions of the soil, weather, and growth.
