Why do you need fertilizers?

The use of fertilizers is crucial for growing uniform and flavorful vegetables. Liquid and solid fertilizers ensure that plants receive the right nutrients throughout their growth. This leads to better growth, stronger plants, and higher yields that meet market standards.

When is the best time to add fertilizers?

It is important to apply fertilizers just before planting, so that the young crops have sufficient nutrients right from the start. During the growing season, additional fertilization is often necessary, especially during periods of rapid growth and fruit set. In a controlled greenhouse environment, you can precisely time liquid fertilizers to align with the growth phases of your specific plants, ensuring optimal uptake. Also, make sure to plan your fertilization after irrigation to prevent leaching.

What are trace elements and what are they used for?

Trace elements, also known as micro-elements, are essential nutrients required in very small amounts for the growth and development of plants. Although they are present in minimal quantities, they play a crucial role in various biological processes. Some important trace elements include:

  1. Manganese (Mn): Involved in photosynthesis, respiration, and the synthesis of certain enzymes. It also helps protect against diseases.
  2. Zinc (Zn): Essential for protein synthesis and the growth of new leaves. A deficiency can lead to stunted growth and leaf discoloration.
  3. Copper (Cu): Important for photosynthesis, nutrient transport, and enzyme function. Insufficient copper can hinder plant growth.
  4. Boron (B): Plays a role in cell wall structure, flower and fruit development, and sugar transport. A deficiency can lead to poor fruit development.


Although trace elements are needed in small quantities, they are indispensable for the health and productivity of plants. A deficiency in these nutrients can result in various growth problems and reduced yields. Therefore, when fertilizing crops, such as in horticulture or vegetable cultivation, it is important to pay attention to the proper balance of trace elements.
