Crystalline fertilizers - everything you need to know

Nawozy krystaliczne

What are crystalline fertilizers?

Crystalline fertilizers are a group of loose fertilizers, adapted to the creation of water solutions and intended for foliar application, used to provide comprehensive nutrients to the fertilized plants.

Currently, a wide range of this type of fertilizer is available on the Polish market. They successfully replace the more widely used liquid fertilizers, often based to a large extent on nitrogen. When introducing crystalline fertilizers, producers emphasized primarily:

What is the composition of crystalline fertilizers?

Virtually every producer determines the "original" composition of his fertilizer, which is usually a mixture of macro- and microelements with "unique" advantages. With this in mind, first of all, check the product label when choosing a specific fertilizer.

The micronutrients in this type of fertilizers are most often in the form of chelates (except boron and molybdenum), inorganic salts or oxides. In the case of chelate-based fertilizers, the composition should include:

The content of the chelated form should not be less than 80%. The composition of chelate fertilizers may be adapted to the nutritional needs of a given plant or more universal. Chelated fertilizers are characterized by a good absorption of microelements. They often contain only one element in concentration. However, it should be taken into account that the effectiveness of chelates is determined by temperature. The optimal range is 15 to 25 degrees Celsius, so they are not suitable for late fall or early spring treatments.

In the case of salt-based fertilizers, it is important to provide information on the content of micronutrients and their solubility in water. Inorganic salts of micronutrients (nitrates, sulphates, chlorides) dissolve well in water, but are less absorbed by the leaves. Consequently, they require the use of higher doses than chelates in order to achieve a similar effect. However, their action is effective at lower temperatures and is characterized by a higher concentration of ingredients.

The oxide form of the micronutrients is characterized by a high concentration with relatively low solubility. Hence, this group of micronutrients, due to the spread over time, is most often used to supplement the abundance of elements present in the deficiency in the soil.

DR GREEN crystalline fertilizers - a modern solution

A completely new quality in the offer of crystalline fertilizers is the product of the Polish fertilizer brand Dr Green, a relatively recently established but already well-known to farmers. It combines all the factors determining effective and efficient feeding of plants.

This modern technology is based on micronutrient fertilizers - dedicated to specific types of crops - and universal fertilizers: macronutrients. The possibility of using them in various combinations, depending on the current needs and conditions (application date, weather conditions, course of vegetation) has become an effective method of increasing the quality of crops and crop efficiency.

The innovative formula and the pH stabilizer included in the composition combine with such features as:

It can therefore be said that this fertilizer combines and at the same time surpasses all the advantages of its predecessors.
