With the current competition in the food producers’ market, the priority is not only to achieve high yields, but also to provide attractive fruit and vegetables for consumers.

Success in plant production is the result of many factors: from the quality of the substrate, through the course of the weather, to the pressure of pests and diseases. While most of them are independent of the efforts of the cultivation technologist, thanks to Florahumus we can provide optimal conditions for the development of plants and their root system.

Fertilization mineral or organic?

In order to increase the yield and quality of the produced fruit, organic fertilization is often used in parallel to traditional mineral fertilization. Due to the availability and ease of use, the use of Florahumus has been adopted as an effective method of organic, complementary to mineral fertilization.

Humic Acids in greenhouse cultivation

According to current research, substances contained in humic acids can affect plants both directly and indirectly. Indirectly, because they affect the growth of plants by improving the parameters of the substrate (including oxygenation, water-holding capacity, mineralization of organic compounds, as well as the availability of macro and micronutrients.) They directly affect the processes related to the uptake and transport of humic substances inside plant tissues.

Effect of humic acids on tomato growth

On the basis of the conducted research and laboratory analyzes, it was found that the nutrient uptake of tomato plants improved in commercial greenhouse cultivation. This was evident in the case of both macronutrients and micronutrients in the examined plant tissues.

The effects of humic acids, directly observed on crops, are:

Faster growth rate

Faster flowering and fruit setting rate

Less susceptible to stress

In addition, the plants watered with Florahumus showed a lower susceptibility to physiological diseases (eg tomato fruit dry rot) and diseases caused by fungal pathogens and pests.

The effectiveness of humic acids is confirmed by research

Research on the effect of Florahumus was conducted on a production plantation. After the application of Florahumus in greenhouse cultivation of various tomato cultivars, a series of laboratory analyzes were performed. The following conclusions can be drawn from the research performed:

Young fruits and fruit sets (0.5 cm in size)

They are most vulnerable to a deficiency of macro and micronutrients because they are in the period of their most rapid growth. In the case of plants watered with Florahumus, an increased content of sulfur, phosphorus, potassium, magnesium and chloride was found. In the case of micronutrients, an increase in the content of most of them, with the exception of iron, was noted.

Young leaf (most photosynthetically active)

After the application of Florahumus, a higher content of phosphorus and magnesium was found. There was also higher content of boron, zinc and copper.

Ripe / harvest fruit

Higher content of phosphorus and potassium was noted in relation to fruit on control plants.


During the FLORAHUMUS tests, changes in the content of the following elements in the tested plants were found in the cultivation of greenhouse tomato:

Potassium (K)

Chlorine (Cl)

Phosphorus (P)

Magnesium (Mg)

Zinc (Zn)

Sulfur (S)

Manganese (Mn)

Bor (B)

Copper (Cl)

Molybene (Mo)


Humic acids and the roots

The substrate in which the root system develops is where Florahumus is taken up by plants.
The influence of the humic acids contained in Florahumus can be divided into two main lines of action:

The impact on the entire root system, visible as changes in the architecture of the root system, i.e. fragmentation of the root bundles, increased branching of the root system.

This effect is visible not only in the root mesh, but also in the analyzes of samples taken from the substrate.

Morphological changes in the root, tl. The number, size and type of root cells, increasing side and hairline branches.

These changes are visible at the microscopic level and practically after changes in the composition of the drainage (filtrate) from the substrate.

[left picture] The root system is not very developed, with a small amount of fine roots. There may be a problem with the water supply and the necessary minerals. Some of the tips turned brown.

[right image] The root system is made of many small roots with an elongation zone. This is a key zone for nutrient uptake. The mat is overgrown in its entirety. Root system fine, white, actively harvesting.

Dosing and dosing methods

It is best when the person responsible for production (cultivation technologist) decides on the method of dosing and frequency, after consultation with the company’s representative (Florahumus supplier).

To ensure the collection of humic compounds, the watering time should be selected so that the plant can absorb Florahumus. Preferably with the first watering cycle and delayed subsequent watering (the delay is to absorb the dose of the preparation by the root system without the risk of an overflow with the next watering cycle).

The dosing methods described below apply to greenhouse facilities (example tomato cultivation). The use of Florahumus should be discontinued 2 weeks before the plant is planted.

Irrigation system [application to the fertilizer tank)

In the case of a fertilizer tank with a capacity of 1000 liters, we use 5 liters of Florahumus poured directly into the fertilizer mixture in the tank. Avoid a reservoir with a high content of sulphates (recommended with calcium nitrate). Continuous use (with each subsequent mixing of fertilizers, we use 5 liters of Florahumus per 1,000 liter fertilizer tank) or alternately (a week of using the preparation and a week without adding the preparation). Application depending on the root system and fruit load of plants. Most often, 1 to 2 times a week [usually every 3 or 5 days).

Irrigation system [application directly to the mixer)

In the interventional administration of Florahumus [for a specific watering cycle or greenhouse valve), we use 0.5 liters of Florahumus for the first watering cycle [with a volume of 100-150 ml per capillary).

Ejector [mounted behind the solenoid valve)

It enables administration to a selected area of a greenhouse, together with a single watering dose [usually it is a dose of 150 ml per capillary, allowing for the administration of 0.5 liters of Florahumus dissolved in 4 liters of water). In practice, it is most often a bucket with the diluted Florahumus preparation in the amount of 0.51 of the preparation in 4 liters of water. From the computer operating the irrigation system, we activate the valve, which by means of the ejector introduces the preparation into the irrigation system along with the watering cycle on a given fragment of the greenhouse [operated by a given valve).

Dosage for cucumbers

The dosing frequency for cucumber is the same as for tomato crops. The dose is increased by 20% due to faster biomass growth. We stop dosing Florahumus one month before the end of production.

In the case of home gardens, the recommended dose is 10 ml per 10-liter watering can.

The frequency of application depends on the needs of the plants. The minimum amount is once every 2 weeks, the volume selected so as to ensure that the Florahumus solution reaches the root system of the watered plants. The frequency of watering may be increased to 2 waterings per week.

How to dose humic acids?

In each case, avoid overflow too quickly for the plant to have time to take the preparation. Therefore, Florahumus is best used at the beginning of the day, when the plant begins to take up water. It is recommended to delay the next watering to give the “thirsty” plant time to take the preparation by the root system and to prevent it from being washed out of the substrate with the next watering.

If we want to extend the application in time and ensure constant access of the plant to Florahumus, then we add it to the fertilizer tank (avoiding sulphates). Then, with each watering, we deliver a constant dose of the preparation to the plant. When we want to give intervention, in a single watering dose, in this case we can choose an ejector (on a specific valve) or a mixer (on a water system). The choice of serving method depends on the facility equipment and the gardener’s preferences.

We use Florahumus at the beginning of plant development to support its growth and fruiting by facilitating the uptake of nutrients from the substrate. In greenhouse production, this will be the rooting period (the initial stage of overgrowing the substrate with the root system coming out of the cube). The second moment of increased demand for nutrients is the period of maximum fruit load of the plant just before the first harvest (the time of coloring the first bunch).

The minimum dose of Florahumus 1 Liter / ha per week is independent of the dosing method. Determining what amount of the product should be used depends on the surface area of ​​one valve.

In the case of fertilizer tanks, we have to take into account when and what surface we water.
If we use Florahumus via a dosing system, 20% overflows should be taken into account.

Following these comments, it will be easier to determine the doses in individual facilities.
