What is Fertigation?

Fertilizing through an irrigation system is referred to as «fertigation.»
Fertigation consists of applying simultaneously water and fertilizers through the irrigation system, supplying the nutrients required by the crops to the soil or substrate. Fertigation is especially useful in the case of drip irrigation. By means of automatic high technology fertigation equipment the water and the nutrients are perfectly placed in the absorption area of the roots, improving the rate of growth and quality of the crops. So this system allows carrying out a more rational use of the water and fertilizers, respecting the environment and minimizing the environmental impact. If you’re running a greenhouse, you’re used to controlling every drop of water. But precision fertigation goes further by sending a precise mix of water and nutrient solutions.

Automatic fertigation control systems

When it comes to automation, all irrigation systems test the soil moisture level and manage nutrient dosing. Some systems integrate with facilities existing environment control unit to manage from a central location. Automated fertigation control system monitors a range of factors across the system. A filtration system cleans the water with UV light, pasteurization, and filtering. Then sensors measure the level of the water in the tank, temperature, and Ph levels. Sensors in the mixing tank measure the EC nutrient level and pH, adding acid or base as needed. Soil sensors measure moisture and over drainage to relay to the nutrient dosing equipment. Pump controls and irrigation valves connect to the control system to be managed automatically.

The thermal disinfector is specially designed for greenhouse complexes. Thermal sterilization is the most effective way of drainage cleaning. The principle of the disinfector is to heat the drainage water to temperature of 85-95 ˚C and hold it at this temperature for up to 180 seconds, and then the drainage is cooled to temperature close to the original heating the incoming water. Such a long high-temperature treatment allows 99,8% of harmful bacteria, fungi and viruses’ destruction.
Usually heating of drainage water is implemented with the help of greenhouse heating systems, which makes the whole process of disinfection quite economical. In case required water temperature lacks of the heat transfer unit, the disinfector is equipped with its own electric heater, which can work as in parallel with the heat network providing only required temperature addition and separately taking the entire heating process by itself. Acid is automatically added to drainage water for prevention against destruction of solutions’ structure and also to avoid calcification inside the disinfector. All parameters of the technological process are controlled by means of PC.
The advantageous systems’ difference from imported analogues is concluded in the intellectual controlling function of the drainage water consumption. This function allows you to realize the fact that drainage disinfection saves for 3 minutes at 85 ˚C, but at 95 ˚C only for 90 seconds. Therefore, when disinfections’ temperature for various reasons exceeds a minimum of 85 ˚C the system automatically increases drainage water consumption thereby accelerating saving process. In addition, the system determines independently temperature of heating medium and if it is necessary, turns on its own electric boiler.
The one of the functionality is also possibility of automatic work with drainage storage tanks, i.e. the system is automatically turned on and off depending on the water level in the tanks. The computer calculates daily the system’s operating time and the amount of disinfected drainage per day and also for the entire operation time. This data is stored for 10 days in the controller memory, as well as transferred to a PC for unlimited storage and available for viewing. Controllers of our company can be combined into network (up to 12 controllers) and connected to PC. At the same time PC can specify the disinfection programs and the disinfection process can be controlled in detail. Reports and archives can be printed too.

Today the disinfection by means of ultraviolet irradiation is widespread in the world along with the thermal disinfection. The advantage of this method is low energy intensity. The operation principle is to pass UV radiation produced by special lamps through water. UV radiation with wavelength with bactericidal effect (253,7 nm) penetrates through the cell walls of microorganisms carried by water and is absorbed by DNA in the genetic chain. As a result, the process of microorganism production ceases. The sterilization unit is designed specifically for disinfection of drainage irrigation water. It is equipped with low-pressure lamps from a German company UV-Technik as the most economical and constructively convenient lamps for using precisely in greenhouse complexes. Functionality allows agronomist to set the dose of irradiation solution in the range of 50 mJ/cm2 (selective disinfection e.g. for salad complexes) to 250 mJ/cm2 (complete disinfection). During operation process the UV-lamp capacity is measured by a sensor mounted on the external surface of the disinfection unit. On the basis of this data the computer system automatically calculates time it takes to obtain a given dose of UV- radiation and adjusts system capacity.
As known, the determining factor of the system capacity is transparency of drainage solution. It is recommended to install a sand-gravel filter for cleaning of the drainage from mechanical and organic impurities at the disinfector outlet. The possibilities of the disinfector also allow to control the process of filtration with automatic rinsing of disinfector, and if it necessary, mixing process. On the irrigation unit is installed an acid dispenser which ensures an increase of the solution acidity to avoid contamination of the lamp.
The function of intellectual control realized in the presented UV-disinfector distinguishes it from foreign analogs, namely, it is the change in disinfection capacity depending on drainage transparency.
It is important, that all controllers can be connected to the «MONITOR» program, which allows you to monitor all equipment and make the necessary adjustments depending on technological requirements.
