"In practical-economic activity, the Laboratory of Functional Leaf Diagnostics "Agrovector" PF-014 "serves as an effective mechanism for agro-chemical audit of crop cultivation. This technique relates to qualitative methods of analysis and perfectly complements the basic quantitative methods of agrochemical research. Identifying the lack of fertilizer elements allows you immediately to adjust plant nutrition by vegetation, or establish factors that affect the digestibility of nutrients from the soil."

"The device "Agrovector PF-014" was used during the growing season of 2012 in the laboratory of soil and plant diagnostics at the Podillya Institute of Forage and Agriculture of the NAAS. Fields of winter wheat, rapeseed, soya and white beets were examined in critical phases of plant development. According to the figures of the device it was obtained the data on the lack of basic microelements of plant nutrition and it was adjusted the rates of fertilizer element for feeding under the abovementioned crops. On the surveyed areas it was received results that well reflect the state of growth and development of plants in critical periods, their need for individual elements of nutrition. "

"Laboratory of functional diagnostics of plants "Agrovector PF-014" ensures fast and qualitative carrying out of necessary measurements. The laboratory itself is easy to operate. The advantage of the Laboratory of Functional Diagnostics "Agrovector PF-014" is that it provides long-term atomic work in the field without an external power supply, a simple and easy-to-use menu, and an automatic analysis of the needs of minerals. The software provides a comprehensive assessment of the nutrient input and, taking into account the data of agrochemical soil analysis, to form a fertilizer system. My practical activity with the use of the functional diagnostic laboratory "Agrovector PF-014" was associated with the measurement of predominantly perennial fruit and berry crops. Compared to annual crops, perennial fruit and small-fruit crops during the growing season not only form the crop of the current year, but also lay the foundations for the formation of the next year's harvest. Timely correction of mineral nutrition by the results of functional diagnostics can not only regulate the receipt of fertilizer elements, but also improve the quality of products. This is especially important on soils with high content of carbonates, washed and light mechanical composition, in adverse weather conditions (prolonged rain and cold periods, heat), wrong or excessive use of pesticides. In practice, the use of the laboratory of functional diagnosis "Agrovector PF-014" fully justifies itself, first of all, with the high quality of the obtained plant products."
