Fertigation as a way to fertilize with Valley Pivot Systems

The possibility of applying fertilizers at the same time as the irrigation water in the pivot systems ensures optimal irrigation and fertilization, saving water, fertilizers and labor and fuel costs. The precision in supplying the irrigation rate through the Valley systems leads to greater accuracy in the application of fertilizers, determining when, over which area and in what concentration to apply a particular fertilizer, depending on the soil and the phase of culture development.Both liquid and solid fertilizers can be used for fertigation, with liquid fertilizers directly imported from the cake tank and solid ones requiring prior dissolution in water.The cake tank is positioned at the pivot center under a stationary system or placed on the frame at the movable linear. Dosing of the required amount of fertilizer into the irrigation system occurs by injection pumps, adjusting their flow rate and pressure, and thus a lot we can easily and quickly dose the substance concentration needed at a given time. The distribution is over the entire area covered by the irrigation system, with which it is achieved uniformityand there is no possibility of overlapping areas. This ensures a level playing field for each plant in the area under consideration and a reduction in the cost of applying an excess amount of fertilizer or the harm from insufficient fertilization. Plants extract the necessary elements and feed from the soil with the top 50% of their root system. Therefore, it is extremely important that the fertilizers that are fed reach this depth in order to be absorbed by the plants. It is with the combination of simultaneous irrigation and fertilization through the pivot systems that moistening of this layer of the root system and penetration of cake into this depth is achieved.With the conventional method of spreading fertilizers, farmers, choosing when to make fertilization, must also take into account the precipitation forecast, but often, when fertilization is required, precipitation is absent, leaving their absorption unrealized. Through fertigation, farmers become independent from drought and adverse climatic conditions, and fertilizers reach the required depth along with irrigation water.With the help of soil and foliar analyses, a balanced fertilization and irrigation plan can be drawn up to implement with the pivot systems, providing the plants with the necessary nutrients and increasing the yield through reduced water, fertilizer, labor and energy resources.Learn more about Valley irrigation systems from the NIK representative closest to you.
