Abstract

The aim of introducing precise fertilization has streamlined the application of fertilizers. Using precision farming reduces costs and increases the efficiency of fertilization. Using GIS technology enables the dispensing certain amount of fertilizer that is really needed on a specific part of the production area. Precise fertilizing is the modern technique of fertilization exactly where soil samples to determine the required amount of fertilizer for a particular piece of agricultural land. Taking soil samples is conducted with probe „Nietfeld Duoprob“. Before sampling it's necessary to gain insight into the conductivity of the soil. Condition conductivity of the soil is achieved by using a scanner „SOIL EC VERIS“ , the obtained data are entered in the advanced agriculutre navigators. During two years of research were used two sampling methods: random and digital. The digital method of sampling used the "Z scheme" and sampled 324 GPS points, while when using random methods sampled 252 GPS points. Using the method of "Z Scheme", has better accuracy in the preparation of maps for fertilizer recommendations and better coverage area. Precision application of fertilizer is the target application of relatively new methods in the Republic of Croatia is fully realized. Preserving the environment is also made possible using the rational use of fertilizers and special techniques of distribution. Using navigation devices and using maps of fertilization was significantly improved exploitation effects. Navigation devices and fertilization maps save time and product materials, and the works can be accomplished at night.
