Abstract

The zone-specific application of inputs such as seed, fertilizer or crop protection chemicals has the potential to maximize yields,  reduce input costs and minimize detrimental environmental impacts. In this paper, the variables of soil electrical conductivity (EC) data in an about 9 ha field were firstly analyzed, and then spatial distribution maps were constructed at ARDS Simnic Craiova. Statistical analyses indicated significant differences between the EC properties of soil samples . The results reveal that optimal number  of sole-specific management zones for the study area was thee. The management zone 1 presented the highest potential crap productivity, management zone 2 the medium, whereas management zone 3 the lowest. We concluded that using EC variables to delimate management zones and mapping of soil EC from an objective basis for development of "zone-specific" application strategies.
