In our country, potato is a highly important national crop, as a basic food element (almost the population's second bread), while for the Apuseni Mountains area, potato holds the highest percentage and at the same time represents an essential food for locals and their animals, as a paramount food support of the population in the area. Its specific renders this crop as a highly demanding species of plant in terms ecologic conditions, humidity and temperature, as well as nutritive elements, as it forms an abundant vegetative mass and a high tuber quantity for the surface unit. It is a highly consuming nitrogen, potassium, magnesium and calcium plant, as well as with respect to macroelements. Once the potato is harvested, the export of mineral elements from the soil is high, thus determining the rapid soil depletion and demanding for a suitable fertilization of potato crop, adequate to the household system specific to the mountain area. Numerous research conducted in the area under study reveal the fact that, from a pedoclimatic point of view, there are good and very good conditions for potato crop, considering the climatic abnormalities in the last period. But the severity of the climatic impact varies from one region to another and exerts a serious effect on agriculture. In this highly important sector, climate changes would influence crop harvest, animal breeding and location of production. The increased probability and severity of weather events will considerably increase the risk of crop calamities. The climate change will exert an influence on the soil, by decreasing the organic matter content - a major contributor to soil fertility. In this context, considering the basic occupation of locals in the area, especially animal breeding, a large quantity of organic fertilizers is used and by meas of their rational employment, they represent the main fertilization source of crops in the area, recovery and maintenance of soil fertility. Alongside being the basic food product of population in the area, the importance of potato increases once the altitude of the area also increases, being used as fodder for animal husbandry, due to the fact that the assortment of cultivated plants is limited to potato, rye, oat, some fruit trees, certain vegetables, while the rest of the surfaces is covered with natural pastureland and forests. In this respect, potato covers the largest surface, as corn hybrids, even early ones do not manage to reach maturity in this mountain area.
