- Abstract
Agriculture has a major contribution to the sustainable rural development and to the development of the economy of a country, thanks to the implementation of some agricultural technological systems which helps: to rise the organic matter content in soil, to reduce the negative impact of soil degradation processes and especially to increase and maintain the fertility of the soil.The experimental design was realized under conditions similar to those used for obtaining the best potato crop specific in a mountainous region, Avram Iancu village being located at an altitude between 800 -1100 m. In 2012-2013, the experiment was bi-factorial started, with Ostara variety, cultivated by the subdivided parcels method. Soil samples were physico-chemical analyzed considering the ICPA methodology of agrochemical laboratories (ICPA, 1980, 1981). The analysis of the main agrochemical factors of districambosoil cultivated with potatoes in Avram Iancu village, highlights the acid and the strong acid character (pHH2O 4,75-5,86), with a moderat humus content. The organo-mineral fertilization causes significant modifications to the agrochemical factors, favorizing a substatial growth of the mobile forms of the phosphorus and potasium. Bioavailability of the nutrients is assured by this type of fertilization creating good conditions for the soi land also preventing the posibble negatice changes due to the acidity and the nutrient losses encountered during the fertilization process. The assesed results,can give proper recommendation regarding these applied agricultural techniques in mountain area, by implementing and promoting organo-mineral fertilisation systems. This type of fertilization is considered efficient and protective for soil and also for potatoes crop.
