Scientific Papers, USAMV Bucharest, Series A, Vol. LII, 2009, ISSN 1222-5339ASPECTS CONCERNING MORPHOLOGICAL, CHEMICAL, PHYSICALAND AGROPRODUCTIVE CHARACTERIZATION OF THE GLEYICSOLONETZ FROM VIZIRU PLANEROXANA CLUCERESCU*, NICOLETA BALABAN**, M. MIHALACHE**University of Agronomic Sciences and Veterinary Medicine of Bucharest**Pedological and Agrochemical Testing Office of BucharestKeywords: plain, soils, gleyic solonetzAbstractSituated in the Southern extremity of the Romanian Plane, Viziru Plane presentsa relative large soils scale, unified in Cernisoils and Salsodisoils classes. FromSalsodisoils class are found gleyic solonetz that occupies relative small areas(900 ha) and appears locally in Northern part of the plane, which corresponds tosome microdeppresions area imperfect drained.54
Scientific Papers, USAMV Bucharest, Series A, Vol. LII, 2009, ISSN 1222-5339MODIFICATION OF SOME INDICATORS OF THE PRODUCTIONPOTENTIAL IN PLUM, UNDER THE INFLUENCE OF EDAPHICCONDITIONS SPECIFIC TO SATURATED SOILSC. LAZĂR*, DANIELA RĂDUCU*, DANIELA DANA*, Z. JAKAB**,RODICA LAZĂR**National Research and Development Institute for Soil Science, Agrochemistry andEnvironmental Protection of Bucharest**Rootstock Breeding Department, Fruit Research and Development Station of BistritaKeywords: plum, calcium carbonate, saturated soilsAbstractThe favorability evaluation of a field for the fruit growing culture is performed taking intoaccount not only the climatic conditions of the field and the soil conditions. For theindustrial cultivation of fruit species on saturated soils, the factor which conditions theproduction potential can be ordered into four groups: soil carbonates and the phytotoxicityof calcium, the aero-hydrical regime, the probability of the appearance ofsecondary compacting and the risk of the starting of calcic chlorosis. The research led tothe identification of limiting factors specific to saturated soils, and distinguished the factthat the nutritional unbalances induced by the presence of these in the soil, do not manifestjust at the roots level through the modification of the root system distribution and theappearance of dead roots but also at the upper part of the trees through the decrease oftrunk thickness growing, a steady indicator of the production potential.58
