Abstract:
Agricultural land quality and productivity assessment relies both on soil fertility, which is undoubtedly the most
important factor, and on climate, relief and hydrology factors. Soil quality is affected to a higher or lesser extent by one
or more restrictions determined either by natural factors, or by agricultural and industrial anthropogenic actions, which
may have a negative synergistic influence, the effect of which is a decrease in soil quality and even the abolition of its
functions. This paper tackles the soil mapping surveys and the climate, relief and hydrology conditions in the Ion
Neculce administrative-territorial unit, Iaşi County. From the climate point of view, the surveyed unit belongs to the
temperate climate, with an average annual temperature of 9.5
oC and average annual precipitations of 502 mm, which
fall unevenly. The relief is mostly hilly, the biggest area of 6108 ha is located at altitudes ranging between 100 and 200
m, whereas 114 ha at altitudes ranging between 200 and 300 m. The water system is relatively dense and belongs to the
Bahluieţ river basin, a characteristic being the intermittent watercourses and the presence of temporary ponds in the
depression areas. The productive capacity of the soil on the mapped area of 6338 ha is affected by surface erosion
(53.35%), landslide (27.74%), gullies (1.12%), gleying (14.11%), stagnogleying (0.56%) and salinization and
alkalization up to 26.25% of the surveyed area. The Ion Neculce Commune soils belong to the Cernisoils (69.45%),
Antrisoils (14.04%), Protisoils (9.91%), Luvisoils (3.40%), Hydrisoils (1.92%) and Salsodisoils (1.28%) classes.
