Abstract. The goal of this paper is to present the main hydric features of the cambic chernozem in Timisoara, Romania, i.e. hygroscopicity coefficient, field capacity, total water capacity, and useful water capacity. (4,9) The objectives aimed at are characterising the studied area from the perspective of its natural conditions, studying the main soil hydric features, describing and determining the main hydric features of the cambic chernozem at the Didactic Station in Timisoara, Romania – hygroscopicity coefficient, field capacity, total water capacity and useful water capacity, and diversifying and specialising soil research and studies in the field. Soil was sampled in five replicates from 0-20 cm deep in the soil, in three different points: (310) Sample 1 – Ploughed soil; Sample 2 – Ploughed soil + disked and Sample 3 – Uncultivated soil covered by grassy vegetation. Soil sampling was done in two years,2017 and 2018, in April, before sowing maize, in samples 1 and 2 on cultivated land. In general, moisture excess – ground or stagnant – is the amount of water making the soil improper for working or cultivating, it is water above or below the level necessary for plants to grow. Moisture excess is a limiting factor of soil productivity; it damages crops determining a decrease of agricultural production. Sometimes, soil excess water can totally compromise the crop by impeding or even interrupting vegetation; this is why we made measurements of soil water supply.(7,8)
