Maximizing the positive impacts of irrigation and its influence on the settlement of soil particles.

Researches presented, are the subject of study on the evolution of soil quality indicators of Romanian Plain, where mainly is chernozem soil type, as a consequence of irrigation. To achieve the objectives we have studied some physical indicators of soil  ( bulk density and total porosity ) A®n the territory concerned, the interpretation of analytical results been performed according to the proper methodology, after taking soil samplings from pedogenetic horizons. Through an analysis of the evolution of chernozem’s soil compaction, due to irrigation’s application, it highlights different soil compaction status correlated with the physical condition of the soil. If irrigated soil, in maize crop, loosening is moderate A®n the layer 0-10 cm, with values of 1.20 g/cm3,after applying every year of irrigation, it indicates values ranging A®n a fairly widely, from small  (moderately loose soil, with bulk density of 1.23 g/cm3) , the medium  ( soil poorly compacted, bulk density was 1.45 g/cm3) . Total porosity values are down slightly throughout the soil profile under the influence of irrigation, values are A®n the range middle - very high. After applying irrigation are observed physical changes, that induced changes in the balances resulting from damage to structure and structure to appear grainy dust structure and consequently the tendency of poor compaction and physical change of the soil.
