SOIL DENSITY IS A FUNCTIONAL - GENETIC ASPECT
Journal Title: Present Environment and Sustainable Development - Year 2007, Vol 1, Issue 1
Abstract
La monitorisation de la densité des sols spécifiques pour trois périodes, bien sur différentes pour chaque cycle annuel dans la densité et l`orientation des processus pédogénétiques. Les plus favorables conditions pour l`évolution des processus de tchernoziom sont crée pendant le printemps et au début de l`été ( Avril juin) ; l`humidité du sol est proche de la plus basse valeur en capacité d`humectation et les densités des sols sont 1,1-1,3 g/cm3 .Pendant cette période la porosité totale a des valeurs de 55-56% et la porosité de l`aération est de 20-25% Cette periode est caractérisée par la plus grande activité des processus biologiques avec les processus chimiques et physico-chimiques.
