title: [Effect of physico-chemical factors of the soil on the Oribatid population].
abstract: Orbatid populations present in the ground of four randomly selected patches of land for calf farming underwent ecology during four months. The statistical analysis of results disclosed a highly significative decrease of the population in one out of such patches of land. The physicochemical analysis of earth samples from each patch of land permitted the explanation for the phenomenon on the basis of an increased calcium concentration in the least populated patch of land.
