Summary

 

The pine regeneration tillage was put in 1996, on after-forestal and industry wear soils, in 1,4 km NE distance from the large emitter. During institution of tillage, at ploughing up furrows, the structural building the ground surface and upper part soil profile was altered to depth of 40cm. The compensatory mineral fertilizations of Ca, Mg, K and P were executed also. The soil samples were taken with five depths to 45cm, in 28 deadlines in the early spring, summer and autumn times, since autumn 1995 till autumn 2004. On the basis of the gathered data, introduced in tab. 1-3 as well as on ryc. 1-6, introduced the profile of research object and laboratory methods, the ecochemical change and state of the rhizosphere layer in soil before the establishment of pine tillage, the ecochemical change in this layer after the establishment of pine tillage with regard to the times of year, the gradients of the easily variables components of soil in rhisosphere. Three developing phases of quantitatively – qualitative dynamics of the easily variables elements in lengthening periods of time were affirmed.
