Cultural practices (intertill
hilling, fertilization, irrigation, and pest control) were carried out on the same day for the same site.
The groundwater reserves recharge is facilitated by high permeability of sediments and hydraulic connections between intertill
aquifers in the paleoincisions, inherited by present river valleys.
Radiocarbon age estimations from several sites near Solova, such as Viitka intertill
organic layer (Fig.
The majority of the [sup.14]C dates obtained from sub- and intertill sequences with organic remains in Estonia (Petruse, Viitka, etc.) are younger than one would expect on the basis of the conventional radiocarbon method (Raukas 1986).
As for the Pleistocene intertill beds very different and contradictionary TL dates were obtained (e.g.
Even more it influences the dating of older intertill deposits where the genesis of sediments and most of the limiting factors are unknown.
deposits of Western Latvia and some peculiarities of their development.
It was, accordingly, assumed that some of these buried palaeoincisions could be of great stratigraphical interest, because as a result of numerous glacier passages many tills and intertill
deposits were developed and preserved in them (ibici).
This amount is larger for intertilled
crops, amounting to 2.7% of the soil humus pool per year for potato; for spring cereals the respective percentage is up to 1.9 .
