To Receive

To receive precise results of manure influences on Festuca rubra meadows were studied on to types of soils: Terra rossa and Brown eu – mezobasic rendzina. Manure graduate dosages were established as: V1 - control, V2 - 10 t/ha manure, V3 - 20 t/ha manure, V4 - 30 t/ha manure. Changes on herbal phytocenoses are very close depending to the type of soils. The 20 and 30 t/ha of manure treatment applied increase the installation of the Poacee species in front of the Fabacee species and plant from other botanical families, but the treatment with 10 t/ha of manure maintain the equilibrium of the 3 mention groups because minimal changes are happens.

AbstractThree samples of terra rossa were shown to be efficient adsorbents of phosphate [P(V)] from wastewater and removed 29.9–32.6% of P(V). The total iron content in terra rossa was the key factor which determined the P(V) removal from wastewater. The original samples of terra rossa were effective support materials for the immobilization of metabolically active P(V)-accumulating bacteriaAcinetobacter junii(0.56–2.47×1010CFU g–1). The removal of oxalate-extractable iron from original sample of terra rossa increased the number of immobilized bacteria to 1.34×10–11CFU g–1, which is the largest number of immobilized bacteria reported in the literature so far. In reactors containing theA. juniiand terra rossa P(V) was removed from wastewater by simultaneous adsorption onto terra rossa and accumulation inside bacterial cells, resulting in 40.5–62.5% of P(V) removal. Terra rossa is a promising substrate for biological P(V) removal from wastewater, acting both as adsorbent of P(V) and carrier of P(V)-accumulating bacteria.

Research on weathered crusts on carbonate rock is essential for paleoenvironmental studies in karst areas. Terra rossa, widely distributed in tropical karst areas, has not been studied in terms of its material sources and geochemistry. Two typical terra rossa profiles on dolomite (SC profile located at Sang Cai, Hoa Binh province) and limestone (TG profile located at Tong Gia, Lao Cai province) in Northern Vietnam were selected to examine the geochemical characteristics and the evolutionary processes of rare earth elements (REEs). Chondrite and bedrock normalized patterns indicated that these two profiles are in situ weathering crusts, meaning they are the residual material remaining after chemical weathering of the lower carbonate rocks. The average value of total REE in the SC profile is 381.19 ppm, which is 30 times higher than the bedrock. In the TG profile, the value is 386.26 ppm, 13 times higher than the bedrock. Compared with the profiles in nearby subtropical areas in Southeast China, the REE enrichment coefficients of terra rossa in Northern Vietnam are much higher. The REE depletion was also different between the SC and TG profiles. The light and heavy REE fractionations in the SC profile are higher than in the TG profile. Paleoclimate inversion analysis shows that the SC profile experienced a stable oxidation condition, whereas the TG profile was subjected to several reducing environments since a weathering crust formed.

Abstract The bauxites of southern France--in particular those of upper Var--result from the alteration of lateritic soils formed at the expense of various rocks from crystalline and crystalline-phyllitic massifs (notably the Maures-Esterel of the Brignoles region). The resulting detrital grains are of varied granulometric and mineralogic composition; they have been transported into vast basins formed on surfaces of Jurassic and basal Cretaceous limestone karst into which they were deposited. Various hydrostatic levels in different basins have caused, during the course of diagenesis, modifications in structure and chemical and mineralogic composition (gibbsite, boehmite, and diaspore facies of the bauxites). The intensity of development is related to erosion that has acted mainly in a vertical direction; it has been controlled by subterranean karst drainage. Post-diagenetic effects, such as the mobilization of iron and the formation of terra rossa, have caused the formation of polygenetic soils.
