Chemical and microbiological properties of an eutrophic oxisol under riparian Forest buffer reforestation and pasture. Repositório Alice
PULITANO, F. M.; CIPRIANI, H. N.; DIAS, L. E.; DURIGAN, G..
This study tested the hypothesis that, in the course of time, reforestation by means of agroforestry improved soil microbial and chemical properties in a riparian forest buffer. Este estudo testou a hipótese: com o tempo, a recomposição de mata ciliar por meio de agrofloresta melhorou propriedades microbiológicas e químicas do solo.

Growth, Biomass and Carbon Stocks in Forest Cover Planted in an Area of Bauxite Mining in Rehabilitation Rev. Bras. Ciênc. Solo
Valente,Fernanda Daniele de Almeida; Castro,Marllon Fialho de; Torres,Carlos Moreira Miquelino Eleto; Neves,Júlio César Lima; Silva,Ivo Ribeiro; Oliveira,Teógenes Senna.
ABSTRACT Forest cover in areas degraded by mining is an alternative way of mitigating CO2 concentrations in the atmosphere by fixing C in tree biomass. This study evaluated the growth and C stocks of forest cover in an area of bauxite mining with four sources of fertilizer. Height (Ht), diameter at ground level (DGL), and diameter at breast height (DBH) were determined in Anadenanthera peregrina (Ap), clonal Eucalyptus (Euc), and a mixed plantation of 16 native forest species (Nat) at 6, 18, 36, and 56 months of age. Trunk+bark volume, biomass, and C stock were also determined for these forest covers at 56 months of age. The fertilization treatments were a standard (SF) adopted by the company, SF plus organic fertilizer (OF), chemical fertilizer (CF), and...

How old maps are used to investigate modern environmental issues in the Czech Republic Naturalis
Cernajsek, T.; Hauser, C.; Posmourny, K..
The Austrian Geological Survey and Czech geological organizations have in their archives source materials that can be used for the landscape restoration. At many places in the Czech Republic, considerable changes of the environment took place due to building and other industrial activities, especially the mining of mineral raw materials. Changes of relief, river networks and hydrogeological conditions are conspicuous. The largest changes and damages are due to open-cast mining in the North Bohemian and Sokolov brown-coal basins. Other damage was caused by underground black coal-mining, exploitation of uranium and building materials. During huge floods in northern and central Moravia in July 1997, the morphology of the landscape underwent conspicuous...

Institutional perspectives of land reclamation operations in Punjab: A case study of the Lower Chenab Canal (East) Circle Area AgEcon
Bandaragoda, Don Jayatissa; Rehman, Saeed ur.
The Directorate of Land Reclamation (DLR), which was set up in 1945, is a special unit of Punjab's Irrigation and Power Department for undertaking research and field operations to combat the problem of salinity. Approaching the end of five decades of existence, the directorate is yet to demonstrate its effectiveness in its assigned task; its inability to fully cope with the conditions of a fast changing irrigation environment makes this rather an illusive goal. In the selection of lands for reclamation, the Directorate is heavily dependent on the visual salinity survey (Thur Girdawari) carried out every year by the Irrigation Department's field staff. This visual survey appears to be a quick and cost-effective method of assessing surface salinity, but...

Land reclamation recovery with the sewage sludge use BABT
Tamanini,Cristina Rincon; Motta,Antônio Carlos Vargas; Andreoli,Cleverson Vitório; Doetzer,Benno Henrique.
In this work, investigations were carried out with five treatments [control, three doses of lime stabilized sludge (60, 120, 240 Mg ha-1 dry base) and soil corrective plus mineral fertilizer] to evaluate the immediate recuperation of a borrowed area. The application of stabilized alkaline sewage sludge acted as an acidity corrective, allowed the increase in the organic matter contents (21 to 43.5g dm-3) and available P (44 to 156 mg dm-3). Even with the use of the highest dose, no increase in the concentration of 32 analyzed metals was observed, due to the low concentration of metals in the sludge. The experiment showed that short term restoration of degraded area was possible by using high rates of sewage sludge without metal contamination.
