3. Crop Response to Gypsum Application to Subtropical Soils Under No-Till in Brazil: a Systematic Review
ABSTRACT The use of gypsum to improve the root environment in tropical soils in the southeastern and central-western regions of Brazil is a widespread practice with well-established recommendation criteria. However, only recently gypsum began to be used on subtropical soils in South of Brazil, so available knowledge of its effect on crop yield is incipient a

4. Occurrence of arbuscular mycorrhizal fungi on King George Island, South Shetland Islands, Antarctica
ABSTRACT Arbuscular mycorrhizal fungi make up an important ecological niche in ecosystems, and knowledge of their diversity in extreme environments is still incipient. The objective of this work was to evaluate the density and diversity of arbuscular mycorrhizal fungi in the soil of King George Island in the South Shetland Islands archipelago, Antarctica. Fo

6. Organic matter in Albaqualf as affected by managements irrigated rice cropping systems the South from Brazil / Matéria orgânica em Planossolo Háplico sob sistemas de manejo no cultivo do arroz irrigado no Sul do Brasil
In the south region from Rio Grande do Sul State, in,Brazil, 950 thousand hectares of soils are cultivated with rice, an important agricultural activity in that region, under an irrigation (flooded) system, using different soil management techniques. Studies regarding the organic matter (OM) dynamic in these soils are incipient, so this work aimed to evaluat

7. HUMIC SUBSTANCES IN SOILS FROM DIFFERENTS GEOMORPHOLOGIC FEATURE IN THE EDGE OF RIO GRANDE DO SUL PLATEAU / SUBSTÂNCIAS HÚMICAS EM SOLOS DE DIFERENTES FEIÇÕES GEOMORFOLÓGICAS NO REBORDO DO PLANALTO DO RIO GRANDE DO SUL
In spite of the great importance of the soil organic matter for the sustainability of the natural systems and of agricultural production, its study remains incipient in the area of the Edge of the Rio Grande do Sul Plateau, where different research have been reporting negative aspects of the inadequate soil use. In that sense, the carbon distribution evaluat

8. Concentration of 226Ra in soil and sugar cane after application of calcareous, gypsum or phosphogypsum / ConcentraÃÃo de 226Ra em solo e em cana-de-aÃÃcar apÃs aplicaÃÃo de CalcÃrio, Fosfogesso ou Gipsita
All kinds of soil possess 226Ra, and its absorption by the plants, depends on the specific characteristics of each region and of the cultivated species. In different parts of the world, radioecological studies are currently developed to evaluate the transferences of 226Ra in the soil-plant system and the presence of this radioelement in human nutrition. In r

11. Evaluation of the stock and isotopic composition of carbon in the soil of Acre. / Avaliação do estoque e composição isotópica do carbono do solo no Acre.
The State of Acre is located in the extreme west of Brazil, occupying an area that had great geological influence from the mountain chain of Andes. The soils present pedologic characteristics very different from the ones found in the remaining of Brazilian Amazon, prevailing Inceptisols, Alfisols, and Ultisols, generally eutrophic, young and little weathered
