Phosphate Management for High Soybean and Maize Yields in Expansion Areas of Brazilian Cerrado
نویسندگان
چکیده
The low phosphorus (P) availability is considered one of the most limiting factors for suitable crop production in Brazilian Cerrado areas. We aimed to define best P fertilizer management maximum soybean and maize grain yield minimum soil adsorption new agricultural Two experiments were carried out a Hapludox (pH 5.0) over six years. first experiment evaluated five (correction maintenance): correction maintenance at furrow; incorporated furrow broadcasted; gradual (five years) furrow. second doses P2O5: 0, 60, 120, 180, 240, 300 kg ha−1 year−1 applied or broadcasted. (0–20 cm) resulted higher labile P. increased up 250 P2O5, fractions linearly increased, independent application mode. Thus, would be full bulk initial (up P2O5) essential These results are useful orientating decisions sustainable systems.

Cryptic lineages and Pleistocene population expansion in a Brazilian Cerrado frog.
Diversification of South American species endemic to open habitats has been attributed to both Tertiary events and Pleistocene climatic fluctuations. Nonetheless, phylogeographical studies of taxa in these regions are few, precluding generalizations about the timing and processes leading to differentiation and speciation. We inferred population structure of Hypsiboas albopunctatus, a frog widel...
متن کاملAn analysis of ozone damage to historical maize and soybean yields in the United States.
Numerous controlled experiments find that elevated ground-level ozone concentrations ([O3]) damage crops and reduce yield. There have been no estimates of the actual yield losses in the field in the United States from [O3], even though such estimates would be valuable for projections of future food production and for cost-benefit analyses of reducing ground-level [O3]. Regression analysis of hi...
متن کاملBrazilian Cerrado Soil Actinobacteria Ecology
A total of 2152 Actinobacteria strains were isolated from native Cerrado (Brazilian Savannah) soils located in Passos, Luminárias, and Arcos municipalities (Minas Gerais State, Brazil). The soils were characterised for chemical and microbiological analysis. The microbial analysis led to the identification of nine genera (Streptomyces, Arthrobacter, Rhodococcus, Amycolatopsis, Microbacterium, Fr...
متن کاملStructure and composition of bacterial and fungal community in soil under soybean monoculture in the Brazilian Cerrado
Soybean is the most important oilseed cultivated in the world and Brazil is the second major producer. Expansion of soybean cultivation has direct and indirect impacts on natural habitats of high conservation value, such as the Brazilian savannas (Cerrado). In addition to deforestation, land conversion includes the use of fertilizers and pesticides and can lead to changes in the soil microbial ...
