Wetland carbon storage is an importantand environmentally sensitive ecosystem service. Carbon burial in the floodplain lakes of the Pantanal(tropical South America) appears to have varied during the late Quaternary, but several paleolimnological studies have recorded unusually high sedimentorganic carbon content from ~7.3 to 6.0 cal kyr BPin lakes connected to the Upper Paraguay River. We conducted a multi-indicator (phytoliths, sponge spicules, and geochemistry) study of a sediment corefrom Lake Caceres (Bolivia), and found evidence for enhanced organic carbon burial during the middle Holocene that provides insights into the flooding history of the Upper Paraguay River.d13Corgand C/Ndata suggest that organic matter deposited at that timein Lake Caceres was from macrophytes. Similar datasets from three other floodplain lakes are consistent with this finding. We suggest that enhanced carbon burial occurred when lake levels declined under relatively dry climate conditions, which increased the littoral area at the expense of open waterand captured floating macrophyte islands. This studysheds new light on hydroclimate controls on carboncycling in the Pantanal wetlands, and improves interpretations of geochemical measures on bulk organic matter in floodplain lake cores. |

The objective of this work was to evaluate the stalk yield, technological quality parameters, and sugar and alcohol productions in the first sugarcane (Saccharum officinarum) crop cycle, according to the response to N and K2O applications by subsurface drip fertigation. The experiment was carried out in a dystrophic Ultisol, in a randomized complete block design with four replicates. The treatments consisted of a 2X + 2X + 1 incomplete factorial arrangement with the application of 60, 80, 120, 160, and 180 kg ha-1 N and 60, 80, 120, 160, and 180 kg ha-1 K2O. The maximum estimated yield (217.5 Mg ha-1) was obtained with the application of 180 kg ha-1 N and 60 kg ha-1 K2O. Sugar and alcohol productions increased with N application above 120 kg ha-1. The technological quality characteristics of soluble solids content, apparent sucrose in the juice/broth, apparent sucrose in sugarcane, purity, and fiber show the highest averages with the application of 180 kg ha-1 N and 60 kg ha-1 K2O. |
