CaracterĂsticas da chuva e perdas por erosĂŁo sob diferentes prĂĄticas de manejo do solo Rainfall characteristics and erosion losses for different soil management practices
Objetivou-se com este trabalho, avaliar as relaçÔes entre a erosividade da chuva e os padrĂ”es da precipitação com as perdas por erosĂŁo, para diferentes tipos de preparo do solo em um Argissolo Vermelho-Amarelo. O experimento foi conduzido utilizando-se parcelas experimentais de perda de solo com dimensĂ”es de 3,5 x 22,0 m, com os seguintes tratamentos: preparo convencional do solo em nĂvel e semeadura de Mucuna Cinza (Mucuna pruriens), CrotalĂĄria (Crotalaria juncea), e Milho (Zea mays L.); preparo convencional do solo no sentido do declive e semeadura de milho no mesmo sentido e preparo convencional do solo no sentido do declive, mantido sem qualquer tipo de cobertura. Foi possĂvel evidenciar que as perdas de solo foram mais influenciadas pelos diferentes tratamentos que as perdas de ĂĄgua; os tratamentos CrotalĂĄria e Milho morro abaixo, foram aqueles que apresentaram, respectivamente, as menores e maiores perdas de solo e ĂĄgua e, em mĂ©dia, os eventos de precipitação caracterizados como avançado, intermediĂĄrio e atrasado, foram responsĂĄveis por 62,6, 11,8 e 25,6% das perdas de ĂĄgua e por 35,1, 6,6 e 58,3% das perdas de solo, respectivamente.<br>This study was carried out in order to evaluate the relation between erosivity index and the rainfall pattern associated with different kinds of soil preparation and cover with erosion losses in a Red Yellow Argisol. The experiment was conducted in five soil loss experimental plots of 3.5 x 22.0 m, with the following treatments: conventional tillage (plowing plus disking) in contour lines and sowing the velvet bean (Mucuna pruriens), sun hemp (Crotalaria juncea) and corn (Zea mays L.); conventional tillage (plowing plus disking) in slope line and sowing of corn, conventional tillage (plowing plus disking) in slope line and without soil cover. The results showed that soil loss was more affected by different treatments than water loss; the treatments sun hemp and corn sowed in slope line were those that presented, respectively, the smaller and the larger soil and water losses; and the precipitation events characterized as advanced, intermediate and delayed patterns were responsible for 62.6, 11.8 and 25.6% of the water losses and for 35.1, 6.6 and 58.3% of the soil losses, respectively
Check-list of the Family Lamiaceae in Pernambuco, Brazil
A survey of the family Lamiaceae in the state of Pernambuco revealed the presence of 20 genera encompassing 46 species. The genera with the highest number of exsiccatae were Hyptis and Ocimum; others had little representative material, and some taxa were collected only once. Regarding the phytogeographical distribution in the state, 9.1% of the registrations of species occurred in the coastal zone, 54.5% in the forest zone and 36.3% in the caatinga zone.<br>O levantamento da famĂlia Lamiaceae no estado de Pernambuco revelou a existĂȘncia de 20 gĂȘneros aos quais estĂŁo subordinadas 46 espĂ©cies. Os gĂȘneros com maior nĂșmero de exsicatas foram Hyptis e Ocimum, outros tiveram poucos materiais representativos, existindo aqueles coletados uma Ășnica vez. Com relação a distribuição fitogeogrĂĄfica no estado, 9,1% dos registros de espĂ©cies sĂŁo da Zona do Litoral, 54,5% da Zona da Mata e 36,3% da Zona da Caatinga
