Influence of organic amendments on soil structure and soil loss under simulated rain

Abstract: The influence on soil properties and soil loss under simulated rain, of four organic by-products (cotton gin crushed compost (CCGC), by-product obtained after the two-step olive oil extraction process (BOO), sewage sludge (SS) and organic municipal solid by-product (MSW) applied annually at 10,000 kg organic matter ha −1 , was studied over 4 years on a Typic Xerofluvent under dryland conditions near Sevilla (Spain). All organic by-product treatments reduce bulk density, aggregate instability and soil loss. The CCGC and BOO treatments had similar effects and were more effective than SS and MSW treatments. Compared with the control (no organic amendment) treatment, CCGC and BOO treatments reduced bulk density by 20% and 19%, respectively, aggregate instability by 33% and 28%, respectively, and soil loss under simulated rain at 140 mm h −1 by 32% and 30%, respectively. Compared with the control treatment, the SS and MSW treatments reduced bulk density by 12% and 9%, respectively, aggregate instability by 16% and 14%, respectively, and soil loss under simulated rain at 140 mm h −1 by 23% and 19%, respectively. The stronger effects of CCGC and BOO might have been because they had humic acid contents than SS and MSW.

Central precocious puberty in children living in Spain: incidence, prevalence, and influence of adoption and immigration.

Abstract: Context: No epidemiological data are available on central precocious puberty (CPP) in the general population or in adopted or immigrant children in Spain. Objective: We aimed to study the incidence and prevalence of CPP, assess the risk of developing this disorder among adopted and immigrant children, and analyze the predictive variables of CPP associated with intracranial pathology. Design, Settings, and Patients: An observational study of children diagnosed with CPP in Spain was carried out between January 2008 and January 2010. A computer program was designed to process clinical and biological data and information on 250 patients treated in 34 pediatric endocrinology units throughout the country. Results: Of the patients registered, 226 were girls and 24 were boys. The global incidence rate of CPP was 5.66 cases per million person-years at risk, with an annual incidence ranging between 0.02 and 1.07 new cases per 100,000. The relative risk of CPP in domestic and internationally adopted children compare...
