A disponibilidade do potassio da rocha potassica de Pocos de Caldas (sienito nefelinico) foi estudada em condicoes de casa de vegetacao atraves de cultivos sucessivos com milho cultivado em Latossolo Vermelho-Escuro (LVE) e Terra Roxa Estruturada (TRE), com presenca ou ausencia de calagem. A aplicacao de KC1 mostrou respostas significativas na producao de materia seca, independentemente da calagem. Estas respostas foram lineares e mais acentuadas no LVE do que na TRE, na qual, doses de KC1 maiores que 200 ppm reduziram a producao de materia seca. Apos o primeiro cultivo, a producao de materia seca foi muito pequena, e isto parece ser devido ao esgotamento do K disponivel no solo. A rocha potassica exerceu pouco efeito na producao de materia seca, mostrando efeito positivo apenas no LVE na dose de 300 ppm de K na presenca de calagem. O reduzido efeito da rocha foi devido a sua baixa capacidade de fornecer potassio, mesmo no terceiro cultivo, conforme mostram os dados de absorcao de potassio pela planta. Os dados obtidos confirmam os estudos ja realizados com a utilizacao de extratores quimicos em laboratorio, e mostram a baixa disponibilidade do potassio desta rocha para o milho. A rocha potassica "in natura" nao se presta como fertilizante potassico para o milho. |

An interview-based questionnaire survey was conducted on 31 goat properties in New South Wales and Queensland in 2013. This study has gathered information on goat herd management, reproductive performance and animal health, and has identified constraints that may limit goat productivity. Producers from high-rainfall regions reported having full blood Boer goats for stud breeding. In contrast, producers from pastoral regions had rangeland goats and Boercross goats. Overall, 87% of the producers identified a natural breeding season in goats and 61% separated kids from their mothers at weaning. The weaning age varied between 3.0 and 6.0 months. A total of 52% of producers castrated male kids. Only 10% of producers used ultrasound to conduct pregnancy diagnosis on their goats. The reported pregnancy rate was 60% for the pastoral regions and 94% for the high-rainfall regions. The average prolificacy was 1.4 kids/doe and the kidding interval was 12 months. Overall, 68% of producers fed their goat herd with supplements, with the exception that most producers from western New South Wales and south-western Queensland did not use supplements. Producers considered gastrointestinal parasites (61%) and body lice (48%) as the main diseases ssociated with their goat herds, although only 52% mentioned drenching the animals with anthelmintics. In general, properties in the pastoral regions showed low pregnancy and kidding rates, early age at first mating, high mortality rates, poor performance of Boer bucks and lower weights and weight gain compared with properties in the high-rainfall regions. The survey has highlighted areas that require further study to validate the observations of producers, for instance, factors that may be limiting the fertility of Boer goats in rangeland environments, the incidence of diseases, the use of Kidplan and management activities to improve goat productivity.
