Soil erosion is a critical socio-environmental problem for rural Mediterranean ecosystems and landscapes. Erosion inflicts multiple, serious damages in agro-ecosystems, including vineyards and olive groves, and also in other semi-natural ecosystems such as the Montado (cattle-sheep pastureland combined with Quercus sp. trees). In particular, erosion reduces the water storage capacity, soil organic matter, nutri...
A study was carried out to assess if the visual soil assessment method (VSA) would allow recognizing differences between soils receiving organic matter (OM) amendments and similar control soils, by the observation of visual soil quality indicators’ score. 36 practices were identified across 8 pedoclimatic zones. These fields/plots were paired with nearby control fields/plots, without OM amendments, sharing simi...
1 Introduction. When growing crops, the eradication of plants from a field has only a temporary effect and, soon after, it is readily recolonized from the soil seedbank, vegetative structures in the soil and by seeds transported to the field by wind, run-off water, animals, soil mass movement or even agricultural practices (irrigation, harvesting, manuring, tillage etc.). We must be grateful for the tenacity th...
In Cape Verde, small family farming production suffers continuously from limited essential resources such as water and soil for a steady development. This situation is further aggravated by the lack of financial resources. We have developed a hybrid and multidimensional conceptual model for improvement of those small farming units by bringing together concepts of quality management, farmers’ satisfaction evalua...
Advising farmers on the best agricultural management practices (AMP) to be adopted in order to sustain agricultural productivity while improving soil quality is mandatory to assure future food production. Some promising AMPs have been suggested over the time to prevent soil degradation. These practices have been randomly adopted by farmers but which ones are mostly used by farmers and where they have been appli...
Nos anos agrícolas de 2012/2013 e 2013/2014, realizaram-se na Herdade Experimental da Almocreva (Beja) quatro ensaios de campo (dois em cada ano) com o objetivo de estudar a eficácia e seletividade na cultura da cevada dística do herbicida iodossulfurão-metilo-sódio (50 g L-1) + mesossulfurão-metilo (7,5 g L-1). Em cada um dos ensaios, aplicaram-se três doses (5,0 + 0,75; 7,5 + 1,125 e 10,0 + 1,5 g s.a ha-1) do...
iSQAPER project - Interactive Soil Quality Assessment in Europe and China for Agricultural Productivity and Environmental Resilience - aims to develop an app to advise farmers on selecting the best Agriculture Management Practice (AMPs) to improve soil quality. For this purpose, a soil quality index has to be developed to account for the changes in soil quality as impacted by the implementation of the AMPs. Som...
A data de sementeira do trigo mole exerce uma influência relevante no crescimento e desenvolvimento da cultura, condicionando a sua produtividade. O seu efeito é, especial-mente, importante sob condições mediterrânicas. Por isso, neste trabalho procurou-se verificar a influência da data de sementeira no rendimento do trigo mole, a partir de um ensaio de quinze genótipos semeados em datas diferentes durante cinc...
O estudo realizado tinha como objectivo verificar a capacidade de adaptação de genótipos de trigo mole, quantificada pela resposta produtiva, às condições mediterrânicas em função do seu ciclo vegetativo. Devido à irregularidade das chuvas de Outono, que afecta a data óptima de sementeira, é de extrema importância para a cerealicultura das regiões mediterrâneas. Na experimentação efectuaram-se diferentes datas ...
O estudo realizado tinha como objectivo verificar a formação do rendimento de genótipos de trigo mole em função das componentes da produção, sob a influência da irregularidade das condições ambientais mediterrânicas. Para existir variabilidade das condições ambientais, a experimentação foi realizada com diferentes datas de sementeira de quinze genótipos de trigo mole durante quatro anos. O delineamento experime...
