O conhecimento das relacoes entre custo de producao e a quantidade produzida e importante na analise da estrutura de custos e da rentabilidade economica nos diferentes tamanhos de propriedade. O objetivo deste trabalho e estimar a funcao de custo total da soja no Rio Grande do Sul, derivar as funcoes de custo medio e marginal e determinar o nivel da producao que maximiza a receita liquida total. Adicionalmente, foi testada a importancia da assistencia tecnica na determinacao das relacoes de custo. Os dados utilizados foram obtidos de uma amostra de 140 propriedades nas regioes do Planalto Medio, Alto Uruguai e Missoes. Uma funcao do custo totral na forma polinomial foi estimada pelo metodo dos quadrados minimos. Os resultados indicaram que a soja e uma culturaque apresenta melhores resultados economicos quando praticada em larga escala. A receita liquida foi maximizada ao nivel de producao de 23t. Os testes estatisticos nao indicaram evidencias de que a assistencia tecnica tenha influenciado as relacoes de custo. |

In order to monitor soil biodiversity (species and function), a pilot program named « RMQS
Biodiv » was carried out at a regional scale (Brittany, France).
This program completed the French Soil Quality Measurement Network (?classical? RMQS)
which monitored soil abiotic parameters measurements (chemistry, physic) and agricultural
management practices using a regular sampling grid (16 X 16 km) covering the whole country.
The link between these two programs allowed the study of biological parameters (7 groups of
soil organisms and some biological activity index) in regards to soil and agricultural characteristics,
leading to the definition of biological indicators.
Since enormous data sets were generated, it became evident that an efficient tool of storage
and management was required.
Thus, DONECOSOL database was created in 2007 by the Ecobio team of the University of
Rennes (France). Its conceptual creation and evolution were the result of permanent discussions
within a working group, in order to meet requirements for both the RMQS Biodiv program data
and further studies. Moreover, it was designed to be compatible with the ?classical? RMQS
database in order to link the biodiversity?s parameters with potential explicative parameters
(e.g. mesological parameters, land use or management).
DONECOSOL has been developed by using a relational database management system. A
user-friendly front end was designed to optimise and facilitate consultation, and will be soon
accessible from the web.
The main related functions of DONECOSOL are:
(1) storing, handling and managing the data obtained from field samples,
(2) inventorying species of the sampled soil organisms, to establish and understand their ecology,
(3) analysing and linking taxa together, and also linking taxa to other parameters particularly
those related to the environment.
The aim of this presentation is to present DONECOSOL: its structure, its components and its
functions. MenosIn order to monitor soil biodiversity (species and function), a pilot program named « RMQS
