Title:
 On the distribution of available phosphours in solis of Lublin voivodeship. Parameter estimation for the Weibull distribution in the case of censored sample

Language: Polish

Keywords:
available phosphorus
Weibull distribution

comparison method
maximum likelihood estimators

Summary:
The paper concerns agrochemical soil testing towards content of available phosphorus. The Weibull distribution is adopted to approximate the data. Graphical technique, comparison method and maximum likelihood estimators are applied to censored sample. Tests of goodness of fit are also performed. In addition, the proportional share of soils in respective categories is evaluate.
