CHANGES OF CHOSEN PROPERTIES OF SANDY SOIL IN RESULT OF COMPOST APPLICATION
Journal Title: Colloquium Biometricum; Colloquium Biometricum (Online) - Year 2016, Vol 46, Issue
Abstract
In this paper, the analysis of variance of the results of experiment conducted in laboratory conditions is described. The objective of this study was to evaluate changes in soil reaction, hydrolytic acidity, sum of bases and available potassium and magnesium in sandy soil incubated with two doses of composted sewage sludge (30 and 120 Mg per hectare) over period of 180 days. The data obtained showed that with regard to the unamended soil, both the 30 and 120 Mg per hectare treatments similarly influenced on analyzed properties but the effect was more visible at the case of the higher compost dose. Additionally it was found, that compost prepared on the basis of sewage sludge is an important source of potassium and magnesium. During incubation process the patterns of changes of hydrolytic acidity and available potassium and magnesium were different for particular treatments

LOGIC REGRESSION FOR DIAGNOSTIC CLASSIFICATION BY MEANS OF BIOMARKER PANELS
Biomarkers can indicate a variety of health or disease characteristics, including the level or type of exposure to an environmental factor, genetic susceptibility, genetic responses to exposures, markers of subclinical o...
On the efficiency of orthogonal treatment contrasts in multistratum incomplete split-split-plot designs constructed by square lattice designs
We construct an incomplete split-split-plot design for three factor experiments. The method is based on a semi-Kronecker (Khatri-Rao) product of three matrices. We use two square lattice designs for whole plot treatments...
NEW CONSTRUCTION OF D-OPTIMAL WEIGHING DESIGNS WITH NON-NEGATIVE CORRELATIONS OF ERRORS
In this paper, the regular D-optimal chemical balance weighing designs with equally non-negative correlated errors are considered. Here we study the issues regard to the existence conditions of optimal designs. Presented...
The growth curve model with heterogenous fractional decreasing correlation structure
In this text we will derive estimators of unknown parameters for growth curve model with different decrease of dependency in groups and we will compare them for the case of two groups. We will use method of maximum likel...
A REMARK ON ESTIMATING DEFECTIVENESS IN SAMPLING ACCEPTANCE INSPECTION
Summary The problem of estimating a probability of success in a Binomial model is considered. The classical estimator is compared with the estimator which uses the information about non-homogeneity of the sample. An appl...
