Burcu Özkaraova Güngör: Principles, Application and Assessment in Soil Science, ISBN 978-953-307-740-6. Hard cover, 394 pages. Publisher: InTech Janeza Trdine 9, 51000 Rijeka, Croatia Conclusion In conclusion, different statistical methods are presently available for dealing with spatial and temporal variability of soil properties and others may be developed in the future. The behaviour of the phenomenon of interest (a priori knowledge), the objective of the research work, and the nature of the available data should help the practitioner in the choice of the adequate method(s).
