Özet:

 

The main objective of this paper is to assess the spatial variability of arbuscular mycorrhizal (AM) spore numbers in following two contrasting soil uses. Adjacent plots, one irrigated farmland and the other dry farmland, were marked on a transect (300 m long), with 10-m spacing. Soil samples were collected at 0-30 and 30-60 cm depth and were then analyzed for AM spore numbers and some other soil properties. The analytical results were submitted to different kinds of analysis: classical statistical and geostatistical analysis which showed that coefficient of variations (CV's) and standard deviations for spore numbers  in both farmlands were considerably low. Variations of spore numbers in irrigated farmland was lower than those in dry farmland. The soils of irrigated farmland was found to be much more homogeneous than the adjacent dry farmland soil. The results showed that in both farmland, CV's of spores numbers in topsoil horizon were lower than those of subsoil horizon. The pattern of spatial variability of this soil property was found to be different for the two lands. Spore numbers of AM fungi in topsoil and subsoil of irrigated farmland exhibited spatial dependence at the sampled scale and their experimental semivariograms were adjusted to a spherical and linear model respectively. However these data for dry farmland did not exhibit spatial dependence.
