Tóth, T. and K. Rajkai. 1994. Soil and plant correlations in a 
solonetzic grassland. Soil Science. 157.253-262.

On the Great Hungarian Plain, the correlation between soil variables 
and plant data was studied in a heterogeneous solonetzic grassland. 
A 21-m transect was sampled toidentify the basic features of the 
soil-plant correlations. The abrupt change form nonsaline meadow to 
salt-affected grassland vegetation was explained by the sharp increase 
in the sodium concentration of the groundwater. Two 50-m transects 
were sampled, and the relationship between soil variables and plant 
data was used to predict soil variables. The observed data of the 
50-m long transects were divided into two groups of plants,, one 
used for te multiple regression equations and the other used as a 
check. When comparing the efficiency of various groups of variables 
for estimation, plant cover data was only half as precise as soil data.
