Kovács, D., T. Tóth, and P. Marth. 2006. Study of food chain element transport analogy: 
salinity/sodicity/alkalinity of Hungarian soils during a decade as shown by the 
national soil monitoring network. Cereal Research Communications. 34: (No.1) 
231-234. 

All information available about temporal and depth changes in easily soluble 
ions in the soil solution can be utilized when inferring on the transport of the 
elements of food chain. The results of the monitoring of soil salinity thus can 
facilitate the understanding of changes in cations occurring in soil solutions, 
such as ammonium.
The statistical analyses of any monitored data must be carefully planned in 
order to provide the optimal background data (independent data) from all 
those available to accompany the monitored soil data (dependent variable).
