The structure of land is one of their most important characteristics.
Substantially influence the structure of the many features and processes in the soil is
generally accepted. Soil aggregates are strongly influenced by human activities,
including land use, tillage, application of manure and growing crops. Size of aggregates
and their stability are interconnected to describe soil structure. Size distribution and
aggregate stability after the break, are used to calculate quantitative stability index. In
the classical approach to statistical analysis of soil structure are used: Gaussian normal
function, and log-normal, Rosin-Rammler and Gaudin's-Schuhmann's functions. In
addition to these distribution models recently introduced models are based on a
dimensionless statistical moments and the log-hyperbolic distribution. Uticaj strukture zemljišta na osobine i procese u zemljištu je opšte
prihvaćen. Zemljišni agregati su izloženi raznim uticajima, uključujući korišćenje
zemljišta, obradu, aplikaciju stajnjaka i gajenje useva. Veličine agregata i njihova
stabilnost međusobno su povezani. Stoga se raspodele veličina i stabilnost agregata,
posle razbijanja, koriste za izračunavanje kvantitativnih indeksa stabilnosti. Klasična
statistička analiza strukture zemljišta se oslanja na: normalnu, log-normalnu, Rosin-
Rammler-ovu i Gaudin-Schuhmann-ovu funkciju raspodele. Pored navedenih, u novije
vreme uvedeni su i modeli zasnovani na primeni viših statističkih momenata i
hiperboličke raspodele.
