Maintenance and analysis of soil structure

Abstract

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. .
