Aggregate size distribution of humogley after an autumn tillage
Апстракт
This paper presents results of dry aggregate size analysis of non-carbonate Humogley after the autumn tillage for wheat seeding. The 140 soil samples have been taken from square area of 90 m in length and 60 m in width, at depths of 0-5 cm and 5-10 cm. Structural aggregates larger than 9.5 mm were dominant in samples at depth of 0-5 cm, 51.67%. In contrast, the fractions larger than 50 mm have not been evidenced in any of acquired soil samples. This way, the regular conditions of Humogley has been confirmed and, therefore, its applicability for soil aggregate analysis and testing of the appropriate models has been verified too. Among others, presented results also show the large discrepancies of mean weight diameters of structural aggregates at different sample sites over the experimental plot. The analogue difference has been evidenced between the sample sites at depths of 0-5 cm and 5-10 cm. It follows that analysis of the representative distribution of soil structural aggregates of ...any plot demands analysis of large number of soil samples, acquired over the whole area of the plot.
