The Impact

Soils in an agricultural landscape on the southern coast of Finland (60° 13'N 25° 02'E) were characterized and classified according to Soil Taxonomy, the FAO-Unesco system (FAO), and the World Reference Base for Soil Resources system (WRB). The impact of human activity (

The South African Taxonomic soil classification system (SAT) is well established and utilised in South Africa. However, it is not internationally well known and therefore the need arose to provide a tool by which South African soil taxonomists can convert South African soil classifications and profile descriptions to the international classifications of the World Reference Base (WRB) for soil resources. The diagnostics and tacit knowledge presented in this publication are therefore based on the SAT and the WRB. When necessary, further substantiation was derived from the Land Type Survey of South Africa. The adopted procedure is effective in providing a reasonable classification based on the South African soil forms and families, while excluding certain WRB soil groups and qualifiers, because these are irrelevant to South African taxonomy. Lastly, this publication also highlights some peculiarities, omissions and inconsistencies observed between the SAT and WRB.

A tanulmány célja az volt, hogy felmérje a legnagyobb hazai területi lefedettséggel rendelkező, túlnyomóan archív adatokat tartalmazó talajtani adatbázisok harmonizációs lehetőségeit nemzetközi adatbázisokkal. A cikk fókuszában a Világ Talaj Referenciabázis (World Reference Base for Soil Resources, WRB) rendszere által meghatározott követelmények állnak, mivel számos modern adatbázis talajadat-struktúrája igyekszik alkalmazkodni annak követelményeihez. Négy kiválasztott adatbázison vizsgáltuk, hogy a rendelkezésre álló adatok alapján lehetséges-e meghatározni alapvető, a hazánk környezeti viszonyai között előforduló WRB egységeket. Mindegyik adatbázis saját módszertanából kiindulva egyszerűsített algoritmusokat hoztunk létre, hogy a lehető legtöbb archív információ hasznosuljon. Az eredmények alapján látható, hogy a WRB rendszerét adoptáló adatbázisokba a hazai archív talajadatok korlátozott mértékben ugyan, de beilleszthetőek. Megfigyelhető továbbá, hogy míg az egyes archív adatbázisok önmagukban csupán korlátozott információt nyújtanak a WRB számára, kombinációjukkal ez az információhiány jelentősen csökkenthető.

A reconnaissance survey conducted at the University of Ilorin Sugar Research Farm (USRF) revealed four dominant soils at Site 1 (USRF1) and one at Site 2 (USRF2). The soils were characterized and classified according to both the Soil Taxonomy (ST) and the World Reference Base for Soil Resources (WRB). Also, the suitability of the soils for sugarcane cultivation was evaluated using the limitation approach. While the USRF1 soils were reddish, the USRF2 soil was greyish due to poor drainage. The USRF1 soils were loamy sand with the AB-horizons of pedons II and III being gravelly. Pedon V had sandy loam surface, sandy clay loam subsurface and clay loam subsoil. The USRF1 soils were moderately acid while the USRF2 soil was slightly acid to slightly alkaline. Exchangeable calcium (Ca2+) content of the USRF2 soil which averaged 4.00 cmolc kg–1 was 2-3 times higher than that of the USRF1 soils. The USRF2 soil also contained higher Mg2+, K+ and Na+, 2-3 folds higher effective cation exchange capacity and > 10 folds higher soil organic carbon (with mean of 11.60 g kg–1) and total nitrogen (mean of 0.94 g kg–1). Under ST, pedons I and IV classified as Typic Haplustepts, II and III as Lithic Haplustepts and V as a Kanhaplic Haplustalf. Under WRB, pedons I and IV classified as Eutric Regosols (arenic), II and III as Endo-pisoplinthic Cambisols (arenic) and V as a Gleyic Lixisol (loamic). Pedon V was highly suitable (85.25%), I and IV moderately suitable (64.53%), II marginally suitable (47.40%) and III unsuitable (35.62%) for sugarcane cultivation.
