Humping/hollowing and flipping are land development practices widely used on the West Coast to overcome waterlogging constraints to pasture production. However, there is very limited information about how the resulting "new" soils function and how their properties change over time following these extreme modifications. We hypothesised that soil quality will improve in response to organic matter inputs from plants and excreta, which will in turn increase nutrient availability. We tested this hypothesis by quantifying the soil organic matter and nutrient content of soils at different stages of development after modification. We observed improvements in soil quality with increasing time following soil modification under both land development practices. Total soil C and N values were very low following flipping, but over 8 years these values had increased nearly five-fold. Other indicators of organic matter quality such as hot water extractable C (HWC) and anaerobically mineralisable N (AMN) showed similar increases. With large capital applications of superphosphate fertiliser to flipped soils in the first year and regular applications of maintenance fertiliser, Olsen P levels also increased from values

The monograph presents an overview of the forest-steppe vegetation of the West Siberian Plain and the Altai-Sayan mountain region. The questions of bioclimatic zonation of the Altai-Sayan mountain region are discussed. The biodiversity of foreststeppe is characterized, the floristic classification is performed, the scheme of eco-phytocoenotic classification is given, the basic types of plant communities are described in comparative terms. The diversity of forest-steppe landscapes is revealed, the structure of their vegetation is analyzed. The phytogeographical division of forest-steppe is worked out.
