| الوصف: | The aim of the study. To carry out a comparative assessment of the magnesium status in soils, situated on the various hypsometric levels of sloped agrolandscape and with different soil organic matter content by measuring total, mobile (exchangeable) and water-soluble magnesium in soils and to compare different analytical methods for determining magnesium in soils and plants. Location and time of the study. The study site was located in the Cis-Salair drained plain in the south-east of West Siberia (55˚02΄20˝N; 83˚50΄00˝E), administratively being within the boundaries of the Toguchin district of the Novosibirsk region, Russia. Altitude increments were marked on the slope positions of the investigated plot of 225 hectares in area and 4 km in length: the upper part of the slope BCI (280-310 m a.s.l. ), the midslope BCII (260-280 m) and BCIII (220-260 m), and the lower slope BCIV (190-220 m) (see figure 1). Soil and plant samples were collected in July 2013. Materials and methods. Prevailing soils were podzolized and leached chernozems, dark-gray and gray-forest soils according to the classification of soils of the USSR (1977), which correspond to clayey-illuvial eluvialed and dark-tongue agrochernozems, agro-dark gray soils and agro-gray soils to according of the Russian soil classification (2004, 2008), or Luvic Greyzemic Chernozems, Haplic Chernozems, Luvic Greyzemic Phaeozems, Luvic Retic Greyzemic Phaeozems by WRB Soil Classification (2014) (see table 1, figure 1). Individual soil samples (n=55) were taken with a drill from 0-30 cm layer (ploughed horizon) according to an irregular grid. The aboveground phytomass stock of oat-pea mixture (n=38) was collected using the hay cutting method on the 0.25 m2 area. The geographical coordinates of the soil and plant sampling sites were determined using the geopositioning system (GPS, Garmin eTrex Vista). The soil samples were analyzed for organic carbon content by dichromate digestion. Overall the studied soils were grouped according to soil organic matter (SOM) content ... |
