The Effect of the Soil Compaction on the Contents of Alfalfa Root Reserve Nutrients in Relation to the Stand Density and the Amount of Root Biomass

Original language description

The reserve root nutrients influence the overwintering, regrowth, yield, and persistence of alfalfa plants. The total amount of the root reserves is considered more important than their concentration. One of the factors which can affect the reserve content can be the soil compaction. The aim of this study is to clarify the effect of the soil compaction on the reserve root nutrients in relation to the stand density and the amount of the root biomass. In this experiment, the stand density ranged from 28 to 112 plants per m2. The average soil bulk density in the uncompacted and compacted variants was found to be 1.38 and 1.52 g/cm3, respectively. In spring and autumn periods, the root samples were taken from an area of 0.25 m2 (the depth 150 mm) in four replications. The number of plants, the root weight, and the concentrations of starch, saccharose, fructose, and crude protein were assessed in each plot. The total amount of the root reserves was calculated from the determined concentrati
