“…It was reported that a common response of the root system to increasing bulk density is to decrease its length and biomass in the upper soil layer (Chen, Weil, 2010). Also, previous researches conducted by the author (Głąb, 2013) confirmed this trend for meadow fescue (F. pratensis) and Kentucky bluegrass (P. pratensis). Sometimes, the positive correlation between soil density and root characteristics was observed, particularly for perennial crops.…”

“…In the investigation with tall fescue (Festuca arundinacea Schreb. ), the soil compaction increased the dry matter, length of roots and their diameter (Głąb, 2007). This effect can be attributed to the activity of dense perennial plant roots and earthworms and is usually responsible for favourable changes in the pore system.…”

“…The consequence is restricted aeration and increased denitrification losses of N-NO 3 . Furthermore, it leads to inhibited root growth and decreases mineralization of organic N (Głąb, 2013). All these events presumably result in decreasing fertilizer efficiency and hence biomass production.…”

In recent years, soil compaction caused by agricultural machinery has been recognized as one of the main factors that can lower yields of perennial crops. At the same time changes in grassland fertilization intensity are observed. The objectives of the present study were to evaluate the interaction of different N fertilization rates and the intensity of tractor passes. This study was conducted as a field experiment located on a sandy loam soil classified as Mollic Fluvisol in Mydlniki near Krakow, Poland over a four-year period (2009)(2010)(2011)(2012). The field experiment was established with four replications in a split-plot design with fertilization as the main plot and tractor traffic as the subplot. Three levels of N fertilization: untreated (control), 80 and 160 kg ha -1 N, and four levels of tractor traffic intensity were applied using the following numbers of tractor passes: no passes (control), two passes, four passes and six passes. Nitrogen (N) fertilization significantly affected the percentage of only three species -Trifolium pratense, Lolium perenne and Festuca pratensis in the sward. T. pratense was negatively affected by with higher N rates but two grasses, L. perenne and F. pratensis, showed the opposite response. The tractor traffic significantly affected T. pratense and L. perenne occurrence in the swards. The percentage of T. pratense in the sward was reduced by tractor traffic, and this space was occupied by L. perenne. Changes in the botanical composition reflected in the herbage production. All investigated grass species increased biomass productivity in direct proportion to N rates. Only T. pratense was negatively affected by nitrogen fertilization and since 2011 it started to disappear from the swards treated with higher nitrogen rates. For all investigated components of the mixture no interaction between treatments, tractor traffic and nitrogen fertilization was observed.

“…Large number of machines and agricultural vehicles moving over fields contributes to undesirable changes in the form of an increased soil compaction (Głąb, 2013;. Crop yield decrease is considered as the best recognized and direct effect of compaction (Whalley et al, 2008), however the relationship between soil compaction and yield is not direct due to the occurrence of interactions with soil kind, as well as with water and air presence.…”

“…Too compacted a soil loses its ability of infiltration and prevents rainwater storage, which causes fast water flow and soil erosion (Cudzik et al, 2010). Soil compaction caused by multiple tractor units passing through the farm fields can cause shallow rooting of the plants and changes in roots morphological features (Bartholomew and Williams, 2010;Głąb, 2013;2012a,b;Powałka, 2008), while oxygen deficit in the soil is a reason of plants growth suppression (Balakhnina et al, 2012). The intensity and kind of cultivation which affect soil structure have also a significant meaning for microbiological activity or organic compounds content in the soil (Blouin et al, 2008;Gajda and Przewłoka, 2012;Sławiński et al, 2012).…”

The paper presents the results of an analysis of the influence of soil bulk density in a forest nursery plot on the growth and quality parameters of Scots pine and European beech seedlings. Particular density variants were obtained using a tractor device exerting controlled pressure on the soil, while field examinations were performed on an area of ‘Kłaj’ forest nursery in Niepołomice Forest District. Three series of plots were prepared for each species, applying a unit pressure of the values of 50, 100, 150, 200, 250 kPa, corresponding to the dry bulk density in the range of 1.03-1.19 g cm-3, and control plots without the pressure. Seeds of the examined species were sown on the prepared plots, and after 6 months of growth the seedlings were subjected to biometric analysis determining differentiation in root neck diameter, length of the above-ground part and root system, as well as dry mass of particular parts of the plant. The quality of the seedlings was also determined using the method of Schmidt-Vogt. The results obtained show that the change in dry bulk density soil significantly affected most of the growth parameters of the examined seedlings. Especially high negative correlations were obtained for the length and dry mass of the root system. A significant influence of dry bulk density variant on all growth parameters of Scots pine seedlings, and on some parameters of European beech was demonstrated. An increase in soil bulk density clearly caused also a deterioration of European beech seedlings quality

Interaction Between Plant Roots and Soil Water Flow in Response to Preferential Flow Paths in Northern China

et al. 2016

Preferential flow is expected to provide preferential channels for plant root growth and variations in soil water flow, but few studies were conducted to imply the impacts of these changes, particularly for preferential flow in stony soils. This study aimed to characterize soil water flow and plant root distribution in response to preferential flow paths and quantitatively describe the relation between plant root distribution and soil water flow. Field dye‐tracing experiments centered on experimental plants were conducted to determine the root length density and soil water flow process. Laboratory analyses were performed to characterize changes in the relative concentration of the accumulated effluent and the degree of interaction between plant roots and soil water flow. The amount of fine plant roots with preferential flow paths decreased with increasing soil depth for all experimental plots. The largest plant roots were recorded in the upper soil layers to a depth of 20 cm. The relative concentration of the accumulated effluent increased with time and decreased with soil depth under saturated soil conditions, whereas a distinct early turning point for the relative concentration of the accumulated effluent was observed in the 0–20‐cm soil columns, and the relative concentration of the accumulated effluent initially decreased and then increased with time under unsaturated soil conditions. This study provides quantitative information with which to characterize the interaction between plant roots and soil water flow in response to preferential flow paths in soil–plant–water systems.
