“…The distributions of average root length density of the cherry trees were highest at around 20 cm depth and decreased with increasing depth. In similar studies, the percentage of roots in the shallowest 10 cm of soil accounted for up to 32% of the total roots distribution of peach trees 33,34 , while for apricot and peach trees a cumulative 75–80% of roots was observed in the top 0.5 m of the soil profile. The use of water stable isotopes is also a promising approach to help calibrating RWU models.…”

Tree rooting strategies are driven by external and internal factors such as climate conditions (rain frequency, wind direction), soil structure and crop type. In order to ensure water efficiency for irrigated crops, it is essential to know how each crop adapts its rooting strategy. We couple Mise-a-la-masse (MALM) with Electrical Resistivity Tomography (ERT) for investigating orange tree roots undergoing different irrigation strategies (Partial Root-zone Drying – or PRD - versus Full Irrigation). This is a totally novel approach giving an overall picture of roots structure and functioning in the subsoil. Our results show clear differences of rooting extent between different irrigation strategies, and identify privileged direction of root development due to distinct RWU patterns. These results are corroborated also by seasonal monitoring of evapotranspiration (ET) and soil water content (SWC), which exhibit very large differences in the soil water distribution in space and time for the trees undergoing different irrigation schedules.

“…Thus, the evolutionary trend of soil properties after long-term orchard exploitation, eg 10 to 15 years more, involves worsening in soil physical properties even in fertile soils like the Calcaric Calcic Chenrozems of this region. However, unlike other older orchards with various species (eg apricot, 15 years old and peach, 22 years old) in the region (Paltineanu et al, 2015(Paltineanu et al, , 2016, the soil physical properties from the cherry orchard show more favourable properties. This finding emphasizes the fact that the duration of orchard works, the soil type, and the planting distance of trees may have contributed to different soil compaction levels.…”

“…According to Black et al (2010), total root biomass distribution does not differ significantly among cherry rootstocks, yet this finding cannot be confirmed or contradicted in this paper. Cherry roots horizontally occupied the entire soil space between the studied trees after 11 years from planting and, unlike apricot and peach trees (Paltineanu et al, 2015(Paltineanu et al, , 2016, root density was much higher in the case of cherry, showing the great vigour of the rootstock. However, root density slightly decreased with distance from the trunk.…”

“…In the region, Indreias (1997) investigated the effect of rootstocks on the distribution of some fruit tree roots on chernozems, while more recently Paltineanu et al (2015Paltineanu et al ( , 2016 reported the magnitude of root distribution of mature apricot trees and peach trees as well as the effect of the technological traffic on soil properties. The common planting scheme in the region was based on the rootstock type, canopy shape, solar angle at noon, orchard management, and soil fertility (Ceausescu et al, 1982).…”

Root density was investigated using the trench method in a cherry (Prunus avium grafted on Prunus mahaleb) orchard with clean cultivation in inter-rows and in-row. Trenches of 1 m width and 1.2 m depth were dug up between neighbouring trees. The objectives of the paper were to clarify the spatial distribution of root density of cherry trees under the soil and climate conditions of the region to expand knowledge of optimum planting distance and orchard management for a broad area of chernozems. Some soil physical properties were significantly worsened in inter-rows versus in-row, mainly due to soil compaction, and there were higher root density values in in-row versus inter-rows. Root density decreased more intensely with soil depth than with distance from trees. The pattern of root density suggests that the cherry tree density and fruit yield could be increased. However, other factors concerning orchard management and fruit yield should also be considered. The results obtained have a potential impact to improve irrigation and fertilizer application by various methods, considering the soil depth and distance from trees to wet soil, in accordance with root development.

“…Besides, dried apricot skin and kernel can be processed into food and Chinese medicine. Apricot trees have vigorous and deep root systems that can extract soil water from deep layers, enabling the trees to survive in seasonal arid climates (Paltineanu et al., 2016). Historically, apricot trees were planted in scattered orchards far from arable lands.…”

Large changes in land use and land cover types have been occurring in the hill and gully regions of the Loess Plateau since the end of the 1990s. This study revealed dynamic variations of soil water in different layers of representative land use and land cover types under different annual precipitation regimes and assessed the effects on soil water circulation in large areas of apricot [Armeniaca sibirica (L.) Lam.] trees, which have extensive and deep root systems. The results show distinct soil water deficit with a water content of generally <17% (60% of field capacity) in the deep layers of the soil profile of the apricot orchards. Several years after afforestation, perennial soil water deficit layers have subsequently developed around the root zone or even extended to deeper soil layers in the apricot orchards. In the soil profiles, increasing Cl contents are not related to increasing δ 2 H and δ 18 O values. This finding suggests that the extreme deficit of soil water and dry layer developments is mainly caused by intense transpiration, rather than by evaporation alone. The occurrence and development of soil water deficit layers in the deep soil profiles were the dominant factors that caused tree growth degradation and gradual death, due to lack of adequate stored soil water in the deep layers for use during a long arid time. Thus, the large-scale establishment of arbor trees will likely lead to long-term soil desiccation in the arid or semiarid regions on the Loess Plateau.
