“…While considering the effect of summer temperature differences, it is considered that the root growth responses measured in here are primarily influenced by the physical properties of the soil, in particular the resistance the soil offers to the penetration of new roots. This finding is in accordance with international research involving a variety of different tree and crop species [12,[22][23][24][25]. It is also considered that the resistance of the soil measured as its bulk density can be a limiting factor affecting pole root development and survival in years with lower than normal summer rainfall [22,26].…”

“…Higher poplar root densities in light compared to heavy soils have also been related to lower water and nutrient availability [12,24] but in these studies the influence of soil bulk density was not considered since the coarse roots were only investigated to 0.2m depth, and fine roots to 0.4m depth. Root growth of potted plants of the leguminous tree Faidherbia albida was greater in lighter sandy soil than in clay soil [24], in contrast with the findings of the present study. We suggest that field -based measurements to a greater soil depth better demonstrate the effect of soil bulk density on poplar root development from poles.…”

“…Lateral root extension is important for gathering nutrients and water, and to a lesser extent, stabilising the tree [24,34,35]. Deep root extension enables the tree to explore a greater volume of soil for water, particularly in periods of low precipitation [32].…”

Populus deltoides × nigra trees were grown from 3m-long poles on slopes in three different soil types, pumice, sandy loam and clay loam, to test the hypotheses 1) root development differs with soil type, 2) within each soil type, root production decreases as soil bulk density increases.Methods: Over a three-year period, above-ground growth parameters and root distribution (biomass, length and root diameter size classes) of excavated root systems were measured each year at the end of the growing season, relative to distance from the pole, slope and soil depth.Results: Soil bulk density near the ground surface was least in pumice (0.65g cm 3 ) and similar for clay loam (1.05g cm 3 ) and sandy loam 1.1g cm 3 ), respectively. For all three soil types, bulk density increased with depth, at 0.9m depth being lowest in pumice soil and highest in sandy loam. In each of the three years of the trial, root length (RL), root mass (RM) and root extension were greatest in the pumice soil and least for trees growing in the sandy loam. Both RL and RM were greater in the clay loam than in the sandy loam but much less than in pumice. The percentage of poplar root mass found in the top 50cm of soil was 90 -100% in the sandy loam, 79-94% in the clayloam and 56-86% in pumice. Poplar roots reached 1.3m depth in the pumice but did not exceed 1.0m depth in the other soil types. Mean RM in Year 3 in the pumice soil (948g) was ~ 13 x that in the sandy loam (75g) and 2.3 x that in the clay loam (421g). The length of roots >1mm diameter in Year 3 in the pumice (144.2m) was ~ 9 x that in the sandy loam (15.6m) and 2.3 x that in the clay loam (63.9m). RM and RL distribution up slope and downslope varied with soil type, tree and year, and favoured neither slope direction. The mean volume of soil occupied by poplar roots in pumice, clay loam and sandy loam soils in Year 1 was 3.5, 1.3 and 0.6m 3 , respectively, and in Year 3 was 20.5, 6.5 and 3.0m 3 , respectively. Conclusion:Root length and RM of Populus deltoides × nigra trees were negatively correlated with soil bulk density, with root length and mass increasing as bulk density decreased. The results suggest that the rate at which root systems of these poplars will occupy a particular volume of soil and utilise its available water and nutrients will be faster in soils of lower bulk density. This is expected to increase rates of survival during the early years of establishment, particularly in years with drought.

“…On the basis of seed analysis, Ibrahim et al [7] highlighted three ecotypes of F. albida in Africa: the Sahelian ecotype, the South African ecotype, and the ecotype that overlaps between the two zones, particularly in Ethiopia. In the same ecological zone, F. albida has contrasting morphological and growth variability [8][9][10][11][12].…”

Faidherbiaalbida is an agroforestry tree species playing important agroecological and socioeconomic roles in arid and semiarid zones in Africa. For many years, anthropogenic and abiotic stresses were considered as the main threats for the species in West African parkland agroforests. Considerable dieback has recently occurred in F. albida trees of parkland agroforests in central southwestern Niger, and the causes are unknown. The objectives of this study are to (i) investigate the magnitude of dieback of F. albida trees and (ii) assess local community perceptions of the effects of F. albida dieback on crop production. The health status and phenology of 213 F. albida trees were observed in the area where the dieback is occurring. Similarly, a sample of 144 people, 86% of which were farmers, was surveyed. Dieback incidence of F. albida trees was 19%, with mortality of 6%. Large-diameter trees had greater dieback than small-diameter trees. The most affected parts of the tree were the branches at 54% and the trunks at 39%. The populations noted a 33–55% reduction in the yields of major crops. This dieback of F. albida trees poses a serious threat to the survival of rural communities. Further studies can be conducted to identify the cause or cause of the dieback to guide the suitable agroforestry parkland management strategies.

“…Moreover, the growth of seedlings of V. etbaica can increase by 14% by reducing the water deficit level (Birhane et al 2015). In the case of F. albida, improvements in root growth and development at the seedling stage can determine the quality of the root system throughout the tree's entire life (Gachuiri et al 2016). Through simulations, Sida et al (2017) predicted that increasing the survival rate of seedlings by 30% will increase tree density by 15%.…”
