“…In all three examples (Figs. 4, 5 and 6) the soil from 0Á15 cm dried out to below the permanent wilting point, indicating that the crops were dependent on water lower in the profile supplied by capillary rise to the root zone, as reported by Parker et al (1989).…”

. Depth to compact subsoil effects on soil properties and barley Á potato yields on a loamy soil in New Brunswick. Can. J. Soil Sci. 95: 203Á218. An experiment was established to investigate the implications of thickness of soil over compact subsoil on plow layer soil thermal and water regimes and ultimately the yield of potato (Solanum tuberosum L.) and barley (Hordeum vulgare L.). Three depths were considered, 24 cm (shallow), 36 cm (medium) and 60 cm (deep). Results on soil temperature impacts were inconclusive. The shallow treatment water content was most greatly affected by precipitation and had the greatest potential to become saturated then drying out more than the other treatments. The deep treatment did not improve soil temperature and water regimes enough to increase crop yield. The medium depth, which most closely approximated existing local solum development, proved superior to the shallow treatment in terms of crop yield and reduced soil moisture variation, while the deep treatment did not warrant the effort required to create under field conditions. Barley and potato yields from the medium depth were greatest with 20% (significant) and 8% (not significant) more yield, respectively, than from the shallow treatment. The eroded soil profiles common to the New Brunswick potato belt exacerbate soil erosion since an eroded soil has less volume to accept water from a rainfall event, making the soil more prone to erosion, especially if it is true that our weather is changing, with the amplitude of weather shifts becoming greater. Incorporation of subsoil materials into the plow layer of eroded soils due to soil loss may result in further reduction in crop yield. . Les effets sur la tempe´rature du sol ne sont pas concluants. Avec la couche peu e´paisse, la teneur en eau est particulie`rement touche´e par les pre´cipitations, et le sol court plus de risques de parvenir a`saturation puis de s'asse´cher que celui des deux autres traitements. La couche la plus e´paisse n'ame´liore pas assez la tempe´rature du sol ni le re´gime hydrique pour qu'on observe une hausse du rendement. La couche d'e´paisseur moyenne, qui correspond le plus au me´canisme local de de´veloppement du sol, s'ave`re supe´rieure a`la couche peu e´paisse au niveau du rendement et re´duit la variation de la teneur en eau du sol, les re´sultats obtenus avec la couche la plus e´paisse ne justifiant pas les efforts de´ploye´s pour ame´nager celle-ci au champ. C'est la couche d'e´paisseur moyenne qui assure le meilleur rendement de l'orge et de la pomme de terre, avec une hausse respective de 20 % (significative) et de 8 % (non significative) comparativement au rendement obtenu avec la couche peu e´paisse. Le profil e´rode´des sols commun a`la ceinture de la pomme de terre du Nouveau-Brunswick accentue l'e´rosion des terres dans cette province, car un sol e´rode´est moins volumineux et retient moins bien l'eau de pluie, le rendant plus sensible a`l'e´rosion, surtout si le changement climatique s'ave`re et accroıˆt l'amplitude des variations clima...

“…During each dry spell, the soil below the bottom of the root zone also tended to dry out. This could be explained by the capillary rise towards the root zone (Parker et al 1989) and by the gravity-driven unsaturated seepage.…”

Dual permeability soil water dynamics and water uptake by roots in irrigated potato fields

et al. 2007

Water movement and uptake by roots in a drip-irrigated potato field was studied by combining field experiments, outputs of numerical simulations and summary results of an EU project (www.fertorganic.org). Detailed measurements of soil suction and weather conditions in the Bohemo-Moravian highland made it possible to derive improved estimates of some parameters for the dual permeability model S1D DUAL. A reasonably good agreement between the measured and the estimated soil hydraulic properties was obtained. The measured root zone depths were near to those obtained by inverse simulation with S1D DUAL and to a boundary curve approximation. The measured and S1D DUAL-simulated soil water pressure heads were comparable with those achieved by simulations with the Daisy model. During dry spells, the measured pressure heads tended to be higher than the simulated ones. In general, the former oscillated between the simulated values for soil matrix and those for the preferential flow (PF) domain. Irrigation facilitated deep seepage after rain events. We conclude that several parallel soil moisture sensors are needed for adequate irrigation control. The sensors cannot detect the time when the irrigation should be stopped.

“…In the Maritime provinces, this problem is aggravated further by naturally occurring compact subsoils (Saini 1980), although relatively little is known about the response of potato, a shallow rooted crop, to subsoil modification. Previous research has shown that loosening compact subsoils can have a variable effect on potato yield and quality (Ross 1986;Parker et al 1989;Pierce and Burpee 1995). Studies conducted in Nova Scotia with forages showed that the benefits of subsoil loosening were short lived while increased crop yields were minor (Carter et al 1996).…”

“…Soil compaction is often considered a problem where row crops such as potato (Solanum tuberosum L.) are grown on sandy loam soils (Parker et al 1989;Pierce and Burpee 1995). In the Maritime provinces, this problem is aggravated further by naturally occurring compact subsoils (Saini 1980), although relatively little is known about the response of potato, a shallow rooted crop, to subsoil modification.…”

Holmstrom, D. A. and Carter, M. R. 2000. Effect of subsoil tillage in the previous crop year on soil loosening and potato yield performance. Can. J. Plant Sci. 80: 161-164. Soil compaction under potato rotations can be a common problem in Prince Edward Island. This can be further aggravated by naturally occurring compact subsoils. A study was conducted at eight sites on sandy loam soils in three regions of Prince Edward Island to determine whether the recommended practice of subsoiling the fall prior to the potato crop would improve the physical condition of the soil and result in improved yields. The study found that subsoiling provided only a marginal improvement in soil physical conditions. Soil loosening did not increase potato yield or quality. La compaction du sol sous culture de pomme de terre est un problème assez fréquent dans l'Île-du-Prince-Édouard, qui se complique par la présence dans la province de sous-sols naturellement compacts. Nous avons mis en place dans trois régions de l'Île des expériences à 8 emplacements sur du loam sableux afin de vérifier si la pratique préconisée du labour profond l'automne précédent la sole de pomme de terre améliore l'état physique du sol et, par voie de conséquence, le rendement de la culture. À la lumière de nos observations, il semble que le labour profond (sous-solage) n'ait apporté qu'une très légère amélioration des propriétés physiques du sol. L'ameublissement du sol ne s'est pas traduit par un relèvement du rendement ni de la qualité des pommes de terre.
