“…Due to the aeolian nature of the Loess Plateau, the soil horizons are highly similar across the region [41,42]. The soil texture is silt loam [20]. Groundwater in the region is more than 50 m deep and, therefore, has little effect on the root zone soil water [43].…”

“…Twelve paired-plot sites were sampled in May 2014, with each site thus containing a standing apple orchard and an adjacent cropland. The apple orchard ages were 5,8,11,12,17,18,19,19,20,22,24 and 26 years at the 12 different sites. Here, the annual cropland serves as the control site to study how soil water is depleted due to growing apple trees relative to the annual cropland.…”

“…When the apple trees were 8 years old, their roots penetrated to a depth of 9.6 m, and the roots of the 22-year-old apple trees extended to 23.2 m below the soil surface [20]. Therefore, the deepening rate of the apple tree roots was almost eight times faster than the water infiltration velocity in the flat area on the Loess plateau, supporting deep roots taking up water before it could infiltrate further into the soil [34,57].…”

“…Deep-rooted plants preferentially absorb water from shallow soil, but can soak up deep soil water that would otherwise recharge groundwater [17,18]. Li et al [19] conceptualized deep soil water depletion as a process of one-way mining: Tree roots grow deeper to mine deeper soil water and thus deplete deep soil water, which, in turn, stimulates further root growth [20]. However, when the deep-rooted trees are felled and shallow-rooted crops are planted, soil water content begins to recover, and groundwater recharge could increase by an order of magnitude after several decades of land-use change [21].…”

“…The available soil water can fall to less than 16% of field capacity for trees over 30 years old [2,22,23,25]. The roots of apple trees can grow up to 23 m deep [20], and deep-root water uptake has been reported to account for 8% of the total evapotranspiration in an apple orchard [34]. When the depletion of deep soil water reaches the maximum, there are no more deep soil water reserves accessible to the apple trees; as a result, precipitation becomes the only water source for their evapotranspiration.…”

Land-use change could substantially alter the soil water balance and hydrological cycles; however, little is known on the changes in deep soil water following a cycle of afforestation and deforestation. The purpose of this study was to quantify the soil water deficit in an apple orchard and subsequent replenishment of deep soil water after the orchard was felled. Soil water changes were quantified using the “space-for-time” method through a paired plot design. The results showed that the water storage in deep soil (>3 m in depth) began to decrease when the apple tree reached about 10 years of age. The cumulative deficit of deep soil water storage in the 3–18 m soil depth could reach about 1200 mm; however, deep soil water was so depleted that apple trees can no longer adsorb water from the deep soil when apple trees are older (>22 years old). After the apple orchard was converted to cropland, precipitation replenished the desiccated deep soil to a depth of about 7 m in the first two years, but thereafter, both water recovery amount and the advance rate of the wetting front were slowed down. After 15–16 years of recovery, soil water storage increased by 512–646 mm, accounting for 42.7–53.8% of the total cumulative soil water deficit caused by the apple orchard. However, it will take more than 26 years for soil water to be replenished to the level of the original cropland prior to planting apple trees. The considerable water deficit after afforestation and subsequent long water recovery time following deforestation extend our understanding of the effect of deep-rooted trees on water balance at the decade scale.

This study was aimed to alleviate water deficiency and improve soil fertility in orchard in semi‐arid region. The Brassica napus L. winter varieties (including the variety V6, V7) generally had higher aboveground biological yield, lower root yield and main root length compared to the Brassica campestris L. winter / spring varieties. By mulching root area of apple tree with aboveground part of these rape varieties at later autumn, the water contents in 0‐20, 20‐40, 40‐60 cm soil were enhanced /changed at following March and positively correlated with the mulching‐plant biomass. Similarly, under treatments of the V6‐I, V7‐I (the variety V6, V7 mulching), and the V6‐II, V7‐II (mulching with aboveground part of the V6, V7 + 5% soil), the average water content in 0‐150 cm soil was significantly increased by about 12%, 9%, 18%, and 14% at following spring, respectively; meanwhile the treatment V6‐II, V7‐II induced significant increase of water contents in 0‐25, 25‐50, 50‐75, 75‐100, 100‐125, and 125‐150 cm soil profile; these treatments were conducted over two years, respectively the available K, total N, and organic matter in 0‐20 cm soil was significantly increased by 39.3%‐151.8%, 10.0%‐17.9%, and 22.7%‐34.2%, the apple tree growth was promoted, the fruit yield per plant was significantly enhanced by 16.9%‐95.5%. In conclusion, the Brassica napus L. winter variety mulching, especially the mulching with aboveground part of the Brassica napus L. winter variety + 5% soil, showed significant effect in improving soil moisture, soil fertility, and fruit yield in orchard in semi‐arid region.This article is protected by copyright.

Stable isotopes of hydrogen and oxygen in water are common tools for investigating water uptake apportionment, but many of the existing methods rely on simple linear mixing approaches that do not mechanistically incorporate additional information about site physical properties and conditions. Here, we develop a ‘physically based root water uptake isotope mixing estimation’ model (PRIME) that combines a continuous and parametric probability density function for root water uptake with site physical data in a process‐based linear mixing framework. To demonstrate the application of PRIME, water uptake patterns of boreal forest Pinus banksiana trees were estimated on four dates in 2019. To aid in validation, estimates were compared with that of the Bayesian linear mixing model framework, MixSIAR. The two approaches provided similar results, but due to its continuous and parametric nature, PRIME provided estimates of superior resolution, certainty, and model parsimony. Although both models incorporate additional physical information into their mixing frameworks, PRIME does so in a mechanistic manner, thereby reflecting the relevant hydrological processes more effectively than the purely empirical approach taken by MixSIAR. Furthermore, because PRIME uses a continuous function to describe the predicted uptake pattern, it allows users to quantify water uptake with essentially infinite resolution, through integration over the desired depth ranges. These findings demonstrate the advantages of utilizing a continuous, parametric, and process‐based mixing model to estimate root water uptake apportionment, thus providing a relatively simple yet powerful tool with which to approach plant water sourcing.
