“…Additionally, Meek and Stolzy (1978) showed that soil water content above or even below field capacity impairs air exchange between the soil and the atmosphere. Another study reported that the water use efficiency of cotton was greater with soil aeration in a heavy clay soil (Bhattarai and Midmore, 2009). Our previous studies have also shown that artificial soil aeration can improve the tomato (Lycopersicon esculentum Mill.)…”

Artificial soil aeration can enhance soil enzyme activity, improve soil nutrient cycling, and increase crop growth and yield. We studied the response of soil microorganisms and soil enzyme activity to two levels of burial depths of subsurface tubing in combination with four levels of aeration volume and three frequency levels of supplemental soil aeration. The aeration volumes (V) were 0, 0.5, 1, and 1.5 times (CK, V 1 , V 2 , and V 3 , respectively) the estimated porosity of the plot rhizosphere. Burial depths (D) of subsurface tubing were 15 and 40 cm (D 15 and D 40 ). Aeration frequencies (F) levels were none and at 2-and 4-d intervals (CK, F 2 , and F 4 ). The results demonstrated that aeration frequency and volume positively affected soil urease, phosphatase, and catalase activity and soil microbial abundance. The impact of aeration treatment on rhizosphere soil enzyme activity was greater than its impact on non-rhizosphere activity. When the drip irrigation tube depth was 15 cm, V 2 volume with 2-d aeration intervals led to an increase in the mean yield of first picking fruit of 75.1% compared with the unaerated control. When V 3 volume with 2-d aeration intervals was performed with a 40-cm irrigation tube, the mean yields of the first picking fruit increased by 135.5% compared with the unaerated control. These results suggest that artificial soil aeration can improve the plant root zone environment, increase microbial abundance and soil enzyme activity, and promote nutrient uptake, thus promoting plant growth and fruit output. S oil microorganisms and soil enzymes are important components of agricultural ecosystems. Bacteria, fungi, and actinomycetes play important roles, including decomposing organic matter, degrading cellulose, and forming antibiotic substances. Nitrogen-fixing bacteria provide nitrogen sources for plants, whereas nitrobacteria prevent the accumulation of nitrite in the soil (Clarholm, 1985). Fungi are involved in the soil carbon cycle by decomposing cellulose, lignin, and pectin to release nutrients, and the development of the mycelium improves the physical structure of the soil (Tedersoo et al., 2014 Core Ideas• Rhizosphere soil enzymes activity showed an initial increase followed by a decrease.• soil aeration can enhance the activities of three rhizosphere soil enzymes.• Aeration frequency and volume can significantly affect rhizosphere enzyme activities.• Aeration can enhance the activities of non-rhizosphere soil enzymes.• soil aeration can increase tomato yield.

“…Muskmelon and tomato plant roots are especially vulnerable to Hypoxia stress O 2 deficiency in the soil reduces adenosine triphosphate (ATP) production leading to lower uptake and transport of nutrients to the shoot leading to a reduction in leaf growth and photosynthesis [32]. The results of this study on muskmelon add new information to the findings of Bhattarai et al [18,[33][34][35] and Sharma et al [36] that show positive effects of soil aeration on growth and yield of other crops.…”

Background: Hypoxia causes injury and yield loss. Soil aeration has been reported to accelerate the growth of plants and increase crop yield. The aim of this study was to examine growth response of greenhouse-produced muskmelon to 3 levels of sub-surface drip irrigation (I), 3 different installation depths of drip laterals in the soil (D), and 4 levels of supplemental soil aeration frequency (A). A fractional factorial experiment was designed to examine these treatment effects on marketable fresh fruit yield, leaf area index during 3 growth stages, and dry matter partitioning at harvest. In addition, we studied the response of fruit yield and dry matter of tomato to 2 levels of burial depths of subsurface tubing in combination with 3 frequency levels of soil aeration. Results: Results showed that soil aeration can positively influence the yield, leaf area index, dry matter and irrigation use efficiency of the muskmelon (p < 0.05). The fruit yield of muskmelon and tomato were increased by 21.5 and 30.8% respectively with 1-d and 2-d aeration intervals compared with the no aeration treatment. Conclusions:The results suggest that soil aeration can positively impact the plant root zone environment and more benefits can be obtained with aeration for both muskmelon and tomato plants.

The Disastrous Effects of Salt Dust Deposition on Cotton Leaf Photosynthesis and the Cell Physiological Properties in the Ebinur Basin in Northwest China

Salt dust in rump lake areas in arid regions has long been considered an extreme stressor for both native plants and crops. In recent years, research on the harmful effects of salt dust on native plants has been published by many scholars, but the effect on crops has been little studied. In this work, in order to determine the impact of salt dust storms on cotton, we simulated salt dust exposure of cotton leaves in Ebinur Basin in Northwest China, and measured the particle sizes and salt ions in the dust, and the photosynthesis, the structure and the cell physiological properties of the cotton leaves. (1) Analysis found that the salt ions and particle sizes in the salt dust used in the experiments were consistent with the natural salt dust and modeled the salt dust deposition on cotton leaves in this region. (2) The main salt cations on the surface and inside the cotton leaves were Na+, Ca2+, Cl- and SO4 2-, while the amounts of CO3 - and HCO3 - were low. From the analysis, we can order the quantity of the salt cations and anions ions present on the surface and inside the cotton leaves as Na+>Ca2+>Mg2+>K+ and Cl->SO4 2->HCO3 ->CO3 -, respectively. Furthermore, the five salt dust treatment groups in terms of the total salt ions on both the surface and inside the cotton leaves were A(500g.m-2)>B(400g.m-2)>C(300g.m-2)>D(200g.m-2)>E(100g.m-2)>F(0g.m-2). (3)The salt dust that landed on the surface of the cotton leaves can significantly influence the photosynthetic traits of Pn, PE, Ci, Ti, Gs, Tr, WUE, Ls, φ, Amax, k and Rady of the cotton leaves. (4)Salt dust can significantly damage the physiological functions of the cotton leaves, resulting in a decrease in leaf chlorophyll and carotenoid content, and increasing cytoplasmic membrane permeability and malondialdehyde (MDA) content by increasing the soluble sugar and proline to adjust for the loss of the cell cytosol. This increases the activity of antioxidant enzymes to eliminate harmful materials, such as the intracellular reactive oxygen and MDA, thus reducing the damage caused by the salt dust and maintaining normal physiological functioning. Overall, this work found that the salt dust deposition was a problem for the crop and the salt dust could significantly influence the physiological and biochemical processes of the cotton leaves. This will eventually damage the leaves and reduce the cotton production, leading to agricultural economic loss. Therefore, attention should be paid to salt dust storms in the Ebinur Basin and efficient measures should be undertaken to protect the environment.
