“…In the present study, aeration volume and aeration frequency significantly increased tomato yield (Fig. 6), consistent with previous studies that reported that improving of the soil air condition can increase crop yield (Bonachela et al, 2010;Ityel et al, 2014;Niu et al, 2012aNiu et al, , 2012bNiu et al, , 2013Shahien et al, 2014). Artificial soil aeration improved crop root growth environment and nutrient uptake in the roots, thus promoting plant growth and increasing yield.…”

“…Hypoxic stress can negatively affect crops in at least two ways: (i) the activities of soil animals and aerobic microorganisms are slowed and soil enzyme activity is reduced, thereby reducing soil fertility (Drew, 1992(Drew, , 1997Qiu et al, 2004), and (ii) the insufficient oxygen supply to plant roots negatively affects physiological functions (Niu et al, 2012a). Hypoxic stress causes an accumulation of leaf abscisic acid, which reduces stomatal density and opening and inhibits the growth of stems and leaves, resulting in a reduced net photosynthesis rate, slower plant growth, reduced accumulation of dry matter, and limited yield and quality improvement (Munns and Sharp, 1993).…”

“…Our previous studies have also shown that artificial soil aeration can improve the tomato (Lycopersicon esculentum Mill.) root zone environment, increase soil enzyme activity, and promote the uptake of nutrients, thus promoting plant growth and fruit output and improving soil quality (Li et al, 2015a;Niu et al, 2012aNiu et al, , 2012b.…”

“…Because the tomato is one of the most sensitive species to water and air in the soil (Bradford and Yang, 1981), the present study used greenhouse tomatoes as its study subject. Higher tomato yields are related to higher oxygen contents in the soil root zone (Meek et al, 1983;Niu et al, 2012aNiu et al, , 2012b. Observed changes in plant growth were mainly because of the changes in nutrient cycling and physiological status, and soil-available nutrients were affected by soil microorganisms and soil enzyme activity.…”

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.

Sensitivity to low rhizosphere soil aeration may change over time and therefore plant response may also depend on different growth stages of a crop. This study quantified effects of soil aeration during 5 different periods, on growth and yield of trickle-irrigated potted single tomato plants. Irrigation levels were 0.6 to 0.7 (low level) or 0.7 to 0.8 (high level) of total water holding capacity of the pots. Soil was aerated by injecting 2.5 l of air into each pot through the drip tubing immediately after irrigation. Fresh fruit yield, above ground plant dry weight, plant height, and leaf area index response to these treatments were measured. For all these 4 response variables, means of post-infiltration aeration between 58 to 85 days after sowing were 13.4, 43.5, 13.7, and 37.7% higher than those for the non-aerated pots, respectively. The results indicated that: post-infiltration soil aeration can positively impact the yield and growth of sub-surface trickle-irrigated potted tomato plants; positive effects on plant growth can be obtained with aeration during the whole growth period or with aeration for partial periods; positive growth effects of partial periods of aeration appears to persist and result in yield benefit.

Soil aeration can enhance soil enzyme activity and plant growth. These effects may be caused by variations in soil microbial diversity and plant root development. However, little is known about the responses of soil microbial composition, structure, and diversity and plant root development to artificial soil aeration. The aims of this study were to examine the composition, structure, and diversity of rhizosphere bacterial communities and tomato root morphology under four aeration volumes in combination with drip‐tubing placed at two different soil depths. The aeration volumes (V) were 0, 0.5, 1, and 1.5 times (CK, V1, V2, and V3, respectively) the standard aeration volume. The drip irrigation tube burial depths were 15 (D15) and 40 cm (D40). The results demonstrated that soil aeration had a significant influence on root performance (root morphology and activity) and soil bacterial diversity in the tomato root zone. In comparison with the CK treatment, V3 soil aeration increased root length, surface area, tip number, and activity by 7.9%, 6.3%, 14.5%, and 7.0%, respectively. The abundance‐based coverage estimator, Chao index, and Shannon diversity increased by 5.3%, 4.7%, and 3.5%, respectively. The abundance of Acidobacteria increased and that of Gammaproteobacteria decreased in response to the soil aeration treatments; conversely, Geobacteraceae and Halanaerobiaceae were eliminated. Moreover, different subsurface tubing placement depths changed the rhizosphere bacterial community. The results indicate that soil aeration ameliorates hypoxic conditions and provides benefits to soil bacterial communities and root morphology.
