“…Lowered soil aeration during these infiltration and postinfiltration periods can have an adverse effect on the growth and development of plant roots and shoots (Greenway et al, 2006;Heuberger et al, 2001;Niu et al, 2011;Vyrlas and Sakellariou-Makrantonaki, 2005). It has been shown that oxygen deficiency in the rhizosphere soil decreases the growth rate of roots, reduces nutrient and water uptake and significantly lowers crop yields (Chong et al, 2004;Pezeshki et al, 1993).…”

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.

“…The soil oxygen is consumed by root and soil microorganism respiration, which can result in the accumulation of carbon dioxide and hypoxia in the soil pore space. Heuberger et al (2001) suggested that the plant rhizosphere gas is forcibly eliminated after irrigation or rainfall, resulting in a shortage of soil oxygen, which inhibits crop root aerobic respiration, crop growth and development. The soil oxygen and carbon dioxide concentrations influence plant growth and crop yields by influencing plant root growth (Nakano2007; Chong et al 2004;Vartapetian and Jackson 1997).…”

The peach tree root respiration rate is high, which requires large amounts of oxygen. When the rhizosphere oxygen content is poor, the root respiration and energy metabolism are restrained which will have negative impacts on peach trees growth, fruit quality and yield, especially during high temperature and rainy season. Our objectives were to investigate the relationship between rhizosphere ventilation and orchard soil enzyme activity, nutrient status, root architecture and growth of young peach trees. Two-year-old 'Chunmei' peach (Prunus persica L. Batsch) was subjected to various treatments (Treatment 1 [T1]: ventilation every three days; T2: ventilation every six days; T3: natural ventilation; Control: no ventilation) under field cultivation conditions. The soil oxygen content decreased and subsequently increased during the growth period, reaching a minimum in August. The rhizosphere soil oxygen content was higher under ventilation treatment than control, and T1 markedly increased the rhizosphere soil oxygen content. The rhizosphere soil available K and organic matter decreased while the rhizosphere soil available N and available P content increased and the soil enzyme activity was improved under ventilation treatments. The root activity and root nitrate reductase activity increased under ventilation treatments. Under T1, the total root surface area, total root length and number of first lateral root and second lateral root were increased significantly, but the average root diameter and the average length of first lateral root was reduced significantly, the branching angle between first lateral root and vertically downward direction was decreased, the number of small angle was increased. T1improved leaf functions and increased the net photosynthetic rate. Under T1, the leaf chlorophyll content and leaf protective enzyme activity (Superoxide dismutase, Guaiacol peroxidase and Catalase) increased markedly in the middle-and late-growth period and leaf senescence was postponed. The total nitrogen, phosphorus and potassium contents of young peach roots, shoots and leaves, as well as shoot growth, leaf weight and leaf area, increased under T1.

“…One of these problems is the inadequate air in the root zone due to irrigation. During and following irrigation events, air in the soil pore space is replaced by water, resulting in poor soil air around crop roots (Poysa et al, 1987;Heuberger et al, 2001;Chen et al, 2009). The occurrence of soil air displaced by irrigated water often results in the temporal decrease of O^ levels in wetted soil.…”

While subsurface drip irrigation supplies water to meet crop needs with high water use efficiency, it might cause low O2 levels around crop roots and affect plant growth and yield. A modified flow apparatus was used in the laboratory to investigate the impact of aeration following subsurface drip irrigation on transient air permeability. Disturbed samples from two soils from China, a Brown Forest soil (sandy loam) and Lou soil (silty clay loam), were repacked to construct soil columns with various bulk densities (1.3, 1.35, 1.4, 1.45, 1.5, and 1.55 g cm−3). Subsurface drip irrigation (350 mL) was performed at the 17‐cm soil depth. Aeration (1050 mL) was conducted through the emitter of the subsurface drip irrigation system for 5 min. The results showed that air permeability was affected by soil texture and bulk density. The measured air permeability from the modified apparatus was comparable to that from the classical apparatus. Soil air permeability after irrigation was reduced by 88.2, 70.1, and 42.5% for the Brown Forest soil with a bulk density of 1.3, 1.4, and 1.5 g cm−3, respectively, and 71.2, 65.4, and 54.3%, respectively, for the Lou soil. A short‐period aeration following irrigation quickly improved soil air permeability, however. The air permeability level within 10 min after aeration was 3.7, 2.0, and 1.5 times that before aeration for the Brown Forest soil with a bulk density of 1.3, 1.4, and 1.5 g cm−3, respectively, and 3.0, 2.5 and 2.0 times, respectively, for the Lou soil. It seems a feasible and economical approach to improve soil air permeability by aerating the soil through a subsurface irrigation system following irrigation.
