“…It has been demonstrated that the physiological effects of flooding on most plants include decreased uptake and transport of ions through roots (Stiepniewski and Przywara 1992). Our results showed that root hypoxia had selective effects on potassium, magnesium and calcium content.…”

The decrease in growth rate of the root system, or the complete cessation of its growth, in fruiting tomato plants is a known phenomena. It has been suggested that a limited supply of carbohydrates to this organ, because of its relative weakness in competition with the developing fruitlets is the main cause for these disorders. This hypothesis was tested in this study with tomato plants (Solanum lycopersicum cv Micro‐Tom) submitted to gradual root hypoxia (1–2 % oxygen) at first flower anthesis and with limited fruit number (six fruits per plant). To this end, a range of physiological and biochemical parameters was evaluated. Our results showed that under oxygen deficiency, root growth was severely affected. In contrast to fruits, root protein and carbohydrate contents decreased significantly, concomitantly with a significant decrease in photosynthesis. Together the present data revealed that, at the fruiting stage, the effect of flooding on root growth and metabolism is probably controlled by the relative sink strength of the fruit.

“…Under wet conditions the air permeability of a clay soil was found to be greater vertically than in the horizontal direction, which can be explained by the presence of vertically oriented biopores 54 . As a result, elevated oxygen concentrations in biopores may have an effect on microbial activity and nutrient uptake by roots limited by a lack of oxygen in a dense subsoil 55 , 56 .…”

The living soil is the basis for crop production in organic agriculture. Biopores are voids in the soil which were formed by the activity of soil life. The first scientific studies on biopores were published in the 1870s–90s by Victor Hensen who stated that earthworms were opening channels to the subsoil and coating them with humus, thus creating a beneficial environment for root growth. His work was originally widely recognized, but then research on biopores was neglected for many decades and was only revitalized with the rise of ecological concerns in the 1960s. In recent times, biopores have attracted the attention of agronomists with a focus on organic agriculture. New visualization techniques, such as X-ray micro computed tomography, in-situ endoscopy and nuclear magnetic resonance imaging have been applied. Biopores contribute to air transport through the soil, increase water infiltration, reduce water runoff and soil erosion, serve as preferential pathways for root elongation and can facilitate the acquisition of water and nutrients from the subsoil. The relevance of biopores for nutrient acquisition can be pronounced particularly in organic production systems, where crops are more dependent on nutrient acquisition from the solid soil phase than under conditions of conventional agriculture. Organic land-use strategies should aim to increase number, stability and quality of biopores. The biopore density can be increased by the share of dicotyledons in the crop rotation and by cultivating perennial crops with taproot systems. Moreover, density and—in particular—the quality of biopores, e.g., the nutrient contents of pore walls, can be influenced by anecic earthworms which can be promoted by adapted tillage practices.

“…Physiological effects of waterlogging include a decrease in uptake and transport of ions through roots (Drew and Sisiworo, 1979); thus, plants may suffer from nutrient deficiency in waterlogged soils. Reduced concentrations of nutrients in shoots due to waterlogging have been reported in various plant species (Pezeshki, 1994;Stepniewski and Przywara, 1992;Trought and Drew, 1980). Increased soil nutrient supply can modify plant responses to waterlogging.…”

Nutrient accumulation and distribution of wheat genotypes in response to waterlogging and nutrient supply

et al. 1995

The effect of soil waterlogging and nutrient supply on plant nutrient accumulation and distribution was investigated for two genotypes of winter wheat (Triticum aestivum L.) differing in waterlogging resistance, 'Bayles' and 'Savannah'. Plants were grown in waterlogged or drained sand and fertilized with half-strength or full-strength Hoagland's solution.Waterlogging reduced the concentrations of N, P, K, Mg, and Zn in leaves and stems and increased the concentrations of those elements in the root system. The effects were greater for waterlogging-sensitive Bayles than for waterlogging-resistant Savannah. Higher concentrations of Fe and Mn were found in waterlogged plants compared to the control plants for sensitive Bayles. Waterlogging increased the proportion of N and Zn in the root system and decreased that of K in stems for Bayles. The proportion of Fe increased in leaves and stems for Bayles and Savannah under waterlogged conditions, but to a greater extent for Bayles. Doubling the concentrations of all major and minor nutrient elements supplied to the waterlogged rooting medium improved plant nutrient status and enhanced plant dry matter production.
