“…For example, the immediate response of ODR to precipitation (Fig. a, b) confirms the finding that ODR decreases due to restricted diffusive O 2 transport if the pore space is water‐filled ( Wolińska et al., ; Morales‐Olmedo et al., ). The delayed response of O 2 concentration in soil air to decreasing ODR values (Fig.…”

Oxygen diffusion rate (ODR) and redox potential (E H ) are quantitative indices representing oxygen availability and redox status in soils, which is valuable information for better understanding causes and effects of soil aeration. Because these indices are spatially and temporally highly variable, continuous measurements and adequate numbers of repetitions are essential for accurate in situ monitoring. Here, we present a new, fully automated recording system for in situ measurements where ODR and E H are measured at the same platinum electrode. The conflict between electrode polarization for ODR and the resulting biased E H readings is solved by reducing the polarization time and introducing a recovery interval between two consecutive measurement cycles. The shorter polarization time ensures accurate E H readings. It also results in moderately overestimated ODR readings, but this can be corrected before data analysis. The recovery interval restricts temporal resolution of the E H -ODR data pairs to 8 h. We illustrate the use of the system with measurements in a field experiment in Zü rich, Switzerland. ODR curves at different depths ran roughly parallel to the corresponding curves of O 2 concentration in soil air but ODR was much more sensitive to precipitation. Low ODR was a necessary but not a sufficient condition for declining E H . E H ran parallel to O 2 concentration in soil air rather than to ODR. The fully automated system allows for time series of replicate measurements in multifactorial field studies with reasonable labor requirements. It may be particularly suitable for studies examining the effects of soil tillage, compaction, and irrigation, where structure-related soil properties such as porosity, gas permeability, and soil aeration play a dominant role.

“…The soil should have adequate proportions of water and air in the optimal range for the physiological performance of the plants. This balance may be altered by both natural and anthropic factors (Morales-Olmedo et al, 2015). Human related causes include poor irrigation management and soil compaction, while natural flooding are caused by excessive rain (Irfan et al, 2010).…”

In Cuba the 40,3 % of cultivated lands is located in poorly drained soils, with tendency to increase, compounded by the effects of current climate change, which in this region of Cuba are becoming with more frequency in extreme climatic events such as droughts and floods. The research was developed with the objective of determining the influence of flooding in a Vertisol soil in three phisycal properties in the Cauto River Valley, of the Granma province, Cuba. It was considered the presence or absence of flooding as the principal factor on large plots, each one divided into 30 plots of 48 m 2 , to facilitate take the replicate samples. Two samplings, one at the beginning of the experiment and the other five months later, when the soil flooded concluded. The average of the bulk density, total porosity and aeration porosity values with their standard errors were plotted by bars, while statistically discriminated with the use of the Student t test. It is concluded that prolongated water excess in the soil increased bulk density and makes it significantly decreases the total aeration and porosity, which affects physical fertility of these soils and a decrease of the sugarcane yield, the principal crop in Cuba yet. KEYWORDS:Flooding, soil, physical properties. ALTERACIONES PROVOCADAS EN TRES PROPIEDADES FÍSICAS DE UN SUELO VERTISOL POR EFECTO DE LAS INUNDACIONES EN LA REGIÓN ORIENTAL DE CUBA, CULTIVADO CON CAÑA DE AZÚCAR (Saccharum spp.) RESUMENSe parte del hecho de que en Cuba el 40,3% del área agrícola cultivada se ubica en suelos de mal drenaje, con tendencia al incremento, agravado por los efectos del cambio climático actual, donde en esta región de Cuba son cada vez más frecuentes los eventos climatológicos extremos como sequías e inundaciones. El trabajo se desarrolló con el objetivo de determinar la influencia que ejerce el sobrehumedecimiento del suelo en tres propiedades físicas de un suelo Vertisol del Valle del Río Cauto en la provincia de Granma, Cuba, en el cual se cultiva caña de azúcar. Se consideró el factor presencia-ausencia de sobrehumedecimiento en parcelas grandes, subdividido en 30 parcelas de 48 m 2 , para facilitar la toma de muestras replicadas. Se realizaron dos muestreos, uno al inicio del experimento y el otro a los cinco meses, una vez concluido el sobrehumedecimiento. Los valores promedio de la densidad aparente, porosidad total y porosidad de aireación con sus errores estándar se representaron gráficamente por medio de barras, mientras que se discriminaron estadísticamente con el empleo de la prueba t de student. Se llegó a la conclusión de que el exceso de agua en el suelo incrementa la densidad aparente y hace descender significativamente la porosidad total y de aireación, lo que afecta la fertilidad física de estos suelos, lo que provoca un descenso en los rendimientos agroindustriales de la caña de azúcar, principal cultivo económico en Cuba. Palabras claves: Sobrehumedecimiento, suelo, propiedades físicas.

“…Generally, maintaining a soil with moisture above field capacity for long periods, as with I 110 treatment, leads to a decrease in soil aeration because the pores will be filled with water instead of oxygen and water will block diffusion of gas from the atmosphere to the ground (Chen et al, 2011). This may cause several symptoms in plants, but the cause of plant damage in soils is often questioned and the literature suggests that it is more related to the production of toxic substances than the oxygen deficiency in the roots themselves (Morales-Olmedo, Ortiz, & Sellés, 2015). However, there was no symptom of stress in the I110N8 treatment ( Figure 1D), which may suggest a better acclimatization by the co-limitation between irrigation above field capacity and high nitrogen dose.…”

Ocimum gratissimum L. (clove basil) is an annual herb of the Lamiaceae family, widely cultivated as a plant used in cooking and medicine worldwide. There is no information on the visual symptoms of the effects of greater or lesser water irrigation and nitrogen fertilization on the leaves of this species. There is no information on the visual symptoms of the effects of greater or lesser water irrigation and nitrogen fertilization (N) on the leaves of this species. The effects of different water application rates, 60% (I60), 70% (I70), 80% (I80), 90% (I90), 100% (I100) and 110% (I110) of field capacity (FC), and nitrogen fertilization, 0 (N0), 40 (N2), 80 (N4) and 160 (N8) kg of nitrogen/ha, on the leaves of this species were studied. The experiment was carried out for 60 days in a greenhouse in a completely randomised design with three replicates. Water stress was determinant for the appearance of leaves with wilted and stains. Symptoms of necrosis, apical necrosis, abscission and chlorosis were correlated only with N stress. This study suggests that the leaves of Ocimum gratissimum present better acclimatization with irrigation above the field capacity associated with high dose of N (I110N8) and that satisfactorily support the reduction of up to 70% FC with the use of 40 kg of N/ha in their production without presenting any visual symptoms.
