“…[N] for the both treatments decreased from approximately 40 mg g −1 to 20 mg g −1 with plant growth. This decline was also observed in previous studies (Peng et al 2010;Yasutake et al 2014a). There was no significant difference in the values for [N] between the two types of treatment; this means that the flooding had no effect on [N].…”

“…Since the nutrient salt uptake by roots is closely related to transpirational water flow (Kitano et al 2007;Sago et al 2011 analyzed evapotranspiration and its components in catch crop fields, and observed an extremely high transpiration rate induced by high leaf area index (LAI ) with dense planting. Yasutake et al (2014a) then found a linear relationship between the nutrient salt uptake rate and the transpiration rate on a weekly basis, and suggested the importance of management practices to induce larger transpiration. Kondo et al (2013) studied seasonal changes in the performance of catch crop cultivation coupled with flooding, and reported a 89-91% reduction in nitrogen leaching, and a 68-89% reduction in N 2 O gas emission during summer.…”

Advantages of pre-harvest temporal flooding in a catch crop field in relation to soil moisture and nutrient salt removal by root uptake

Catch crop cultivation coupled with subsequent flood activity is an environmental friendly method of removing nutrient salts from soil in greenhouse. However, in comparison with the usual fallow period in greenhouse horticulture in Japan, a longer time is required for cultivation and soil drying after flooding. To minimize such time while retaining catch crop performance, temporal flooding was conducted in an experimental catch crop field of corn before harvest (i.e., pre-harvest temporal flooding), when crops were growing well and most nutrient salts within the soil had been taken up by the roots. Results showed that pre-harvest temporal flooding enhanced crop growth and stomatal opening; hence, evapotranspiration (mostly transpiration) was increased to a high value (3.5 times that of bare soil plot in greenhouse). Therefore, compared with the bare soil field, there was a remarkable pronounced decrease in the soil water content due to evapotranspirational water loss in the catch crop field after temporal flooding. Furthermore, the total nutrient (nitrogen) uptake by crops was also significantly accelerated in relation to pre-harvest flooding owing to the increase in crop growth. It was also found that electrical conductivity and nitrate nitrogen concentration of soil solution (at a soil-water ratio of 1:5) decreased with time owing to root uptake, and were at a fairly low level when pre-harvest flooding was conducted. These results suggest that pre-harvest temporal flooding shortens the implementation time by accelerating soil drying, and increases salt removal by root uptake; thus, this method delivers considerable advantages for practical use in catch crop cultivation.

“…Therefore, it is important to select the adequate plant density by considering not only the total N removal but also the water use efficiencies for growth and N removal, and other agrophysical and physiological parameters. We have previously analyzed how the dynamics of growth, evapotranspiration and its components (transpiration and evaporation), and nutrient salt (N and others) uptake in catch crop fields are affected by plant density (Yasutake et al, 2011(Yasutake et al, , 2014b. However, the interactions among these processes were not fully understood in either in our previous studies (Kondo et al, 2013;Yasutake et al, 2011Yasutake et al, , 2014aYasutake et al, , 2014b or other related studies using catch crops (Min et al, 2011;Rinnofner et al, 2008).…”

“…This analytical methodology was applied to the data obtained from a greenhouse cultivation experiment (Yasutake et al, 2014b) in which corn was used as the catch crop and was cultivated at three different plant densities. The goals of this study were as follows: -to analyze the comprehensive mechanisms underlying the effect of plant density on N removal in relation to crop growth and water use and -to examine the effectiveness of our newly proposed analytical methodology in the agrophysical context.…”

A b s t r a c t. A new methodology for comprehensive analysis of the characteristics of nitrogen (N) removal from greenhouse soil by catch crop was proposed in relation to its growth and water use. The N removal is expressed as the product of five parameters: net assimilation rate, specific leaf area, shoot dry weight, water use efficiency for N removal, and water requirement for growth. This methodology was applied to the data of a greenhouse experiment where corn was cultivated under three plant densities. We analyzed the effect of plant density and examined the effectiveness of the methodology. Higher plant densities are advantageous not only for total N removal but also for water use efficiency in N removal and growth because of the large specific leaf area, shoot dry weight, and decreased soil evaporation. On the other hand, significant positive or negative linear relationships were found between all five parameters and N removal. This should improve the understanding of the N removal mechanisms and the interactions among its components. We show the effectiveness of our analytical methodology, which can contribute to identifying the optimum plant density according to the field situations (available water amount, soil N quantity to be removed) for practical catch crop cultivation.
