The Benefit of Using Drainage Water of Fish Farms for Irrigation: Field and Modelling Study Using the SALTMED Model

Abstract

This study investigated the suitability and benefits of using drainage water of fish farms (DWFF), instead of canal fresh water (IW), for wheat irrigation. Two water qualities, DWFF and IW, and four levels of N‐fertigation rates [100% N (192 kg N ha−1 season−1), 80% N, 60% N and 40% N] were tested. The results showed a positive impact when increasing N‐fertigation rate on the yield using both DWFF and IW. However, the yield under DWFF was higher than the yield under the IW treatment by between 11 and 51% in 2014 and between 8 and 38% in 2015. This is due to the additional amount of dissolved biological nitrogen and other nutrients inherent in DWFF. The SALTMED model simulated reasonably well the soil moisture and nitrogen content of all soil layers as well as wheat dry matter, yield and water productivity for all treatments, with R2 of 0.99, 0.97 and 0.96, respectively. It was concluded that the use of drainage water of fish farms instead of fresh water for irrigation of wheat could help to achieve higher yields while using less irrigation water and less chemical fertilizers. Additional benefits are less drainage to the drainage network and higher income for farmers. Copyright © 2017 John Wiley & Sons, Ltd.

The Influence of Gibberellic Acid and Different Irrigation Resources on Morphological, Quality and Yield Parameters of some Sweet Sorghum Varieties in New Reclaimed Area

“…These findings may be due to the additional amount of dissolved biological nitrogen and other nutrients inherent in waste water of fish farm. These results are in accordance with those obtained by Abdelraouf and Ragab (2017) how found that the yield under waste water of fish farm was higher than the yield under well ground water.…”

“…A Reuse waste water of fish farming as a new resource for irrigation and rich with organic matter can improve soil quality and crops productivity and reduce the total costs of fertilizers by adding minimum doses from mineral fertilizers and reduce the pollution in soil. Abdelraouf and Ragab (2017) found that the yield under waste water of fish farm (WWFF) was higher than the yield under the canal fresh water (IW) by 11 and 51% in 2014 and 8 and 38% in 2015 seasons.…”

Effect of Fish Farm Waste Water Irrigation and Growth Regulators on Growth, Yield and Quality of Sugar Beet Crop

“…These results are in accordance with these obtained by (Elnwishy et al, 2006) who stated that, recycling the drainage water of fish farming, rich with organic matter for agriculture use can improve soil quality and crops productivity. In addition, Abdelraouf and Ragab (2017) found that the yield under waste water of fish farm was higher than the yield under well ground water. On the other hand, Gibberellic acid has the ability of effect on yield by modifying the growth pattern by affecting the cell elongation and cell division, biosynthesis of enzymes, protein, and carbohydrates contents (Gupta andChakrabarty, 2013 andMilne et al, 2013).…”

Fishpond Water Potential on Vineyard Soil Health: An Exploratory Study of a Circular System

“…The study results reveal that watering with fishpond water for almost two decades has positively affected grape yields compared to irrigating with just ditchwater (Figure 2), which is consistent with similar studies from other locations and systems. In different studies, fishpond water increased paddy rice [21,22,28] and wheat [29] yields. The positive yield effects from fishponds relate to soil fertility and health improvements, as observed by others [28,29], which is also consistent with the findings of this study.…”
