Environment Ministry's New Irrigation Method Ups Date Fruit Weight By 26%

The Ministry of Environment, Water, and Agriculture has introduced an innovative irrigation method using fish farming wastewater, significantly enhancing date palm productivity in Saudi Arabia. This approach has shown a notable impact on soil nutrient levels and various date characteristics, boosting their economic value.

Research conducted by a specialised team titled "The Impact of Using Fish Farm Wastewater on Palm Production" reveals that this method is a pioneering step in sustainable agriculture. The organic matter and nutrients, especially ammonia from fish food residues and waste, improve soil health and increase crop yield.

Date palms irrigated with fish farming water showed a 26% increase in fruit weight, a 17% gain in length, and a 13% increase in diameter. Additionally, the nutrient levels in the dates rose significantly: sugar content by 25%, zinc by 367%, manganese by 112%, copper by 9%, calcium by 15%, phosphorus by 42%, and iron by 162%.

The study highlights the economic benefits of using fish farming wastewater for irrigation. These include improved nitrogen and organic matter levels in the soil, reduced dependence on manufactured mineral fertilizers, conservation of water resources, increased farmer income, and promotion of the circular economy.

This research supports a national initiative to expand applied agricultural research, which is a key part of Saudi Arabia's transformation strategy. The study estimates that the Kingdom's 362 fish farms produce around 386 million cubic meters of wastewater annually.

Alignment with Vision 2030

The strategic use of this wastewater for irrigating date palms can greatly enhance local date production and quality. This aligns with the goals outlined in Vision 2030 to promote sustainable agricultural practices.

Furthermore, the study underscores the potential for this method to contribute to sustainable agriculture by improving soil health and increasing crop yields. This innovative approach not only boosts productivity but also supports environmental conservation efforts.

The findings demonstrate that using fish farming wastewater is an effective way to enhance date palm productivity while promoting sustainability. This method offers a viable solution to improve agricultural practices in line with national goals.
