Saving 45% of Irrigation Water of Date Palm Tree Plantations Using Soil Amendments in UAE | .....

In Arab countries, the date palm (Phoenix dactylifera) can withstand relatively hard climatic and soil conditions. In Arab locations, the annual total irrigation water requirements for Date palm trees varies from 73.0 to 95 (m3/tree). Furthermore, the agricultural sector consumes roughly 70-80 percent of global freshwater, although water use efficiency in many nations is below 50 percent. Currently, 2.8 billion people live in water-stressed areas, but by 2030, it is predicted that half of the world's population would be living in such places. Water saving additives are natural soil mixes made from recycled date palm fronds and farm waste to make compost and bio char, which can be used to minimise the amount of water required in date palm irrigation. When soil supplements are put into the soil, the material may hold a lot of water per kg of product, making it a good water reservoir, especially during droughts. We employed three natural diverse water conserving materials to evaluate their impact on saving irrigation water under date palm plantations in this experiment. The Three different water conserving products e.g. compost, Bio Char (BC), and water conserving goods e.g. (WS). There were five different levels of water-saving materials employed, including control, 5 kg/tree, 10 kg/tree, 15 kg/tree, and 20 kg/tree. According to our findings, adding 15 kg of water-saving additives per tree can lower the amount of water required for irrigation by 45 percent. This study report focuses on employing soil conditioning and water-saving modifications to introduce natural ways of regulating irrigation water. We calculated the economic value of water saved and discovered that compost and bio char can save 6.35 m3/tree and 11.35 m3/tree of water per year, respectively, while the water saver product can save 31.90 m3/tree per year. Compost and bio char can save 5.40$ and 9.65$ per tree per year, respectively, while water saver products can save 27.13$ per tree per year. As a result, soil conditioning with these materials can save a lot of water in the agricultural sector, including date palms and other plants, while also improving soil qualities. This research was carried out to demonstrate how much water can be saved when farmers recycle farm wastes as soil conditioners, as well as the influence on farm profitability and environmental preservation.
