Introduction Climate change is one of the big challenges faced by the modern world. In the Middle East, and specifically the UAE, there are humid summers and warm winters which have influenced agriculture production. Biochar has been described as a possible means of improving soil fertility, water holding capacity and sequester carbon (C) to mitigate climate change. Therefore, The aim of this project is to test date palm frond and biochar as a means of enhancing water holding capacity in UAE soils 3. Results First cycle Date Palm Frond (DPF) control and 15% DPF had the highest moisture concentration during the first cycle (figure 2). 1% Biochar showed the highest plant growth during both wet and dry cycles (figure 2 and 3). Second cycle 15 % Biochar managed to retain water longer comparing the controls and other treatments (figure 4 and 5). Plant growth increased after it was covered where it mostly showed in two pots: the 18% Biochar and 1% DPF (figure 5). 2. Methodology Date palm frond (DPF) waste (figure 6) and sandy soil were collected from Abu Dhabi, UAE. The DPF samples were sent to the lab (Durham University, UK) and cut into small pieces (figure 7) then charred at 250 ° C for 4 hours and 1 hour cooling. Hydro-physical properties were analysed using two experimental pot trials: First cycle was based in the lab (Durham University (figures 8- 10) and the second cycle was based at a residential garden in Abu Dhabi, UAE (figures 11-14). The pots were irrigated on a daily basis (during the wet cycle) and monitored its height, pH, moisture, humidity, temperature and light using both roller and moisture probe (figure 1). The experiment was a complete factorial with respect to the following factors: the controls (Sharp sand, DPF and Biochar) and treatments for both Biochar and DPF concentrations (1%, 6%, %15 and 18%) (figures 2-5). 6. Conclusion This would indicate that there is good potential for DPF in retaining water. Water concentrations in the soil are similar for both DPF and Biochar, suggesting a reduced need for biochar production. 4.

1. IntroductionClimate change is one of the big challenges faced by the modern world. In the Middle East, and specifically the UAE, there are humid

summers and warm winters which have influenced agriculture production. Biochar has been described as a possible means of improving soil fertility, water holding capacity and sequester carbon (C) to mitigate climate change. Therefore,

and dry cycles (figure 2 and 3).• Second cycle• 15 % Biochar managed to retain water longer comparing the

controls and other treatments (figure 4 and 5).• Plant growth increased after it was covered where it mostly

showed in two pots: the 18% Biochar and 1% DPF (figure 5).

2. Methodology• Date palm frond (DPF) waste (figure 6) and sandy soil were

collected from Abu Dhabi, UAE.• The DPF samples were sent to the lab (Durham University, UK)

and cut into small pieces (figure 7) then charred at 250 ° C for 4hours and 1 hour cooling.
