The research aims to study the effect of adding sodium polyacrylate (extracted from children's diapers) to soil properties, and their importance in reducing water consumption and maintaining soil moisture. The study also aims to investigate the effect of adding material to the soil on the growth of plants, such as barley, rose, and onion, in the Al Mulaqa area, Al Buraimi Governorate. The researcher used the experimental approach to study soil properties through the application of the environmental GLOBE program: the soil protocol, as well as the application of a water protocol to measure the properties of water used for irrigation in these areas (oxygen ratio, salinity, conductivity, and pH). And fixing the following factors: the quality of water and soil, the amount of water and light. A vegetation protocol was applied to note the effect of this on cultivated plants (barley, onion, rose) by taking a plant length measurement on a weekly basis for two months, and by observing the color and number of leaves of the plant. The results showed that sodium polyacrylate increases the ability of the soil to retain water and maintain mineral salts and nutrient oxides, and improves the pH appropriately (ph=6-6.5) which in turn helps the plant absorb iron and minerals and eliminate microbes, which makes the plant Capable of growing in dry areas with high quality. Therefore, the current study recommends the concerned authorities to apply the idea and take advantage of the disposable diapers to be converted into a fertilizer containing sodium polyacrylate for use in dry areas. As well as cooperating with the concerned authorities and the STEM team to prepare natural polymers in various technology methods such as electric yarn technology to treat the problem of water scarcity.

Dear Aisha Hassan Salem Hassan Al-Suraihi,
I really enjoyed reading your IVSS project. It was a very well designed experiment using many GLOBE soil and hydrology protocols. I have some questions that would love to hear your answers.
(1) how many replicates did you use per treatment? (how many barley pots that you use for the experimental and control set).
(2) how many grams of sodium polyacrylate did you put it in each experiment? Did you put the same amount of sodium polyacrylate in each pot?
(3) You concluded that after adding the sodium polyacrylate in soil, soil pH decreased. This is correct but you used the wrong results to compare in your report. You used soil pH comparing water pH.
Keep up your great work.
