Gardeners with pot plants, or a sandy garden, are likely to have experienced water repellent or hydrophobic soils. Soils become hydrophobic when they are dry for extended periods - particularly when the dryness is combined with a high organic content.
But these days there are many soil wetting agents on the market intended to help soil absorb water. According to soil scientist, Dr Peter May, there is a simple experiment people can undertake at home to see whether they have hydrophobic soil.
"Take some dry soil and place it in a dish. Make a well in the top and then pour on some water. If the soil is hydrophobic, the water will pool on top. In contrast when you wet soil that is not hydrophobic, the water is quickly absorbed," he said.
The simplest way to improve water take up by hydrophobic soils is to use a soil wetting agent. "We believe that what happens in some soils when organic matter breaks down is that it leaves a waxy coating on the soil particles. Wetting agents are like detergents. They overcome that waxing coating and allow water to penetrate into the pore spaces between," Peter said.
"Most potting mixes, if they become dry, will also become water repellent," he said.
This means that when people say that their plants need watering every day in summer, it might just be the way they are applying water, and the mix isn't taking up moisture.
"It is certainly possible. I think using wetting agents in pots or containers in summer is a good idea," Peter said.
Another different product on the market, designed to help gardeners improve the water holding capacity of their soil, is a water-storing granule or gel. These are small crystals of polymers that are designed to absorb up to four hundred times their weight in water.
"A spoonful of crystals, which is about what you'd put into a pot if you were mixing it in potting mix, will absorb about a litre of water if left overnight," Peter said.
He said the crystals did not save water. "But they increase the water holding capacity of the soil. This means that more water is held for plant use, and that also means plants can go for longer between watering. It will not change the amount of water that a plant uses, but it will last longer between drinks," Peter said.
The crystals don't help with water uptake in hydrophobic soils. "That's a completely different property. The crystals increase the water holding capacity of the soil. But the soil wetting agents overcome hydrophobic soil. It's important to sort out which problem you have got in the garden and specifically treat it," Peter said.
To sum up what Peter has discovered.
* Gardeners with water repellent soil should use a soil wetting agent. It will help with water absorption, particularly if you have sandy soil or pots that are filled with potting mix.* Remember if you want to use a water storing gel, remember, it will eventually dry out. You might get an extra day or two between waterings, but beware of products saying they will save you water, because there is nothing to suggest that they actually have a water conservation value.
* And finally, remember to differentiate between the two products and choose the product that's suitable for your purpose and your soil

Answer:
The water could not absorbed as soil as water repellent because the water will be absorbed in the soil the water should touch the tip of the root if it will be touched the tip of the rule the water with just go away from the down because we cannot see the water the water will be observed by the tip of the root and also the soiled because soil needs water to be keep fresh and the soil would be fresh then the water would goes complete the water till it would be reached to the tip of the root..... so we should want to keep the water fresh and it will be observed by help the soil and it should be released in the tip of the root so the plant grows the seed will germinate this process is called germination......
