求翻译：将吸水树脂施用于土壤，加水后土壤体积明显增加。20g土中加入0.12g吸水树脂，体积膨胀率可达20.8%，实验发现随着吸水树脂使用量增加，土壤体积膨胀率也增大。是什么意思？

Absorbent resin applied to the soil, add water to the soil volume increased significantly. 20g soil by adding 0.12g absorbent resin, the volume expansion rate of up to 20.8%, was found to increase the amount of resin used as the absorbent, soil volume expansion also increases.

Facilities will be used in soil, water-absorbing resin soil volume increased significantly after the addition of water. Added to 20 g and 0.12 G and the volume is dropping water absorption resin can be found in the experimental with 20.8 per cent growth in the use of water-absorbing resin soil volum

Absorbent resin employment in soil, after watering soil volume obvious increase.In the 20g earth joins the 0.12g absorbent resin, the volume expansion rate may reach 20.8%, the experiment discovered increases along with the absorbent resin amount of use, the soil volume expansion rate also increases

Water-absorbing resin applied to soil, soil and water volume increased significantly. Add 0.12g in 20G soil water-absorbent resin, blow up 20.8%, experiment found with water-absorbent resin using increased soil volumetric expansion ratio increases.
