In the return liquid of water and fertilizer, there are still a large number of ionized mineral elements that have not been absorbed by the plant. These elements are discharged into the natural environment and become an important pollution source to affect soil and water. Long time ago, developed countries already have paid attention to the pollution impact of water and fertilizer discharge on the environment and take it as the main problem to work with, so they use rock wool as the main substrates because it has less circulating irrigation and less discharge. By using UPuper® Rockwool cubes, the return liquid can be clearer. And the excess water and fertilizer will flow into the diversion tank and return to the irrigation system. After disinfection, it can be 100% recycled, which can not only avoid the waste of water and fertilizer, but also avoid environmental pollution due to informal discharge, especially stop the causing and aggravating the eutrophication of water.

Soil provides living space and important eco system for human, it can store and filter water, intercept pollutants from penetrating into groundwater; but more importantly, soil is a non renewable resource, which is very difficult to repair once it get polluted. In the brief of national soil pollution survey published in 2014, the point exceeding standard rates of eight inorganic pollutants of heavy metals cadmium, mercury, arsenic, copper, lead, chromium, zinc and nickel were 7.0%, 1.6%, 2.7%, 2.1%, 1.5%, 1.1%, 0.9% and 4.8% respectively. In traditional soil planting, there is a large amount of pesticides and fertilizer applying to the plants, which destroys the soil structure and ecological balance, kills the organic organisms in the soil. Those lead to the imbalance and loss of organic matter. UPuper® rock wool is the represent of new soilless cultivation mode. It does not need to worry about soil salinization, hardening or borne diseases etc. It helps to solve the continuous cropping obstacles and protect soil resources from the origin. If soilless cultivation technology is used for plant cultivation, it can not only reduce its burden on the soil, but also give it an effective period for self recovery.
