| Abstract: | The loss of phosphorus(P) leaching from substrate soilless culture systems will not only lead to a decrease in the utilization ratio of fertilizers and an increase cost of horticultural production, but also give rise to the eutrophication of surface water and ground water bodies. Based on integrated relevant literature, this paper elaborates the outset of the problems, the affecting factors of P-leaching and the prevention and cure method. Practical and innovative measures will be employed for the control of horticultural P-leaching to water. |
