Study on fertilization techniques for greenhouse vegetable in Shanghai suburbs

The establishment vegetable land in Shanghai extended quickly in recent years, it has covered over 6,670 hectares in 2009. However, with the continue and high intensive vegetable planting, the issues of soil fertility degradation such as soil secondary salinization and soil acidification become more and more serious in recent years. Therefore, the Environmental Resource Institute of Shanghai Academy of Agricultural Science carried out this project to study the better nutrient management strategy for greenhouse vegetable in Shanghai suburbs since 2010.
