Effect of ladle slag from steel recycling on soil fertility and plant growth

Long-term field experiment on the effect of ladle slag on soil fertility and plant growth

Description

The ZHAW conducts a four-year field trial with simplified crop rotation to investigate the effect of ladle slag on various parameters of soil fertility and plant growth. Ladle slag contains various nutrients and has a calcifying effect, which could be used to stabilize or increase the soil pH. The effect of three treatments is compared: application of ladle slag, application of a comparable agricultural lime product and untreated reference.
