# Data of slurry quality, soil chemistry and crop yield and composition from a field experiment established 2011 comparing digested and undigested slurry

## TL;DR

This paper provides data from a long-term study comparing the effects of digested and undigested cow slurry on soil and crop outcomes in Norway.

## Contribution

The study offers a detailed dataset from a 10+ year field experiment comparing digested and undigested slurry effects on soil and crops.

## Key findings

- The dataset includes soil chemistry, crop yield, and plant mineral composition over multiple years.
- Both slurry types were from the same herd, allowing for direct comparison of their agricultural impacts.
- The data supports analysis of long-term effects of anaerobic digestion on soil and crop productivity.

## Abstract

The article presents relevant data from a long-term field experiment in Norway, comparing anaerobically digested and undigested slurry from organically managed dairy cows since 2011. Both the undigested and digested slurry originated from the same herd of cows and heifers. The dataset includes chemical analyses of slurry, soil characteristics at plot level of pH, extractable nutrients, and loss on ignition; crop yields, botanical composition (some years), and plant mineral composition (some years). These data supplement the findings presented and discussed in the research article Anaerobic digestion of dairy cattle slurry – long-term effects on crop yields and chemical soil characteristics[1].
