e098 - Fire X Nitrogen: Interactive Effects in a Prairie-Like Grassland

 

Introduction

 

To determine how the effects of N addition depend on litter accumulation and other factors related to fire suppression, 3 randomly chosen replicates of each N treatment in E002  (Long-Term Nitrogen Deposition During Grassland Succession) have been burned and 3 have been unburned each spring beginning in 1993. All continue receiving N addition. Current work is in all plots in the E002 field are being recorded under experiment number E002.
