1. Respiration as a Measure of Soil Health: Challenges and OpportunitiesIn recent years, respiration has become a commonly-used soil health metric. It has been used as a standalone predictor of soil N supplying capacity and in conjunction with other metrics to assess overall soil health. However, the sources of variation underlying respiration itself have not been thoroughly assessed. We show that across growing regions in California, respiration was unable to accurately predict soil N supply. The R2 values were much higher in fields that had received a recently-incorporated... J.

2. FRST Lime Project: Results of Pilot Study of Lime Source, Lime Rate and Incubation Time on Neutralization of Soil AcidityManagement of soil acidity plays a critical role in the agriculture across North Central Region. The Fertilizer Recommendation Support Tool (FRST) group has launched a national project to develop new lime recommendations and has collected 144 soils of which 38 soils from the North Central Region. A pilot lime study was initiated to assess the effect of lime source, lime rate and incubation time on neutralization of soil acidity. Three acid soils were selected from the Agricultural Proficiency... B. Miller |
