Abstract

Soil health metrics in agricultural systems require edaphic context, notably climate, soil type (soil texture and classification), as well as cropping system. Soil samples (n=1,334) from New York State (USA) with both texture and cropping system information were analyzed for eight physical and biological soil health indicators (soil organic matter, permanganate-oxidizable carbon, respiration, protein, available water capacity, wet aggregate stability, and penetration resistance from 0-15 and 15-45 cm), and population distribution functions were determined. Production environment soil health (PESH) goals were derived for four soil texture groups and six cropping systems by proposing the 75th and 90th percentile for each factorial class. Finer-textured soils and Pasture and Mixed Vegetable systems generally have higher values for soil health goals followed by Dairy Crop and Orchard systems, then Annual Grain, and Processing Vegetable systems. A comparison between Long Island and the rest of New York State demonstrated that soil organic matter PESH goals for Long Island were on average 0.8 % lower than those from the rest of the state. This indicates that regional PESH goals within a state or region may be warranted if edaphic context is considerably different.
