  • Erosion-Productivity Relationships - Washington State University
    The Naff soil typically has a relatively shallow, silt loam topsoil over a heavier, silty clay loam subsoil (argillic horizon) Compared to the topsoil, the clayey subsoil reduces water infiltration, slows root growth, and generally creates a less desirable seedbed
  • Northern Arizona Forest Fund - National Forest Foundation
    The NAFF’s projects will reduce wildfire and flood risk, improve streams and wetlands, enhance wildlife habitat, restore native plants, and limit erosion and sediment into Arizona streams, rivers, and reservoirs
  • Long-term effects of organic and conventional farming on soil erosion
    higher erosion rate of the conventionally-farmed Naff soil, its surface (Al) horizon thickness was only 3 cm thinner than that of the organically-managed soil
  • Official Series Description - NAFF Series - USDA
    In some pedons, the peds in the upper part of the Bt horizon are coated with light gray very fine sand and silt from a few grains to 1 mm thick 6 2016--This official series description (OSD) was updated as part of the final correlation of the Spokane County, Washington, soil survey
  • Comparison of soil properties as influenced by organic and conventional . . .
    These studies indicate that, in the long-term, the organic farming system was more effective than the conventional farming system in maintaining the tilth and productivity of the Naff soil and in reducing its loss to erosion
  • Comparing landscape-scale estimation of soil erosion in the Palouse . . .
    The native soils in these landscape positions generally were shallow to silty clay loam or silty clay argillic horizons (Naff series and related soils) and erosion now has brought argillic materials into the tillage zone across the Palouse (7)

    For decades, erosion and degradation have dewatered the wetland By installing structures to help spread out water and replanting native vegetation, restoring this green gem will provide more than 16 million gallons of enhanced water storage annually
  • Erosion Impacts on the Palouse Misunderstood
    Soil series such as the Risbeck, Endicott, Naff, Garfield and Thatuna have paleosol horizons in the rooting zone In Risbeck soils, erosion increases the percentage of cemented hardpan fragments in the rooting zone, effectively reducing the rooting volume
  • Comparison of soil properties as influenced by organic and . . . - JSTOR
