Amendments and seeding did not augment erosion control structure effectiveness in dry rangelands, 2021-2023

This study investigates the effectiveness of combining rock structures with organic amendments (wood mulch or compost) and native perennial grass seed addition to address erosion on rangelands. The study was conducted across five cattle ranches in New Mexico with 9-18 active head cuts studied at each ranch. Rock rundown structures were built at each headcut and a plot above each structure received an organic amendment treatment (compost, mulch, or control) and seed addition treatment (seeded or control).
