Request for Proposals: Laboratory Measurements of Soil Samples

Overview

The National Fish and Wildlife Foundation (NFWF) seeks a qualified contractor to perform laboratory analyses of soil samples pulled from fields that were enrolled and cover cropped as part the Farmers for Soil Health (FSH) program, a USDA Partnerships for Climate-Smart project (Award NR233A750004G003).


Background

Within its portfolio of agricultural programs, NFWF provides funding for projects that accelerate the adoption of conservation practices on private working lands. Funded projects provide technical and financial assistance that help farmers enhance wildlife habitat, soil health, water quality, and carbon sequestration while providing important social and economic benefits to agricultural producers. 

In 2023, NFWF received a $95 million award from USDA under the Partnerships for Climate Smart Commodities program. Administered by NFWF, Farmers for Soil Health is a farmer-led partnership of the Soy Checkoff, Pork Checkoff, and National Corn Growers Association. Farmers for Soil Health aims to accelerate long-term cover crop adoption by providing financial incentives and developing a marketplace platform that quantifies, verifies, and facilitates the sale of ecosystem benefits. In its targeted 20-state geography1, FSH supports and expands technical assistance, enrollment, and education programs.

In addition to driving cover crop implementation, FSH is committed to analyzing the associated environmental benefits. NFWF is simultaneously seeking a soil sampling contractor to sample cropland soils in enrolled fields across the 20-state Farmers for Soil Health project geography. The selected contractor will collect samples from 600-800 sampling locations2 in Spring 2025 after enrollees’ first year of cover cropping. The selected contractor will resample these same 600-800 locations using GPS coordinates in Spring 2027, after three consecutive years of cover cropping. At each sampling location, five individual samples will be collected: 

  • Two bulk density samples collected using a 7.5 cm-diameter core (0-15 cm and 15-30 cm depths)
  • Two soil health and carbon samples collected as composites using a push probe (0-15 cm and 15-30 cm depths), following Soil Health Institute’s Sampling SOP
  • One composite sample of intact aggregates collected via shovel slices (1 sample at 0-7.5 cm depth)

The soil sampling contractor will ship samples to the laboratory analysis contractor in batches, ensuring the integrity of the samples prior to and during shipping. Delivery of laboratory analysis results for each batch would be expected within one month of receipt of samples.

1The following 20 states are eligible to participate in the Farmers for Soil Health Climate Smart Commodities Partnership: Delaware, Illinois, Indiana, Iowa, Kansas, Kentucky, Maryland, Michigan, Minnesota, Missouri, Nebraska, New York, North Carolina, North Dakota, Ohio, Pennsylvania, South Dakota, Tennessee, Virginia, and Wisconsin.

2We anticipate that there will be 600-800 sampling locations distributed across 300-400 fields.

Request

The National Fish and Wildlife Foundation requests proposals to perform laboratory analyses on soil samples, providing reports on the following metrics3:

  1. Total carbon and nitrogen via dry combustion;
  2. Inorganic carbon on select samples via modified pressure calcimeter;
  3. Aggregate stability via slaking image analysis;
  4. 24-hour carbon mineralization potential via alkaline trap or gas analysis;
  5. Oven-dry weight of samples for calculation of bulk density (680 cm3 core volume);
  6. Particle size analysis via hydrometer with wet sieved sands; and
  7. Soil pH via 1:1 soil-water slurry. 

Samples will be shipped in batches as collected, and data delivery for each batch would be expected within one month of receipt of samples.
