Soil Health

Researchers have developed a new, easier way to find the answer to the question, "How much carbon is stored in soil?"

ARS researchers have developed a unique mobile system that assesses and maps out soil carbon to a depth of 30 centimeters (the plow layer) – all in real time.

Researchers worked with the Quapaw tribe to create high-resolution digital maps of soil properties for their tribal lands.

A new protocol addresses sources of variability and uncertainty in measuring microbial community composition and its connection with agricultural management and changing climate.

Researchers determined that winter camelina and pennycress are effective in reducing excess nitrogen and preventing its escape from farmland.

A team of ARS and Boyce Thompson Institute researchers in Ithaca, NY, may have found a weak link in the citrus-greening disease cycle.

Farmers can better determine how much or how little nitrogen to apply for optimal crop yields by using "Soil-Test Biological Activity" approach.

Researchers developed state-of-the-art sensors that estimate soil water levels using readings from electromagnetic pulses.

ARS scientists have shown that anaerobic soil disinfestation is a promising alternative to methyl bromide fumigation.

ARS has developed the LandPKS app to help farmers better monitor their soil and crop conditions to make better decisions about irrigating, weeding, and fertilizing crops.

A new garbage-processing technology reduces the municipal solid waste disposal in landfills and generates a co-product that can be used to reclaim damaged soils.
