Soil Survey Investigations Report No. 52,
“Application of Soil Survey To Assess the
Effects of Land Management Practices on Soil and
Water Quality,” is now available online. This
report describes a study using an exploratory
technique developed by NRCS
to estimate the loss of nitrogen and phosphorus
caused by runoff and leaching in agricultural
watersheds. The study included watersheds in
Nebraska and West Virginia. The NRCS
technique is quick and cost effective because it
utilizes existing climatic, hydrologic, and soil
survey information. |

There are seven long-term soil-climate stations
in Antarctica that were set up to study the
effects of latitude, elevation, and soil age.
Each station monitors soil temperature, soil
water content, air temperature, relative
humidity, solar radiation, and wind (speed and
direction). Measurements are made at 20-minute
intervals and averaged and recorded every hour.
Antarctica data for 2009 is now available. |
