Tag: soil samples

In agriculture, a soil test is the analysis of a soil sample to determine nutrient and contaminated content, composition, and other characteristics such as the acidity or pH level. A soil test can determine fertility, or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility and inhibitions from the presence of non-essential trace minerals. The test is used to mimic the function of roots to assimilate minerals. The expected rate of growth is modeled by the Law of the Maximum.

Advantages of Incremental Sampling Methodology for Landfill Sites

Advantages of Incremental Sampling Methodology for Landfill Sites

Conventional soil sampling and sample preparation methodologies can be inadequate in addressing the level of contaminant heterogeneity in both residential and industrial sites. The Escambia County (Florida) Waste Services Department (ECWSD) assessed the utility of multi-increment sampling versus traditional grab/discrete sampling and found that it yielded reproducible and more representative

Insights From the Journey

One of the great gifts of writing is the knowledge that one gains from the research necessary to create intelligent composition. My high school English teacher—who also taught Kurt Vonnegut—once told me that there were seven basic plots in literature and not to worry about outlining a wholly original narrative,

Compaction Techniques
There are basically two ways to compact soil: the static application of heavy loads or the repeated dynamic application of smaller loads at high frequencies. Most compaction equipment utilizes both types of forces. These forces are in turn each divided into two separate techniques for applying these forces:

Study Finds Soils Retain Fukushima Radiation

March 24, 2015 – Radiation suddenly contaminates the land your family has farmed and lived on for generations. Can soil play a role in protecting crops and human health? Research in Fukushima, Japan may lend an answer. On March 11, 2011, a magnitude 9.0 earthquake and tsunami caused wide spread

Making Rain Gardens Work

Making Rain Gardens Work

By Margaret Buranen Time is the test that reveals how well a rain garden is working. Time tells whether the rain garden’s design and construction are as effective as they were projected to be. Portland, OR, has a number of rain gardens that meet the test of time, including the

USGS Releases National Maps of Elements and Minerals in Soil

May 21, 2014 – The U.S. Geological Survey has released a  set of maps  depicting the distribution of selected chemical elements and minerals in soils across the country. Understanding the composition of soil is important for a variety of reasons. Specialists in agriculture and food safety find soil data useful
