Tag: soil test

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.

Project Profile – Barren Arkansas Roadside Springs to Life

AFTER COMPLETING AN OPEN-CUT slope for a recent highway project, the Arkansas State Highway and Transportation Department (AHTD) encountered a difficult mitigation challenge: a soil bed totally unsuitable for organic growth. The highly acidic soil, composed primarily of clay, rejected initial attempts at sustainable vegetation and threatened to create a

Managing for Drought

Managing for Drought

The mania for a green lawn, or in some cases green anything, across many regions of the US has been quelled by recent droughts (thankfully now abating). Even long before water meters were spinning at record rates for golf resorts, private homes, and corporate campuses, scientists have been devising technologies

From Titusville to Tycoons

From Titusville to Tycoons

The evolution of the oil and gas drilling industry in the US has all the essential components of a blockbuster adventure novel—colorful characters, challenging landscapes, spectacular discoveries, deals and dollars, and a lot of each of them.

FREE! Using Software for Successful Project Design

From drones to project software, technology has infiltrated construction and erosion/sediment control, maximizing our efficiency, and improving project success. The greatest impact? Coupling this new technology with field-tested fundamentals of revegetation and erosion control.

Join Matthew Welch, CESSWI to explore the latest in project design software; its parameters, calculations, and applications;

Sprouting BMPs

Sprouting BMPs

Vegetation is often the BMP best suited for curbing erosion; however, not every site contains the best soil, which is crucial for quick seed germination and plant growth. Choosing the right seed can often solve such problems. Plants that tolerate salt are perfect for marshes that take ocean backflows, and

From the Ground Up

From the Ground Up

Anyone who’s worked with a containerized plant has seen evidence of how strong plant roots can be. Adhering tightly to the soil, roots form a living net of fibers that often require a sharp knife, or ax, to rend. Of course, with any erosion control project, plant materials (especially those

Seeds of a Certain Sort

Seeds of a Certain Sort

More each day, plants that “could do the job” are not; a perennial grass that might stop a site’s erosion in one season won’t be used if it’s not native to the area. Increasing use of native plants-the definition narrowing down from “regional” to “sub-county”-offers challenges for those who sow

Revegetating With Native Plants

Revegetating With Native Plants

Field experience has made it clear that if one is to be successful growing native plant communities, a functional microbial community is imperative. Use of native seeds in revegetation follows the current societal focus on multiple use of lands, a policy toward enhancing ecosystem diversity and function, and conservation of
