# Tag: types of soil

In terms of soil texture, soil type usually refers to the different sizes of mineral particles in a particular sample. Soil is made up in part of finely ground rock particles, grouped according to size as sand and silt in addition to clay, organic material such as decomposed plant matter.

# Estimating Earthwork Volumes

Formulas and methods for determining the volumes and areas of regular shapes and surfaces go back at least as far as ancient Greece. Pythagoras and other mathematicians determined those formulas that are still used to calculate the volumes of spheres and pyramids, as well as the areas of curve conic

# Soil Water Sensors

SOIL MOISTURE MONITORING CAN be useful as an irrigation management tool for both landscapes and agriculture, sometimes replacing an evapotranspiration-based (ET) approach or as a useful check on ET-based approaches since the latter tend to drift off target over time. All moisture sensors, also known as soil water sensors, measure

# Slide Rail Rules!

Often touted as the most flexible shoring system available, the slide-rail system is a vertical sheeting and trench support system that allows an excavation to be safely and economically shored from ground level to subgrade without any soil movement. Arguably, the slide-rail system has become the preferred shoring method for

# How the Savvy Contractors Roll

You don’t have to sell the Oregon Department of Transportation on the benefits of intelligent compaction. The department has already made a forceful argument that technology-guided roadway compaction can save money, allow construction crews to finish roadway projects in less time, and result in highways that last longer before they

# Two Ways to Install Silt Fences

The right way, it turns out, has a lot of variables, as any contractor knows. The choices are dictated by the type of soil, the slope gradient, and the length of time a job may take, as well as other influences. The wrong way often has…

# Innovation Ups Irrigation IQ

All growers want to see their crops, gardens, and landscapes flourish. Competition among manufacturers of irrigation controllers, sensors, and flow meters is driving innovation at high speed in this digital age, to satisfy the market.

# Landfill Mining: Current Trends

The beneficial purposes can include recovery of recyclable materials, recovery of soils for use as daily or intermediate cover in active landfills, or recovery of land area for redevelopment. As urban sprawl has continued in many metropolitan areas, landfillsâ€”which previously were located in areas relatively distant from the population centersâ€”are
