Latest Soil physics Stories
Researchers trace a problem with a key climate model to its hyrdrology scheme and find a simpler scheme keeps simulations in line with real-world observations.
Researchers report in the Soil Science Society of America Journal that 3-D laser scanning can provide a more thorough analysis of a soil's quality, helping to further understand how healthy crops are produced. Soil researchers pay close attention to bulk density, as it is one of the most common soil measurements and it is often used as a measure of soil quality. A soil's bulk density can be indicative of the ease of root penetration, water movement, and soil strength. Measuring this...
By Keener, H M Wicks, M H; Skora, J A VOLUMETRIC IMPORTANCE Study develops consistent methodology for accurately measuring volumes of unprocessed and processed materials at yard trimmings composting facilities.
By Munch, E Franco, J; Deville, S; Hunger, P; Saiz, E; Tomsia, A P This work compares Two novel techniques for the fabrication of ceramic scaffolds for bone tissue engineering with complex porosity: robocasting and freeze casting.
Europeans want to peek into their soil and see how dry they are. And an Iowa State University professor is eager to help, and even check their results.
The first soil moisture maps with a spatial resolution of one km are available online for the entire southern African subcontinent. As soil moisture plays an important role in the global water cycle, these maps, based on data from ESAâ€™s Envisat satellite, will lead to better weather and extreme-event forecasting, such as floods and droughts.
By Jung, W K; Kitchen, N R; Anderson, S H; Sadler, E J ABSTRACT: Plant water and nutrient use for claypan soils are restricted by an argillic horizon (clay content > 500 g kg^sup -1^) that typically occurs 20 to 40 cm (8 to 16 in) below the soil surface.
U.S. scientists say they've determined rain evaporation and continental convection play an important part in the tropical water cycle.
By Pandey, C; Shukla, S A two-year study was conducted in 2002-2003 (season one) and 2003- 2004 (season two) at a seepage irrigated vegetable farm in south Florida to investigate the effects of soil organic amendment (composted yard waste) on movement of water in a sandy soil.
