There is a need for accurate, quantitative soil information for natural resource planning and management. This information shapes the way decisions are made as to how soil resources are assessed and managed. This paper proposes a novel method for whole-soil profile predictions (to 1m) across user-defined study areas where limited soil information exists. Using the Edgeroi district in north-western NSW as the test site, we combined equal-area spline depth functions with digital soil mapping techniques to predict the vertical and lateral variations of carbon storage and available water capacity (AWC) across the 1500km2 area. Neural network models were constructed for...

Hey so here's the deal. I ahve searched for hours looking for the solution to my problem but am not 100% I've found it yet. My situation is I have 2.

Hey guys, Can I start seedlings in rockwool and then put the whole cube into a soil mix once it starts to miture a littlebit???

Surfactants affect the water-related soil properties of water-repellent soils but may also affect those of wettable soils. The effect of five surfactants, belonging to three different types, at different concentrations on the hydrophobic behaviour of a nonrepellent agricultural calcareous soil is studied. Native soil was treated with anionic (Aerosol 22), cationic (TDTMA and HDTMA) and non-ionic surfactants (Triton X-100 and Tween 80) and vapour and liquid hydrophobic characteristics were evaluated. Anionic and non-ionic surfactants at any concentration increase water vapour adsorption but cationic ones reduce it when applied to soil above 50% soil cation exchange capacity. Absorption of liquid water...

Just completed my first test on the soil to guage where I'm at. I have a couple plants almost 2 feet tall and seedlings around 8" tall. Everything is in the soil, but the stems are turning purple.

Peat, formed over thousands of years from decomposed trees, grass and scrub, contains gigantic quantities of carbon dioxide, which used to stay locked in the ground. It is now drying and disintegrating, as once-soggy swamps are shorn of ...

Pollen-assemblage data from a sediment core from Hulun Lake in northeastern Inner Mongolia describe the changes in the vegetation and climate of the East Asian monsoon margin during the Holocene. Dry steppe dominated the lake basin from ca. 11,000 to 8000 cal yr BP, suggesting a warm and dry climate. Grasses and birch forests expanded 8000 to 6400 cal yr BP, implying a remarkable increase in the monsoon precipitation. From 6400 to 4400 cal yr BP, the climate became cooler and drier. Chenopodiaceae dominated the interval from 4400 to 3350 cal yr BP, marking extremely dry condition. Artemisia recovered 3350–2050 cal yr BP, denoting an...

The physical nature of sediment transport favors the movement of smaller and less dense materials, typically resulting in greater (enriched) sediment total phosphorus (TP) and organic matter (OM) concentrations than those of the parent soil. In rainfall–runoff, residue cover significantly influenced P enrichment, with the median TP enrichment ratio (TPER) for corn-grain (1.4) being significantly greater (p=0.007) than that for corn-silage (0.8) and manured corn-silage (1.0) fields, which were similar. While greater P enrichment was observed in snowmelt compared to rainfall–runoff, attributable to correspondingly high OMER values, TPER was unaffected by treatment differences (p=0.60). The OM enrichment was much higher...

We present a novel approach to multiscale fractal image analysis for monitoring the dynamics of the soil pore/solid network roughness due to moisture content changes. Roughness of the gray-level probability density function (PDF) of subsequent images of the drying soil was expressed in terms of its Hurst exponent (HPDF), which correlated significantly with the soil dielectric permittivity and gravimetric water content, as well as with micro-horizon depth and the temporal progress of drying. We documented an intermittent character of the water content dynamics, correlating with oscillations of the pore/solid interface roughness. Our technique of PDF roughness analysis of digital images,...

Nitrogen (N) from urine excreted by grazing animals can be transformed into N compounds that have detrimental effects on the environment. These include nitrate, which can cause eutrophication of waterways, and nitrous oxide, which is a greenhouse gas. Soil microbes mediate all of these N transformations, but the impact of urine on microbes and how initial soil conditions and urine chemical composition alter their responses to urine are not well understood. This study aimed to determine how soil inorganic N pools, nitrous oxide fluxes, soil microbial activity, biomass, and the community structure of bacteria containing amoA (nitrifiers), nirK, and nirS...

Despite advances in treatment regimens and the best efforts of nurses and doctors, about 70% of all people with severe burns die from related infections.

With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported.
