Sugar can be used as a weed killer, particularly broad leaf weeds, rather than grasses or perennials. It is a carbon nutrient that contains no nitrogen. Sugar can limit the growth of plant that do not tolerate low nitrogen environments. This is because microorganisms in soil are forced to source their necessary nitrogen from soil. This leaves little for ...

After Saint Helens, forest managers thought to harvest timber in the area and replant it because they assumed nothing would ever grow again. Instead they left it alone and the eruption epicenter is now the largest outdoor ecological restoration experiment. Scientists monitor it's rate and aspects of it's regeneration. Contrary to being a dead sterile ...

Falling ash is usually not a concern for agriculture. But the particulate matter (smoke) can harm agricultural products. Not through the soil, but by exposing the plants to smoke over long periods. In particular, many vineyard owners are very unhappy with the recent increase in wildfire smoke in the west. It taints their grapes and makes the wine less ...

If there are any beehives in the area, it's likely the bees will discover this and go to it preferentially over other sources of sugars. That will reduce their utility to the beekeeper by removing their pollinating effects and by filling the combs with artificial honey that is likely an unappetizing color to boot. Finally, it's possible that the ingredients ...

"Soil" is a loose amalgam of various earthen materials and organic detritus, thus conditions that create soil in various regions; soil "Thickness" depends on where soil ends and regolith (solid rock) begin

Downwash can be part of some erosion environments where minerals are moved down from their host rock environment to another location. Black Snake Range - Granite Slopes, Victoria, Australia The crest of the divide rises to almost 400 metres and at this site there are numerous exposed granite slopes and large boulders near the ridge crest. The lower slopes ...

From the readme.doc file, it looks that 1, 2 and 3 following AF and the other soil symbols in the excel files you mention are about this: Texture classes reflect the relative proportions of clay (fraction less than 0.002mm), silt (0.002 - 0.05mm) and sand (0.05 - 2mm) in the soil. Three textural classes are recognized: coarse (1): sands, loamy sands and ...

If you are not in the position of following the steps suggested in Ash's answer, I'd suggest you to rely on existing data, as the ISRIC dataset "WISE derived soil properties on a 30 by 30 arc-seconds global grid", developed at Wageningen university and available here. This dataset is originally based on the FAO-Unesco Soil Map of the World (DSMW). ...

All weight percentages are calculated using the same formula: Mass Fraction/Total Sample Mass There are two different values for organic material in a soil and they're derived by different techniques: If you want to know how much bioavailable organic material is in the soil I was taught to use a chemical reagent to oxidise and strip organic carbon from the ...
