This software has been developed to help understand how the movement of moisture within the soil (Hydraulic Conductivity) is radically affected by the mix of Sand, Silt and Clay within that soil, and how the rate of water application will affect depth of moisture. When the soil is saturated, this movement rate is then known as "Ksat". Also, once saturated, water begins ponding, spreading and/or running off. Distribution is negatively affected and waste increases.

The SPREADSHEET at the bottom of the Soil Explorer affords the user to gain a better picture of how water and moisture levels vary over the first 24 hours following an irrigation. Example; you will be able to see where the amount of water applied exceeds the amount of water that will cause ponding and run-off waste.

If you wish to determine the composition mix of a soil sample, a Jar Test will do the job. This simple process requires only a few common items and can be completed in 5 minutes. To learn about performing the Jar Test click here:

Looking at the "Soil Composition Triangle" below; Select a spot or section within the the Triangle that represents a particular "Soil Type". Now, read the Sand coordinate (along the bottom - running up and left) for that spot and note the percent indicated. Next, read the Clay coordinate (horizontal line beginning at the left side) that runs to that spot and note the percentage list for that line.
You now have the Sand and Clay % data needed.

NEXT: Simply "plug the %" of sand and clay into the yellow data boxes.

NEXT; Using the drop-down box; select the number of emitters (emitter count) you intend to experiment with. This count determines application flow rate, and is listed in the results section. If you're not sure how many emitters you want to start with - the drop-down box offers a "Tell Me" option. Just hit calculate to see the recommendation - make the change & hit calculate again.

The Soil Explorer is a tool for experimenting with various soil types and application flow rates. This will enable you to see how, when these factors vary; the depth of moisture is affected. This in turn will help produce more efficient irrigation designs. Becuase the application rate is an input that you can adjust, this will allow you to see how applying water too fast will affect the ultimate depth of moisture in the soil.

The EXAMPLE button, located immediately below the drop-down box will provide for more information on selecting emitter count if needed.

The Explorer will caculate the % of Silt as a result of the Sand and Clay inputs. This assures the percentages all add up to 100%.
