Cells with red arrows in them have helpful hints and instructions
The Blank data worksheet is for making hardcopies.
To successfully use this worksheet enter the hydrometer readings, temperature, sample size, blank readings, HMP solution concentration, and if needed sieved sand size weights in the appropriate blue boxes in the LAB Template worksheet.
Once these values have been entered the USDA texture will automatically be calculated and plotted in the corresponding Sample worksheet.
The worksheets have been protected using the password "soilsurvey". This is for your benefit to reduce the potential for worksheet corruption.This Spread sheet was developed using the Particle size analysis by Hydrometer method outlined in SSIR 51 - SOIL SURVEY FIELD AND LABORATORY METHODS MANUAL 3.2.1.2.1

Sieved sand percentage varies from hydrometer sand percentage. Texture Name Calculator in the Sample worksheets uses a combination of the sieved sand percentages and the clay from the hydrometer method. However, if the sand percentages were not sieved then the texture calculator is not able to properly differentiate some of the sand, loamy sand and sandy loam textures. Estimates from the nomograph for the hydrometer are provided corresponding to the 270 mesh sieve = .053µ and the 300 mesh sieve = .047. These estimates can be used as a second check against the .05u very fine sand vs. silt break. (The NSSL uses a no. 300 sieve)

Sieved sand percentage varies from hydrometer sand percentage. Texture Name Calculator in the Sample worksheets uses a combination of the sieved sand percentages and the clay from the hydrometer method. However, if the sand percentages were not sieved then the texture calculator is not able to properly differentiate some of the sand, loamy sand and sandy loam textures. Estimates from the nomograph for the hydrometer are provided corresponding to the 270 mesh sieve = .053µ and the 300 mesh sieve = .047. These estimates can be used as a second check against the .05u very fine sand vs. silt break. (The NSSL uses a no. 300 sieve)

The Total Percent Sand in the Sieved Sand Sizes Table is used here. If it is zero then the percent sand by hydrometer method is used.
G5
This cell is automatically calculated when you enter the hydrometer readings in Cells D15 and D16 of the LAB Template Worksheet.
A6
If sands are sieved enter the data in the chart in the LAB Template Worksheet. The percent sand estimated by sieving often varies from the percent sand estimated by hydrometer method. The Texture Name Calculator in the Sample worksheets uses the adjusted percent sand, silt and clay. You can review the 30 and 60 second R readings. If you have a lot of very fine sand, you may assume that you lost some from the 270 sieve = .053mm versus .05mm, or if you use a 300 sieve = .047mm you may assume that some coarse silt is included in the very fine sand fraction. (The NSSL uses a no. 300)
G7
Sieved sand percentage varies from hydrometer sand percentage. To make the Texture Name Calculator in the Sample worksheets work the hydrometer sand percentage must equal the total (rounded) sieved sand percentage if the sample was sieved. The 30 and 60 second R readings are provided for you to evaluate the very fine sand. The field labs are provided with the number 270 sieve = .053 mm. The National Soil Survey Laboratory uses the No 300 sieve = .047 mm. (The NSSL uses a no. 300)

This is the log slope between the 2nd and 1st points on the graph. It is expressed by ((Log(y2)-log(y1)) / (x2-x1).

This is the Log(y) INTERCEPT of x by y, expressed as B = Log(y2) - (log slope * x2)
M8
Where x = 50 is the break between Sand, and Silt. This is calculated using Y=10^log(y) where log(y) = log(slope)*x)+log(y) intercept

If sands are sieved enter the data in the chart in the LAB Template Worksheet. Sieved sand percentage varies from hydrometer sand percentage. To make the Texture Name Calculator in the Sample worksheets work the hydrometer sand percentage must equal the total (rounded) sieved sand percentage. i.e. you will have to tinker with the 30 and 60 second R reading or if you have a lot of very fine sand assume you lost some from the 270 sieve = .053mm versus .05mm, or if you use a 300 sieve = .047mm assume you caught some coarse silt. (The NSSL uses a no. 300)

K8
This is the log slope between the 2nd and 1st points on the graph. It is expressed by ((Log(y2)-log(y1)) / (x2-x1).
L8
This is the Log(y) INTERCEPT of x by y, expressed as B = Log(y2) - (log slope * x2)
M8
Where x = 50 is the break between Sand, and Silt. This is calculated using Y=10^log(y) where log(y) = log(slope)*x)+log(y) intercept
K11
This is the log slope between the 4th and 5th points on the graph. It is expressed by ((Log(y2)-log(y1)) / (x2-x1).
L11
This is the Log(y) INTERCEPT of x by y, expressed as B = Log(y2) - (log slope * x2)
M11
Where x = 2 is the break between Sand, and Silt. This is calculated using Y=10^log(y) where log(y) = log(slope)*x)+log(y) intercept
