Help with figuring soil sample please

zeroma · March 25, 2016

I do get the gist of the soil sample test but my question is:

where the test says how much N to apply for example: 2.8# per 1000 square feet - our raised bed this applies to is 281 square feet. So do I divide that out and get an answer of .75# for our number of sq ft? and of course, do the same math with the other nutrients needed.

Second question, where the tests says to apply in multi applications blah blah blah, I don't just sprinkle some prior to planting? rather use it at different stages of the tomato growth?

sorry I had to copy and paste, I don't know how to put the picture of the report in here.

Turf and Ornamental Soil Analysis Results
Analysis Result Unit Optimal
Soil pH 7.7 5.8-6.6 Very High
Buffer pH
Organic Matter 10.9 %
Phosphorus 222 m3-ppm 41-68 Very High
Potassium 135 m3-ppm 195-302 Medium
Magnesium 427 m3-ppm 260-433 Good
Calcium 4391 m3-ppm 2457-3439 Very High
CEC 18.4
K Saturation 1.6 % 2.0-4.0
Mg Saturation 17 % 10-20
Ca Saturation 81.4 % 50-70
Crop Settings - CROP LIST
Year Prev Crop Next Crop Yield Goal

Fertilizer Recommendations for #23 Tomatoes, 30 ton
Nutrient Amount Unit
Lime [CaCO3] 0.0 lbs/1000 sqft
Nitrogen 2.8 lbs/1000 sqft
Phosphorus [P2O5] 0.0 lbs/1000 sqft
Potassium [K2O] 7.7 lbs/1000 sqft
Magnesium 0.0 lbs/1000 sqft
Calcium 0.0 lbs/1000 sqft
Sulfur 15.8 lbs/1000 sqft
Comments:
Apply most of N as multiple sidedressings, beginning at appearance of first cluster and based on soil N test (PSNT) 7-10 days prior. Fall or split apply K2O If rate exceeds 300 lb. or soil K exceeds Mg . Monitor and adjust nutrients with plant analysis.[/COLOR]

and yes, our soil is alkalin
