I have a conundrum. I'm not sure if my young pumpkin has yellow vine disease or an excess of nitrogen. The leaves are wrinkley and the edges are browning. Thee is some browning in the middle of the leaves too. They wilt a bit in the sun. I usually have problems with squash vine borers, but this seems different. I took pictures, but don't see how to upload them. Thanks for your help!

Start a grower diary and upload the photos there.

Thanks! I made one this am. I'm just waiting for the site to approve it.

you must have seen something like this
1 cubic ft = 0.0283168 cubic meter

Volumn = 1,000 cubic ft x 0.0283 cubic meter/1 cubic ft
Volumn = 28.3 cubic meters

multiply by the density to get weigh
convert soil density to kg/cubic m
Soil density = 1,100 kg/ cubic meters

Weight = 28.3 cubic meters x 1,100 kg/cubic meters
Weigh = 28,200 kg (this is how much the soil in our 1,000 sq ft patch weights [which is 62,390 lbs])

one part per million is 1 millionth of that weigh
1 ppm = 28,200 /1,000,000 = 0.0282 kg
df0.0282 kg = 28.2 g

So for Manganese Sulfate (32%)
yes divide 28.2 g / 0.32 = 88.2 grams

So you would add 88.2 grams of Manganese Sulfate to your 1,000 sq ft patch to increase 1 ppm.
