Here's a legume that has the N nodules on the roots. It's Hariy Vetch. Nice climbing biennial vine, self seeding, can be noxious up in the northern climes. It's the viny plant with purple flowers.
I just listened to this part of the book today.View attachment 17892015 View attachment 17892014 Here’s a bit of information from Steve Soloman.

The more I look for relevant information to claims I think I’ve found so I find frank blasting out what I expected@Dr.RedWhite
I absolutely LOVE how no one has the right answer nor does anyone seem to know how to actually figure this out. (because it gives me an opportunity to share and educate others)
Only thing missing from this thread is Gascan telling everyone how stupid they are and why they should be using neem meal instead!!!! It ALMOST feels like the old organic soil forum days!!!
ROFLMAO.
There's no need to fear, dank.Frank is here!!!!
WATCH AND LEARN, everyone...I have made posts about this exact topic - pertaining to the substitution of ANY amendment for NPK profiles. It doesn't take a bunch of conjecture and it doesn't take a bunch of round about explanations of the nitrogen cycle to guess what might happen. I'm willing to make these types of posts so ass hole crooks like those who stole our soil recipes at Build a Soil could be shown for the poser con artists they really are. They have no clue what they are doing - they are just preying on people's desire to grow in an organic or natural format. They are clowns who would not exist if not for the information that was shared and exchanged in the Organic Fanatic Collective social group back over a decade ago. Culture vulture capitalist FRAUDS. My signature, applies to people like the owner of that business. (Jeremy)
Now that I have gotten that out of the way...
It takes a scientific formula and an understanding of how to use amendments efficiently. (I'm actually responsible for developing the 2nd formula listed in this sticky. (the directions in bold typeset) It's my own equation; my own creation. Part A was commonly used in conventional agriculture and provided by university extensions but it was designed for single element ionic salts, ie 50-0-0. If using an organic amendment that had a diversified NPK ratio, there was no formula to give credence to how much of the other elements were being added. I fixed that problem and verified it's correctness and accuracy via multiple weeks of discussions with soil scientists at Cornell.)
Measuring Amendments
I've gotten asked countless times over the years for the weight of various amendments. It would have come in handy for myself years ago if this type of information had been made available. With that in mind, this chart, expresses the weight (in grams) of various amendments in different...www.icmag.com
Volume is 3 dimensional. 1 cu ft is 6.47 gallons of media. You can insert a standard tillage depth of 7.6" to give a volume metric to determine how many sq ft is in 6.47 gallons of media. IT'S NOT MUCH.
0.925' x 0.925' x 7.6" = 6.5 - so let's say you are working with 0.925 sq ft. THAT is the area you are trying to amend.
1/2c of blood meal weighs roughly 156g and generally has an NPK of 12-0-0.
Fertilizer is measured in lbs per acre so you have to convert.
To that area, you have traditionally applied, 156g of 12-0-0.
156g = 0.344 lbs
1. 0.344 lbs of blood meal x 0.12 (% of nitrogen) = 0.04128
2. 43,560 sq ft per acre / 0.925 sq ft = 47,091.892
3. 0.04128 x 47,091.892 = 1,943.95 lbs of N applied
So you want to attempt to provide that same level of Nitrogen, using a different amendment.
Alfalfa meal, traditionally runs about 3-2-2, but we are just focusing on the nitrogen replacement.
1. 1,944 lbs/acre / 43,560 sq ft/acre = 0.04463
2. 0.04463 x 0.925 sq ft = 0.04128
3. 0.04128 / 0.03 = 1.376 lbs of Alfalfa meal needed.
Alfalfa meal weighs about 246g per cup.
1.376 lbs = 624.1431 grams
624.1431 / 246 = 2.537
So you need about 2.5 cups of alfalfa meal.
You're welcome. This is why ICmag will ALWAYS be the best resource for growers. We will ALWAYS help educate people who want to learn to do it the right way. Good luck with your grow!
PS - F.U.C.K. Build-a-Soil - in case you missed that.
This is why my water only soil mixes and recipes ACTUALLY WORK and you don't see me telling anyone to buy all these additional aloes or coconut water or ferments or or or or or or. They HAVE to sell you those things to cover their asses for having inadequate soil recipes to begin with!!!
I believe in TRUE OPEN SOURCE KNOWLEDGE - and overgrowing prohibition by enabling people to succeed. They believe in getting more of your money.
