[@Carlo_B]

the only way to proceed with fertilization is to get a soil test. but if you have many different plants in the same area it is impossible to give the correct amount of fertilizer for each plant, even with the soil test. You'd better spread wood chips or compost, or both. Soil tests and specific fertilizations are useful for agricultural purposes only, when you have the same type of plants in one big area, eg. a vineyard

Someone asked me the other day what I do to make my garden so nice and I took them out there and scooped a shovel full of dirt out spread on the ground and there was about thirty red wiggle worms in the one shovel full. I said to the person look at the life and consistency of the soil that's what makes it good. I very rarely use fertilizer at all. Just good compost and manure with a few other organic amendments. My secret is I have access to a compost pile that is absolutely amazing. It has been added to from a camp that has horses and a commercial kitchen that has been adding to it since 1950. It is some of the richest best soil I have ever seen and I'm so blessed to be able to use it.

[@williamwaters4506]

Great video, your final comment sums it up - before you pour/spread fertilizer on your soil, have it tested. You might not need any NPK, you might need (for example) calcium or your pH might be out of balance.

It reminds me of the greenest lawns my Polish grandma had using Schlitz beer in an old sprayer. Think she used to get a case of it for like $4.99. Could drink a 6 pack and water the whole lawn.

i have 12-10-18 and for a 3-1-2 ratio i might add fish mix and wormcastings for my potting soil, thanks!

[@Chris-op7yt]

i mostly use 20:20:20 +TE. people have been fooled by organic movement and domestic fertilizer companies, to buy mostly water/filler, as long as it smells like it does magic. you can water down the 20:20:20 to whatever strength you want. on the other hand, weak domestic grade fertilizer typically does not much at all, at the recommended dilution, so there's no danger of ever burning the plant or actually fertilizing it for growth.

[@ellellbee]

[@blowitoutyourcunt7675]

Horse compost is better from what I've heard from my mate who uses it to "innoculate" her compost pile.

Organic poo only, dewormers that are given to horses could have a very negative impact on your compost pile for example.

Your awesome dude. Lol. 6.2 is fine with me on my beer. Not big on that high gravity. If I want gravity I will gravitate towards an 80 to 90. But that's usually when I'm deficient.

Question - Beyond the ratios...I have a bunch of older (several year old) synthetic liquid Ferts still in the bottle..how long do the molecules stay plant viable? I'm guessing there is no expiry date...but that's a guess, and not very sciency.

[@Gardenfundamentals1]

sort of. Plant nutrient molecules will not decompose and they stay viable. What can happen over time is that some precipitate out and form a solid. But they can still be used.

Which ratio of NPK can i use on my cocoa farm?

[@hugolozada9192]

Hi can l mix the garden soap with oil thank you

[@jeil5676]

OK. From what I've been told, N:P:K ratios on a container, explain the percentage of immediately available nitro, phos, potas. by dry weight....so how does that factor into a bottle of fish emulsion? Its not dry and I have no way of knowing how much water is in it. There may be nitrogen thats not immediately available but microbes will eventually do so. And, this is all dependent on how much water i dilute into and, how much soil I spread it over....This is just too much for me to handle lol.

[@srantoniomatos]

Its much simpler: if you clearly see that your soil is not fertil (plants dont volunteer to grow, andmost things dont grow, or grow small and slow), which is not common at all: 1- aplly as much of organic manure and compost and /or mulch as like. Usual a bit every year is good and enough. 2 - if you go sintetic just spread a bit by hand, a slow realease its enough for at least a year or 2. 3 in doubt dont aply or aply very litle amount.

[@Gardenfundamentals1]

" N:P:K ratios on a container, explain the percentage of immediately available nitro, phos, potas. by dry weigh" - that is not true. It is mostly true for synthetic fertilizer, but take urea for example. It is a 45-0-0, but most plants can't use urea, at least not in large amounts. Urea does turn into nitrate fairly quickly which plants can use. NPK on organic fertilizer, like fish emulsion, is usually the total amount of nutrients and they might not be available for months or even years. Liquids are mostly water, so as a rough guide you can assume 1 gram per ml of liquid - which is the density of water. If the N is 10%, then there is 0.1 gram in 1 ml.

[@jeil5676]

[@ASpinnerASpinner]

I have never seen a recommendation to use X quantity of fertilizer to "your garden".

if 3-1-2 is a good ratio and N is 3 then do we want to actually end up with 3-0.4-0.8? P being phosphate not pure phosphorus and K being potash not pure potassium. Thank you for explaining this “math” problem. Traditional measures can screw things up to the layman. A two x four” piece of lumber is another example.

I bought your books #1and#2 I have a question, for pot tomatoes and peppers the ratio 3-2-1 is good for all growing stages? Tanks

Yes. Unless you are doing hydroponics and have a lot of testing equipment you can't fine tune the ratios any better.

[@josethunder6016]

Hi and thanks for that helpful video about NPK . I am beginning in hydroponic and want to know more about a good formula . So question I want to ask may be not in the field of that video , but I am sure that you do have the knowledge about how to feed plants without soil . So my first question is " if I have nutrient bag with 9-9-39 and by adding mono ammonium phosphate ( MAP) with 12-61-0 , will I get an NPK 21-70-39 ? and if I divide the ratio of the MAP by 2 , will I get a 15-39.5-39? And what's about the Epsom salt that has 0 NPK and the Calcium Nitrate that has NPK of 15.5-0-0 which boost more the Nitrogen to finally give me a solution of NPK 30.5-39.5-39 . Will this be a good mixture? Thanks in advance for a reply 😊

[@Gardenfundamentals1]

"if I have nutrient bag with 9-9-39 and by adding mono ammonium phosphate ( MAP) with 12-61-0 , will I get an NPK 21-70-39 ?" - NO. Assuming you mix 50/50, you would get a 10.5-35-19.5. If you then mix this with a 0-0-0, in a 50/50 ratio, you get 5-17.5-10. The NPK numbers are % numbers - need to do the math using percents.

[@josethunder6016]

@@Gardenfundamentals1 Thanks for the reply , I was assuming about a 100% , but your answer is about 50/50 then it's normal that 100/100 will give then 2170/39 . By the time ( one month ) I have been making plenty of experience using EC and PH meter for some calculations based on the mixture I stated above , then using more or less some different mixtures to get a good balance for beginning with lettuce and it works pretty fine. Thanks again for your reply , have a nice day 😃

[@ausfoodgarden]

Can someone explain why the Nitrogen is still 10% when I'm assuming most fertilizers would be Ammonia-based, such as Ammonium Nitrate, Urea etc. Wouldn't the actual N be a lower percentage same as the others?

Succulents and most conifers need much less nitrates. In fact, they can get sick and die from the imbalance.

Is how often required fertilization a fourth factor ?

[@Gardenfundamentals1]

how often you fertilize is important.

[@geraldblount4159]

Well it depends on the size of the person just like it depends on how many particles are in the water

[@Carlo_B]

So if for example I buy a bag of 20 kg of NPK 10 - 5 - 8 fertilizer, I have 2 kg of nitrogen, 2 Kg of phosphorum and 6,4 kg of potassium, is it right? But 2kg +2kg + 6,4kg is a total of 10,4 kg, but the other 9,6 kg inside the bag what are they made of?

[@Gardenfundamentals1]

No. The fertilizer is 23% of the bag (10+5+8), which is 4.6 kg. The rest is filler - it used to be sand. 20 kg of NPK 10 - 5 - 8 fertilizer is 2 kg nitrogen, 0.8 Kg P and 1.5Kg K www.gardenmyths.com/fertilizer-npk-ratios-what-do-they-really-mean/

[@Carlo_B]

@@Gardenfundamentals1 I'm sorry, but I still don't understand. 2kg + 0.8Kg + 1.5kg = 4,3Kg and not 4,6kg And, how did you get the P value and the K value? In your article you wrote: "Let’s say have a 25Kg bag of rock phosphate with an NPK value of 0-32-0. To figure out how much phosphorus you have in the bag, multiply 32 x 0.436, to get the % P = 14%. Since you have a 25 Kg bag it contains 3.5 Kg P (25 x 14%)." It seems to me that you get the P value calculating it on the whole bag, and not on the 32% of the 25kg bag, that it would mean 8kg of fertilizer. Isn't it?

Imagine you drink 33 bud beer, you literally drink 99% alcohol, very true

[@bryanswanson5007]

No, thats not true at all, you are thinking about it all wrong. The percents are not added. If a beer is 3% that just means that 3% of the liquid contains alcohol. If you drink 100 beers its still 3% alcohol by volume. It doesnt change.

[@johnr990]

Some of the fertilizers you only need around half or more of the recommendation. They are selling a product and want you to use the hell out of it and buy more. The University of Florida IFAS has a study that was aimed at lowering nitrates in the ground water because everybody seems to over fertilizer and also nutrient lock the medium. I worked on that project with them.
