Hello, Reddit! I recently bought fertilizer that is 15-0-0 +26.5 CaO and I am totally confused. It is agricultural grade calcium nitrate and it says that water soluble Calcium (as Ca) is 19.0% and water soluble Calcium (as CaO) is 26.5%. Does is mean that this fertilizer is roughly 38% calcium by mass, if percentage of calcium in calcium oxide is about 72%? Please help me to figure this out

The inclusion of probiotics in IQS organic fertilizer enhances soil health by promoting beneficial microbial activity. This can lead to improved nutrient availability for plants and enhanced soil structure. The combination of organic nutrients and probiotics can contribute to a healthier and more balanced ecosystem in your garden.

I was wondering if I could spray my orange peels with lab or a “compost starter” and put under a nitrogen loving plant as a fertilizer? Or maybe even just letting it sit in a little vinegar diluted with water to extract the properties before adding to my garden.

Tulsa, Oklahoma, free for pickup. I have 6-1 gallon containers of Emerald Harvest liquid fertilizer including supplements. Reason. I switched to organic. Harvest too large. Never thought I'd say that but, I'm pushing 80 .

Can I use expired fertilizer for plants? It's expired from a year or more. I don't remember whether it's organic or Its black in color and I can see some dry leaves powdered in it. Does it harm the plants?

first time posting on this subreddit and i have a bit of an issue lets say a crop needs 300:100:100 and since fertilizer prices are going up i wanted to cut on fertilizer usage , would it be wise to do something like 300: 50:50 or 150 :50:50
btw lets assume the soil has almost no nutrients i need a ratio that wouldnt stunt or kill the crop thank you all in advance

Please help me reddit. I need to make fish emulsion fertilizer from a fish (sucker fish) that contains heavy metals. Mostly cadmium, lead and Mercury. Can I remove this material once the whole fish decomposes after 8 to 10 months. Can I remove them and keep the organic solution suitable as a fertilizer? If someone can guide me I would really appreciate it. Thank you

I have a slow release fertilizer that i want to use so bad, but i like to add a very small amount of fertilizer to my water every time i water as its way easier for me to fertilize all the time compared to just once a month when barely any of my plants gets watered on the same day and i dont want to have to keep a fertilizer schedule.

Its the supertrive all purpose fertilizer with Mycorrhizae

It comes in a 1 kg / 2.2 lb bag with an NPK of 4-4-4

the instructions for use say to apply 1oz / 2tbs per sq. ft every 4-6 weeks

How would one go about making it into a powder or liquid to dilute every time i water? Has anyone had experience with this? I was thinking of just grinding it up and sprinkling a little bit into my watering can every time need to water. Any tips, ideas, and suggestions at all would be appreciated

Hi I put miracle gro individual packet into a watering can and then added water. It foamed up. Did my toddler put soap into watering can or is it normal for miracle gro to foam up?

I have unlimited supply of rabbit poop which is 2.4, 1.4, 0.6 NPK. Can I add phosphate rock and potash and make an 8-6-8 fertilizer for my garden? Are there any guides for how to go about calculating the amounts to make this ratio? Is the NPK value decided by weight?

I'm very knowledgeable when it comes to chemistry but not so much agriculture and plant growth. I'm trying to decide on how to handle this. I have about 8 pounds of eggshells that I've washed washed. Eggshells contain about 95% calcium carbonate. I figure I should turn it into a water soluble salt so it can be easily absorbed by my tomato plants as fertilizer.
My question is, what salt form of calcium would make the best fertilizer to provide calcium?
-Calcium Acetate
-Calcium Chloride
-Calcium Sulfate
-Other?
I'm thinking calcium acetate because in solution the calcium ions would separate from the acetate, allowing the plant to draw pure calcium, where as just using raw ground up eggshells, most of the calcium wouldn't be absorbed because of its extremely poor solubility.
If anyone has any input I'd highly appreciate it,
Thanks!
