There are plenty of things from around the house that can be used to make great potassium rich fertilizers. Wood or fireplace ash is a very good option for boosting the potassium in the soils, just be careful and test the soil first to make sure the soil isn't already alkaline, as fireplace ash will make the soil even more alkaline and if used near any acid loving plants, may deprive them of the acidity that they need.
Used coffee grounds also make for a good fertilizer that has a good amount of potassium in it, again being careful not to overdo it.
Perhaps one of the best things you can do is have your own composting area. Table scraps, paper, dead / dying plant materials all go into it and overtime will create a great fertilizer that your plants will go crazy for. Hope this helps.
Yes
Potassium is the element that used to be first to make fertilizer.
Yes, potassium nitrate can be used as a fertilizer in agriculture.
That elements found in soil fertilizer are nitrogen, phosphorus, and potassium.
There are about seven kinds of fertilizers:Organic Fertilizer,Inorganic Fertilizer,Nitrogen-Based Fertilizer, Phosphorus-Based,Fertilizer,Potassium-Based Fertilizer, Liquid Fertilizers and Solid Fertilizers. Whirlston fertilizer machines can make most of them.
Fertilizer often contains minerals including iron and potassium.
potassium choloride
That depends on what the fertilizer for. Nitrate promotes rapid growth, phosphate promotes other things.
Potassium
Commercial potassium fertilizer utilizes potassium carbonate - no idea what this gluconate compond might do to plants - recommend against it, as this is a human dietary supplement and wasn't tested on plant roots etc.
The three numbers on a bag of fertilizer indicate the percentage of nitrogen, phosphorus, and potassium available. So in the case of 0,0,60 fertilizer, there is 60% potassium available with no nitrogen & phosphorus.
a simple fertilizer is a fertilizer with only consists if the nutrients N- Nitrogen P- Phosphorous K- Potassium
