How many has used Yeast as a Fertilizer?

Yeast fertilizer

Soil science seems to be saying forget the manures and fertilizers and build the soil microbes instead. I recently went to the local bakers and asked for some fresh yeast. After a wait the young worker returned with a kilo of wrapped fresh yeast that she said would be best used within the...

Haven’t used yeast as a fertiliser. And in my time as a gardener never really heard about it so. I don’t think it’s a good idea. Yeasts do occur naturally in soils and plant matter and play a role in the microbial environment. But don’t really have any nutritional value. Stick to the usual methods of adding plenty of well rotted organic material to the soil. That really is the best way

Well this is an interesting subject.. done me a bit of research. The NPK value of yeast fertiliser is minimal. Much less than any other typical garden fertiliser. (I guess it’s better than nothing). It does have biostimulate properties. But no more than anything else. Some say that it has protective properties, but bakers yeast and brewers yeast has been demonstrated to cause some harm
in summary. It’s a nice fad but totally pointless

Here's another one.

It's not at all just about NPK. It's also about nutrient density. I suppose you think compost is useless too because it's not even considered a fertilizer There are many videos on youtube showing tests done with adding yeast water like the video above I posted that show big differences in plant growth. I guess according to you all those gardeners are lying. It has more to do with the bacteria added to the soil which is how the soil food web works. Also I've never seen any articles saying yeast is harmful to soil if you'd care to post some.

A good garden use for yeast is to kick-start composting. It doesn't take much. I mix it in barely warm water and dump it over the future compost. It seems to accelerate decomposition and, for some reason, attracts worms like crazy. I do it once and don't have to do it again until I add a lot of new stuff. The yeast lives over winter, but I doubt it does much work in freezing weather.


A good non-garden use for yeast is to mix some in barely warm water and dump it in sink, shower and tub drains. If you let it sit for a few hours, it magically eats the soap and oil film that coats pipes. It helps with grease that sneaks in kitchen sink drains, too.

I once looked in a tub drain pipe clean-out and could see 5 feet down the pipe. It was perhaps 40% closed by build up. After the yeast sat for a few hours and the tub was run, the pipes were clean like new.

I learned this trick from a person who cleans grease traps for a living.
