I made Compost tea for the first time about a week ago. My plants responded well to it. How often can you apply it to your garden?
2 weeks of brewing with an airpump is way too long .... you should brew the compost tea for no longer that 48hrs ... I use an aquarium heater and set the temp to 20 degrees C, and brew for 24 hoursbaldwinshere wrote:Hi
I'm doing trials using a range of compost teas on tomatoes for my Degree Dissertation and am feeding weekly so will keep you posted about the results if your interested to see the effects.
I'm feeding weekly as my Compost teas are only weak, 1kg of solid to 30ltrs of water, brewed over two weeks. As your aware the more solids the stronger the mix but that may result in over feeding which can damage plants. Compost tea nutrient levels are tricky like that
Also it is better to keep the Compost tea aerated as anaerobic teas could develope fungal disease spores and harmful bacteria in the water which could harm your plants
Hope that helps a little
when brewing compost tea, you are not brewing fertilizer .... you are brewing beneficial microbes ....imafan26 wrote:We did a trial on compost tea. We grew lettuce and measured leaf length. One group was the control and had osmocote only, the second group used aerated compost tea and the third non-aerated tea. The teas were applied weekly. The trial lasted 5 weeks and leaf growth was measured weekly.
Tea was aerated for 48 hours and had to be used within 4 hours after aeration was discontinued
non-aerated tea was steeped for 7 days. It was covered with a screen to keep mosquitoes out.
Osmocote group did the best
The second fastest group was non aerated tea
The theories were
1. The microbes in the aerated tea died off faster once aeration stopped
2. Nitrogen is the most difficult nutrient to supply organically
a. aeration could accelerate nitrogen losses to the air.
b. Organic nutrients release slowly over time, lettuce is a short crop
and uses relatively more nitrogen.
here is a writeup/comparison of AACT and EM1 .... I have never tried EM1 and never heard about it until reading about it on your post ...imafan26 wrote:I don't know what kind of compost was used in the brew. That was not reported in the study. I know that they were talking about adding EM1 to the tea, but I don't know if it was actually done.
