Introduction
Aerobically made compost tea offers ecologically sustainable and economically viable answers to problems faced by persons engaged in agriculture due to chemical build ups in fields and in ground water sources. Aerobic compost tea contains a rich diversity of fungi, living bacteria, protozoa, and more that are ready to go to work in the soil and on the leaves. Compost tea can help the farmer to overcome the chemicalization problems. The benefits include healthier plants, increased yield, less irrigation necessary, and more resistance to stress and drought conditions.
Background:
Many persons engaged in agriculture have grown accustomed to the idea that we need to use pesticides, fungicides, weed killers, etc. The idea is to kill any bad pest or disease to get rid of it.. What we fail to realize, is that there is also an enormous amount of beneficial organisms that goes on in the soil and on the leaves. By killing the bad pest with pesticides we also kill off many of the beneficial organisms as well. Over time this process kills off more and more of the beneficial microbes. The addition of these beneficial microbes back into the soil and onto the leaves using aerobically made compost tea replenishes this microscopic army, so it can go to work for you.
Contemporary History of Compost Tea:
For many years, farmers made their own compost or manure tea by placing a bag of compost in a barrel and letting it sit for a while. This mixture was anaerobic and often smelly. More recently, a new technology has been developed, where the barrel has been replaced by a “brewer” that oxygenates the water. This oxygenation of compost produces microbes that are ready to go to work in the soil. This aeration process has been very successful and is differentiated from the old fashioned non-aerated tea
Why Compost Tea:
High quality, aerobic, compost tea is made from diverse sources of composts such as worm casting and other natural ingredients. The “brewer” produces beneficial microbes from these composts etc. and with the addition of food sources for the microbes to grow on, will multiply these microbes many times over. In order for beneficial aerobic microbes reproduce and grow oxygen levels are kept at a high level. These microbes will provide a new microbial population in the soil and on the leaves. Aerobically made compost tea can be the cornerstone of your fertilization program. Aerated compost tea is great for acidic loving shrubs such as blueberries. The microbes in compost tea have a variety of jobs including the following:
Beneficial Microbes Jobs In the soil:
- Aerated compost tea contains the microbes that will significantly enhance the availability of the nutrients already in the soil.
- Aid in breaking down crop residues, reducing sites that over-winter disease.
- In the soil the beneficial microbes are natural predators against disease organisms.
- These beneficial organisms have many jobs including converting and releasing nitrogen into the soil. As time goes on the microbes are not producing as much and more and more nitrogen is needed. The beneficial microbes also hold nitrogen in the soil, but when they die off, the nitrogen as well as other nutrients such as calcium, are no longer held in the soil and leach away from where they are needed resulting in the contamination of ground water, rivers, lakes, etc. The chemicals added to the soil are also leached away resulting in the contamination of our precious natural resources.
- The beneficial microbes help add organic matter back into soil as they work.
- The beneficial microbes have a large variety of jobs including retaining nutrients and making available nutrients as the plant needs them. help in the release of soil nutrients – especially Phosphorous and minors.
- Application of aerated compost tea will help replace the beneficial microbes lost if fungicides have been used and/or certain insecticides.
- Microbes in compost tea helps hold nutrients and significantly reduce or eliminate leaching.
Beneficial Microbes Jobs On the leaves:
- Beneficial microbes on the leaf surfaces protect the leaf surfaces by occupying the space that could be taken over by pathogens. This will form a physical barrier to the pathogens and protect the leaf surfaces.
- Symbiotic relationship with leaves – (they feed each other).
When to Apply
Compost tea is a very perishable biologically active liquid concentrate. This very perishable concentrate of living organisms must be used within 4-6 hours of brewing.. Aerobic compost tea must be applied in the morning while it is cool or the evening so the microbes get a chance to establish before it gets too hot in the blazing the sun. If rain is in the forecast it is important to apply compost tea on the leaves at least 6 hours before a rain. Otherwise the microbes may be washed off before they can stick on the leaf. For a soil application, applying the compost tea during or just before a light rain would be good thing.
Aerobic compost tea is not a fertilizer. It is a part of the whole soil maintenance program. It contains the biological microorganisms that will significantly increase the benefits of the nutrients already in the soil. It takes time for the beneficial microbes in the soil to multiply and grow, for this reason applications are best done the previous fall for a crop in the spring, although spring applications are still beneficial if it was not done last fall.
How to apply:
With the above background, it is not hard to realize that there are certain principles that must be kept in mind during application. Oxygen levels must be kept up until application. There is some particulate matter in the tea, so larger filters (>25 mesh) and therefore larger nozzles are required. A diaphragm pump is recommended if possible. Applying the tea with a sprayer containing pesticide residues, may nullify the application and too much pressure will harm the organisms as they are sprayed onto the leaf surface. These things need to be worked out ahead of application time so that the fungi and bacteria are not screened out or damaged too much in application. Apply with equipment that will ensure uniform coverage.
