Let me start by saying compost tea is a generalized term. No two compost teas will ever be the same, nor will they ever provide the same benefits. In nature you can't expect something from nothing, so the quality of your compost tea is heavily dependent on what goes into your compost. At Leaf sweets Microgreens the only thing that goes into our composting bins is 100% organic Microgreen tray waste (Coconut Coir, microgreen cutting scraps and root systems).
From there, the worms take over and produce worm castings (which you already use in your garden). The coconut coir holds more oxygen than conventional soils which makes for an excellent breeding ground when it comes to beneficial microbes. These microbes or bacteria are beneficial for the soil, they help decompose organic waste and transform it into nutrients ready for plant consumption. These are Anaerobic and Aerobic Bacteria, both have their place in soil and perform separate tasks.
What you will gain from using compost tea? Mycorrhizae Fungus - Mycorrhizal fungi have existed since the first plants appeared on dry land more than 450 million years ago. They form a close symbiotic relationship with plant roots.
Mycorrhizae form a network of filaments that associate with plant roots and draw nutrients from the soil that the root system would not be able to access otherwise. This fungus-plant alliance stimulates plant growth and accelerates root development.
One kilometer of hypae (fine filaments) may be associated with a plant growing in a one-liter pot and it can access water and nutrients in the smallest pores in the soil. It also makes the plant less susceptible to soil-borne pathogens and to other environmental stresses such as drought and salinity .In return the plant provides carbohydrates and other nutrients to the fungi. They utilize these carbohydrates for their growth and to synthesize and excrete molecules like glomalin (glycoprotein).
However, in soil that has been disturbed by human activity, the quantity of mycorrhizae decreases drastically so that there are not enough of them to produce a significant benefit on plant growth and health, hence the importance to compensate for this by adding compost tea!
Humic Acids - Humic acid can be defined in only two words i.e. Plant Catalyst. It is an organic growth stimulator for plants. It works by bringing increment in plant’s nutrient intake and metabolism. In this way, it improves development of plants. Humic acid is also found to be a major constituent of natural matters found in nature’s almost all fertile soils.
Disease and Weather Resistance - All of these processes combined provide increased resistance to Drought, Disease (Root Rot), Mildew and Salinity in the soil.
Organic Fertilizer - Compost tea generally has a low N.P.K value but, it does have some and the key here is that this fertilizer is very easily absorbed by the plants, While using compost tea it is suggested to use your normal fertilizer at about half strength for the first week after applying. The tea has an effect on bioavailability of fertilizers and therefor you run the risk of getting nutrient burn on your plants with normal-heavy fertilization.
So there it is, a high level overview of how compost tea can be of great benefit to your garden, house plants or medicinal plants! We offer compost tea, right here locally made in New Brunswick, Canada. Just click here ---> Leaf Sweets Compost Tea Cheers!
