Lately we often hear that most of Indonesia’s soil is sick, due to lack of nutrients. The main cause is the use of excessive chemicals so that the element of organic matter in the soil is reduced. One thing that is predicted to improve agricultural soil is the use of microorganisms as ‘fixers’.
Microbes or microorganisms are living organisms that are so small that they cannot be seen with the naked eye. Some examples of microbes in our daily life are fungi, bacteria, and viruses. In agriculture, usually the presence of microbes is considered a bad connotation, because it brings diseases that are harmful to plants. However, not all microbes are harmful, the microbes below can be useful for plants.
Microbes can function as fertilizers, pesticides, biodecomposers, growth stimulants, and reduce harmful chemical elements from the environment. If you have a garden at home, you can really use the following microbes to support plant growth in your garden.
Usually located in the roots of bamboo plants, this one fungus lives from the rest of the organic material around it. Trichoderma often found in dry form, and has been traded widely. The results of several studies show, Trichoderma can function as Biopesticides, Growth Stimulating Substances (ZPT), and decomposers.
Utilization Trichoderma can be done by spraying mushrooms Trichoderma powder that has been dissolved in water to plant roots regularly. Apart from this, you can also make compost from bamboo leaves, or mix the planting media used with soil from bamboo plant roots.
Famous for its symbiosis with legume plants that can produce root nodules. Rhizobium are soil bacteria that can absorb nitrogen which is beneficial for plants. In addition, these bacteria can produce growth hormones in the form of IAA or indole acetic acid which stimulates the growth and elongation of cells in plants. Bacteria Rhizobium Currently it has been widely commercialized. Its use is more or less the same as Trichoderma by pouring out a solution Rhizobium to the planting medium on a regular basis.
3. Bacillus subtilis
Bacillus subtilis is one of the phosphate solubilizing bacteria whose properties are effective in agriculture. As we know the element phosphate is indispensable in agriculture. Especially plants that produce flowers and fruit such as cucumbers, tomatoes, chilies, eggplants, beans, and others. Phosphate elements can form proteins that plants use to form their organs. Apart from being a biofertilizer, Bacillus subtilis can stimulate plant growth and protect plants from disease. Some of the diseases that have been tested are rust, downy mildew, tuber rot, and many others. Applications can be done by mixing with the planting medium or coating the seeds to be planted.
In addition to the above microbes, there are also many other microbes that have benefits
