Cultivation of plants requires soil microorganisms for soil fertility in agriculture. Soil microorganisms have different types in various climates and locations. In some regions, the existence of these types of soil microorganisms is sufficient. However, in some cases, overall, the function of soil microorganisms for soil fertility has not been able to support agricultural production needs as expected. In such cases, farmers need enrichment from outside organisms. Farmers can do this through biodiversity fertilizer.
The function of soil microorganisms for soil fertility can be decreased. There are several factors that can influence that. One of the factors that caused the decline in land microorganism was the selection of agricultural commodities. Farmers choose commodities that have high economic value. Or farmers try to meet market share from abroad. These agricultural commodities are not the result of natural selection from the subsystem. These agricultural commodities can be engineered by organisms or from outside the subsystem area.
Soil microorganisms for soil fertility: Mutual symbiosis
Agricultural commodities that are not the result of natural subsystem selection can cause ecosystem shocks. These ecosystem changes can occur in extreme ways. Farmers can prevent extreme ecosystem changes. One way to prevent extreme ecosystem changes is to use beneficial soil organisms. However, farmers must use this native soil organism proportionally.
Farmers must choose microorganisms that are capable of symbiotic mutualism. These microorganisms must be mutually beneficial with their host plants. And these microorganisms have a competitive nature with other organisms around them. If the farmer is able to choose this organism, the ecosystem shock is not expected to occur.
For example, the inoculation of microorganisms Rhizobium is capable of tethering air N2. Rhizobium can symbiosis with Leguminosae plants by forming root nodules. In this symbiosis, legume plants as host plants and Rhizobium bacteria as symbionts. Host plants supply energy to support the N2 tethering activity by Rhizobium. Furthermore, the host plants utilize N from the process of microorganisms to support growth and production.
Likewise, Mikorisa microorganisms are able to carry out mutual symbiosis with their host plants. Micorisa microorganisms live on plant roots. These microorganisms can increase nutrient uptake by plants.
Farmers should be able to choose microorganisms that have mutual symbiotic properties as mentioned above. The population of all microorganisms must be able to support the cultivation carried out by farmers. Farmers can fertilize using biodiversity fertilizers to meet the availability of microorganisms. Biodiversity fertilizers also have the benefit of providing types of functional soil microorganisms that are not yet available in the garden area.
