Sesbania is a leguminous green manuring crop. Its decomposition increased soil microbes. Which microbes availability is higher rather rhizobium, in sesbania, decomposed soil, ?Do that microbes have any positive impact in salty soil?
Sesbania decomposition enriches the soil with a variety of beneficial microbes, beyond just Rhizobium. Key microbial groups that increase include:
Actinobacteria: Break down complex organic matter and are beneficial in salty soils by improving soil structure and nutrient availability.
Bacillus species: Tolerant to saline conditions, they promote nutrient cycling, plant growth, and help suppress soil pathogens.
Pseudomonas species: Adaptable bacteria that aid in plant growth and are often salt-tolerant.
Arbuscular Mycorrhizal Fungi (AMF): These fungi enhance water and nutrient uptake, particularly phosphorus, which is essential for plants in saline soils.
Benefits in Saline Soils
These microbes enhance nutrient availability, improve soil structure, and increase plant salt tolerance, all of which contribute to better soil health and plant growth in salty conditions.
Sesbania upon incorporation in the main field as in-situ green manuring will have a very good impact on overall soil health. Upon decomposition it provide good amount of organic material for the micro which is much essential for microbial development. Thus ultimately increases the soil micrflora.
Only care to be taken is sesbania should be incorporated when the plants are at grand growth stage or during initiation of flowering and sufficient moisture should be there in the soil for proper decomposition. if these two are taken care overall soil health will be improved
