What specific natural plant nutrient sources or plant growth-promoting sources, such as BIOSTIMULANTS, BIOFERTILIZERS, etc., would you use for starting cultivating tropical crops like corn, sorghum, millet, peanuts, tomatoes, and onions in a middle scale production in a tropical country as Simbabwe, where chemical fertilizers are economically not afordable or either unavailable, but where some animal dung is accessible?
How economically successful is it which commercially available mycorrhiza to use or other microorganisms of the soil microbiome with similar benefits such as PGPR (plant growth-promoting rhizobacteria), PGPF (plant growth promoting fungi), PGPM (plant-growth-promoting microorganisms), as well to use seaweed, algae stimulants or verimcompost?
Vermicompost or worm castings are excellent biostimulants.
If leaves are raked around a tree and watered it creates a habitat for worm activity.
The castings which accumulate are wonderful to start plants.
This material can placed in the planting hole.
Worms also appreciate animal bedding with manure.
The wormed and composted material will concentrate the plant trash making its movement more manageable.
