A Soil without microorganisms is just – Dirt.
Mycorrhizal fungi have co-evolved with plants and soils for millions of years. The bottom line is that mycorrhiza is to the roots of plants what chloroplasts are to the leaves of plants. Plants use leaves to fulfill their carbon needs and mycorrhizal fungi to attain nutrients and water.
Mycorrhizae is an anatomical structure that results from a symbiotic association between soil fungi and plant roots. In exchange for a ‘home’ the fungus provides numerous benefits to the host plant.
Myco’ means ‘fungus’ and rhizae’ means root and so the word Mycorrhizae means fungus- roots. In these mutually beneficial partnerships, the root of the host plant provides a convenient substrate for the fungus, and also supplies food in the form of simple carbohydrates. In exchange for this free ‘bed and breakfast’ the mycorrhizal fungus provides several benefits to the host plant. They form a beneficial symbiosis with the plant roots. In return for organic carbon from the plant, they scavenge phosphorus from much more soil than is explored by the plants’ roots, and deliver it to the roots.
MINDING YOUR “P” :
When applying a mycorrhizal inoculant at planting, it is important to avoid high levels of available phosphorus in the soil proximate to the target seed or roots. Readily available soil phosphorus in excess of approximately 70 ppm can prevent the mycorrhizal spores in an inoculant from breaking dormancy when in near contact with a live root. Since one of the primary natural functions of the mycorrhizal relationship is to access and mobilize phosphorus, the spores have been ‘programmed’ to delay activation in an abundant phosphorus environment. The propagules are not harmed and do not expire under such circumstances, however they remain dormant and colonization does not commence until the ambient phosphorus levels diminish. Insoluble forms of phosphorus that naturally occur in the soil do not contribute to this phenomenon.
Likewise phosphorus from organic or natural fertilisers such as soft rock phosphate, humates, fish fertilisers or kelp is not problematic. It is the realty available phosphorus, derived primarily from soluble (liquid) or fast-release fertilisers that contribute to this situation. The solution is to avoid high rates of P starter fertilisers. Remember that one of the primary reasons for high P in starter fertilisers is to overcompensate for the inefficiency of non-mycorrhizal roots. Once crop plants become colonised with mycorrhizal fungi, these high P levels are no longer required. Phosphorus fertillisers applied anytime 10 – 20 days after inoculation and colonization has occurred need not be restricted.
How do you tell if an application of mycorrhizal inoculant is working?
When trialing any change in program, be sure to leave a part of your crop untreated as a control.
Often the effects of mycorrhizal colonization will be obvious in early growth. The plants may be taller, have more foliage and larger root systems. If water is scarce, you may note less moisture stress compared to controls.
Sometimes the visual difference between the treated and control crop is less obvious but the yields are significantly better in the treated crops.. And occasionally, there will be no discernable difference at all.
In this last circumstance, it may be that the benefits lie entirely in savings via reduced inputs to get the same yields as without treatment. Capitalising on this may take some experimenting over several seasons.
