The SoilSlide2
Soil is a living organismRespect the circle of Life(micro) organismsbacteria/mold/fungi/yeasts/amoebabugs/nematodes/earth wormsvegetablesGood Life: BALANCESlide3Slide4
Micro-organisms …..Convert Organic matterinto Nutrients and MineralsConditioning the SoilGenerating HeatAerobic: in the presence of air (oxygen)Anaerobic: in the absence of airfermentationSlide5
Some micro organisms are facultative anaerobic or aerobicThe circumstances determine how they behaveExamples: Lactobacillus sp.Produce e.g. lactate (yoghurt, sourdough), acetate (vinegar) and some ethanol (alcohol).Slide6
Aerobic Micro-organisms …..(woodstove full blast)BacteriaFungusBugsExamples: compost, well-aerated soilMore complete breakdown of organic matter(ultimately to carbon dioxide, water and minerals NO3-, SO42-, PO43-) With high energy production (heat)Slide7
Anaerobic Micro-organisms …..(woodstove during the night)YeastBacteriaExamples: Sauerkraut, yoghurt, cheese, Bokashi, bread, beer, wine, free-living bacteria N-fixation, methane bacteriaPartial breakdown of organic matter with many different nutrients producedAs well as minerals NO2-, NH3, H2S, SLow energy release (most energy still in
nutrients
)Slide8
Garden soil needs both Anaerobic micro-organisms …..mainly to provide a range of organic nutrients to the roots(BUT some can produce less favourable substances)…..and Aerobic micro-organismsmainly to provide heat (energy) and
minerals
long-term
stabilisation
of the soil temperatureSlide9
Anaerobic fermentation -produces nutrients-leaves organic matter largely unchanged to the eye-fermented organic matter can be composted more easily by Aerobic organismsSlide10Slide11
How can we promote a healthy balance in terms of soil micro organisms: bacteria?Reduce ‘bad’ bacteria: cause diseaseIncrease ‘good’ bacteria: provide nutrients and protection against disease PROBIOTICSGood and bad compete partly for the same nutrients: add more ‘good’ and the ‘bad’ will disappear!Slide12
Lactobacillus sp.ProbioticAlso for plantsFound in: Sauerkraut, yoghurt, cheese, BokashiSlide13
Lactobacillus sp.Easy to produce and to applyto soil and plantsFound dormant on many plants and seedse.g. rice, wheat, barley, oatsHarvest bacteria/sporesReviveMultiplyStore/ApplySlide14
Lactobacillus sp.CAVEAT!!MPI fumigates imported foods such as rice (unless from Oz)MeBr kills bacteria and sporesMeBr contributes to the ozone holeUnknown whether treated food affects your healthSlide15
Lactobacillus sp.Harvest bacteria/sporesWash grains with non-chlorinated water and collect first wash(‘whitish’ water: starter)or make sourdough starter Contains some bacterial and fungal sporesSlide16
Lactobacillus sp.Revive bacteria/sporesLet starter sit under cover of cloth (flies)For about a weekWarm-ish spotSmells a little sourPrecipitate-liquid-top layerSlide17
Lactobacillus sp.Multiply bacteria/sporesCollect the starter liquidMix 1+10 with milkLet starter sit under cover of cloth (flies)Or in a fermentation potFor about a weekWarm-ish spotSmells cheesySlide18
Lactobacillus sp.Multiply bacteria/sporesTop layer ‘Curd: Cheese’Middle layer ‘Whey+bacteria: green-ish’= concentrated LAB serumBottom layer Slide19
Lactobacillus sp.Slide20
Lactobacillus sp.Apply/Store Collect middle layer = conc. LAB serumDilute (ncw) LAB serum 1:20|Dilute (ncw) LAB application solution (1:20)Apply before sowing, when planting, transplanting, spraying of diseased plantsSlide21
Lactobacillus sp.Apply/Store This is the workhorse of the beneficial bacteria. Many other uses:Foul odors, clogged drains, septic tanks, cheaper pig/chicken/etc farming, aquaculture, ponds, drink, ointment Slide22
Lactobacillus serumLactic-acid producing bacteria (LABs) are known to have various beneficial qualities such as anti-tumour activity, reduction of serum cholesterol, alleviation of lactose intolerance, stimulation of the immune system, enhancement of resistance against pathogens and prevention of traveller’s diarrhoea (Aimutis 1999; Reid 2006).Slide23
