Soil biology - Wikipedia, the free encyclopedia

Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, or edaphon is a collective term for all the organisms living within the soil. These organisms include earthworms, nematodes, protozoa, fungi, bacteria and different arthropods. Soil biology plays a vital role in determining many soil characteristics yet, being a relatively new science, much remains unknown about soil biology and about how the nature of soil is affected.

( I am not seeing anything about pathenogens )??? but I do see (SOIL LIFE and SOIL BIOTA)
But in hydroponics we dont deal with soil do we?

The soil is home to a large proportion of the world's biodiversity. The links between soil organisms and soil functions are observed to be incredibly complex. The interconnectedness and complexity of this soil ‘food web’ means any appraisal of soil function must necessarily take into account interactions with the living communities that exist within the soil. We know that soil organisms break down organic matter, making nutrients available for uptake by plants and other organisms. The nutrients stored in the bodies of soil organisms prevent nutrient loss by leaching.> Microbial exudates< act to maintain soil structure, and earthworms are important in bioturbation. However, we find that we don't understand critical aspects about how these populations function and interact. The discovery of glomalin in 1995 indicates that we lack the knowledge to correctly answer some of the most basic questions about the biogeochemical cycle in soils. We have much work ahead to gain a better understanding of how soil biological components affect us and the biosphere.

In balanced soil, plants grow in an active and steady environment. The mineral content of the soil and its heartiful structure are important for their well-being, but it is the life in the earth that powers its cycles and provides its fertility. Without the activities of soil organisms, organic materials would accumulate and litter the soil surface, and there would be no food for plants. The soil biota includes:
Megafauna: size range - 20 mm upward, e.g. moles, rabbits, and rodents.
macrofauna: size range - 2 to 20 mm, e.g. woodlice, earthworms, beetles, centipedes, slugs, snails, ants, and harvestmen.
Mesofauna: size range - 100 micrometres to 2 mm, e.g. tardigrades, mites and springtails.
Microfauna and Microflora: size range - 1 to 100 micrometres, e.g. yeasts, bacteria (commonly actinobacteria), fungi, protozoa, roundworms, and rotifers. ( still not seeing anything about viruses or pathenogens)

Of these, bacteria and fungi play key roles in maintaining a healthy soil. They act as decomposers that break down organic materials to produce detritus and other breakdown products. Soil detritivores, like earthworms, ingest detritus and decompose it. Saprotrophs, well represented by fungi and bacteria, extract soluble nutrients from delitro. The ants (macrofaunas) help by breaking down in the same way but they also provide the motion part as they move in their armies. Also the rodents, wood-eaters help the soil to be more absorbent.

(saprotroph [ˈsæprəʊˌtrəʊf]
n
(Life Sciences & Allied Applications / Microbiology) any organism, esp a fungus or bacterium, that lives and feeds on dead organic matter Also called saprobe saprobiont

Soil life table <<<<<<< hmm... SOIL BIOTA?

This table is a résumé of soil life, [1] coherent with prevalent taxonomy as used in the linked Wikipedia articles.


Bacteria are single-cell organisms and the most numerous denizens of agriculture, with populations ranging from 100 million to 3 billion in a gram. They are capable of very rapid reproduction by binary fission (dividing into two) in favourable conditions. One bacterium is capable of producing 16 million more in just 24 hours. Most soil bacteria live close to plant roots and are often referred to as rhizobacteria. Bacteria live in soil water, including the film of moisture surrounding soil particles, and some are able to swim by means of flagella. The majority of the beneficial soil-dwelling bacteria need oxygen (and are thus termed aerobic bacteria), whilst those that do not require air are referred to as anaerobic, and tend to cause putrefaction of dead organic matter. Aerobic bacteria are most active in a soil that is moist (but not saturated, as this will deprive aerobic bacteria of the air that they require), and neutral soil pH, and where there is plenty of food (carbohydrates and micronutrients from organic matter) available. Hostile conditions will not completely kill bacteria; rather, the bacteria will stop growing and get into a dormant stage, and those individuals with pro-adaptive mutations may compete better in the new conditions. Some gram-positive bacteria produce spores in order to wait for more favourable circumstances, and gram-negative bacteria get into a "nonculturable" stage. Bacteria are colonized by persistent viral agents (bacteriophages) that determine gene word order in bacterial host.
bacteriophages
bacteria-infecting virus: a virus that infects bacteria and may integrate into the genetic material of its host cell. Bacteriophages are used as vectors in gene cloning and have other biotechnological uses.

David Attenborough points out the plant, fungi, animal relationship that creates a "Three way harmonious trio" to be found in forest ecosystems, wherein the plant/fungi symbiosis is enhanced by animals such as the wild boar, deer, mice, or flying squirrel, which feed upon the fungi's fruiting bodies, including truffles, and cause their further spread (Private Life Of Plants, 1995). A greater understanding of the complex relationships that pervade natural systems is one of the major justifications of the organic gardener, in refraining from the use of artificial chemicals and the damage these might cause. <<<<<<<< the word for the day is ORGANIC

Recent research has shown that arbuscular mycorrhizal fungi produce glomalin, a protein that binds soil particles and stores both carbon and nitrogen. These glomalin-related soil proteins are an important part of soil organic matter.

The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing >>>>(except virus, which consists only from DNA/RNA covered by protein and lipids)<<<<<, and is often called the building block of life.[1] Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or multicellular (including plants and animals). Humans contain about 100 trillion (1014) cells.[2] Most plant and animal cells are between 1 and 100 µm and therefore are visible only under the microscope

This clearly states that a virus isnt a living organisim

There is no such thing as too many beneficial microbes. Your thinking of algae (micro flora). Typically we think of algae as green, but it comes in many colors (brown, red, yellow etc.). And yes algae will consume dissolved oxygen from the water, but you need a massive amount to do any harm by depleting oxygen. However on the other hand algae can wind up being a food source for pathogens, especially dying algae.

Ok so lets test your theory:

You told me you are using a product that adds Trich. H to your system and I am sure there is a recomended ammount that is to be used per gallon..... forget about the recomended amount and use 50 times that amount... let me explain to you what will happen.....
Your system will incubate 50 times the ammount of the fungus, plus the bacteria thats in your system will all need oxygen including the plants. Now this doesnt seem like its going to be alot but as the temperature of the root system warms, the rate of respiration of the root tissue also increases and more oxygen is required by the plant. This means that the dissolved oxygen in solution will be much more rapidly depleted and the plants can suffer from oxygen starvation for a period of time.
When this happens under continuing anaerobic conditions, plants produce a stress hormone - ethylene which accumulates in the roots and causes collapse of the root cells. Once root deterioration caused by anaerobic conditions has begun, opportunist pathogens will attack your plants.
Now let me key in on how a bacteria becomes a pathogen. Bacteria reproduce and its called bacteria conjugation, and this is basicly a transfer of of genetic material between bacteria and what happens is the donor bacteria transfers plasmids to the recieving bacteria, now most conjugtive plasmids cannot be transfered to a bacteria that has the same plasmids. Oh yeah let me mention that a plasmid is a double strand of DNA ( its not something thats not living) but it can replicate like a virus ( in a host ) but this doesnt mean that the bacteria is going to become a pathogen there are several other factors that will need to come into play such as, other bacterial secretions that can act as virulence factors, as well as bacterial numbers (via quorum sensing or the two component signal transduction pathway), toxins, change in environment, temperature, mutation ect..

I am not trying to be picky. Just letting you know. Organic and hydroponics never can happen. Organic must be grown in soil. Thats not to say the stuff you use is not organic. Just saying by rules.

[FLCRACKER1]

ORGANIC HYDRO CAN WORK.I've done it in verti gro stackes w pine bark .Nute were:neptune harvest fish,ocean solution,quantam growth microbes,seaweed.Grew mustard greens and squash,worked pretty well.

I am growing organically in my hydroponic system now. It can be done.

Here is a link to organic hydroponics

to get a usda 100% organic stamp ..... means you have to be 100% organic.

Organic hydroponics uses organic fertilizer. Conventional hydroponics cannot use organic fertilizer because organic compounds contained in hydroponic solution inhibit the growth of the crop roots, so it uses only inorganic fertilizer.

In organic hydroponics, organic fertilizer is degraded into inorganic nutrients by microorganisms in the hydroponic solution via ammonification and nitrification. The microorganisms are cultured with a method of multiple parallel mineralization. The culture solution can be used as the hydroponic solution.

The first synthetic hydroponic nutrient was first developed in 1859, hydroponics or water culture has been around since the 1500s. that's before there were synthetic and chemical fertilizers.

That's why I use the words synthetic nutrients and organic nutrients.

The difference is simply that organic nutrients, don't contain any harsh chemicals that are harmful to the environment. Organic nutrients allow a slow release of nutrients, enabling the plants to have a consistent source of food, and encourage healthy growth, of naturally occurring beneficial organisms (which aren't in synthetic nutrients). Which means you cant chemically burn up your plants.

I don't have a ppm meter and have never used one, I use a feeding schedule as recommend by the product brand, and it seems to work very well. All I check is the ph in my system. Growing hydroponically with totally organic nutrients is actually easier and cheaper than growing hydroponically with man-made chemicals by eliminating the need to balance different nutrient levels with ppm and pH in the water reservoir eliminates most of the problems associated with hydroponic growing.

In response to your statement:

Studies for establishing organic hydroponics have been conducted for long time. Kennedy Space Center had studied organic hydroponics for crop production in space.[2] It was necessary to develop the method to generate nitrate from organic fertilizer via ammonification and nitrification, because most of crops are nitrate-phylic but not ammonium-philic. It is easy to generate ammonium from organic fertilizer by saprophytic microorganisms. However it was difficult to degrade organic fertilizer to nitrate efficiently because the growth of nitrifying bacteria, such as the obligate chemolithoautotrophs Nitrosomonas spp. and Nitrospira spp., is particularly inhibited by the presence of organic compounds (Jensen 1950; Quastel and Scholefield 1951; Rittenberg 1969; Smith and Hoare 1977; Krummel and Harms 1982; Takahashi et al. 1992; Stutte 1996; Xu et al. 2000; Tomiyama et al. 2001).

Shinohara (1) invented the method to efficiently generate nitrate from in water. The method, multiple parallel mineralization, consists of three manipulations: small inoculation of soil microorganisms, addition of small amounts of organic fertilizer, and aeration. The mineralized solution can be used as the hydroponic solution and organic fertilizer can be added in the solution during cultivation. This is the first practical organic hydroponics technique that organic fertilizer can be added directly during cultivation.
