Soils can be characterized according to their indigenous microflora which perform putrefactive, fermentative, synthetic and zymogenic reactions and processes. In most soils, these functions are going on simultaneously with the rate and extent of each determined by the types and numbers of associated microorganisms that are actively involved at anyone time. In disease-inducing soils, plant […]
From the time humans made the transition from hunter-gatherer societies to settled communities with a local agricultural base, the need has existed to improve the quantity and quality of our fruits, vegetables and grasses. Initial steps in this age-old undertaking included better selection of varieties for controlled propagation and improving agronomic practices related to tilling, […]
The desired effects from applying cultured beneficial and Effective Microorganisms to soils can be somewhat vari able, at least initially. In some soils, a single application (i.e., inoculation) may be enough to produce the expected results, while for other soils even repeated applications may appear to be ineffective. The reason for this is that in […]
These soils are dominated by a microflora that can perform useful kinds of fermentation, i.e. , the breakdown of complex organic molecules into simple organic substances and inorganic materials. The organisms can be either obligate or facultative anaerobes. Such fennentation-producing microorganisms often comprise the microflora of various organic materials, i.e., crop residues, animal manures, green […]
These soils con tain significant populations of microorganisms which are able to fix atmospheric nitrogen and carbon dioxide into complex molecules such as amino acids, proteins and carbohydrates. Such micro organisms include photosynthetic bacteria which perform incomplete photosynthesis anaerobically, ce1tain Phycomycetes (fungi that resemble algae), and both green algae and blue-green algae which function aerobically. […]
The microflora of disease-suppressive soils is usually dominated by antagonistic microorganisms that produce copious amounts of antibiotics. These include fungi of the genera Penicillium, Tricho derma, and Aspergillus, and actinomycetes of the genus Streptomyces. The antibiotics they produce can have biostatic and biocidal effects on soil-borne plant pathogens, including Fusarium which would have an incidence […]
In disease-inducing soils, plant pathogenic microorganisms such as Fusarium fungi can comprise 5 to 20 percent of the total microflora. If fresh organic matter with a high nitrogen content is applied to such a soil, incompletely oxidized products can arise that are malodorous and toxic to growing plants. Such soils tend to cause frequent infestations […]
Soils can be characterized according to their in indigenous microflora which perform putrefactive, fermentative, synthetic and zymogenic reactions and processes. In most soils, these functions are going on simultaneously with the rate and extent of each determined by the types and numbers of associated microorganisms that are ac tively involved at any one time. Pro-Soil […]
The photosynthetic bacteria, which perform incomplete photosynthesis an aerobically, are highly desirable, beneficial soil microorganisms because they are able to detoxify soils by transforming reduced, putrefactive substances such as hydrogen sulfide into useful substrates. This helps to ensure efficient utilization of organic matter and to improve soil fertility. Photosynthesis involves the photo catalyzed splitting of […]
The processes of putrefaction, fermentation, and synthesis proceed simultaneously according to the appropriate types and numbers of microorganisms that are present in the soil. The impact on soil quality attributes and related soil properties is determined by the dominant process. The production of organic sub stances by microorganisms results from the intake of positive ions, […]
