摘要:
The present invention relates to a method of enhancing growth conditions for plants by growing the plants in soil containing, in proximity to the plant roots, both a phosphorus source and at least two strains of the fungus Penicillium, particularly P. bilaiae, more particularly strains NRRL 50162 and NRRL 50169.
摘要:
The present invention relates to the use of a bacterium having an high indole-3 -acetic acid (IAA) content for solubilizing phosphate rock (PR) in the ground, wherein said bacterium is obtained by transformation with a gene encoding an agent able to increase the IAA content.
摘要:
A horticultural growing medium is made up of composted bark, a carbon-based fibrous material, a hydrophilic polymer, sea solid , and beneficial bacteria/fungicide. The materials are formed into a solid substrate having structural stability, with both micro and macro interconnecting pores. The addition of a controlled release fertilizer provides for a perfect combination of nutrients, water retention, and pest and fungus control.
摘要:
This invention includes uses and methods of preparing phosphites and/or hypophosphites (and their polymeric forms and/or their salts) and phosphite-based agrochemicals (fertilizers and biocides) from phosphate or other naturally occurring or synthetic phosphorus sources using anaerobic microbial fermentation. The fermentation process produces both a liquid and solid phase phosphite/hypophosphite salts which can be used as an agrochemical product.
摘要:
The subject invention concerns materials and methods for providing or enhancing nitrogen fixation in plants. The invention provides for the use of nitrogen fixing bacteria that are isolated from nitrogen efficient plants. Plants for which enhanced nitrogen fixation is desired are inoculated with an effective amount of nitrogen firing bacteria of the invention. In an exemplified embodiment, the bacteria is Klebsiella Kp342. The subject invention also concerns means to increase the number of free-living nitrogen-fixing bacteria in plants. Mutants of beneficial endophytic bacteria that are resistant to plant defense responses can be used to colonize a plant in numbers higher than a wild type or a non-mutated bacteria can colonize a plant. The higher number of bacteria colonizing the plant provide for more nitrogen fixation for the plant. The subject invention concerns methods for producing non-leguminous plants that are capable e of utilizing atmospheric nitrogen by colonization with a nitrogen fixing endophyic bacteria that is resistant to plant defense responses. The subject invention also concerns the plants produced by the subject method. The subject invention also concerns methods for producing the mutant endophytic bacteria. The subject invention also concerns the mutant endophytic bacteria produced using the subject methods.
摘要:
The invention is directed to a system for promoting microbiological nitrogen fixing activity during cultivation of a plant including the steps of applying a microbial culture including nitrogen fixing strains to the plant and or surrounding soil, applying a carbon based medium to the plant and or surrounding soil for the promotion of microbial growth, periodic monitoring for the presence of endophytic or symbiotic microbes within the plant or surrounding soil or for the presence of nitrate or nitrogen within the plant and reapplication of the carbon based medium when the nitrogen in the plant reaches a predetermined level or the concentration of the endophytic or symbiotic microbes reaches a predetermined level.

摘要:
The present invention relates to a plant nutrient reduction system comprising the application to plants of a microbially enhanced inorganic fertilizer composition wherein said application results in plant growth and yield comparable to the application of substantially greater amounts of a non-microbially enhanced fertilizer composition.
