Microbiol compositions for uniform application to dry soil to provide a cover crop and to improve soil aggregation are disclosed. The compositions comprise flocculant-producing photosynthetic microorganisms, especially algae, in a dormant or resting stage mixed with a dry, particulate, water dispersible carrier. Methods for the production and use of the compositions are also disclosed. |

DETAILED DESCRIPTION OF THE INVENTION Reference will now be made in detail to the presently preferred embodiments of the invention, which, together with the following examples, serve to explain the principles of the invention.
The present invention relates to microbial compositions for application to soil to provide a cover crop and to improve soil aggregation.
The compositions comprise a dry, flowable mixture of flocculant-producing photosynthetic microorganisms in a resting stage and a dry, particulate, water dispersible carrier.
The compositions are capable of uniform application to dry soil to provide a cover crop of the microorganisms in a vegetative stage and to improve soil aggregation through the action of the flocculant.
The compositions may also include other materials in dry, particulate form, such as various plant nutrients, especially fertilizers.
In some instances, it may also be desired to provide nutrients for the photosynthetic microorganisms in the composition, for example, when the composition is being applied to nutrient-poor soil.
The photosynthetic microorganisms of the present invention are any flocculant-producing microorganisms that utilize chlorophyll to convert carbon dioxide, nutrients, and inorganic nitrogen into cell substance by means of energy derived from sunlight.
The prime examples of such microorganisms are algae, particularly green and blue-green algae, which are the preferred microorganisms for compositions of the present invention.
However, the teachings of the present invention may be adapted by those of ordinary skill in the art to the preparation and use of compositions containing other flocculant-producing photosynthetic microorganisms, where the photosynthetic or flocculant-producing capabilities are introduced by any of the various techniques of genetic manipulation.
In a preferred embodiment, the compositions contain one or more strains of green or blue-green algae.
Generally, it is preferable to use a mixture of strains so that the composition may be used on a wide variety of soil types
