The use of chemical fertilizers has increased plant growth and yields but their intense use creates plants that are less able to defend themselves against insects, microbial pathogens, and intrusive weeds. To combat these problems insecticides, fungicides, and herbicides have been developed. While initially protecting the crop, the use of these toxic chemicals sets off a cycle of resistance to the chemicals. The resistance produces the need for increased applications of more powerful chemicals. The environmental impact from the use of these chemicals is an increasing concern. High quality humus compost offers a solution to many of these concerns.
Fishnure is an organic fertilizer and soil conditioning supplement made from fish manure. It is made in a special process that adds nutrient capturing inoculates and clay during the decomposition of the organic matterials. The clay provides microscopic particles to which organic particles bind. The clay particles also provide a perfect environment for the microbial life. The fish manure used in the process is the solid waste from a high protein diet excreted by fish in a raceway environment where the solid waste can be captured and removed quickly from the water before nutrients can leach from the waste.
The clay used in the process is from the rich soil of the Mississippi river delta. In addition the clay comes from the bottom of discontinued catfish ponds that grew intensive populations of catfish for over 12 years. The organic wastes were not removed from the ponds and as a result added beneficial nutrients to the clay in the bottom of the ponds. In recent years many fish ponds have been converted back to growing soybeans and these pond acres have exceptional yields due to the added nutrients in the soil.
The carbon source used to create the proper carbon to nitrogen ratio for the process is either oat straw.
The resulting Fishnure organic fertilizer has no fishy smell. It has a moist putty-like consistency and smells like freshly tilled soil. It readily mixes with water and provides basically the same nutrients as those provided in an aquaponic environment where no additional nutrients are needed for plant growth.
