Ecosystem and apparatus to increase crop yield by treating agricultural land with algal by-products

1. A method to improve the yield of an acre of a crop having a growing season of less than one year, comprising the steps of

(a) providing an irrigation system to direct irrigation water on to the acre of the crop;

(b) providing an integration system to introduce a composition into said irrigation system;

(c) providing an ecosystem to produce algal by products, said ecosystem including

(i) a tank located out doors in an ambient temperature equal to or greater than sixty degrees Fahrenheit,

(ii) a volume of water in the tank to a depth in the range of twelve to thirty inches, said volume of water including an upper horizontally oriented surface,

(iii) at least one species of living algae in said volume of water,

(iv) at least one species of living bacteria coexisting with said algae in said volume of water,

(v) a nutrient input system to meter a liquid algal nutrient composition into the water during the day at a rate in the range of 0.001 to 0.05 ounces of nutrient composition per cubic foot of water in said volume of water, said nutrient composition including

(1) 6% to 15% by weight nitrogen,

(2) 5% to 35% by weight carbon,

(3) 1% to 6% by weight potassium, and

(4) 1% to 6% by weight phosphorous,

(vi) an algal by-product removal system including a vertically oriented drain tube construct having

(1) an open distal upper end positioned at said surface of said volume of water to skim an aqueous solution of algal by-products from said surface, and

(2) an open proximate upper end positioned below said distal upper end and exterior of said tank,

(vii) a water replenishing system including

(1) a supply of supplemental water,

(2) a nozzle positioned to deliver said supplemental water into said volume of water, and

(3) a reconstitution system to pressurize said supply to force said supplemental water out said nozzle into said tank at a rate in the range of two to twenty gallons per hour to produce

a current in said volume of water moving at a speed in the range of one-half to two miles an hour,

a generally circular flow pattern for said current in said tank, said flow pattern moving past said upper distal end of said algal by-product removal system, and,

two to twenty gallons per hour of said aqueous solution of algal by-products to be skimmed by said algal by-product removal system;

(d) metering during daylight hours with said nutrient input system 0.001 to 0.05 ounces of nutrient composition per cubic foot of water in said volume of water;

(e) injecting during daylight hours with said reconstitution system said supplemental water into said volume of water at a rate in the range of two to twenty gallons per hour to produce

(i) a current in said volume of water moving at a speed in the range of one-half to two miles an hour,

(ii) a generally circular flow pattern for said current in said tank, said flow pattern moving past said upper distal end of said algal by-product removal system, and,

(iii) two to twenty gallons per hour of said aqueous solution of algal by-products to be skimmed by said algal by-product removal system;

(f) skimming during daylight hours with said algal by-product removal system two to twenty gallons per hour of said aqueous solution of algal by-products; and,

(g) applying 250 to 400 gallons of said aqueous solution of algal by-products to the acre of crop by utilizing said integration system to introduce said aqueous solution of algal by-products into said irrigation water.
