Bio-enriched soil technologies (BEST)
A bio-enriched soil and method of production is presented. If water supply is scant, bio-enriched soil technologies (BEST) are able to attract, store, and transport water and nutrient molecules to a plant in a controlled way. If the water or nutrient resources are excessive, BEST can release the excess and supply only what is needed. Hence, bio-enriched soil can function in climates in which crops normally are under stress by increasing the bioavailability of nutrients and water.
1. A method of enhancing soil by modulating water and nutrient availability in the soil comprising:
measuring moisture in the soil to determine soil water balance;
measuring a surface tension of the soil and decreasing the surface tension of the soil to below about 72 mN/m if the surface tension of the soil as measured is equal to or above 72 mN/m;
modeling soil environment using a COMSOL® model to determine changes in the soil water balance in response to adding cactus mucilage to the soil;
adding an amount of cactus mucilage to the soil based on results obtained in the COMSOL model; and
subsequently adding an amount of at least one inorganic compound to the soil to produce a bio-enriched soil.
2. The method of claim 1 , wherein the at least one inorganic compound is at least one macronutrient, at least one micronutrient, or combinations thereof.
3. The method of claim 1 , wherein the cactus mucilage is obtained from Opuntia ficus indica (OFI).
4. The method of claim 1 , wherein the cactus mucilage is present in the bio-enriched soil in a random configuration.
5. The method of claim 1 , wherein the cactus mucilage is present in the bio-enriched soil in a linear or a three-dimensional (3D) configuration.
6. A method of modulating water and nutrient availability in soil comprising:
measuring moisture in the soil to determine soil water balance;
measuring a surface tension of the soil and decreasing the surface tension of the soil to below about 72 mN/m if the surface tension of the soil as measured is equal to or above 72 mN/m;
modeling soil environment using a COMSOL® model to determine changes in the soil water balance in response to adding cactus mucilage to the soil;
adding an amount of cactus mucilage to the soil based on results obtained in the COMSOL model; and
subsequently adding at least one nutrient to the soil to produce a bio-enriched soil;
wherein the cactus mucilage stores or releases the water and the at least one nutrient in response to soil conditions.
7. The method of claim 6 , wherein the cactus mucilage is obtained from Opuntia ficus indica (OFI).
8. The method of claim 6 , wherein the cactus mucilage is present in the bio-enriched soil in a linear configuration.
9. The method of claim 6 , wherein the cactus mucilage is present in the bio-enriched soil in a random configuration.
10. The method of claim 6 , wherein the cactus mucilage is present in the bio-enriched soil in a three-dimensional (3D) configuration.
