| 发明名称 | Monitoring and control of soil conditions | ||
| 摘要 | Various methods and systems are provided for monitoring and control of soil conditions. In one example, among others, a method includes obtaining aqueous samples from suction probes within a soil substrate and analyzing the aqueous samples to determine a chemical composition of the soil substrate. Amounts of an additive may be determined to adjust the chemical composition of the soil substrate. In another example, a method includes installing a suction probe within a soil substrate; drawing a vacuum to induce hydraulic conduction of aqueous solutions from the soil substrate; extracting an aqueous sample; and analyzing the aqueous sample to determine a chemical composition of the soil substrate. In another example, a method includes obtaining a composition of a fertilizer solution (FS) supplied to a soil substrate and a chemical composition within the soil substrate; determining nutrient utilization, and providing an amount of additive to produce a subsequent FS for supply. | ||

| 主权项 | 1. A method, comprising: obtaining aqueous samples extracted from a plurality of in situ suction probes positioned at multiple depths within a soil substrate including a root activity zone of an established plant species in the soil substrate; analyzing the aqueous samples to determine a chemical composition of the aqueous samples, the chemical composition comprising concentrations of a plurality of plant nutrients and non-nutrients that act as marker ions; and determining, via at least one computing device, nutrient utilization by the plant species based at least in part upon the concentrations and a distribution of the marker ions with respect to depth of the soil substrate; and determining, via the at least one computing device, amounts of an additive that is added to irrigation water applied to the soil substrate to adjust a chemical composition of the soil substrate to predefined levels, based at least in part upon the determined nutrient utilization and nutritional needs of the plant species. | ||
