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, by a computing device, a composition of a fertilizer solution (FS) that has been supplied to a soil substrate including a root activity zone of a plant species; obtaining, by the computing device, a chemical composition of an aqueous sample obtained within the root activity zone, the chemical composition determined by analysis of the aqueous sample taken from a suction probe positioned within the root activity zone after the FS was supplied to the soil substrate; determining, by the computing device, nutrient utilization by the plant species based at least in part upon the FS composition and the chemical composition of the aqueous sample from the root activity zone; and providing, by the computing device, an amount of additive that is added to irrigation water to produce a subsequent FS that is supplied to the soil substrate.
