Method and system for measuring multiple soil properties
First Claim
1. A system for measuring multiple soil properties on-the-go, comprising:
- an implement for traversing a field;
an optical module carried by the implement for collecting soil reflectance data from soil in the field;
a soil EC measurement device carried by the implement for collecting soil EC data from soil in the field;
a soil moisture measurement device carried by the implement for collecting soil moisture data from soil in the field; and
said optical module, said soil EC measurement device and said soil moisture measurement device are arranged to measure soil reflectance, soil EC and soil moisture at approximately the same depth;
wherein said soil EC measurement device and said soil moisture measurement device are arranged to measure soil EC and soil moisture in proximity to said optical module;
wherein said soil EC measurement device and said soil moisture measurement device comprises at least one soil contact member carried by the implement, said at least one soil contact member being arranged for collecting both soil EC data and soil moisture data from soil in the field; and
wherein said optical module comprises a hardened wear plate with a window, and wherein said at least one soil contact member protrudes from or is exposed on a bottom side of said hardened wear plate.

Abstract
A method and system for measuring multiple soil properties on-the-go is provided on an implement for traversing a field. An optical module is carried by the implement for collecting soil reflectance data. A pair of soil contact blades protrude from or are embedded in the optical module for collecting soil EC data and soil moisture data. A switching circuit or phase lock loop allows the same soil contact blades to feed signals to both a soil EC signal conditioning circuit and a soil moisture signal conditioning circuit. The soil moisture data can be used to calibrate the soil EC data and the soil reflectance data to compensate for effects of changing soil moisture conditions across a field. The system can also be used on a planter to control planting depth and/or seeding rate in real time based on multiple soil properties collected during planting.
