Abstract: A yield monitor system is configured to determine how the calibration characteristics of a grain mass flow sensor on an individual combine are affected by grain moisture content and/or other grain parameters which can be measured instantaneously or periodically by the yield monitor system or its operator, or which can be observed by the operator, or which can be determined from other reference information, such as maps of where different grain varieties or hybrids were planted. Other systems, methods, and apparatuses are also provided.

Abstract: A system for monitoring rocks in a field. The system includes at least one row unit having an opening disk, a gauge wheel, and a gauge wheel load sensor. The system further includes a processor and a storage media. In various implementations, the system evaluates gauge wheel load sensor data, vertical acceleration data, and/or down force bore pressure data to detect when a row unit strikes a rock. In some implementations, the system can detect the size of the rock, the location of the rock within the soil, and the severity of a rock strike.

Abstract: The devices, systems, and methods herein use air pressure to dispense seed into the ground in a controlled manner. In certain embodiments, a valve is actuated to push a single seed out of a seed chamber. The seed can be conveyed from the metering housing and through a seed delivery apparatus to the furrow at high speed. The seed is rapidly conveyed from the seed chamber to the furrow by a precisely controlled air pulse to eliminate variation enable high planting speeds.

Abstract: A system for flow control and measurement comprising a fluid tank, a pump in communication with the fluid tank, a manifold in communication with the pump configured to distribute fluid flow to two or more individual lines, and at least one flow device in line with each of the two or more individual lines. The at least one flow device comprising a housing, a hose disposed within the housing, a compression plate configured to compress the hose against the housing, the compression sufficient to close a lumen of the hose when fluid is not flowing through the hose, and at least one sensor configured to determine the position of the compression plate relative to the housing, where the position of the compression plate indicates pressure inside the hose.

Abstract: The disclosed devices, systems and methods relate to agricultural planters, particularly to a two-stage closing system for a planter row unit. In some implementations, the row unit includes a soil engaging member, where the soil engaging member engages at least one sidewall of a trench and displaces soil from the sidewall to cover the seed. In further implementations, the row unit includes a sensing system for sensing sidewall compaction and/or soil moisture.
