A zeroing adjustment for a depth control system of an agricultural seed planting implement has an adjustable link to compensate for the variable effects of tolerance stack-up and wear, so that all planting units of the implement can be adjusted to a common zero ground penetration setting from which depth settings can be made.

Agricultural devices, row unit adjustment systems, and methods of adjusting a depth of a furrow are provided. In some aspects, an agricultural device is adapted to plant seeds and includes a frame, a furrow opener coupled to the frame and adapted to cut a furrow including a depth, a sensor adapted to sense a characteristic associated with planting seeds and generate a signal associated with the sensed characteristic, and a processing unit receiving the signal associated with the sensed characteristic. The depth of the furrow is adjustable based on the signal associated with the sensed characteristic. Such characteristic may be a characteristic of the soil, a force applied to the agricultural device, or a position of a portion of the agricultural device.

An agricultural system includes a tow bar, a first row-cleaning device, and a second row-cleaning device. The first row-cleaning device is attached to the tow bar via a first frame and includes a first roller device in a trailing position relative to a first furrow-opener disk and configured to crush standing residual plant matter along a first path on a field. The second row-cleaning device is attached to the tow bar via a second frame and includes a second roller device in a trailing position relative to a second furrow-opener disk and configured to crush standing residual plant matter along a second path on the field. The second roller device is offset longitudinally from the first roller device.

An apparatus for forming a water storage material from a biomass input material using supercritical or subcritical fluid processing, the water storage material capable of absorbing a liquid and releasing the liquid. The apparatus utilizes supercritical fluid processing, subcritical fluid processing, charring, or a combination thereof. The apparatus includes a controller configured to control the apparatus. The apparatus further including a processing station configured to hold the biomass input material, and to use the biomass input material for processing into the water storage material.

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.
