An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the as collected condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (e.g., mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The preparation sub-system may comprise a slurry recirculation flow loop configured with devices to stir, measure, and adjust a water to solids ratio of the slurry.

A liquid circulator for creating liquid circulation in a body of liquid includes a vortex disrupter or blocker that disrupts a vortex created by the circulation assembly of the liquid circulator to minimize or eliminate the slurping/slapping sound. The liquid circulator and vortex disrupter described herein may be used in shallow water with the liquid circulator mounted to a structure, such as a dock or pier. The vortex disruptor permits the circulation assembly to be operated closer to the water surface, while minimizing or eliminating the slurping/slapping sound, and with the circulation assembly further away from the bottom to avoid moving too much debris or possibly causing dredging/trenching on the bottom.

An example fluid moving device for manure agitation in a pit located beneath a confinement building can include: a boom extending vertically into a pump-out wall of the pit; and a mechanism for extending horizontally into a main chamber of the pit to provide agitation. In some examples, the device can also include a self-propelled mechanism for moving along a surface.
