An automated method includes providing a dry ingredient to be reconstituted into a liquid bioprocess solution and controlling, by a processing circuit, all automated system including at least one mixing chamber, an array of tubing for fluid flow within the system, and a plurality of valves provided within the tubing, to automatically prepare the liquid bioprocess solution from the dry ingredient. Controlling the auto system may include performing a series of sequential mixing steps, the series of sequential mixing steps causing the preparation of the liquid bioprocess solution. The method mixing include taking one or more measurements during the preparation of the liquid bioprocess solution, wherein each step is triggered by at least one of a measurement decreasing below, equaling, or exceeding a measurement threshold. Each step may also include opening or closing, by the processing circuit, at least one of the plurality of valves.

This disclosure features methods of forming chemical compositions. The method includes (1) mixing a plurality of continuous material flows in a mixing tank to form a chemical composition, each continuous material flow including at least one component of the composition; and (2) moving a continuous flow of the chemical composition to a packaging station downstream of the mixing tank. The mixing and moving steps are performed continuously. This disclosure also features systems that can be used to perform such methods.

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 (i.e. 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 sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.
