Soil Slurry Sampling Workflow for Concurrent Nutrient Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil sampling processes are inefficient as they require drying, grinding, and multiple steps for sample preparation and analysis, which can lead to delays and inaccuracies in determining soil chemical properties.
Innovation Solution
A fully automated computer-controlled sampling system that processes soil samples in the 'as collected' condition, eliminating the need for drying and grinding. The system includes a sample preparation sub-system that mixes soil samples with water to form a slurry and a chemical analysis sub-system that processes the slurry for quantification of chemical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional soil sampling processes are used (drying, grinding, multiple preparation steps), then sample preparation is thorough, but processing time is excessive and efficiency is low
Solution Approach 1:
The invention extracts and eliminates the unnecessary drying and grinding steps from the traditional soil sampling process. By directly mixing fresh soil samples with water to form slurry, the system removes complex preparation steps while maintaining analysis effectiveness, thereby reducing processing time and improving productivity
Solution Approach 2:
The system performs preliminary mixing of soil with water immediately upon sample collection, creating a slurry that is ready for direct analysis. This preliminary action eliminates the need for subsequent drying and grinding steps, streamlining the entire process and significantly reducing processing time
2Productivity
If multiple soil samples are processed sequentially through traditional methods, then each sample receives adequate preparation, but total analysis time increases significantly
Solution Approach 1:
The system enables continuous processing of multiple soil samples by maintaining a constant flow of slurry preparation and analysis. Samples are mixed with water and processed continuously without interruption for drying or grinding, allowing multiple samples to be analyzed in rapid succession, thereby increasing throughput and reducing total processing time
Solution Approach 2:
By performing the mixing action immediately and continuously for each sample as it arrives, the system eliminates waiting time between samples. Each sample is preliminarily prepared in advance (immediately upon receipt) and fed continuously into the analysis system, maximizing throughput and minimizing total processing time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for simultaneous or semi-concurrent analysis of multiple soil samples, significantly reducing processing time and improving the accuracy of chemical property analysis, while maintaining the integrity of the soil samples.
Implementation Method 1
a mixer-filter apparatus which mixes the collected raw soil sample in the 'as sampled' condition (e.g. undried and unground) with water to form a sample slurry
Implementation Method 2
The mixer-filter apparatus then filters the slurry during its extraction from the apparatus
Implementation Method 3
centrifugating the slurry sample to yield a clear supernatant

AI summary
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.
