A system and method for evaluating soil characteristics. The system and method includes providing one or more soil test kits to a user. The soil tests kits may include ion-exchange resins and may instruct the user to collect a soil sample from his/her growing area, to combine the soil sample with the ion-exchange resins, and to provide the combination to the system for analysis. Other test kits may not include ion-exchange resins and may instruct the user to provide a soil sample from his/her growing area to the system for analysis. The system evaluates the ion-exchange resins and/or the soil samples to identify nutrient levels, pH levels, and other characteristics of the soil. Using the evaluation results, the system provides feedback, recommendations and/or products to the user to improve the soil conditions and to ensure a successful crop, yield, quality, and nutrient density. The system and method also may include providing a second soil test kit to the user at a predetermined time after the first, to evaluate a second soil sample, and to compare the second evaluation results with the first to assess the improvement of the soil conditions.

Systems, methods and apparatus are provided for monitoring soil properties including soil moisture, soil electrical conductivity and soil temperature during an agricultural input application. Embodiments include a soil reflectivity sensor and/or a soil temperature sensor mounted to a seed firmer for measuring moisture and temperature in a planting trench. A thermopile for measuring temperature via infrared radiation is described herein. In one example, the thermopile is disposed in a body and senses infrared radiation through an infrared transparent window. Aspects of any of the disclosed embodiments may be implemented in or communicate with an agricultural intelligence computer system as described herein.

The present disclosure discloses a classification method and system for fine-grained mixed sedimentary rocks, a medium and a terminal. Core description and thin section observation are used to accurately identify the sedimentary structure types and their vertical distribution characteristics from the macroscopic and microscopic perspectives, and indicates the mixed sedimentation characteristics of combination of different lamina or laminar couplets. The micro-drilling sampling technique is used to sample the samples with different types of sedimentary structures while avoiding diagenetic minerals. X-ray diffraction mineral content analysis and a high-precision carbon-sulfur analyzer are used to obtain the contents of different types of minerals and the total organic carbon contents in each sample, respectively, the basic rock type of each sample was determined using a triangular classification diagram. The name of sedimentary structure and the total organic carbon content are added in order before the name of the basic rock type.

A method of indicating a characteristic of a soil sample of a field includes measuring a co-factor in the soil sample and using the co-factor to place the soil sample in a soil sample group. The characteristic of the soil sample is measured and then is scaled based on the soil sample group. The scaled measure is displayed to better represent the characteristic of the soil sample relative to soil samples of the sample group.

An apparatus, system and method for generating crop nutrient prescriptions utilizing a portable soil testing apparatus. The portable soil testing apparatus includes at least one soil sensor for identifying soil properties of plurality of soil samples collected within a field zone associated with a GPS location. A computing device in signal communication with the at least one soil sensor generates the crop nutrient prescription for the field zone based on the identified soil properties of the collected soil samples and may further be based on input of various agronomic factors.
