[Problem] To provide: a core barrel head capable of definitely recovering an inner tube in which a geological sample has been collected in a situation where excavation is performed in a horizontal direction and in a rising gradient direction; an inner tube assembly provided with said core barrel head; and an inner tube recovery method.

[Solution] The present invention has: a main shaft 31 connected to the rear end of an inner tube 2; an inner fixing latch 32 that is axially supported at a substantially intermediate position along an axial direction of the main shaft 31; a latch disengagement slide tube 33 that is mounted to the outer circumferential surface of the main shaft 31 slidably in the axial direction and that disengages the inner fixing latch 32 from a locking groove 43 by inclining the inner fixing latch 32 against a biasing force; and a slide tube fixing latch 34 that locks the latch disengagement slide tube 33 at a position where the inner fixing latch 31 is in an expansion state and that disengages the lock of the latch disengagement slide tube 33 by being inclined by an overshot.

Disclosed herein are a system and method that integrate vineyard sensor data into an environment that enables analysis, historical trend analytics, spatio-temporal analytics, and weather model fusion for improved decision making from vineyard management to wine production. The integration of new sensor data from multiple soil depths with surface measurements, combined with production flow process and historical information enables new decision making capabilities. A wireless network of sensor/transmitters can be distributed to provide a 3-dimensional assessment of water movement both across the grower's field and as it moves from the surface through the root zone. The soil monitoring data stream feeds into a visualization interface that will be incorporated in software based decision aid and crop management tool that helps agricultural producers reduce costs, minimize water and nutrient applications, and better protect the environment by reducing agricultural production inputs.

A soil analysis device is configured to create a soil sample solution. The device includes a reservoir configured to store an extractant, a mixing chamber coupled to the reservoir and configured to receive extractant from the reservoir and to receive a raw soil sample, and a control system. The control system is configured to determine an amount of extractant needed to produce, from the raw soil sample, a soil sample solution with a particular soil-to-extractant ratio and configured to cause the determined amount of extractant to be transferred from the reservoir to the mixing chamber.

The present invention is an apparatus which executes a photogrammetry method for calculating soil density. After a user excavates soil, measures the mass of the excavated soil and takes multiple images of the excavation site in combination with a calibration object, a data processor uses the various values obtained from the collected images to create a point cloud data object. The processor used this point cloud data object to create a visual representation of the hole. The processor rotates and scales the visual representation. The processor also uses the point cloud data object in volumetric calculations to determine the volume of the hole. Together with the soil mass, the volume allows calculation of soil density.

A method, system and computer program product for determining soil properties comprising a probe including at least a liquid injection port and a pressure transducer. The probe is pushed into a soil and one or more pumping tests are carried out, wherein during a pumping test infiltration liquid is pumped through the liquid injection port of the probe. By means of the pressure transducer a pressure response in the soil resulting from the injection of liquid through the liquid injection port is measured for each of the one or more pumping tests.
