A soil apparatus (e.g., seed firmer) having a locking system is described herein. In one embodiment, the soil apparatus includes a lower base portion for engaging in soil of an agricultural field, an upper base portion, and a neck portion having protrusions to insert into the lower base portion of a base and then lock when a region of the upper base portion is inserted into the lower base portion and this region of the upper base portion presses the protrusions to lock the neck portion to the upper base portion.

The present invention discloses a CEEMDAN-based method for screening and monitoring soil moisture stress in farmland, characterised by the steps: preprocessing of remote sensing images, construction of NDVI long time series, CEEMDAN decomposition, calculation of statistical descriptors, screening of soil moisture stress sequences, ground data measurement, construction of soil moisture stress characteristic curves, fitting of soil moisture stress response characteristic curves and predicting the content of soil moisture stress. The invention adopts CEEMDAN decomposition, which solves the problems of noise residue and low reconstruction accuracy in the previous methods, and the high reconstruction accuracy of decomposed component data is more conducive to capturing the transient effects of soil moisture stress, and realizes the screening and extraction of soil moisture stress by combining with the ground measured data. The inverse model of soil moisture content is fitted by combining the effects of multiple indicators, and the CEEMDAN algorithm with remote sensing technology tools to achieve accurate monitoring of soil moisture in a large area of farmland.

A field monitoring and husbandry system is configured for mounting with one or more of an agricultural vehicle or an agricultural implement. The system includes at least one field sensor. The at least one field sensor is configured to measure one or more field characteristics within an agricultural field. The system includes a field husbandry controller in communication with the at least one field sensor. In an example, the field husbandry controller includes a map generation module configured to generate a map of at least the measurements of the at least one field sensor indexed with the one or more associated portions of the field. In another example, the field husbandry controller includes a field characteristic comparator configured to compare the one or more field characteristics with an associated field threshold of one or more field thresholds. The system optionally applies agricultural product(s) based on the comparison.

Multiple subterranean probes at an area of land detect soil conditions and wirelessly transmit soil condition information to a service provider's backend server or to a technician's hand-held wireless device. The server provides multiple user interface screens of a customer application that display soil condition information and irrigation system status. Local micro weather stations may determine and wirelessly transmit weather condition information to the server. An energy emission detecting appliance may be used to acquire information usable to determine fluorescence of grass. The determined fluorescence may be used to train a learning model. The learning trained model may use historical soil condition and fluorescence information to determine a stress level corresponding to the grass. The stress level may be used to modify an irrigation or fertilization schedule.

A soil monitoring system includes a controller having a memory and a processor. The controller is configured to instruct an actuator to drive a shank to move upwardly and downwardly, such that at least one soil monitoring sensor coupled to a lateral side of the shank moves in a cyclical pattern through soil as the shank is driven to move through the soil along a direction of travel. The controller is also configured to receive multiple sensor signals from the at least one soil monitoring sensor while the at least one soil monitoring sensor is at respective depths within the soil, in which each sensor signal is indicative of at least one soil property. In addition, the controller is configured to determine a vertical profile of the at least one soil property based on the sensor signals.

The present invention relates to the technical field of environmental monitoring, and particularly relates to a method for monitoring a forestry microenvironment, comprising the following steps: S1: moving a forestry detection vehicle to a monitoring position; S2: inserting the sampling device on the forestry detection vehicle into the soil at a corresponding depth; S3: disconnecting the sampled soil, and withdrawing the sampling device from the forestry detection vehicle to complete the sampling process; S4: weighing the above soil sample quantitatively, and detecting the soil standard solution through a detection instrument. The sampling device in S1 comprises a rack; an outer sleeve is arranged in the rack; and a sampling mechanism is arranged in the outer sleeve.
