Inventions include methods and systems for evaluation of agriculture sites and execution of actions for improving various site parameters in a sustainable manner. In embodiments, a method for characterization and improvement of an agricultural site includes: receiving a set of agriculture samples from an agriculture site or in association with an agricultural process; generating sample data upon processing the set of samples with a set of sample processing operations; generating a set of features upon performing a set of transformation operations upon the set of data streams; returning an analysis characterizing a status of the agriculture site in relation to at least one perturbation, upon processing the set of features; and executing an action for at least one of maintaining and improving the agriculture site, based upon the analysis. The inventions implement features associated with composition, network properties, and emergent properties as biomarkers for characterizing statuses of sites under analysis.

The present disclosure provides an isolation and restoration method for compound contaminated soil. The isolation and restoration method for the compound contaminated soil provided by the present disclosure is used for isolation and restoration of a contaminated site, which includes: laying an isolation layer, a pure soil layer and an arable soil layer containing compound soil in turn on the contaminated site which is flattened and compacted, where the compound soil is composed of loess, slaked lime, fine sand and substances having an adsorption function in a volume ratio.

A coastal severe saline-alkali soil improvement and vegetation construction system consists of four parts of content, respectively a soil improvement part, a saline-alkaline tolerant plant resource utilization and planting technology part, an irrigation and drainage mating system part, and a part for managing saline-alkaline soil improvement and operation by adopting an automated information technology. A whole set of complete operation system is formed for performing improvement and vegetation construction on saline-alkaline soil from the four parts, thereby providing a feasible high-efficiency method for saline-alkaline soil improvement of a coastal region.

Disclosed is an assembly for mitigating soil compacted by wheels or belts of a vehicle moving over soil and carried by the vehicle. The assembly operates with a series of blades affixed to a rotatable shaft and displaying an elliptical pattern. A hood confines about the top half of the blades and spans about the width of the assembly. A motor rotates the rotatable shaft. A mounting assembly mounts the assembly to the vehicle behind and in alignment with the vehicle wheels or belts. A cylinder assembly reversibly moves the assembly from a home position downwardly into compacted soil for its mitigation.

An autonomous soil sampling device. The device including a vehicle for generally autonomously navigating a given area for sampling and adapted with systems to generally avoid obstacles during maneuvering. The device including a soil sampling system designed for placement on a platform of the vehicle and including an extraction arm having a probe and auger to probe into the soil for extracting a quantity of soil. The extraction arm rotationally received on a housing and movable to an inverted position for depositing the quantity of extracted soil into a packaging assembly for collection, labeling, and storage of the individual samples.

The present disclosure relates to a pneumatic serial device for spraying materials into a deep soil layer and an implementation method thereof. The device comprises a material spraying injector (1), a air blasting system (2) connected with the material spraying injector (1), and a material feeding system (3), wherein the air blasting system (2) and the material feeding system (3) are connected with the material spraying injector (1) in series in sequence, wherein the air blasting system (2) comprises a high-pressure air tank (2-1) and a quick relieve valve (2-2), the material feeding system (3) comprises a material chamber (3-1), a feeding valve (3-2), a valve I (3-3), a material sending chamber (3-4), a valve II (3-5) and a material delivery pipe (3-6) which are connected to each other in sequence, and the material delivery pipe (3-6) extends into the high-pressure air tank (2-1) and is communicated with the quick relieve valve (2-2) at the bottom thereof. Combined with the implementation method thereof, the device can uniformly apply a certain amount of various materials into the soil layer at any depth, replacing the traditional method, greatly improving the operation efficiency of applying materials into the deep soil layer, significantly reducing the cost of applying materials into the deep soil layer, and reducing the labor intensity.

The disclosure provides a structure for treating saline alkali soil and a biological treatment method, relating to the technical field of bioremediation for special soil and solving problems of single existing saline alkali soil improvement method, long improvement period, high cost and poor effect due to a single material. In the disclosure, a collecting layer, impermeable layers, and a plough layer are paved upward from a saline alkali soil layer in sequence. The impermeable layers and the collecting layer are made with a biological material, and the plough layer is improved, which reduces the content of harmful salt in the plough layer and improves the water holding capacity and permeability of soil in the plough layer. A collecting pipe network is buried under the plough layer, and collection pools are arranged at points of the pipe network for salt collection, permanently removing harmful salt components in the saline alkali soil.
