Increasing agricultural production is an important food task. In providing plants with the necessary nutrients, it is necessary to intensify by applying fertilizers or using alternative environmentally friendly methods. These include technologies that allow the conversion of nutrients into a form accessible to plants, and electrophysical technologies using high-voltage pulse discharge. This article describes the installation for creating electrohydraulic shocks. The experimental studies on the justification of the parameters of electro-hydraulic treatment of solutions and the study of the effect of treatment by solutions treated with electro-hydraulic shock on the development of crops using the example of tomato resulted in obtaining the optimal process technological parameters of the installation. They are voltage – 30 kV, discharge capacitance of the capacitor – 0.6 μF, number of pulses – 200.
When evaluating tillage machines, one of the important places is occupied by agrotechnical assessment of the quality of the technological process of tillage. The properties of the soil as an object of cultivation, as well as the processes occurring during the interaction of the soil with any materials, are studied by agricultural mechanics, created by V.P. Goryachkin. One of the most important characteristics of the soil condition is the hardness of the soil, or the resistance provided by the soil to the penetration of any deformer into it. This article describes the forces and stresses that occur when the plunger penetrates into the soil. According to the theoretical provisions, friction force F, drag force Q, total force P, stresses σ1 and hardness T are calculated, theoretical dependences of soil hardness on the tip diameter on compacted and loose soil are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
