“…The spraying nozzle installed on the flat cutting knives of the universal deep loosener fertilizer working organ has a semicircular impact surface where the jet is perpendicular on it. The nozzle design and important parameters are given in [21]. The scheme of the presented spray nozzle is shown in Figure 1.…”

“…As an executive part of the agricultural unit, a flat fan nozzle that allows introducing the liquid fertilizers under the soil to the plant roots developing area was designed [19]. The nozzles are designed with low height parameters, because they can negatively influence the draft force of the agricultural unit [19][20][21]. In turn, they must provide the required spraying angle and width of the treated strip.…”

This paper deals with the problem of predetermining the spray angle and uniformity of the flat fan sprayer with a semicircular impact surface for the intra-soil application of liquid mineral fertilizers. The jet impact on a round splash plate and radial atomization properties are investigated theoretically, the formation features of the spray with an obtuse angle are studied in a geometrical way, and the design search of the nozzle shape and optimization calculations are performed using computational fluid dynamics (CFD) simulations and then verified experimentally. It was revealed that the spray rate and spray angle can be adjusted by changing the parameter s, and when the spray angle is within s = 0–0.2 mm, it forms spray angles with range of 140°–175°. The spraying angle, in turn, shows the potential length of the tillage knife in accordance with the undersoil cavity dimensions. A spray uniformity of up to 74% was achieved, which is sufficient for applied studies and for intra-soil application operations. According to the investigations and field experiments, it can be concluded that the designed nozzle is applicable for the intra-soil application of liquid mineral fertilizers. The use of flat fan nozzles that form a spraying band under the soil cavity and along the entire length of the tillage knife ensures a highly efficient mixing process, the liquid mineral fertilizers with treated soil (particles) positively contributing to plant maturation.

“…The review of research works and advanced agricultural practices show that the issues related to mineral fertilizer application by scattering methods have been mainly resolved. However, the mechanical and technological basics of the tiered site-specific intra-soil application of granular and liquid mineral fertilizers have not been developed yet (Tanbayev et al, 2022). Earlier studies (Eskhozhin et al, 2014;Asaf et al, 2007;Alonso-Marroquín and Herrmann, 2005;Aday and Ramadhan, 2019) did not consider issues of interaction of the working tool of the chisel fertilizer with the soil and dependencies connecting its tractive force with design parameters were not defined.…”

An original technical solution is proposed that permits the application of a main fertilizer dose once in 4-5 years at a depth of 6-25 cm with an inclined belt. The work aims to investigate the interaction between the proposed working tool (ripper-distributor) of the developed chiselfertilizer with the soil, and to determine dependences that link its traction force with the design parameters. Studying the soil deformation pattern under the influence of working tool cutting parts based on classical mechanics made it possible to determine the dependence between the tractive force of the ripper-distributor and its design parameters. 3D modeling and C.F.D. analysis by using SolidWorks Flow Simulation ® made it possible to define the fertilizer distributor parameters of the working body and flow characteristics of fertilizers. The distribution quality studies of fertilizer granules in compartments of the working tool distributor showed that the non-uniformity of distribution at different dosages (from 50 to 400 kg/ha) ranges from 7.8% for the application of granulated superphosphate up to 22.7% for the application of powdered superphosphate. The chisel-fertilizer enables soil-friendly and sloping site-specific fertilizer application at a depth from 5. 6-9.8, 16-18, 23-25.8 cm, and a fertilizer distribution non-uniformity of 14-15% over the width of the spreader.

“…The smooth-edge double disc varies depending on different diameters with either matching centers or not [11,12]. Disc colters disturb soil less and require less draft force than hoe openers [13,14]. Therefore, hoe openers are not considered in this research.…”

Double Disc Colter for a Zero-Till Seeder Simultaneously Applying Granular Fertilizers and Wheat Seeds

et al. 2023

The application method of granular fertilizers and wheat seeds depends on the colter design and parameters. In this research, a new double disc colter is studied to apply the wheat seeds to the horizontal band 12 cm in width and apply granular fertilizers deeper 2 cm than the wheat seed level precisely to the middle of the band. Applying granular fertilizers and wheat seeds at different levels increases the granular fertilizer dose without harm to the wheat seeds. Furthermore, applying high doses of wheat seeds to the horizontal band decreases the competition between the seeds and suppresses the weeds. Therefore, preparing a plain seedbed after applying the fertilizers and distributing wheat seeds to the horizontal band was the research objective. The comparison experiments of the base and designed double disc colters were provided in the soil bin determining the horizontal and vertical forces and the placement of the fertilizers and seeds. The discrete element method (DEM) was used to track the soil particle behavior interacting with the double-disc colter. The simulation results and actual experiment results were satisfactory when the AB length of the wing orifice was 60 mm.
