The paper presents the results of developing a simulation model designed to calculate the energy performance of the plowing process which enables to perform scenario analysis and identify the optimal combinations of the factors that minimize energy consumption. The developed model serves as the basis for creating a digital twin of the plowing process to significantly reduce the time and cost of the field testing of the new working tool designs and operating modes.
The evolution of physical and technological processes of soil cultivation and the propulsion systems of agricultural machinery for plant-growing have been analyzed in terms of their impact on the development of deflation and erosion-deflation processes across agricultural land types. Based on the analysis of the developed mathematical models and our own research we have developed and patented the method and devices that combine the functions of a propulsion system and an agricultural machine in a single technical system ensuring its integration into natural resource-energy-efficient management without damaging plants or disrupting the soil surface or root-bearing horizons.
The main challenges encountered in developing a digital twin of the working parts of the soil-cultivating equipment were identified. The detailed problem map was compiled where the problems were grouped around three Key modeling areas (production loads, interaction with soil, and calculation of optimal parameters). The solution lies in the field of the process algorithmization and the development of comprehensive domestic software.
The results of exploratory studies on the possibilities of photoluminescent determination of immunoglobulin content in an aqueous solution of the preparation Globcan at a concentration of 0–5% are presented. The excitation spectra were measured using a CM2203 spectrofluorimeter. Integral and statistical parameters were calculated: absorbance, mathematical expectations, variances, skewness, and kurtosis. Upon introduction of the preparation into distilled water, concentration quenching of water luminescence occurs at excitation wavelengths of 214 and 224 nm, while the intrinsic luminescence of Globcan increases upon excitation in the long-wavelength range of 240-320 nm.
The problem of water-borne soil erosion is considered. A set of techniques is proposed to combat it: nonmoldboard, contour tillage, slitting, mulching. Their combination depending on the topography and soil type reduces water runoff and soil loss by up to eight times, increasing moisture retention and crop yields. A rationale for the choice of a combination of tillage techniques that ensure maximum erosion control in the fields with a slope of up to 10 degrees is presented, taking into account the results of geoinformation modeling and the differentiation of technological zones.
