Tillage intensity may differently impact gaseous losses of C and N to the atmosphere, but data from long-term experiments are relatively few. Yet, this information is needed better understand gains in agricultural systems. The objective study was determine how tillage affects soil greenhouse gas (GHG) fluxes (CO 2 , O, CH 4 ) by comparing experimental moldboard plow (MP), chisel (CP), double di...

To develop sustainable cropping systems, the coherence between economic, environmental, and energy aspects must be considered. We aimed to assess sustainability of corn (Zea mays) production using four tillage systems which varied in intensity soil disturbance (i.e., conventional till with moldboard plow (MP), chisel (CP), strip-tillage (ST), no-till (NT)) by performing life cycle assessment (L...

Energy consumption in Iran is a subject of debate. Some may think that oil is cheap in Iran and thus no need for this kind of research. This simple minding is erroneous first because Iran subsidizes billion dollars each year for the imported diesel fuel specially for agricultural use and second because energy studies reveal the degree of professionally using the technology. We can easily find t...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

Soil organic matter (SOM) is a complex mixture of multiple fractions soil C (SOC) that can be influenced by management decisions. This study evaluate the effects tillage (moldboard plow [MP] and no-tillage [NT]) commercial fertilizer as limestone ammonium nitrate (28–0–0) at three rates (0 [0-N], 100 [100-N], 200 [200-N] kg N ha–1) on SOC, total (STN), SOM (total particulate matter-C [POM-C] mi...

BACKGROUND The temporal sensitivity of the surveillance system (TemSSe) for Bovine Viral Diarrhea (BVD) in Danish dairy herds was evaluated. Currently, the Danish antibody blocking ELISA is used to test quarterly bulk tank milk (BTM). To optimize the surveillance system as an early warning system, we considered the possibility of using the SVANOVIR ELISA, as this test has been shown to detect B...

The study aims to substantiate the design scheme of a linear plow with disk angle. authors have developed for smooth, furrowless plowing. proposed has disc lugs, screw housings, and guide plates. technological turnover polygonal layers formed by pre-plates, mutual arrangement housings plates, general view laboratory-field installation conducting experiments are given. During experiments, degree...

The article presents the effect of using a tillage tool with skimmers, second stage and bodies (double-deck plow) on reduction traction resistance energy consumption by at least 1.1 kN, i.e., 3.3%. In addition, statistical characteristics plowing depth width longitudinal profile field are stabilized. use agricultural machinery secondary or ensures even distribution fluctuations. plow without sk...

Purpose: to study the deflation manifestation patterns on Rostov region soils in cold and warm periods of year, depending agricultural background, projective cover soil surface by plants availability reclamation protective forest plantations. Materials methods. Deflation studies were being carried out Aksai Orlovsky districts from 1970 2022. Conventional research methods including measurement w...
