Agricultural tractor drivers’ health preservation and comfort represent important aspects of the evolution agricultural machinery led to development devices aimed at improving working conditions, such as soundproof cab driver seat suspension, nowadays commonly adopted in tractors. The vibrations are one factors mostly affecting resulting from characteristics interaction specific tractor’s parts...
Following cultivation, substantial loss of soil organic matter occurs in surface layers. No-till is an agronomic practice to reverse or slow the matter. We reviewed 95 research papers that used 13C natural abundance soils quantify impact tillage on C dynamics cropping systems. New (from current systems) accumulated under no-till, whereas most extreme cultivation (mouldboard ploughing) mixed new...
Even when he ploughs such deep furrows as the Schreber case or Freud's own 'Autobiographical Study', he has new lessons to teach us. It is salutary to be reminded, too, that Freud "attributed [Emma Eckstein's] neurosis to masturbation and, following Fliess's 'reflex nasal neurosis' theory, saw the nose as the source of her masturbatory activity". The treatment, as Porter aptly puts it, was "ant...
In this Paper we report on phase resolved I–band optical spectroscopic and photometric observations of Cir X–1 obtained with the Very Large Telescope. The spectra are dominated by Paschen absorption lines at nearly all orbital phases except near phase zero (coinciding with the X–ray dip) when the absorption lines are filled–in by broad Paschen emission lines. The radial velocity curve of the ab...
Abstract Background The role of soil mesofauna in decomposition processes still is debated and this applies particular to arable systems. Aim This study investigates the Collembola crop residues two different tillage Methods We conducted a litterbag experiment long‐term field site Germany managed by conventional (CT; mouldboard ploughing) minimum (MT). Litterbags filled with maize leaf litter m...
Multi‐stakeholder participation for successful implementation of applied research projects in Africa
Rainwater harvesting from Roads For Indigenous Pasture production and improved rural livelihoods in Kitui, Kenya (ROFIP) is an applied research project. It assessed the potential of combining multiple sustainable land management practices, for example native grass reseeding, rainwater roads situ microcatchments to enhance vegetation cover a semi-arid dryland Kenya. Rural earth were used as catc...
The trial was conducted to evaluate the influence of tillage and mulch practices on growth response maize selected forage legumes. With three replications, experiment carried out using a split-plot design. Mulch no were used as major plot treatments straw left from previous cropping season. subplot different namely Minimum (0.2 m) Deep (0.35 m).The research in Foothills Lesotho Ha-Matela Nazare...
The physicochemical and microbial properties of soil under long-term monoculture winter wheat were studied to assess the effects two tillage systems different intensities: reduced (RT) conventional (CT). research was carried out on an 18-year-old experimental field at Grabów (eastern Poland) between 2018 2020. RT (ploughless) CT (mouldboard ploughing) with machine operating depths up 10 25 cm, ...
