“…The systemic approach for protecting soils against erosion implies the development and implementation of a complete package of erosion control measures, designed on the basis of the actual landscape and including the arrangement of agronomic, forest management and hydraulic engineering measures. In recent years, a number of methodological studies were published [Kashtanov et al, 1997;Morgan, 2005;Glinski et Volnov and Boiko, 2015;Chalov, 2016;Stepanjevic, 2021], outlining the new methodical principles for the research into soil-erosion processes in agricultural landscapes and their environmental consequences, the development of the optimal system of measures for preventing the degradation of the soil cover and the contamination and silting of minor rivers as well as improving the productivity of cultivated lands. The new approach implies, first of all, research into the moisture rotation processes: precipitation, the variation of the land moisture content and water permeability, the overland slope runoff.…”

The erosion of soil falls into the class of landscape destruction processes. It disturbs the balance in the geoecosystem to a significant extent, thus generating the whole spectrum of negative geo-ecological after-effects. The protection of soils against erosion and the improvement of fertility in sloped agricultural landscapes are part of the overall environmental concern that has notably aggravated lately. This has given rise to a number of topical issues for which scientific and practical solutions are urgently required. The paper describes the state of the art in the research into the issue of the protection of soils against erosion. It discusses the regional patterns in the progress of erosion processes. The integrated agro-ecological assessment of the effect that various components of the integrated erosion protection system have on the erosion resistance and properties of soils in agricultural landscapes was outlined for the development and implementation of conservation cropping systems. The study is based on the results of the long-term stationary and expeditionary field research that addressed the following issues: the natural conditions of the territory and the development of erosion processes as a result of snowmelt and rain water runoff, as well as artificial sprinkling. The research was carried out using a combination of geomorphological, cartographic and pedomorphological analysis methods and approaches. By modelling rainfalls on typical eroded chernozem soils in combination with different agricultural crop growing technologies, the quantitative characteristics for the resulting erosion losses were determined. These characteristics are needed to make long-term forecasts of the development of erosion processes in agricultural land areas in the context of intensifying exogenic processes. The tested soil-protecting agronomic technologies (subsurface blade tillage to a depth of 10-12 cm with simultaneous slitting to a depth of 40 cm, subsurface blade tillage to a depth of 20-22 cm) demonstrated their high erosion prevention efficiency. They reduced the surface run-off by a factor of 1.3-2.3, the soil loss by a factor of 1.9-12.7 in comparison to the traditional ploughing to a depth of 20-22 cm. Accordingly, the indices and conditions of the surface run-off water infiltration into the soil were also optimised with these techniques.

“…The application of the knowledge of physics in the agriculture domain has contributed to the shift from a mere subsistent farming system to a highly mechanized farming system which in turn enhanced sufficiency in the food supply in most countries of the world. According to Gliński et al [3], physics plays very part in the restriction of threats to agricultural resources (agricultural products, soils, foods and plants) and, the environment.…”

Effects of hands-on instructional strategy on senior school students’ performance in waves

The research examined the effects of hands-on teaching strategy on senior school learners’ performance waves in Ilorin, Nigeria. Senior secondary school (SSS2) science students were sampled at intact classes using a purposive sampling technique. Researcher-designed instructional packages on waves and Physics achievement test on waves (PATW) were the instruments employed. The gathered data were analysed with the use of descriptive and inferential statistics. Percentage, mean and standard deviation were employed in answering the research question. Meanwhile, Analysis of Variance (ANOVA) was utilised in testing the hypotheses formulated at a 0.05 alpha level. The study showed that students’ performance exposed to hands-on instructional strategy was very impressive, while students’ performance exposed to traditional strategy was low, there was a significant effect of hands-on instructional technique on the performance of students in waves and no statistically significant collaborative effect of hands-on instructional technique and students’ gender on performance in waves. It was suggested that hands-on instructional strategies should be integrated and used to make teaching and learning more concrete and active based for both teachers and students.

“…Soil, being the top layer of the Earth's crust and a component of many ecosystems, undergoes continuous degradation [ 1 , 2 ]. One of the forms of this degradation is water erosion [ 3 – 5 ], the first step of which is the splash phenomenon.…”

Effect of Soil Moisture Content on the Splash Phenomenon Reproducibility

One of the methods for testing splash (the first phase of water erosion) may be an analysis of photos taken using so-called high-speed cameras. The aim of this study was to determine the reproducibility of measurements using a single drop splash of simulated precipitation. The height from which the drops fell resulted in a splash of 1.5 m. Tests were carried out using two types of soil: Eutric Cambisol (loamy silt) and Orthic Luvisol (sandy loam); three initial pressure heads were applied equal to 16 kPa, 3.1 kPa, and 0.1 kPa. Images for one, five, and 10 drops were recorded at a rate of 2000 frames per second. It was found that (i) the dispersion of soil caused by the striking of the 1st drop was significantly different from the splash impact caused by subsequent drops; (ii) with every drop, the splash phenomenon proceeded more reproducibly, that is, the number of particles of soil and/or water that splashed were increasingly close to each other; (iii) the number of particles that were detached during the splash were strongly correlated with its surface area; and (iv) the higher the water film was on the surface the smaller the width of the crown was.
