The main purpose of this research was to systematically review studies on the effects of soil stabilization on the mechanical properties of soil using lime, cement, and fly ash. The systematic review was conducted following the systematic literature review methodology based on the PRISMA guidelines. The review was limited to articles published between 2013 and 2023. From the outcomes of the systematic review, it was found that soil stabilization using either lime, cement or fly ash has significa...

The forms of organic “Po” and inorganic “Pi” phosphorus in the soil, in addition to being influenced by phosphate fertilization, can also be in- fluenced by different soil management systems and cover crops. There- fore, the objective of this work was to evaluate the influence of soil mana- gement systems, cultivated with successions of crops in the forms of “Po” and “Pi”. The experiment consisted of two soil preparation systems (Direct Planting System—SPD and Traditional Planting—PRT) and two c...

The Mount Guera is a particularly fragile environment undergoing soil degradation due to its rugged terrain, the violent nature of the types of precipitations that occur there and its geographical location which places it in the sahelian zone. Also, this environment constitutes the most populated part of the center of Chad, which makes it more vulnerable due to the anthropic action undertaken by men to satisfy their needs. This work aims to assess soil erosion in the region using the RUSLE model...

Sorghum is one of the most important cereal crops well adapted to harsh and dry environmental condition. In Niger, a dry country with limited rainfall distribution (three to four months per year), there are biotic and abiotic factors impacting sorghum cultivation. The objectives of this study were to determine production limiting factors and preferred traits of sorghum farmers in Niger. Twenty sorghum growing villages in Tahoua and Maradi region were surveyed. The villages were selected based on...

The no-tillage system influences the structure of the soil, as the absence of plows combined with the intensive use of heavy machinery contributes to variations in soil density and soil compaction. On the other hand, a no-tillage system tends to increase soil organic matter, which probably increases soil elasticity acting on the soil structure and possibly helping to increase the soil’s mechanical resistance to compaction. In a 2012 study, to evaluate the fit of the resistance curve to soil pene...

In Uganda, sorghum constitutes the second most widely grown cereal according to the latest statistics from the country’s statistics body, the Uganda Bureau of Statistics. This notwithstanding, there has been, in the context of Uganda, very little research and published literature on its potential to sequester carbon. There is no sufficient data on the exact levels of carbon sequestered by this sorghum/legume intercropping system, which is widespread as a technology within Uganda’s smallholder so...

The interaction of organic matter (OM) and clay minerals has been studied as one of the main OM stabilization mechanisms present in different soil classes. The composition of OM present in the soil in terms of humic and fulvic acids and other organic compounds, together with the surface functional groups of different minerals of the clay fraction, such as iron and aluminum oxide and hydroxides type minerals, affect the intensity of the substrate/MO ratio, thus being able to change even the size ...

Radon is the most accessible radioactive gas in life. The radon in ambient air mainly comes from the soil. In order to ensure the accuracy and validity of the measurement of radon concentration in the soil, the paper discusses the influencing factors of the measurement of radon concentration in the soil through the controlled variable method. On the basis of familiarity with the principle of measuring the concentration of radon in the soil, using the radon meter to study the influence of the mea...

Using a portable microcomputer multi-channel gamma spectrometer to directly measure the radioactive content in the soil, the on-site gamma energy spectrum measurement was carried out on the soil of 7 parks in a certain city. The survey results show that the specific activity of 40k in the urban park soil ranges from 470.88 bq/kg to 640.2 bq/kg. The specific activity of 238u ranges from 26.77 bq/kg to 33.31 bq/kg. The specific activity of 232th ranges from 42.14 bq/kg to 54.72 bq/kg. The content ...

This work was carried out in Yucatan Mexico aiming to evaluate the yield performance, Tryptophan (Trp) and Lysine (Lys) contents of two quality protein maize varieties (Sac Beh and Chichen Itza) growing in two Luvisols with low (Lot 1) and high (Lot 2) intensive agricultural use. Six treatments resulted from combining the two varieties with chemical fertilizers (60-80-00):(N-P205-K2O) alone or supplemented with biofertilizers (60-80-00 Mycorrhizae Azospirillum) and the control (00-00-00). Th...
