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...

The data on receipt of photo synthetically active radiation (FAR) on the soil surface and the coefficient of its use over the years and periods of the year de-pending on the hydrothermal conditions and dynamics of harmful salts in the soil are given. The items of the changes in the species composition of phytoce-noses depending on the environmental factors are considered.

Depletion of soil fertility is a main problem to sustain agricultural production and productivity in many countries. The use of inorganic or organic fertilizer alone has both positive and negative effects on plant growth, nutrient availa-bility and the soil. Organic fertilizer improves physical and biological activities of soil but they have comparatively low in nutrient content, so larger quantity is required for plant growth. Ho

Rural communities in
sub-Saharan Africa develop different livelihood strategies driven by
opportunities and constraints encountered in existing biophysical and
socioeconomic environments. A study on gender effects under two market linkages
on investments in soil conservation innovations in potato production systems
was conducted in the highlands of southwestern Uganda. There were significant
differences in lan
