In Zambia, most crops are mainly produced by small scale resource poor farmers who rely on soils with inherently low fertility. When soil productivity declines farmers put affected fields on fallow to allow the fertility to regenerate, and open up new fields. This type of farming is not...

Biochar is an organic residue combusted under low oxygen conditions, resulting in a porous, low-density carbon-rich material. Biochar has the potential to reduce pollutant mobility when used as an organic soil amendment. Until recently, Biochars’ potential has not been extensively evaluated for...

Past and present-day erosion is a significant form of land degradation that has rendered vast areas of sloping land unproductive with respect to crop production. Thus, conservation tillage, along with complementary practices such as soil cover and crop diversity has become a better option to...

Organic amendments have been known to improve soil physical and chemical properties in sub-Saharan Africa. However, research information on how organic amendments affect aggregate stability and the degree of their effects in comparison to others is indaquate in Zambia. The study was therefore...

In machining operations, the effects of high temperatures are i) reduction in tool life, ii) production of hot chips and iii) inaccuracies in workpiece dimensions. Coolant is applied to convey away heat to extend tool life and ensure a good surface finish of the workpiece. While conventional...

Agricultural practices that conserve soil moisture are inevitable in the face of erratic rains and constant droughts. Mulching can improve water productivity through increase in water retention and reduction in surface evaporation. The study was conducted in Lundazi District of Eastern Province...

Soil acidity is a common constraint to crop production in Zambia. Agricultural lime is applied in dry powder form to acid soils to neutralize acidity. New liming materials in aqueous suspension form have recently been introduced on the Zambian market and their effectiveness in neutralizing...

Technology ranges from the basic notion of tools, to systems which employ or exploit it. Some common examples of technology include videos, simulations, virtual and remote laboratories, games and tablet computing. Though some of these can be useful in the learning of O-level biology topics that...

In general, a healthy marriage setting is perceived as one in which a couple lives together in order to shape the value system of a family. Recently, many couples do not live together, but in a distant town or city, and are called commuter marriage or distance marriage. The aim of this study was...

Aristolochia species grow in different parts of Zambia and are used globally for medicinal purposes. Many Aristolochia species have been associated with adverse effects including renal and hepatic dysfunction. This study investigated the effects of hydro-alcoholic seed extract of Aristolochia...
