Lead (Pb) and Zinc (Zn) were mined in Kabwe from 1904 to 1994, generating large quantities of solid mine waste. Among the solid wastes, were tailings from the leach plant which are now an environmental concern because of ...

In the light of increasing pressure on limited fresh water resources, the growing world population and increasing greenhouse gas emission, maximizing crop water use becomes an important topic. Considerable research is being ...

Aluminum (Al) toxicity causes high yield losses and is directly linked to acidic soils. Application of lime can ameliorate this problem, but it is costly and not feasible for small scale farmers as they need to purchase ...

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 ...

Generating new information using traditional agricultural trials which are expensive is not sufficient to meeting novel agro-technologies. Planting date (PD), low soil fertility and climate change influences maize (Zea ...

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 ...

Maize is Zambia’s staple food crop, grown by farmers across the country. It is a high nutrient demanding crop that requires adequate amounts of N, P K and other nutrients to obtain economic yields. The recommended basal ...

Agriculture and food security are major themes in Zambia and the world over. The people of Sesheke district have depended on agriculture for many years. This dissertation discusses agricultural change in Sesheke district ...

Development of improved beans varieties that meet consumer choice has been one of the focus areas of many researchers in the Sub-Saharan Africa. In Zambia, various research institutions such as the University of Zambia ...

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 ...
