Comparative analysis of heavy metal concentration in secondary treated wastewater irrigated soils cultivated by different crops
(Springer, http://link.springer.com/, 2010-03)
The use of treated urban wastewater for irrigation is a relatively recent innovation in Botswana and
knowledge is still limited on its impact on soil heavy metal levels. The aim of this study is to analyze and compare ...
Pollution implications of Save River water from weathering and dissolution of metal hosting minerals at Dorowa phosphate mine, Zimbabwe
(Elsevier Science Ltd, http://www.elsevier.com/locate/pce, 2010)
The study set out to determine the weathering and dissolution of metal hosting minerals at Dorowa for purposes of deducing pollution potential to the nearby Save River. Phosphate rock is mined at Dorowa for
the production ...
Natural attenuation of mining pollutants in the transboundary Save River
(Elsevier Science Ltd, http://www.elsevier.com/locate/pce, 2011)
The objective of the study was to investigate the role played by the natural environment in protecting the
transboundary Save River from the impacts of metals derived from phosphate mining at Dorowa. The
study is a follow ...
Minerals that host metals at Dorowa Rock Phosphate Mine, Zimbabwe
(Bentham Open, http://www.benthamscience.com/open/tomj/index.htm, 2011)
This study set out to establish the major minerals at Dorowa and determine which of those are likely to host metals that may leach into surface and groundwater. This study comes after a preliminary assessment of the water ...
Analysis of the effects of kraal manure accumulation on soil nutrient status through time
(Academic Journals, 2010-11)
This study investigated the influence of the accumulation of animal wastes on the soils of active kraal sites through time. This investigation involved the sampling and analysis of the soils of kraals that had been in use ...
Chicken manure-enhanced soil fertility and productivity: effects of application rates
(Academic Journals, http://www.academicjournals.org/JSSEM, 2010-05)
The utilization of chicken manure as an organic fertilizer is essential in improving soil productivity and
crop production. We carried out the study to assess the effects of chicken manure on soil chemical
properties and ...
Making markets work for the poor (M4P) approach and smallholder irrigation farming
(Omics Publishing Group; www.omicsgroup.org, 2015)
The aim of this article is to show what M4P is, how it came into being and how it has been used to guide
intervention in different context and to weigh the extent to which it can be used to guide the study and interventions ...
Seasonal diet preference of cattle, sheep and goats grazing on the communal grazing rangeland in the Central District of Botswana
(Academic Journals; http://www.academicjournals.org/AJAR, 2015-07-16)
Diet composition, forage preference and diet overlap among of goats, sheep and cattle grazing on communal rangeland in the Central District of Botswana were evaluated to determine the potential for forage competition to ...
Analysis of persistence soil nutrient statusin abandoned cattle kraals in a semi arid area of Botswana
(Academic Journals, http://www.academicjournals.org, 2011-12-04)
The aim of this study was to analyze the depletion of soil nutrients with time on abandoned kraals in a peri-urban area of Botswana. Active kraals are enriched with nutrients through the accumulation of animal droppings ...
Comparative effects of secondary treated waste water irrigation on soil quality parameters under different crop types
(Global Science Books, http://www.globalsciencebooks.info/Journals/AJPSB.html, 2011)
This study compares soil quality parameters, and salinity and heavy metal levels in soils cultivated with different crops under secondary treated wastewater irrigation in the Glen Valley, near Gaborone City, Botswana. The ...
