A mathematical model for fall armyworm management on maize biomass
(SpringerLink, 2012)
Fall armyworm (Spodoptera frugiperda), a highly destructive and fast spreading agricultural pest native to North and South America, poses a real threat to global food security. In this paper, to explore the dynamics and ...
Drought and grazing influence on Northern Chihuahuan desert rangelands, New Mexico.
(Botswana University of Agriculture and Natural resources, 2013)
A short term cattle grazing trial was started in June 1992 in the Chihuahuan Desert in Southern New Mexico to study the influence of drought and grazing on plant responses. Paddocks were grazed in June and September each ...
Deposition rates of atmospheric particulates determined from 210Pb measurements in soils and air
(HARD Publishing, 2010)
Deposition rates of atmospheric particles were determined using previously published
210Pb data in soils and air. The dry deposition velocities for moorland and woodland soils
were 2.2±1.8 and 9±2 mm• s-1, respectively. ...
The effect of purified condensed tannins of forage plants from Botswana on the free-living stages of gastrointestinal nematode parasites of livestock.
(Elsevier, 2013-10-18)
The effect of condensed tannins (CT) extracted from forage plants from Botswana on the free-living stages of a number of species of gastrointestinal nematode parasites derived from infected sheep were investigated using ...
Assessment of γ-radiation levels and associated dose rates from surface soils in the eastern part of Botswana
(INDERSCIENCE Publishers, 2014)
This paper reports the γ-radiation levels of the naturally occurring 40K, 210Pb, 232Th and 226Ra and the anthropogenic 137Cs in the eastern part of Botswana so as to assess their possible dose impact to the members of the ...
