Assessing Livestock Grazing Distribution in Communal Rangelands of the Eastern Cape, South Africa: Towards Monitoring Livestock Movements in Rangelands

Autor: Bukho Gusha, Anthony R. Palmer, Thantaswa C. Zondani

Publikováno v: Land, Vol 12, Iss 4, p 760 (2023)

In the past, rangelands were managed in a semi-nomadic manner, where pastoralists would distribute livestock to different parts of the rangeland depending on the availability of forage. However, understanding how livestock use rangelands has not been

Physical Crust Formation on Sandy Soils and Their Potential to Reduce Dust Emissions from Croplands

Autor: Heleen C. Vos, Wolfgang Fister, Frank D. Eckardt, Anthony R. Palmer, Nikolaus J. Kuhn

Publikováno v: Land, Vol 9, Iss 12, p 503 (2020)

The sandy croplands in the Free State have been identified as one of the main dust sources in South Africa. The aim of this study was to investigate the occurrence and strength of physical soil crusts on cropland soils in the Free State, to identify

Contrasting responses to soil and water salinity in stomata and canopy traits produced convergence of water‐use in tomatoes ( Solanum esculentum ) and okra ( Abelmoschus esculentus ): application to water management

Autor: Jehangir F Punthakey, Anthony R. Palmer, Jamal Kamululdeen, Isa A. M. Yunusa

Publikováno v: Journal of the Science of Food and Agriculture. 102:3227-3236

BACKGROUND Salinity constrains agricultural sustainability and crops differ in their respond. We tested the hypothesis that contrasting responses in canopy and stomatal traits to salinity will cause convergence of water-use for okra and tomato. RESUL

The effects of Acacia mearnsii (black wattle) on soil chemistry and grass biomass production in a South African semi-arid rangeland: implications for rangeland rehabilitation

Autor: Sukhmani K. Mantel, Anthony R. Palmer, Onalenna Gwate, Zahn Munch, Bukho Gusha, Lesley Gibson

Publikováno v: African Journal of Range and Forage Science; Vol. 38 No. 4 (2021); 270-280

Globally, grasslands are under threat from woody encroachment by invasive alien plants and this undermines grass production. The study sought to determine the effects of Acacia mearnsii clearing on soil physico-chemical properties and grass productio

Crust formation on sandy savanna cropland soils and their potential to reduce dust emissions

Autor: Nikolaus J. Kuhn, Wolfgang Fister, Anthony R. Palmer, Frank D. Eckardt, Heleen C. Vos

After the conversion to cropland, dust emissions can lead to the degradation of agricultural soil. There are also offsite effects of dust emission due to the impact of dust on climate, human health, and global biogeochemistry. The sandy croplands in

Assessing the PM10 emission potential of sandy, dryland soils in South Africa using the PI-SWERL

Autor: Frank D. Eckardt, Anthony R. Palmer, Johanna von Holdt, Nikolaus J. Kuhn, Wolfgang Fister, Heleen C. Vos

The Free State has been identified as the region with the most dust sources in South Africa. These dust sources can be linked with the large, heavily cultivated cropland areas in this province, which leaves fields vulnerable to wind erosion after the
