Evidence of Induced Nutrient Deficiency in Pine Plantings on Previously Cropped Lands
Item type: Journal Article • Journal: South African Forestry Journal • Authors: A.W. Schumann --- , South Africa A.D. Noble --- , South AfricaWidespread establishment failures of Pinus species have recently occurred on agricultural land acquired for commercial forestry in South Africa. These include about 10 000 ha of previously tilled soils in the north-eastern Cape belonging to Mondi Forests. A lettuce (Lactuca... -
Are soil-borne diseases depressing yields of continuously-grown maize in Natal?
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: P. Channon --- , Republic of South Africa M. P.W. Farina --- , Republic of South AfricaLong-term field trials suggest that yields are declining where maize (Zea mays L.) is grown continuously in some parts of Natal. Available evidence indicates that the decline is not ascribable to soil fertility or climatic constraints and the possibility exists... -
Pentachlorophenol-contaminated soil bioremediation: survival and efficacy of monoculture inoculants and enrichment of indigenous catabolic populations
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A. D.K. McBain --- Department of Bioscience and Biotechnology, United Kingdom M.S. Salkinoja-Salonen --- Department of Applied Chemistry and Microbiology, Finland E. Senior --- , South Africa C.A. du Plessis --- Department of Microbiology and Biochemistry, South Africa A. Paterson --- Department of Bioscience and Biotechnology, United Kingdom I.A. Watson-Craik --- Department of Bioscience and Biotechnology, United KingdomSurvival and efficacy of monoculture inoculants of Flavobaderium sp. and Rhodococcus chlorophenolicus to bioremediate PCP-contaminated soil were examined under sterile and non-sterile conditions. Both species effected ≥ 40% catabolism in four weeks although inoculant survival was significantly higher with R... -
Effect of crop rotation on the severity of grey leaf spot on maize
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: E. Smit --- , Republic of South Africa B.C. Flett --- , Republic of South AfricaGrey leaf spot (GLS) caused by Cercospora zeae-maydis Tehon and Daniels has become the most important foliar disease of maize in South Africa. Crop rotation has been applied successfully to control or reduce the incidence and severity of plant diseases... -
Crop rotation in the summer rainfall area of South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A.A. Nel --- ,Crop rotation is the successive growing of different crop species on fields with the aim to assist sustainability. Monoculture cropping, the opposite of crop rotation, of maize was and still is the main practice in the summer rainfall area of... -
Financial Profitability of Carbon Offset Monoculture Plantation Forestry on Smallholder Farms in Trans Mara Sub-County, Kenya
Item type: Journal Article • Journal: East African Agricultural and Forestry Journal • Authors: J. Chemuliti --- Kenya Agricultural and Livestock Research Organization, Kenya C. Ackello-Ogutu --- Department of Agricultural Economics, Kenya S. Mbogoh --- Department of Agricultural Economics, Kenya P. Irungu --- Department of Agricultural Economics, KenyaThere is growing interest in the development of smallholder carbon offset forestry projects in Africa as a means of mitigating climate change while providing co-benefits of development and environmental protection and conservation. Financial profitability of carbon projects is a key... -
High sorgoleone autotoxicity in sorghum (Sorghum bicolor (L.) Moench) varieties that produce high sorgoleone content
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: H Tibugari --- , South Africa C Chiduza --- , South Africa AB Mashingaidze --- , Zimbabwe S Mabasa --- , ZimbabweSorghum autotoxicity can inhibit germination and growth, resulting in low plant densities and reduced crop productivity. Three sorghum varieties (Dhlakama, Shirikure and Macia) were evaluated for autotoxicity in 2018 at the University of Zimbabwe. Experiments were set up for 3... -
Weed species diversity and shifts in Conservation Agriculture-based crop rotation systems on the Highveld area of South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Elbé Hugo --- , South Africa Maryke Craven --- , South Africa Andries A Nel --- , South AfricaThe occurrence and infestation levels of weed species are known to vary greatly within Conservation Agriculture (CA) systems as weed species will react differently to different habitats. Two on-farm CA trial sites, near Buffelsvallei and Viljoenskroon respectively, were established during... -
Chameleons and vineyards in the Western Cape of South Africa: Is automated grape harvesting a threat to the Cape Dwarf Chameleon (Bradypodion pumilum)?
Item type: Journal Article • Journal: The Journal of the Herpetological Association of Africa • Authors: KrystalA. Tolley --- South African National Biodiversity Institute, South Africa G. John Measey --- University of the Western Cape, South AfricaThe use of automated grape harvesters in the Cape Wine Growing region has resulted in controversy regarding their effect on the chameleon Bradypodion pumilum. We investigated densities of B. pumilum during harvesting at a vineyard near Stellenbosch, South Africa. During...
