Microbial Community Response to Various Degrees of Pasture Soil Disturbance

Commercial dairy farming from planted pasture is commonly practised in the southern Cape region of South Africa. These pastures are established by various methods ranging in degree of disturbance from no-tillage to conventional tillage. Different establishment methods may alter the below-ground ecosystem, and depending on the degree of disturbance, lead to changes in microbial biodiversity and soil health. Disturbance of pasture soil may play an important role in regulating soil microbial community structure. The aim of this study was to investigate changes in soil microbial community-level physiological profiles of kikuyu (Pennisetum clandestinum) pastures reinforced with annual ryegrass (Lolium multiflorum) by various degrees of soil disturbance

Relational experiences of community members participating in a rural health initiative with interprofessional students

Background. A South African faculty of health sciences created a forum for the community to voice their relational experiences with interprofessional students through visual projections. No other studies that explore such experiences using the Mmogo method could be located. Objective. To gain an understanding of the relational experiences of community members participating in Lifestyle-groups as part of a rural health initiative with interprofessional student groups. Methods. The Mmogo method is a qualitative, structured, observation technique. Participants constructed visual projections representing specific relationships. Thereafter, during a group discussion, participants explained the meaning of their projections. The visual data were analysed according to their literal presentation and subjective, symbolic meaning. A thematic analysis was used for the transcribed data. Results. Thirteen of the 24 visual projections were of a quality that allowed visual analysis; all 24 members participated in the discussions. Light was identified as an overarching theme to represent the community-student interaction. Sub-themes and categories associated with light were healthier lifestyles (knowledge sharing, lifestyle transformation, improved health outcomes), solidarity (reciprocity, collaboration, person centredness, multidimensional approach) and affirmation (gratitude and acceptance). Conclusion. Though some statements by participants related to health education as opposed to health dialogue highlighted areas requiring improvement, the findings correlated with the outcomes prescribed for students by this rural health initiative. Emotional connections in relational experiences could facilitate higher levels of self-efficacy in communities. The question is whether a stronger emphasis on health dialogue can be a catalyst for improved self-efficacy

The Seasonal Nutritional Value of Kikuyu Oversown With Ryegrass and Clover

To overcome the seasonality and relatively low forage quality of kikuyu (Pennisetum clandestinum), annual ryegrass (Lolium multiflorum spp.), perennial white (Trifolium repens) and red clover (Trifolium pratense) can be incorporated into an existing kikuyu stand to improve pasture quality and spring production. The aim of this study was to determine the quality of kikuyu (K), kikuyu oversown with annual ryegrass (KR), kikuyu oversown with a mixture of perennial ryegrass (Lolium perenne) and perennial white and red clover (KRC) and kikuyu oversown with a mixture of white and red clover (KC), in swards grazed by dairy cows

The Seasonal Dry Matter Production and Carrying Capacity of Kikuyu Oversown With Ryegrass and Clover

In the main milk producing areas of the Southern Cape, kikuyu (Pennisetum clandestinum) is considered an important summer and autumn pasture which is climatologically well adapted. The main problem experienced with kikuyu is that winter and spring production is low and the exclusion of legumes make it dependent of nitrogen fertiliser and that increases the input cost. The aim of the study was to quantify the seasonal dry matter (DM) yield and carrying capacity of kikuyu (K) through treatments involving kikuyu oversown with annual ryegrass (Lolium multiflorum spp.) (KR), kikuyu oversown with a mixture of perennial ryegrass (L. perenne) and perennial white (Trifolium repens) and red (Trifolium pratense) clovers (KRC) and kikuyu oversown with a mixture of only perennial white and red clovers (KC)

The Evaluation of Kikuyu Oversown With Ryegrass and Clover in Terms of Milk Production

Kikuyu (Pennisetum clandestinum) comprises the greater part of irrigated summer and autumn pasturage for milk production in the Southern Cape. Milk production per cow is limited by low forage quality. The aim of the study was to determine the milk production from kikuyu (K), kikuyu oversown with annual ryegrass (Lolium multiflorum spp. cv Energa) (KR), kikuyu oversown with a mixture of perennial ryegrass (Lolium perenne cv Yatsyn, Dobson) and perennial white clover (Trifolium repens cv Haifa, Waverley) and red clover (Trifolium pratense cv Kenland, Cherokee) (KRC) and kikuyu oversown with a mixture of perennial white and red clover (KC). The trial was carried out under irrigation using Jersey cows in a put-and-take grazing system. Fertiliser was applied to raise phosphorus level to 35 mg/kg, potash level to 80 mg/kg and the pH (KCl) to 5.5. No nitrogen fertiliser was applied to the KC and KRC pastures

The Seasonal Botanical Composition, Calcium and Phosphorus Content of Kikuyu Oversown With Ryegrass and Clover

Kikuyu (Pennisetum clandestinum) is one of the major grasses used for summer and autumn grazing in the Southern Cape coast area of South Africa. Annual ryegrass (Lolium multiflorum spp.), perennial white (Trifolium repens) and red clover (Trifolium pratense) can be incorporated into an existing kikuyu stand to improve pasture quality and spring production. The aim of this study was to determine the persistence of these species and effects on the calcium and phosphorus content of kikuyu (K), kikuyu oversown with annual ryegrass (KR), kikuyu oversown with a mixture of perennial ryegrass (L. perenne) and perennial white and red clovers (KRC) and kikuyu oversown with a mixture of perennial white and red clovers (KC)
