Field Trip: CEDARA Research Farm

  1. 1. CEDARA RESEARCH FARM FEEDBACK FROM FIELD VISIT Rapporteurs: Divine Ntiokam & Cyril Ceshe Presented at the 3rd Agricultural Extension Week, 30 October – 3 November 2017
  2. 2. Overview • Number of delegates visiting: 86 • Sub-sector: Department of Agriculture & Rural Development – Soil Science • Host names: i. Guy Thibaud (Soil Scientist) – presentation on no-till research in KwaZulu-Natal ii. Dr Manson (Soil Scientist) & Allister – field demonstration • Key project/program: Conservation Agriculture (CA) • Stakeholders: Researchers & Extension Officers
  3. 3. Overview Three main principles of CA: • Minimum soil disturbance • Permanent soil cover: crop residue /live mulch • Crop rotation and /or intercropping Three pillars of CSA: • Sustainable increases productivity & income • Strengthens resilience to CC & variability • Reduces agriculture’s contribution to CC
  4. 4. Project/program Cover crop / live mulch: • Vetch cover crop with zero N ( maize green & healthy because vetch fixes N ) • No cover crop with zero N ( maize yellow, stunted because absence of N) • Benefit – buy less Nitrogen fertilizer Intercropping: • Small-scale farmers – plant maize & leave rows of 1,5 – 2m in between maize crop • Once the maize has grown, spray cover crops & plant dry beans • Cover crops prevent erosion, soil is always moist, produces higher yields compared to planting maize & beans separately
  5. 5. Summary presentation of CA ( No-Till)
  6. 6. Assimilation of rainfall on a ploughed and mulch interfaces Ploughed area looses all nutrients; the mulched area has a good water retention as well as nutrients
  7. 7. Demonstration of planting using No-till planter View after planting and spraying herbicides
  8. 8. Demonstration of No-Till maize planters
  9. 9. Lessons learnt • CA improves agricultural production and productivity • Reduces labour and increases profit • Increases resilience to dry and hot spells by avoiding soil water storage • Reduces soil erosion • Improves soil structure • Increases soil organic matter content thus increasing soil carbon sequestration
