PROTEIN RESEARCH FOUNDATION — 2026-07-31Konvensionele bewerking wat op hierdie stadium gedoen word moet grondvog deeglik in berekening neem, aangesien grondvog aanleiding mag gee tot kluitvorming en onegalige bewerking.
- Ploegaksie slegs waar voginhoud van grond reg is;
- Sekondêre bewerking moet tot die minimum beperk word;
- Meganiese beheer van onkruide mag in sommige gevalle gerade wees;
- Verseker dat winteronkruid en opslag van die vorige gewas doeltreffend bestry word.
Bewaringsbewerking is reeds in 'n vorige "flits" bespreek. Maak egter seker dat onkruid doeltreffend bestry word.
- Akkurate tenkmengsels en chemiese middels moet gebruik word;
- Windspoed moet te alle tye in ag geneem word om doeltreffende verspreiding van chemiese middels te verseker;
- Watervolumes moet voldoende wees om onkruide te beheer;
- Groeitoestande van onkruide moet bevorderlik wees vir die opname van gif.
Kalibrasie van planter en spuite
- Alle implemente behoort nou finaal versien te word;
- Kalibrasie van planters en spuite behoort afgehandel te wees;
- Maak seker dat implemente vry van onkruid, stoppels ensovoorts is wat onkruidsaad of siektes kan versprei.
Waar grondverdigting 'n probleem is kan ripaksies uitgevoer word indien dit nie tevore moontlik was nie. Ongeag wanneer gerip word, maak seker dat dit noodsaaklik is.
Saad wat vroegtydig bekom is moet op 'n koel droë plek gestoor word. Sorg dat saad te alle tye baie versigtig hanteer word. Langdurige stoor van saad in 'n warm omgewing wat ook vogtig is, sal kiemkragtigheid en veral groeikragtigheid sterk negatief beïnvloed.

Soil moisture must be taken into consideration if conventional cultivation is done at this stage, as soil moisture may result in clod formation and uneven cultivation:
- Ploughing should be done only if the soil moisture level is correct;
- Secondary cultivation should be limited to minimum levels;
- Mechanical weed control may be advisable;
- Ensure that winter weeds and self-sown seedlings from the previous crop are effectively controlled.
Conservation agriculture was discussed in a previous news flash. Ensure, however, that weeds are controlled effectively:
- Tank mixtures and chemical applications should be accurate;
- Wind speed must be taken into account when spraying to ensure effective application of chemicals;
- Water volumes must be sufficient to control weeds;
- Growing stages of weeds must be favourable for chemical uptake.
Calibration of planters and spraying equipment:
- All implements should be serviced at this stage;
- Calibration of planters and spraying equipment should be completed;
- Ensure that implements are free of weeds and stubble so as to prevent the spreading of weeds and diseases.
If not possible to rip beforehand, ripping can now be done where soil is compacted, but only when this is essential.
Seed should be stored in a cool, dry space, and should be handled with care at all times. Germination and especially growth vigour will be negatively impacted when seed is stored in a warm, moist space.
