Grondtipes behoort jou keuse van genetika te beïnvloed
Deur Willem Eigenhuis / Marnus FerreiraHooflandboukundige: Grane / GrondkundigeAgri Technovation Dit is alombekend dat gewasproduksie moontlik direk gekoppel kan word aan grondtipe. Maar wat is die toepassing van grondklassifikasie in die graanbedryf? Genetika (in terme van hibriede) speel natuurlik ook ’n groot rol in die produksie van grane – iets wat elke boer nou al […]

Hoe om jou opbrengs-raaisels te ontsyfer
Deur Carl van HeerdenHoof Landboukundige: GroenteAgri Technovation As die wêreldwye vraag na gewasse so vinnig styg as wat sommige kenners voorspel, sal die oesopbrengs in die volgende paar dekades vinniger moet styg. Beter tegnologieë sal ’n deurslaggewende rol speel om opbrengste te verhoog, terwyl omgewingsimpakte tot die minimum beperk moet word. In die besonder sal presisie-landboutegnologieë ’n […]

The ITEST™ CARBOHYDRATES analysis program – a new tool for citrus growers
By Erik de Vries, Agri Technovation’s Joint CEO Introduction Photosynthesis is a process used by plants to convert light energy (sunlight) into chemical energy that can later be released to fuel the plant’s activities. This chemical energy is stored in carbohydrate molecules such as sugars, which are synthesised from carbon dioxide (CO2) and water (H2O). The […]
