The use of NutriCAST™ in row crops
Dr. Teunis Vahrmeijer, Director Business Development, Victus BioDr. Stefan van Wyk, Head of Biological Research and Product Development, Victus Bio NutriCAST™ for healthy soilsFrom the very birth of the concept Soil Health in 1909(1), it was recognised that soil fertility not only refers to the nutrient status of soils, but also includes the carbon content […]
Survival to symbiosis: Improved soybean nodulation in adverse in-field conditions
Claire Randolph (MSc), Victus Bio, Co-author: Dr Stefan van Wyk, Victus Bio Soybeans and the underground partnerSouth Africa’s soybean sector is evolving into a key player in agriculture, with more producers recognising the crop’s value in crop rotations, soil health improvement and profitability. But successful soybean production does not only rely on good seed, timely […]
Stronger by nature: Calcium and silicon technologies
Rochelle Thuynsma, Head of Field Products: Technical Calcium and silica are fundamental elements in plant and soil systems, each contributing uniquely to cell wall stability, stress mitigation and nutrient dynamics, making their combined role increasingly relevant in the development of sustainable agricultural practices. CALCINATOR™CALCINATOR™ is a pectin complexed foliar calcium (Ca) source formulated to enhance […]
Benefits of SF-RTK boundaries in broadacre farming
Gerald Smith, Head of Field Operations IntroductionPrecision agriculture has revolutionised broadacre farming, enabling producers to optimise crop yields, reduce waste and promote sustainability. One crucial aspect of precision agriculture is the use of Sub-Foot Real-Time Kinematic (SF-RTK) boundaries for variable rate applications. Previous non-precision methods applied to determine block, field and zone boundaries on large […]
Invoortoedienings en waterstres: Sukses in die Swartland
Nicola Kotzé, Senior Agronoom Schalk du Plessis, Senior Grondkundige Hoe en waarom invoortoedienings? In hierdie artikel word invoortoedienings na verwys as die praktyk waar biostimulante met of sonder voedingselemente in ’n vloeibare vorm op die saad of naby die saad toegedien word. Die algemene praktyk is om ongeveer 100 L water per hektaar neer […]
Vruggrootte op sitrus
Jakkie Stander, Kommersiële Hoof: Produkte Marné de Vries, Tegniese en Kommersiële Hoof: Vrugte en Neute, Enzo Jansen van Rensburg, Senior Grondkundige en Hortoloog Vele voordele By sitrusproduksie is vruggrootte een van die belangrikste bepalers van winsgewendheid. Groter vrugte is vroeër ryp, kan dus vroeër en vinniger geoes word, maak meer kartonne vol en subsidieer […]
PICKLOGGER™ – Vind die regte antwoorde vinniger
Werner Coetzee: Kommersiële Hoof: PICKLOGGER™ | Jan-Willem Boonzaaier: Kommersiële Hoof: Dienste Opbrengskaarte vir boordgewasse Presisieboerdery en die gebruik van data vir beter besluitneming is integraal tot die volhoubare sukses en winsgewendheid van ‘n boerdery. Produsente wat hul toespits op presisieboerdery en optimale winste najaag, moet nou met ‘n baie fyn oog na variasie in produksie […]
Koolhidraat-kompetisie tussen sinkorgane voor blominduksie by sitrus
Dr. Elmi Lötze (Hoof van ITEST™CARBOHYDRATES en ITEST™LEAF) en Dr. Jakkie Stander (Kommersiële Hoof: Produkte) Inleiding In Suid-Afrika word sitrusvrugte geoes vanaf Maart tot September. Baie klem word dan geplaas op bestuurspraktyke wat vrugkwaliteit bevoordeel. Dus is die fokus hoofsaaklik op die huidige oes wat gedurende daardie fase die sterkste sink vir koolhidrate is. […]
Variable rate applications – a return on investment
Marnus Ferreira: Head Soil Scientist The application of variable-rate soil amendments such as lime or gypsum, is nothing new in the agricultural industry and the related benefits in terms of cost savings and soil fertility are widely recognised. Many producers, however still do not make full use of their variable rate systems during fertiliser applications […]
Alternerende drag in avokado’s
Dr. Elmi Lötze (Hoof van ITEST™CARBOHYDRATES en ITEST™LEAF), Waldo Krige (Senior Hortoloog) en Wilmé Brown (Plant Fisioloog) Inleiding Die effek van alternerende drag in avokado’s is steeds ʼn uitdaging. Die verskynsel is reeds baie suksesvol aangespreek in bladwisselende gewasse soos appels, pere en sekere steenvrugte deur middel van groeibeheer en chemiese manipulasie van vruggetalle. Die […]
