The revolutionary mid-row ripper with Vibrosoiler® technology
Marnus Ferreira, Technical Head of Soil Science and ITEST™ SOIL The challenge of established orchardsThe improvement or correction of soil-related limitations in existing orchards has presented many a challenge to producers in the past. Up to now, using available technologies, it has been very difficult to fix the impact of mistakes made or shortcuts taken […]
Redefining Kelp: The science behind KELPURA™ in fruit crop phenology
Rochelle Thuynsma, Head of Products: Technical KELPURA™ is a pure liquid kelp-based plant biostimulant derived from the South African kelp species Ecklonia maxima. It is produced using a proprietary room-temperature extraction technology that preserves the integrity of the kelp’s natural bioactive compounds, including phytohormones, phenolic acids, amino acids and polysaccharides. This preservation is critical, as […]
SUGAR RUSH™: Not all sugar products are equal
Allan Huysamen, Business Development Manager – Adjuvants While many products in the market position themselves as sugar-based feeding stimulants, not all are created equally. SUGAR RUSH™ is a premium formulation which maximises feeding stimulation activity through its carefully designed formulation and specific sugar composition. While many products in the market position themselves as sugar-based feeding […]
CALCINATOR™: Foliar calcium for fruit crops
Dr. Jakkie Stander, Commercial Head of Products & Rochelle Thuynsma, Head of Products: Technical Calcium is vital for maintaining cell-wall structure, where it cross-links pectins in the middle lamella, as well as for membrane integrity and signalling processes. However, when applied foliarly, Ca faces several physiological and physical bottlenecks. Because Ca is transported predominantly via […]
Survival to symbiosis: Improved soybean nodulation in adverse in-field conditions
Claire Randolph (MSc), Victus BioCo-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 planting […]
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 […]
Stronger by nature: Calcium and silicon technologies
Rochelle Thuynsma, Head of 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 the […]
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 […]
Wine grapes: Bud break carbohydrates rule the roost
Wilmé Brown (Plant Physiologist) and Dr. Elmi Lötze (Head of ITEST™CARBOHYDRATES, ITEST™LEAF and Research and Development) Carbohydrates and viticulture The vine needs carbohydrates to survive the winter (the time during which leaves are absent and active photosynthesis cannot occur) and also to support vegetative growth during the coming season until new leaves emerge. While […]
Small grain leaf analyses tell a story
Nicola Kotzé, Senior Agronomist Dr. Elmi Lötze, Head of ITEST™CARBOHYDRATES and ITEST™LEAF Leaf analyses speak volumes Leaf analyses on small grains can identify mineral deficiencies even before visually observed, allowing farmers/growers to address deficiencies at an early stage, thus saving costs. Leaf analyses are generally used with great success in permanent crops, as well […]
