ZINC PHLOEM™: Improving nutrient delivery and plant physiological status
ZINC PHLOEM™: Improving Nutrient Delivery and Plant Physiological Status By Rochelle Thuynsma, Head of Products: Technical Role of Zinc in Plant Physiology Plant growth and development depend on a sufficient supply of zinc (Zn). Photosynthesis, the main metabolic pathway in plants, can be significantly reduced by Zn deficiency, leading to a decrease in photosynthetic capacity, […]
Effective inoculation of soybean
Effective inoculation of soybean By Dr. Stefan van Wyk, Victus Bio Left sides: Plants inoculated using producer’s standard practices.Right sides: Plants inoculated with RX-N Soybean™: Ultra. The Need for Nitrogen Nitrogen is an essential macronutrient required for the growth and development of plants. All vital processes in plants need nitrogen as a main building block […]
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 they are 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 […]
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 the […]
Variable rate applications based on your soil
Variable rate applications based on your soil by Marnus Ferreira, Head of Soil Science Yield data still a popular choice The application of variable rate soil corrections such as lime and gypsum is not new to the agricultural industry while the benefits in terms of cost savings and soil fertility flowing from these applications are […]
Transforming agriculture through satellite imagery
Transforming agriculture through satellite imagery By Werner Coetzee, Head of Yield: PICKLOGGER™, IFLY™, PPM™ In the ever-evolving agriculture landscape, the emergence of satellite imagery has sparked a transformative revolution for producers worldwide. One such ground-breaking service, IFLY VERDE™ by Airbus, is reshaping the way we perceive and manage crop cultivation. Unveiling IFLY VERDE™ A bird’s-eye […]
Crop carbohydrate status and MAJESTIC™
Crop Carbohydrate status and MAJESTIC™ By Rochelle Thuynsma (Head of Products: Technical) and Dr. Elmi Lötze (Head of ITEST™CARBOHYDRATES and ITEST™LEAF) Introduction The carbohydrate status of a tree/organ is dependent on factors influencing photosynthesis in the leaves, the accumulation of sugars and starch in the leaves and the translocation of sugars towards the other sinks(1). […]
Carbohydrates and flower development in avocados
Carbohydrates and flower development in avocados by Dr Elmi Lötze (Head of ITEST™CARBOHYDRATES and ITEST™LEAF) and Wilmé Brown (Plant Physiologist) Flower development requires energy Avocado trees flower in abundance, though only a small percentage of these flowers set and develop into mature fruit. This process is influenced by carbohydrates and plant hormones. Carbohydrates (sugar […]
ITEST™ CARBOHYDRATES analyses for pome fruit
ITEST™CARBOHYDRATES analyses for pome fruit by Dr Elmi Lötze, Head of ITEST™CARBOHYDRATES and ITEST™LEAF and Wilmè Brown, Plant Physiologist Biological indicator for management decisions The ITEST™CARBOHYDRATES service is now also available for pears and apples. Although the impact of carbohydrates on pome fruit cultivation has been investigated locally for many years, a commercial service making […]
How your avocado orchard benefits from carbohydrate analyses
How your avocado orchard benefits from carbohydrate analyses By Dr Elmi Lötze (Head of ITEST™CARBOHYDRATES and ITEST™LEAF) and Wilmé Brown (Plant Physiologist), Agri Technovation Carbohydrates as physiological indicator of plant status The use of carbohydrate analyses to study plant performance is an established practice in the research environment (Wolstenholm, 1987; Whiley et al., 1988; […]
