Sulphur is a vital secondary crop nutrient. It can be delivered in sulphate, thiosulphate and elemental form. The range of product and process options are outlined.

Brazil’s agricultural industry continues to expand at the same time that most of its nitrogen fertilizer industry has shut down. Meanwhile, Venezuela continues to deal with the consequences of years of underinvestment and mismanagement, and elsewhere, gas discoveries in other parts of the continent have not led to the new plant construction boom that had once been hoped for.

Small, soft fruits such as blueberries, raspberries and strawberries thrive on fertile, well-drained soils rich in organic matter. Their nutrient needs can vary widely according to yield expectations and soil characteristics.

Applying dissolved fertilizers via micro-irrigation systems or leaf sprayers offers commercial fruit and vegetable growers clear-cut gains – in terms of input costs, nutrient use efficiency, labour, time and energy.

The drive for ever higher crop yields is shifting the focus onto secondary nutrients such as calcium and magnesium. In this article, we look at the role of magnesium and calcium in crop nutrition and the main fertilizer product options.

Temperature dependent rate constants for the hydrolysis of CS2 and COS across Claus Al2 O3 and TiO2 catalysts are valuable tools for the design and optimisation of new, as well as existing, sulphur recovery units. In this context, Alberta Sulphur Research Ltd (ASRL) has measured CS2 and COS hydrolysis rates over a range of temperatures for both Al2 O3 and TiO2 catalysts under start-of-run and, more recently, end-of-run first converter conditions. In this article Christopher Lavery, Dao Li, Ruohong Sui, and Robert A. Marriott of ASRL report on their methodology and the utility of the kinetics calculated from their data and draw comparisons between the start-of-run and end-of-run results.

New research findings strongly suggest that iodine behaves as a plant nutrient. SQM International has been quick to follow up on this discovery by launching a new speciality iodine fertilizer for fertigated crops.

Sulphur is becoming an increasingly vital crop nutrient, due to a combination of lower sulphur deposition from the atmosphere, the increasing prevalence of high-analysis fertilizers and higher cropping intensity.

Liquid fertilizers are emerging as a high growth, multibillion dollar market. Their growing use is linked to trends such as no-till farming and the greater adoption of precision agriculture. Leading producers and products are highlighted.

The precision mixing and granulation of mineral and organic fertilizer ingredients are essential to meet growing market demand for high-value, complex crop fertilizers. Furthermore, the ability to mix and granulate in a single machine offers fertilizer manufacturers both operational and product quality advantages over traditional granulation methods.
