Mining major Anglo American is to invest up to $4 billion to complete its Wood-smith mine project in the UK.

Micronutrient products are one the fertilizer industry’s fastest growing segments. In response, ICL, Koch Agronomic Services, Levity Crop Science, Omex and SQM have all strengthened their micronutrient portfolios.

We look ahead at fertilizer industry prospects for the next 12 months, including the key economic and agricultural drivers likely to shape the market during 2023.

This UreaKnowHow.com round table discusses the process upset condition of a high urea concentration in the ammonium carbamate recycle. It is commonly known that the urea formation reaction from ammonia and carbon dioxide via ammonium carbamate is an equilibrium reaction and that the urea conversion in any urea plant is limited. That is why downstream of the urea synthesis section the urea is separated from the ammonium carbamate in a recirculation section. Ammonium carbamate is dissociated into ammonia and carbon dioxide gases by means of low pressure and the addition of heat. The ammonia and carbon dioxide gases are dissolved in water and recycled back to the urea synthesis section. The urea content should be minimal as urea in the ammonium carbamate recycle leads to lower efficiencies. What are the causes and remedies for a high urea concentration in the ammonium carbamate recycle? n

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.

After just 10 short years in business, there is a reason why Verdesian Life Sciences has lived up to its mantra ‘the Nutrient Use Efficiency People’. This is not just a slogan – it defines the company’s philosophy and culture. It also sums up Verdesian’s mission to help the world’s farmers do more with less through the company’s broad portfolio of sustainable nutrient efficiency products.

Effective and efficient wastewater management is a vital task that is being aided by the introduction of new treatment technologies. The recovery of economically-valuable nutrients from wastewaters is another priority.

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.

The fertilizer price and supply chain shocks caused by the war in Ukraine have supercharged the debate about the shift to more sustainable and efficient crop nutrition – with farmers and governments urgently looking for different approaches to maximise crop productivity.

Producing efficient fertilizers that deliver nutrients directly to crops in exactly the right amounts has clear economic and environmental benefits. Recent advances in controlled-release and stabilised fertilizer technology are highlighted.
