Newly developed flotation reagents are improving the selectivity and grade/recovery of phosphate and potash concentrates.

The consistency and integrity of fertilizer granules are key when producing a high-quality product for crop nutrition. Granulation aids help achieve this by increasing crush strength, improving size distribution and reducing recycling volumes during manufacturing. Christina Konecki of Arkema-ArrMaz outlines how their performance can be properly evaluated.

Conventional fertilizers can be transformed into enhanced efficiency fertilizers (EEFs) using coating agents and inhibitors. Greater use of EEFs, by preventing nutrient losses and avoiding excess nutrient supply, can help global agriculture become more sustainable, as Urvi Mathur of Neelam Aqua explains.

Yield, quality and profitability are the primary focus for the modern potato grower. But these objectives need to be balanced against the need to reduce the environmental impacts that result from cultivating the world’s fourth-biggest food crop. Fertilizer International talks to David Marks of Levity Crop Science about how its unique approach to product development is helping farmers adopt more sustainable agricultural practices.

Dr Heike Thie l and Dr Wilm Fecke of K+S Minerals and Agriculture GmbH outline how better nutrient management can reduce potato yield losses during lengthy dry spells – and make better use of the available water.

Polysulphate is a new multi-nutrient fertilizer mined in the UK. Its unique characteristics and mix of nutrients make it especially suitable for potato crops, explains Patricia Imas, chief agronomist at ICL Innovative Ag Solutions (IAS).

As sulphur recovery units operate at progressively higher temperatures, creep stress in the furnace refractory lining can lead to deformation or even failure of the bricks and require the shutdown of the SRU. UK-based DSF Refractories have developed a product which minimises creep stress damage at high temperatures, for a longer-lived furnace lining.

Sulphur is becoming an increasingly important crop nutrient, due to a combination of lower airborne sulphur emissions, the increasing prevalence of high analysis fertilizers, and higher cropping intensities.

The latest developments in the recovery and commercialisation of fluorosilicic acid, rare earth elements (REEs) and uranium co-products associated with phosphoric acid production.

Boron is a key micronutrient required by fruit and vegetables and crops such as corn, cotton, rice, soybean and sugar cane. The agricultural importance of boron and the wide range of products on the market are described.
