A proper fertilization programme is necessary to sustain both citrus productivity and soil fertility over the longer term. ICL agronomists Fabio Vale, William Wang, Patricia Imas and Francisco Morell outline the nutrient needs of citrus fruit – a regionally important crop in the Americas, Europe and China.

We report on fertilizer production, consumption and pricing in the US market. The country’s fertilizer industry, ranked fourth globally in terms of total production capacity, has grown and developed alongside its increasingly sophisticated domestic agricultural sector.

Citrus fruit growers are an attractive end-market for fertilizer suppliers due to the high K and N requirement of this widely-cultivated cash crop and the efficacy of fertigation and foliar spraying. We examine the nutrient needs of citrus trees and how balanced application of fertilizers helps maximise citrus fruit quality and yield.

The cadmium and heavy metal content of sedimentary phosphates are of great concern. This has seen industry raw material consumption shift towards igneous phosphates or the blending of phosphate rocks from different sources. While rock blending can successfully reduce the heavy metal content of superphosphates, it needs to be accompanied by careful process adjustments, as Ian Hancock , Bradley Pulverizer’s vice president sales & operations, explains.

Market Insight courtesy of Argus Media. Urea: Prices in general fell further in late October. Suppliers in most regions were forced to accept lower than expected net-backs due to low import demand and high producer inventories. India was the exception with IPL securing 1.7 million tonnes of urea at $400-404/t cfr under its 20th October tender.

While producing ammonia with hydrogen from electrolysis remains expensive, large scale lower carbon ammonia has focused on carbon capture and storage from existing plants, so-called ‘blue’ ammonia. But exactly how green is blue?

With the current focus on decarbonising ammonia production, Tom Davison of Johnson Matthey explains the important role of high activity ammonia synthesis catalyst in the production of green ammonia.
