OAO Uralkali sees a high risk that its Solikamsk-2 potash mine east of Moscow will be completely flooded, forcing the world’s biggest producer of the fertilizer to abandon a site that makes up almost a fifth of its capacity, Bloomberg News reported.
If the use and reuse of the finite resource phosphorus as a nutrient for plants were to be handled with greater care worldwide it would become possible to produce sufficient food for the global population in and after 2050.
Many fertilizer recommendations are made based on a composite soil sample representing the average fertility of the entire field. This approach fails to address the spatial variability of nutrients in the field resulting from changes in soil type, topography, previous cropping history, and many other factors.
Canada's Potash Corp of Saskatchewan, the world's largest fertilizer producer, is sizing up its chances of gaining control of four companies in which it holds minority stakes, Chief Executive Officer Jochen Tilk said on Wednesday.
Traditionally, farmers apply phosphorus (P) and potassium (K) fertilizer and lime in the fall when there is more time and equipment available and soil compaction may be less of a concern. This simplifies spring operations and streamlining planting. This year (2014) is somewhat different because of delayed planting and maturity.
Global potash prices are unlikely to spike from the shutdown of a flooded Russian mine, as producers will likely re-start idled capacity to pick up the slack, Indian fertilizer company Coromandel International Ltd said last week.
There have been many questions about fall versus spring applications of phosphorus (P) and potassium (K) to soybeans. Does it really matter if P and K are applied in the fall or in the spring? We looked at published studies to see what we could find.
