Potash advice

POTASH shortfalls could cut nitrogen efficiency this spring, so hitting cereal margins, advises Richard Martin of Terra Nitrogen.

"Trials data clearly shows that higher P and K status soils grow more robust cereal crops which respond better to nitrogen and are therefore more cost-effective to grow." To avoid the problem apply potash with nitrogen as the first top dressing, Mr Martin suggests.

Terra products containing K include Kaynitro and Kaynitro Gold. Such an approach is more economic than an NPK compound, he claims.
