Potash
Key points
•
Cost effective way of improving and maintaining K indices
•
Reduced risk of leaching on light soils
•
Immediately available
•
Potash availability in line with crop growth demands
- Stronger healthier plants
General background notes on potash:
•
Potash index should be 2 (England and Wales) for adequate growth.
•
If indices are under 2 then larger amounts of potash should be applied
to replace and improve index over a period of years.
•
Grass yield increases of 65% have been shown on soil K index 0.
(28% on soil index 1)
•
Light land requires more potash than heavy land. Low potash reduces
grain yield, quality and vigour
•
Potash in potatoes is the most important nutrient affecting quality,
tuber size, dry matter, storage and drought and disease resistance.
Staggers
The level of potassium in the rumen is a factor known to inhibit
magnesium absorption in the rumen. Lactating cows secrete magnesium
in the milk so can be particularly prone to Staggers.
Fibrophos contains a less soluble form of potash than some other
fertilisers, and also contains good levels of magnesium to help
compensate so cattle are at less risk with Fibrophos than other fertilisers.
However, it is recommended that stock are not grazed on land fertilised
with Fibrophos for up to 21 days or unless a good rain has washed the
product off the foliage.
