Gypsum Soil Life is useful in the transition period in dairy cows two- four weeks pre- and post- calving, and can be used as an anionic salt to counteract the effects that high potassium and sodium concentrations have on increasing hypocalcemia.
Gypsum, a readily available form of calcium (Ca), is 100- times more soluble than lime and is more suitable for the digestive system during this period.
As soon as cows have calved, the gypsum can be dusted on. Dusting generally means around 5 0 percent of gypsum getting ingested. While spreading gypsum normally onto the soil can' t be relied on to give a significant short-term boost to calcium in the herbage (of the sort of levels likely to be req uired in early lactation).
The aim of any bulk spreading would be to improve soil structure and resilience to pugging etc. Gypsum is an important element in the pH balance of blood in the animal. With consistent chemistry and q uality, it provides readily available Ca and sulphur nutrients.
Dusting for the colostrum period (of high Ca demand) would typically be at around 300 grams (g) to 5 00g per cow per day.
For the 5 0 percent of the dusting that is ingested, it is generally assumed that there will be around a 70 percent absorption of the Ca, so 300g dusting delivers an estimated 105 g to the cow.
Gypsum is 100- times more soluble than lime and useful elsewhere in the farmer’ s regime, however, recognise there is a specific target timeframe during the cow's lactation.
Soil Life is a Biogro certified input material.
If integrated into feed or dusted, the application rates will vary based on the delivery mechanism.
