Directions for Use

Gardens and Landscapes: For reducing soil acidity, broadcast and incorporate 0.5 - 6.75 kg per 10 m2 (1 - 13.8 lbs per 100 ft2). For equal pH adjustment sandy soils require a lower rate compared to clay soils and those high in organic matter. Consult an agronomist to determine appropriate rates for your garden soil.

Field: Consult an agronomist to determine an appropriate application rate. Typical rates are between 560 to 6700 kg per ha (500 to 6000 lb per acre).

Top-dressing hanging baskets, potted plants, and planter boxes: Mix in 15 ml per 4 L (1 tbsp per gallon) of soil or growing media. Apply monthly or as desired. Effects of this product on soil pH may take in excess of 1 year to be fully realized.
