Symbio gypsum is a quick and easy way to supply both calcium and sulphur to your soils. This product is most effective if used in soils with a pH>5.5. This is a greens grade granule (1-1.5mm).
• Correct balance of calcium and ensures availability of other key
• Substantially reduce nitrate and phosphate inputs
• Reduce the quantity of inorganic fertilisers needed for healthy
• Grass growth
• Low inorganic inputs help the development of a healthy soil food web for fine grass growth
Calcium is essential for strong plant cells and disease resistance in the plant. It is also the main component of the base cations and should make up at least 65% of the cations in the soil so the soil is kept open for air and water transfer and microbial growth. Too little calcium reduces nitrification and phosphate uptake.
50-100g/m2 at any time of year. Mix with top dressing or apply by itself – brush into tine holes after aeration
Apply annually until soil calcium levels reach desired
For best results your soil should be analysed for all nutrients, organic matter, cation exchange capacity and conductivity.
