Sand and soil analyses: choosing the appropriate sand for the rootzone
This video shows how to measure the exact amount of sand applied.
I suggest using the OM246 calculator to find details about organic matter accumulation and sand topdressing rates for your site.
Nutrient uptake in the soil
In general, the soil will supply enough Ca and Mg to meet grass requirements. Nitrogen is usually required to stimulate extra turf growth. Irrigation water or soil organic matter usually provide enough S, but sometimes S can be beneficial. Soil P and K may or may not be sufficient to meet the grass requirements, and soil tests (soil nutrient analyses) are a good way to check if the soil can supply what the grass will use, or if fertilizer is necessary.
