Interpretation of Soluble Salt Tests and Soil Analysis
Controlling and accurately measuring the soluble salts in the soil solution is a continuous problem for most flower growers, especially where crops are grown in predominately sandy soils. Salts accumulate in the soil primarily from applied fertilizer and salty irrigation water, and small amounts are contributed by decaying organic matter. Soil soluble salts are composed predominantly of ammonium, calcium, magnesium, potassium, sodium, bicarbonate, chloride, nitrate and sulfate ions.
