Abstract

Abstract

In laboratory tests the addition of Ca greatly decreased the solubility of native and applied P in six different muck soils. Reducing the amount of Ca in the soil solution by applying materials having Ca-bonding properties increased the solubility of P in a muck soil. In a greenhouse experiment, tomatoes grown in muck soil limed and fertilized with phosphate in different amounts showed the depressing influence of lime on yield, P content in the plant tissue, and total P uptake by the plants. Liming increased the Ca content in the plant tissue.
