Abstract

Various investigators have shown that carbon dioxide is important in the soil in making the plant food elements available. As a result attempts have been made to use solvents which are similar to carbon dioxide in their solubility effects on soil phosphorus. In many cases, the available phosphorus as measured by these solvents has correlated rather well with crop responses to phosphate fertilizer in the field, but the correlation is not perfect in all soils.
