petrocalcic horizon वाक्य

Petrocalcic horizons are typically found in older soils and are considered a mark of advanced soil evolution.
Dryness, and in places also stoniness and / or the presence of a shallow petrocalcic horizon, limit the suitability of Calcisols for agriculture.
There is also some evidence that petrocalcic horizons can form " in situ " by alteration of limestone parent materials and alternating dissolution / precipitation of calium carbonates.
The parent material of duripan soils usually does not contain a large amount of calcium carbonate, and if there is an abundance of calcium, a Petrocalcic Horizon can form in conjunction with the duripan.
