calcareous soil

calcareous soil

(kălkâr`ēəs), soil formed largely by the weathering of calcareous rocks and fossil shell beds. Different varieties usually contain chalk, marl, and limestone and frequently a large amount of phosphates. They are often very fertile, as in the case of the buckshot soils of the S United States. Sometimes calcareous soils are flinty, thin, and dry. They often form a large part of the soil of deserts, which may prove very fertile when sufficient moisture for crops is applied.

calcareous soil

[kal′ker·ē·əs ′sȯil]
(geology)
A soil containing accumulations of calcium and magnesium carbonate.

Improvement of root growth, together with increasing nutrient availability (Table 3), application of both pure compost and biochar fortified compost increased total biomass and grain yield of maize planted on calcareous soil. The results in Table 4 show that the control treatment produced total biomass of 8.83 Mg[ha.sup.-1] (first maize) and 3.40 Mg[ha.sup.-1] (second maize) with 1.97 Mg[ha.sup.-1] (first maize) and 0.68 Mg[ha.sup.-1] (second maize), and the organic amendment treatment produced total biomass of 14.62-17.20 Mg[ha.sup.-1] (first maize) and 7.27-8.85 Mg[ha.sup.-1] (second maize) with 3.72-4.82 Mg[ha.sup.-1] (first maize) and 1.85-2.31 Mg[ha.sup.-1] (second maize).

We have previously shown that P applied as fluid fertiliser diffuses more and remains more potentially available (more isotopically exchangeable) to plant roots in calcareous soil than does P applied in granular form (Lombi et al.
T he calcareous soil can fix a lot more P than the sandy soil, and this is also reflected in the low soil test and the soluble P.After the adsorption maximum has been reached, the soil becomes very prone to P loss and potential pollution.
Habitat at the collection site, an abandoned adobe homesite littered with debris, was comprised of patchy mesquite, prickly pear, yucca, mixed grasses, and forbs growing on sandy and calcareous soil. Ecological associates included Cnemidophorus tesselatus and C.

[25], SSP being an acidic P fertilizer performed better than DAP for P uptake and soil test levels on alkaline calcareous soil. Similarly, in a two-year field experiment Chaubey and Kaushik [26] reported higher grain yield of wheat with SSP compared to DAP and attributed the low yield with DAP to more P fixation as a result of alkaline soil pH around its granule.
