Calcareous Soil

Calcareous Soil is a soil in which chalk (carbonate of lime) predominates. When in great excess it renders the colour a near approach to white, in proportion to that excess. No soil is productive which does not con-tain some chalk, or in which it exceeds nineteen parts out of twenty. From one to five per cent, is the usual proportion in fertile soils. Calcareous soils are rarely productive; they are so feebly retentive of moisture that the crops upon them are burnt up in summer; and they reflect the sun's rays so fully, that vegetation is late upon them in spring. The best addition to such soils, to improve their staple, is clay.
