Pimento grows well in semi-tropical lowland forests with a mean temperature of 18–24 °C, a low of 15 °C and a maximum of 32 °C. WebIn contrast, phosphorus, manganese and boron are locked up in insoluble iron and aluminium phosphates at around pH 7.5. Plants growing on these soils can suffer from deficiency diseases (for example, phosphorus deficiency, which shows as yellowing of the leaves). This is particularly true of plants that are not adapted to grow at high pH. WebChalky soil can be clayey or sandy, but is notable for the many fragments chalk or limestone that it contains.
