Calcium lends the plant its firmness and regulates pH. Excess calcium raises the pH in the soil, reducing the ability of plants to absorb nutrients. The less calcium the more acidic (pH 7.0) the soil. Some plants thrive in somewhat acidic soil, such as heather.
\nPlants absorb calcium and rain and groundwater wash away calcium: calcium slowly disappears from the soil making it acidic. Fertilizers with agricultural lime replenish the amount of calcium.
\nCalcium deficiency manifests itself in several ways: in lettuce<\/a>, cabbage and sprouts, tipburn occurs, the edges of the leaves yellowing and turning brown.
\nCalcium deficiency causes blossom end rot in tomatoes and peppers as well as ‘bitter pit’ in apples: around the core of the apple, glassy, translucent spots appear in the flesh: the cells leak cell fluid. The taste of those spots is bitter.
\nSome apple varieties are prone to bitter pit: including Bramley apples.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=”yes”][vc_column width=”1\/3″][vc_custom_heading text=”Where to find” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1537946500082{background-color: #536895 !important;}”][vc_column_text el_id=”entrytxt” el_class=”entrytxt” css=”.vc_custom_1702209113825{padding-left: 15px !important;}”]<\/p>\n
