Soil: Calcium opens up (flocculates) the soil, improving structure and allowing roots, earthworms, oxygen, water and microbes to move freely through the soil.
Plants: Calcium is often referred to as the ‘trucker of all minerals” in relation to its role in mobilizing other nutrients.
Plant Deficiency Symptoms: Stunted root systems and a lack of vegetable vigour. Blossom end rot in tomatoes, capsicums and zucchini. Internal browning or blackening of celery, potatoes and Brussels sprouts. Deformation and Necrosis of young leaves.
Good soil structure associated with correct calcium levels.
Avoid soil crusting. Soils are harder to damage and recover sooner after poaching or compaction when exposed to traffic by machinery or animals in wet conditions.
Calcium neutralizes soil acidity.
Calcium plays a critical role in improving soil structure and quality.
Improves water percolation.
Increases root development.
Only N and K are required in larger amounts by plants.
