Bulb, root or tuber vegetables.
This group includes onion, garlic, leek, carrot, potato, beetroot, radish, and sweet potato, characterized by underground harvested organs whose shape and development depend strongly on soil type and growth uniformity.

Garlic fertilization requires precision: it is sensitive to excess nitrogen and to shortages of potassium and sulfur. It needs good early phosphorus and balanced nutrition during bulb enlargement for uniform calibres and good storability. |
|
Onion requires balanced fertilization to ensure uniform growth and proper bulb formation. Its shallow root system makes it dependent on fertile, well-structured soils where continuous nutrient availability and organic matter are essential to maintain vigour and achieve homogeneous, high-quality yields. |
|
The potato crop has high nutritional requirements from the earliest stages of development, making it essential to ensure an adequate supply of nutrients from planting. A proper balance of nitrogen, phosphorus, and potassium is key to promoting strong early growth, root system development, and correct stolon and tuber formation, ultimately determining both yield and final crop quality. |
