Recent investigations have shown that, in addition to a needs-based nutrient supply, the prevention of stress situations in all growth phases is of special significance with regards to obtaining high yields.
Maintaining the photosynthetic capacity is the key to high mass growth. This effect is visible by an intense and long-lasting green colouration of the foliage. As long as the plants are green, yields are being produced.
VULKANO contains PGA (pyroglutamic acid) as a foliar fertiliser, responsible for the GREENING EFFECT on the plants.
Pyroglutamic acid is a natural building block for protein metabolism and plays a central role for nitrogen metabolism as a protein-forming amino acid. Sufficient pyroglutamic acid content in the plant ensures optimum N assimilation efficiency. This is always important when the plant is subject to stress. Stress can have abiotic origins such as extreme temperatures, dryness, waterlogging or herbicide stress, but also phases of intense growth such as tillering, shooting and ear emergence can considerably reduce the pyroglutamic acid levels in the plant. If the pyroglutamic acid level in the plant drops, the N cycle stagnates.
As a result, less nitrogen can be assimilated – in extreme cases, the synthesis cycle is reversed and ammonia accumulates in the plant tissues, clearly shown by leaf yellowing and necrosis.
Such stress situations can occur several times throughout the vegetation period. Timely application of VULKANO helps the plants to rapidly recover from such phases and to continue exploiting their full yield potential.
VULKANO fills the plant’s reserves of natural pyroglutamic acid and ensures continuous growth and optimum use of nitrogen.
Furthermore, VULKANO provides a complete and readily available nutrient supply through the leaf when the uptake of individual nutrients through the soil is limited.
