Overseeding with iSeed®
Technical Information
|
• |
iSeed® is an advantage as an integrated part of routine scarifying and overseeding of young grassland and new re-seeds. |
|
• |
Overseeding is preventing weed grass ingress that leads to rapid sward decline in later years. |
|
• |
The overseeding system works by annually topping up young swards with productive ryegrass and clover thus preventing weed grasses from developing within the sward. |
|
• |
Overseeding significantly improves the productive life and quality of a sward with yield and quality improvements of up to 44%.
|
In addition to the outstanding yield benefits shown above following this extensive 4 year trial, all other quality measures also showed significant improvement over the standard control.

Field Preparation: Remove all surplus grass growth by cutting or hard grazing. Scarify the area in opposite directions using a suitable grass harrow.
Sowing: Sow at the same time as scarifying with an appropriate iSeed® treated GrassMax overseeding mixture. Immediately after sowing roll the field to consolidate the ground and ensure good seed to soil contact.
Timing: Immediately after the last silage cut of the year or after a hard graze in the spring or autumn.
Fertiliser: All establishment fertiliser requirements are contained within iSeed coating. Do not apply any other fertiliser for 4-6 weeks.
Livestock re-introduction:
After Cutting (wait until existing grass has fully recovered). After Grazing (Keep livestock on for 10-15 days after sowing then remove livestock and allow sward to recover).
iSeed® Sets new standards in Seed treatment technology
iSeed® nutrient seed coating for forage seed
iSeed® is a coating applied to grass and clover seeds which contains selected amounts of essential nutrients for establishment which are immediately available to the emerging seedling. These nutrients supplement those growth elements contained within the seed structure, thus enhancing the vigour and the speed with which the plants develop to produce strong root growth coupled with the clearly more vigorous shoot and stem development seen above ground.

Feeds only the seed not the weed or surrounding grass |
|
• |
Significantly improves uptake efficiency |
|
• |
Better root and shoot extension |
|
• |
Up to 30% more viable plants per Ha |
|
• |
Improved stress tolerance |
|
• |
Environmentally friendly |
|
• |
No application costs |
|
• |
Highly cost effective at today's fertiliser prices

Improved establishment and higher yield
With iSeed®, the uptake of these essential nutrients provides for a stronger and more vigorous plant which, when established, will provide an extra 5-15% more dry matter in the first cut. Trials have shown that iSeed® treated seed will establish up to 30% more viable plants per acre making establishment more predictable.
Enhanced nutrient uptake and stress resistance
The nutrients in iSeed® are located exactly where they are most needed. They enhance root and shoot development, particularly important when the plants are under stress. Small seeds such as grass are sown within 1 cm of the soil surface and this area of the soil strata is very prone to drying out, thus causing stress at a very early stage of the seedling's growth.
iSeed® is easy to use
With iSeed® the seed weight is higher than normal thus ensuring good soil contact, essential when overseeding. There is no need for specialised equipment to establish a crop treated with iSeed®. A standard iSeed® coating from DLF-TRIFOLIUM contains nitrogen and phosphorus. 1 kilo of seed treated with iSeed® consists of 500gms of seed, 100gms of N and 20gms of P, the balance being coating materials. iSeed® compares favourably in price to conventional seed bed fertiliser, the advantage being greater reliability coupled with the many additional benefits listed above.
