GrassMax

 

GrassMax Base has been specifically designed for new reseeds where subsequent overseeding is routinely intended.

This principle allows the use of significantly higher yielding grasses and can increase annual yields by up to 30% compared to more traditional mixtures. Routine overseeding will be required however to maintain plant numbers at the necessary levels to achieve these yield benefits.

 

All mixtures now available with iSeed

HF GRASSMAX - CUT

For new reseeds where subsequent overseeding will occur 

SOLID   Hybrid Ryegrass (T)
CITELIAC  Hybrid Ryegrass (T)
MAGICIAN  Intermediate Perennial Ryegrass (T)
HF CUTTING CLOVER BLEND  White Clover
  • 10 kg/acre (35 kg/hectare) 
  • 100% Tetraploid grasses which are ideal for overseedings as they have the largest seeds and are aggressive establishers
  • Contains a high proportion of HF's unique Cutting Clover blend to ensure good clover production and survival under intensive silage management
  • No Clover option available on request

HF GRASSMAX - CUT With Red Clover

A specialist overseeding mixture containing a high level of Red Clover designed to introduce both new grass and Red Clover into silage swards.  This mix can also be used to prolong the life of existing Red Clover swards provided Eelworm is not a problem.

 SOLID   Hybrid Ryegrass (T)
 CITELIAC  Hybrid Ryegrass (T)
 CORVUS  Red Clover 

  • 10 kg/acre (25 kg/hectare)
  • All ingredients have large sward seeds and are capable of establishing in an existing sward
  • Grass component is 100% Tetraploid Hybrid Ryegrass which is sufficiently aggressive to compete and survive in a Red Clover sward
  • Grasses based entirely on Hybrid and Perennial Ryegrasses with the highest conservation yields on UK recommended lists
  • 30% Red Clover content to ensure a good plant population in the overseeded sward
  • Excellent forage quality from both Solid and Citeliac

 MAGICIAN Intermediate Perennial Ryegrass (T)
 CALIBRA Intermediate Perennial Ryegrass (T)
 DELPHIN Late Perennial Ryegrass (T)
 POLIM Late Perennial Ryegrass (T) 
 HF GRAZING CLOVER BLEND White Clover 

  • 10 kg/acre (25 kg/hectare)
  • Achieves SugarMax status with a high proportion of the top sugar yielding variety Calibra
  • Based entirely on Perennial Ryegrass varieties with the highest grazing yields on UK Recommended Lists
  • 100% Tetraploid grasses which are ideal for overseeding as they have large seeds and are aggressive establishers
  • Based entirely on Perennial Ryegrass varieties with the highest grazing yields on UK Recommended Lists
  • Very good Crown Rust resistance from both Polim and Delphin both of which receive very high resistance ratings from NIAB
  • Contains a high proportion of HF Grazing Clover blend containing varieties specially selected for their production and persistence under grazing
  • No Clover option available on request

Guidelines for successful overseeding

A typical sward

 Overseeding can

 sward performance
     
                                        
Field Preparation

  • Remove all surplus grass growth by cutting or hard grazing
  • Scarify the area in opposite directions using a wire tine grass scarifying harrow

Sowing

  • Sow at the same time as scarifying with up to 10 kg/acre (25 kg/hectare) of the appropriate Grassmax mixture
  • Where iSeed®  treatment is used, as the fertiliser effectively doubles the weight of the seed, the sowing rate is double that of untreated seed
  • Roll immediately after sowing to consolidate the ground, conserve moisture and ensure good seed to soil contact

Timing

  • With untreated seed, to ensure that competition from the existing sward is minimised, the optimium overseeding window is immediately after the last silage cut of the season or after a hard graze in the Spring or Autumn
  • Although the benefit of minimising competition from the existing sward also applies to iSeed® , the increased competitiveness of iSeed® reduces the dependence in timing and may offer the opportunity of a much wider sowing window

 

Livestock Re-introduction

  • After cutting wait until aftermaths have fully recovered
  • After grazing leave stock on for 10 days then remove and allow sward to recover
