This document summarizes the results of pasture harvest trials comparing control paddocks to paddocks treated with Great Land products. The trials found that treated paddocks produced significantly more dry matter per hectare than control paddocks, with gains ranging from 2% to 161% depending on the region. Dairy farms that grazed cows on treated pastures saw increases in milk production, decreases in somatic cell counts, and improved farm profits compared to periods when cows grazed control pastures. Overall, the trials demonstrated that higher pasture production enabled by Great Land treatments can increase milk solids output and farm profitability.

1. Pasture Harvest Trials
Pasture INTAKE is a major driver of milk production and farm profit
Trial Objectives:
Comparison of pasture harvested: Great Land Treated v’s Control
Method:
• Paired or Split Paddock trials
• Weekly measure of pasture DM/Ha, Treated & Control areas
• ‘Rising Plate Meter’ converts height to DM/Ha
• Same day every week for main season
• Underreporting arises from inability to capture pre and post graze

5. Pasture Harvest Trials
Other observations beyond pasture harvest gains
• Pasture uniformity, clover content, weeds
• Pastures lasting longer in dry condition (improved soil moisture)
• Grazing pressure and grazing uniformity
• Animal health, calf health (where larger portion of farm is treated)
Fact: 100,000 change in BSCC impacts milk production by 5% – subclinical

6. 7 Day Grazing Trials
Objective:
Measure influence of Great
Land treated pasture on
Milk Production
Method:
Graze nominated pasture for 7 day periods: Control > Treated > Control
Need at least one third of the farm as treated paddocks

9. Full Farm - Demonstration Case
Tasmania
Conventional Scenario
• Fertilisers dominated by urea (250-
350 kg N/yr), super phosphate,
muriate of potash
• Pastures not responding to N
applications, pastures thin and
limited clover.
• Weed problems
Results of Biological Approach
Over 5-7 years, with GL in FY15
• Milk & MS production increased
• BSCC reduced by > 100,000
• Revenue and profit increase
• Pastures more even, clover dense
and leaves double in size, root zone
much deeper
• Weeds under control
• Corby grubs significantly supressed
• Cows filling up on pasture more
quickly (nutrient quality), pasture
utilisation increased, stocking rate
increased,
• Fertility increased, portion of heifer
calves increased (consistently)
