Irrigated Dairy \u00b7 Murray-Darling Basin \u00b7 Multi-Cut Management<\/div>\n

The specific equipment, timing, and storage challenges of high-frequency multi-cut lucerne and ryegrass silage on centre-pivot or flood-irrigated dairy farms \u2014 and why the rules that work for dryland farms don’t apply here.<\/p>\n<\/div>\n<\/div>\n

\n
\n

The Irrigated Dairy Silage System \u2014 Why It’s a Different Discipline<\/h2>\n

Dairy farms operating under irrigation in the Murray-Darling Basin \u2014 concentrated along the Murray River corridor from Echuca to Mildura in Victoria, along the Murrumbidgee Irrigation Area (MIA) around Griffith and Leeton in NSW, and through the Goulburn-Murray Irrigation District in northern Victoria \u2014 produce silage at a frequency and consistency that dryland farms cannot match. A centre-pivot irrigated lucerne stand cut at 28 to 35 day intervals produces 5 to 8 cuts per season; a flood-irrigated ryegrass-perennial blend under managed rotational grazing with silage inserts produces 4 to 6 silage cuts.<\/p>\n

The operational implication is that an irrigated dairy farm producing 1,500 to 2,500 bales per season is doing so across 5 to 8 distinct cutting events rather than the 1 to 2 events of a comparable dryland operation. Equipment and process failures that a dryland farm can absorb once per season \u2014 a broken wrapper, a poor-quality batch from sub-optimal wilting \u2014 have 5 to 8 times the opportunity to occur on an irrigated operation. And the feed quality implications are correspondingly larger: a dairy herd fed from irrigated silage reserves eats silage that was made across 5 or more distinct cutting dates, and quality variation between batches directly impacts daily milk production in a way that’s more difficult to manage in a TMR system.<\/p>\n

This article is specifically for irrigated dairy operators in the MDB who are managing or considering managing their own baling operation for the full multi-cut season. For the broader question of how high-volume dairy operations select their baling setup, our article on the best silage baler setup for high-volume dairy operations<\/a> covers the machine selection framework \u2014 this article focuses on the specific operational management of five-plus cuts per season.<\/p>\n<\/div>\n

Why Cut 3 and Cut 4 Are the Most Critical \u2014 and Most Risky<\/h3>\n

First-cut lucerne in September and October benefits from cool wilting conditions \u2014 overnight temperatures of 10 to 15\u00b0C slow aerobic microbial activity in the fresh wilted windrow, allowing 24 to 36 hour wilt periods without significant quality loss from field heating. Third and fourth cut material in November to February faces the opposite problem: ambient temperatures of 28 to 40\u00b0C in the MIA and Goulburn Valley mean that a fresh lucerne windrow begins aerobic heating within 4 to 6 hours of cutting. Wilting material that has been on the ground for 24 hours at 35\u00b0C ambient has lost more dry matter to field respiration than material wilted for the same period at 15\u00b0C.<\/p>\n

The operational response that experienced irrigated dairy farmers in the MIA have converged on for third and fourth cut silage is: cut in the late afternoon (3 to 5 PM), rake at dawn the following morning (6 to 7 AM) when dew on the surface has evaporated but the ambient temperature is still below 25\u00b0C, bale through the morning, and complete wrapping by early afternoon before peak heat returns. This 16 to 18 hour cut-to-wrap cycle is only feasible when the equipment is on-farm and the operator can manage the timing precisely \u2014 it is not achievable with a contractor who arrives when available.<\/p>\n<\/div>\n

\n

Equipment Throughput Requirements: What Five Cuts Demands<\/h2>\n

The Wrapper Becomes the Throughput Bottleneck on a Multi-Cut Operation<\/h3>\n

On a dryland farm making 1 to 2 cuts per season with a 2 to 3 week baling window, the bottleneck is almost always the baler \u2014 the wrapper can keep up with any reasonable baling rate. On an irrigated five-cut operation where 300 to 400 bales need to be completed in a 4 to 6 hour weather window during the hottest part of the season, the bottleneck shifts to the wrapper. A standard single-unit wrapper processes one bale every 45 to 75 seconds \u2014 a throughput of 48 to 80 bales per hour when moving between bales is included. At the same time, a well-operated round baler in good lucerne windrows produces 60 to 90 bales per hour.<\/p>\n

The rate mismatch means that at peak throughput, the baler is waiting for the wrapper. Two solutions exist: a combined baler-wrapper that eliminates the queue by integrating the operations, or a separate wrapper that operates in parallel with the baler on a second tractor \u2014 allowing the baler to continue producing while the wrapper catches up. For an irrigated dairy operation making 400 bales per cutting day in a 5-hour window, the separate parallel-operation approach (baler on tractor 1, wrapper on tractor 2) achieves the throughput target while the combined-unit approach falls short by approximately 30%.<\/p>\n

The 9YCM-850 bundling film wrapping machine<\/a> is the appropriate separate wrapper specification for MDB irrigated dairy operations: its programmable revolution counter applies exactly 6 layers without operator counting (eliminating the under-wrap error that occurs when operators are tired at hour 4 of a long harvest day), its 750 mm film roll format is compatible with the 1.25 m bale diameter standard across MDB dairy farms, and its throughput rate of 55 to 75 bales per hour closely matches the baler output in a parallel two-tractor configuration.<\/p>\n

Baler: Variable Chamber for Variable Cut Conditions<\/h3>\n

Lucerne cut 1 in September from a winter-rested stand produces a significantly heavier windrow than cut 5 in March from a stand that has been cut 4 times without a moisture application interruption. A fixed-chamber baler set for the heavy first-cut windrow will under-fill on the lighter fifth-cut material; set for the lighter cuts, it over-stresses in the heavier first-cut. A variable-chamber baler self-adjusts to the windrow weight of each cut, maintaining the 180 to 220 kg DM\/m\u00b3 density target regardless of cut number. For a five-cut irrigated dairy operation, the variable chamber is not a premium option \u2014 it is the specification requirement that delivers consistent bale quality across a season where windrow weight varies by 30 to 50% between cuts.<\/p>\n

The 9YG-1.25A variable-chamber round baler<\/a> handles the full range of MDB irrigated lucerne and ryegrass silage conditions across five cuts, producing consistent 1.25 m bales at target density from the heaviest first-cut windrow to the lightest late-season cut.<\/p>\n<\/div>\n

Managing Silage Quality Across Five Distinct Cuts<\/h2>\n

Why Multi-Cut Silage Needs Batch Tracking<\/h3>\n

A dairy farm feeding from a multi-cut silage inventory is mixing bales from 5 or more distinct fermentation batches, each made at slightly different moisture levels, different DM contents, and with different ambient fermentation temperature profiles. The nutritional profile of cut 1 September silage (cool ferment, slower pH drop, higher WSC preserved) differs measurably from cut 4 February silage (fast ferment, rapid pH drop, some aerobic DM loss during wilt). Feeding these bales interchangeably without knowing their relative quality introduces nutritional variation in the TMR that affects daily milk production.<\/p>\n

Batch-tagging bales by cut number at wrapping \u2014 a strip of differently coloured tape, a spray paint code on the end face, or a simple bale numbering scheme logged against cutting date \u2014 allows the farm manager to sequence bale opening in a controlled way (feeding poorest-quality bales first, best-quality in peak lactation), and enables silage quality testing to be targeted at representative samples from each cut rather than random samples from a mixed inventory.<\/p>\n

Inoculant Use on a Multi-Cut Irrigated Operation<\/h3>\n

The case for LAB inoculant use on irrigated dairy silage is strongest in cuts 3 and 4, when high ambient temperatures during wilting and fast field moisture loss create conditions where the silage fermentation substrate (WSC content of the crop) may be lower than in spring cuts. In February and March, lucerne regrowth under heat stress has lower WSC (4 to 7% DM versus 7 to 11% in spring growth) \u2014 more challenging fermentation substrate precisely when the wilting conditions are most aggressive. Applying a homofermentative LAB inoculant at 1 \u00d7 10\u2076 cfu\/g fresh weight at the baler pickup in cuts 3 and 4 is standard practice on well-managed MDB irrigated dairy operations; it is optional but recommended for cuts 1, 2, and 5 where fermentation conditions are more favourable.<\/p>\n<\/div>\n

\n

Water Management and Silage Timing \u2014 The Irrigation Interaction<\/h2>\n

Pre-Cut Irrigation Timing<\/h3>\n

Lucerne paddocks under flood or sprinkler irrigation should receive their pre-cut irrigation allocation 10 to 14 days before the intended cutting date \u2014 not in the 7 days immediately before cutting. Irrigation within 5 to 7 days of cutting raises the soil moisture content in the crown zone and increases the moisture content of the basal stem beyond what the plant’s natural physiology would produce at the same growth stage. This elevated stem moisture extends wilt time by 4 to 8 hours compared to paddocks where irrigation was timed correctly, compressing the baling window in summer cut conditions where time is the limiting resource.<\/p>\n

Post-Cut Re-Entry Timing<\/h3>\n

After cutting, irrigated lucerne paddocks should not receive irrigation for 3 to 5 days to allow cut-surface healing and prevent soil splash contamination of windrow material lying on the ground. Irrigation driven onto a freshly cut paddock with windrows on the ground raises windrow moisture back toward cutting-stage levels and can add 18 to 24 hours to the wilt period \u2014 a significant scheduling problem in the compressed multi-cut calendar of a MDB irrigated dairy operation.<\/p>\n<\/div>\n

Frequently Asked Questions From MDB Irrigated Dairy Operators<\/h2>\n
\nHow many bales can a solo operator make in a single cutting day on an irrigated MDB dairy?+<\/span><\/summary>\n
A solo operator running a 1.25 m round baler on tractor 1 and a separate wrapper on tractor 2 (alternating between the two machines) can achieve 180 to 280 bales in a 10-hour day in good MDB lucerne silage conditions. Two operators \u2014 one dedicated to baling, one to wrapping \u2014 can achieve 300 to 450 bales per day using the same two-machine parallel setup. Throughput drops to 120 to 180 bales per day on a single-operator combined baler-wrapper, reflecting the sequential nature of the integrated operation.<\/div>\n<\/details>\n
\nShould I buy a mower-conditioner or a plain disc mower for irrigated lucerne?+<\/span><\/summary>\n
Mower-conditioner without question for irrigated MDB lucerne silage. Conditioning (crimping or bruising the stem) is the mechanism that allows 18 to 24 hour wilt periods in the hot conditions of cuts 3 and 4 \u2014 non-conditioned lucerne in February requires 28 to 36 hours to wilt to 35% DM in the same ambient conditions, extending the wilt period past the safe window for field aerobic losses. The 9GQY-3.2 mower-conditioner is specified for the stem diameters and plant density typical of MDB irrigated lucerne production.<\/div>\n<\/details>\n
\nHow much silage film does a 5-cut irrigated dairy operation use per season?+<\/span><\/summary>\n
An irrigated dairy operation making 2,000 bales per season at 6 layers per bale of 750 mm \u00d7 1,800 m film uses approximately 90 to 110 film rolls per season. At wholesale prices of AUD $85 to $110 per roll, annual film cost runs AUD $7,650 to $12,100. Pre-order the full season’s film requirement in July or August \u2014 film availability in MIA and Goulburn Valley regional supply chains tightens severely from October to December as spring baling demand peaks. Early ordering also locks in pre-season pricing that may be 8 to 12% below the in-season spot price from rural stores.<\/div>\n<\/details>\n
\nCan I run a 4-cut silage programme instead of 5 to reduce operational pressure?+<\/span><\/summary>\n
Yes \u2014 reducing from 5 to 4 cuts per season reduces operational pressure significantly and is a legitimate choice for smaller irrigated dairy operations or those without dedicated baling staff. The trade-off is approximately 15 to 20% reduction in total silage dry matter production per hectare per season. Whether the operational simplification outweighs the production reduction depends on whether your silage inventory is supply-constrained (making as much as possible matters) or demand-constrained (you have more silage than you can feed). Most 100+ cow MDB irrigated dairies are supply-constrained and benefit from the 5th cut.<\/div>\n<\/details>\n
\nWhat are the signs that my multi-cut silage fermentation is inconsistent between batches?+<\/span><\/summary>\n
The most reliable indicator of batch-to-batch fermentation inconsistency is milking performance variation correlated with the silage bales being opened from a particular cut. If your TMR composition is consistent but milk production drops by 1.0 to 1.5 litres per cow per day when you transition from one batch to another, test the current batch for pH, ammonia nitrogen, and dry matter against the previous batch. Consistent fermentation across 5 cuts requires consistent moisture at baling (within \u00b13% DM between cuts), consistent inoculant application, and consistent wrap quality \u2014 track all three through the season and investigate any batch where measured results diverge from the norm.<\/div>\n<\/details>\n<\/div>\n
