This story outlines the 2026 grassland restoration project on a 2,000-hectare cattle ranch in Argentina’s Río Negro region. Long-term drought, overgrazing, and wind erosion severely degraded 600 hectares of pasture, causing bare soil, frequent dust storms, and failed traditional manual reseeding. To reverse land degradation efficiently, ranch owner Diego Fernández adopted YG Machinery’s YG-6 hydroseeding sprayer after professional screening. Following a successful 50-hectare trial with rapid grass germination and high ground coverage, the equipment finished the full 600-hectare restoration in 60 working days. The project significantly boosted grass coverage and ranch carrying capacity, curbed soil erosion and dust storms, proving hydroseeding as an efficient, reliable solution for large-scale degraded pasture restoration.

Before 2026
The Problem: 600 Hectares of Grassland Disappearing
For years, the Fernández family had operated a 2,000-hectare cattle ranch in Río Negro, Argentina. However, prolonged drought, overgrazing, and wind erosion gradually damaged the pasture. Around 600 hectares across three paddocks had become severely degraded, with thin grass cover, exposed soil, and frequent dust storms. Traditional reseeding methods had also produced poor results because seeds were scattered on dry, compacted soil without enough moisture or protection. Diego Fernández needed a faster and more reliable way to restore large areas before the degradation spread further.

The Solution: Discovering Hydroseeding
At an agricultural trade show in Buenos Aires, Diego saw a hydroseeding demonstration and learned how seed, mulch, fertilizer, and water could be sprayed together onto the soil. The mulch helped retain moisture, protect seeds, and reduce erosion, while the high-pressure spray system allowed large areas to be treated much faster than manual broadcasting. After researching different manufacturers, Diego contacted YG Machinery. Based on the ranch size, terrain, and remote paddock locations, YG recommended the YG-6 hydroseeding sprayer, which has a 6 m³ tank and a spraying capacity of 700–2,000 m² per load.

The Test: 50 Hectares in Just Three Days
Diego first tested the YG-6 on a severely degraded 50-hectare paddock where native grass cover had fallen below 10%. The team prepared a slurry containing native grass seeds, wood fiber mulch, slow-release fertilizer, and tackifier. The YG-6 sprayed the mixture evenly across the bare soil, creating a consistent protective layer. The entire 50-hectare test area was completed in only three working days, compared with an estimated three weeks using manual broadcasting. Germination appeared within 10–14 days, and ground cover reached approximately 60% after four weeks and 75–80% after eight weeks.

The Full Restoration: 600 Hectares Recovered
Encouraged by the test results, Diego expanded the project to the remaining 550 hectares. The YG-6 completed the full 600-hectare restoration program in approximately 60 working days. Within four months, treated areas achieved around 70–85% ground cover. The restored grassland improved the ranch’s carrying capacity by an estimated 25–30%, while the stronger root system helped stabilize the soil and greatly reduce erosion. Dust storms from the treated paddocks also effectively stopped. The project demonstrated that hydroseeding could provide a practical way to restore large areas of degraded pasture within a single planting season.

What Diego Learned and Would Tell Other Ranch Operators
If you’re managing degraded grassland in a semi-arid environment and considering hydroseeding, here are Diego’s recommendations:
- Choose the right tank size for your property. The YG-6’s 6 m³ capacity was ideal for a 2,000-hectare ranch. Smaller operations might find the YG-4 sufficient. Very large properties or commercial revegetation contractors should consider the YG-8.
- Use native seed species. Diego worked with a local agronomist to select a grass seed blend adapted to Patagonian conditions. Native species establish more reliably and require less maintenance than introduced varieties.
- The mulch-to-seed ratio matters. Diego found that a slightly heavier mulch application (toward the upper end of the recommended range) provided better moisture retention during dry spells. The extra mulch cost was justified by the improved germination rate.
- Time the application carefully. Diego scheduled the hydroseeding for early spring, just before the typical rainy period. The combination of hydroseeding mulch protection and natural rainfall created ideal germination conditions.
- Allow a full growing season before grazing. Diego kept livestock out of the treated paddocks for the first four months. This gave the grass time to develop a strong root system before facing grazing pressure.
- The hose reach is a hidden advantage. The YG-6’s pipe head range of up to 70m horizontal meant the operator could spray from established tracks without driving onto fragile, newly seeded ground. This reduced soil compaction and protected the seedbed during the critical establishment phase.
