Russian Grass Protein Levels: 25-35%, typically double that of baled lucerne (16-18% protein), scientifically tested. When boosted with nitrogen, up to 35% protein. Best protein levels at about ankle to knee height, about 2 – 4.5 months.
What you must learn:
Case Study 4: Barkley East
• It takes a while to establish unless you boost it with soil fertility/manure. It first needs to grow a massive taproot sinker root system before it becomes fully commercial.
• The first 6 months is best set aside for establishment and seed set.
• It doesn’t like temperatures above 35 degrees and require lots of water.
• You must guard against premature grazing at 3 months with cattle, they can rip it out root and all. Sheep can graze it at 3 months.
• It seems expensive at R1 per square meter, until you work it out over 30-60 years.
• The ecological footslope wetland niche that it thrives in is not easy to plant always and this could result in a longer period of establishment. Often we need to compromise in real life and accept summer grass competition and a longer establishment period in less than ideal conditions. The critical issue is that for every 1 kg of Breeder Seed we do establish we get 100 kg of seed drop as a rule of thumb.
• Once established it mines the full soil profile for water and nutrients and recycle these into very high protein, double the nutritional density of lucerne.
• It grows in severe cold right through winter.
• It can handle extreme waterlogging and flood events and loves water seepage and heavy nutrient concentrations.
• It is a swamp grass ideal for footslope, toeslope floodplainland.
• It doesn’t burn but remains green.
• It makes a lot of F1 seed, which live for 10 years per cycle and provides 40(-80%) faster metabolic performance compared to commercial seed; or the breeder seed parental lines.
• It can filter out huge amounts of nutrients from water, manure and effluent.
• You cannot kill it with nitrogen burn in normal conditions. This means that a hill planted to clover will wash nitrogen down into the Russian Grass at the footslope or toeslope where ultra high carrying (x 5 to x 10) capacities can be achieved due to the water and nutrients from the mountain above it.
• Profesionals with sound judgement and clear eyes making investments.
• Long term strategic thinking customers able to define risk.
• Technically sophisticated able to manage establishment risk.
• Protein focused and not picture focused.
• Long term planners willing to take short term pain in wetlands.
• Willing to master new skills for long term gains.
• Independent pioneer thinkers not given to convention.
• People willing to take short term risks and costs for long term perennial benefits that is scientifically possible and commercially desirable. • People able to see not only what is under the soil, but also what is above the soil, as well as what could be on the footslope of hills and in the toeslope vlei and who work out a way to achieve it systematically. • People who are paradigm and profit shifters who do their homework. • People always learning, always refining and always improving. • People who march to the beat of their own drum. • We focus on projects. Our customers are people building feedlots over many seasons. They start small and do it very big and fill up every ecological niche. We focus on best practise and join forces with others in similar ecological conditions and tap the collective experience and wisdom based on the last 10 years worth of establishment lessons.
1. 1 hectare established with 5 kg of Breeder Seed has the seed production potential of 100-300 kg of annual F1 seed; enough to establish 600 000-700 000 plants on a permanent basis with permanent young growth of 25-31.8%-35% protein.
2. The higher quality of F1 Hybrids increases the plant vigour and individual plant hardiness/fitness by 40%-80%, enabling extensive use in the temperate and very cold summer rainfall and cold grassland areas of South Africa such as the Eastern and Northern Free State, Eastern Cape, Western Cape, Mpumalanga and KZN. Cold tolerances of -20 Degrees Celcius become possible, with commercial feedlot performance from about 800mm+ per year/ha upwards, rainfall included, all the way to 4000mm. Every 100mm of water available in the soil profile up to 1.8m depth is worth about 1 ton of edible material, as a general rule of thumb. If you have steep mountain slopes and foothills in a valley with 1000mm of rain, you typically get 10 tons of biomass from the rainfall, and if you have subsoil seepage of another 1000-2000mm throughout the year, you get another 10-20 tons for a combined 30 tons of edible material ha year at 25-31.8% protein.
3. If you have legumes on the upland area or lots of feedlot manure the protein level can be boosted to 35%. We use stud earthworms in big feedlot soils to incorporate industrial amounts of manure. The combination of water and very high fertilisation/manuring make it possible in some ecological niche areas to raise carrying capacity from 1 LSU per Ha to 5-10 LSU, by basically stacking the soil fertility nitrogen run off/manure and moisture seepage of 5-10 ha unto 1 ha of footslope/toeslope or floodplane.
4. The advantage is that you don’t need to irrigate the Green Mamba once established as the taproot self-irrigates the plant from subsoil moisture seeping down on the bedrock due to gravity. The ideal place for Green Mamba is areas with about 5cm of soil over a permanently wet or moist subsoil or clay. During establishment when small it must be above water. When it is hand height it can handle more and more water, but generally a layer of dry soil is required.
5. Plant establishment rates of 70-80% from F1 Hybrid seeds lowers establishment costs compared to vegetative methods by 90%, due to the high individual plant fitness derived from hardy F1 plant genetics. It is possible to spread seed on a broad acre basis in a vlei area; and for every 1 kg of Breeder Seed about 100 kg of Commercial quality F1 seed is produced annually filling in the
wetland/vlei/waterlogged area until a continuously green high protein frost resistant feedlot pasture establishes. It may take 1-3 seasons to completely fill in the available open spaces between the mother plants, depending on management, season and soil conditions and soil fertility. In very wet years it may be too wet for seed dropping to establish and in other drought years it may be to dry. Give it time, the Breeder Seed lives 6-10 years and will fill in F1 plants over time.
6. Large volumes of annual commercial seed with continuous replanting cost and high effort and fuel cost are no longer required for a lush stand, and much larger areas can be established on a broad acre scale due to self seeding of F1’s. We typically seam foothill/waterlogged and fountain/vlei areas with a pioneer Breeder Seed population and increase the F1 plant population density and nutritional density over time with natural seed drop. Commercial production happens from year 2 onwards when the self-irrigating taproot has established. If we no-till with low pioneer stand establishment rates and lots of heavy vlei grass competition godo thick establishment takes 2-3 years in unfavourable conditions.
7. A 1- hectare seed orchard can produce 100-300 kg of F1 hybrid seed annually, providing enough seed to establish roughly 600 000-700 000 plants per ha, of 25-31.8% protein. For commercial success we only need 1 kg of Breeder Seed plants to establish successfully on 1 ha of 10 000 sq/m2.
8. In areas where the habitat and nutrition is sub-optimal in the topsoil, establishment success is still possible due to hardy genetics for multiple generations making the plant more persistent. It slowly dominates due to seed drop. The commercial result is successful commercial establishment from breeder seed at affordable rates, over the medium to long term.
9. We will now make use of pictures and historic insights to further explain the genus Phalaris genetics used in our inter and intraspecific hybrids from a very wide genetic base.
