1 ALOSCA™ granular inoculant New inoculation technology for grain and pasture legumes Angelo Loi & Steve Carr (Bayclassic)

2 Crop and pasture legumes add enormous value to farming primarily through their : -Ability to fix atmospheric nitrogen -Weed control -Wool and meat production.

3 Root nodule bacteria NITROGEN

5 Traditional inoculation

6 Nodulation failure

7 Rhizobium effectiveness Uninoculated Inoculated

8 Casbah (biserrula) Thanks to the Centre for Rhizobium Studies we have some of the best strains in the world

9 Trifolium incarnatum cv Caprera …and we can successfully grow the new pasture species recently developed in WA

10 Grain legumes

11 Old technology (peat based) Peat inoculants must be stored and transported at 4-6 O C Best when inoculated onto seed and then sown immediately into moist soil Rhizobia die rapidly when exposed to high heat and when exposed to dry soils in southern Australia (>90% within 24hours) Rhizobia have sub-optimal performance when mixed with certain seed-applied fertilisers insecticides and fungicides

12 Why do we need ALOSCA to inoculate our pasture legumes Easy to do (mixing one bag of ALOSCA and one of seed) Reduce the risk of decreased rhizobium viability under stressful condition (eg. sowing in suboptimal conditions or dry autumn conditions) Be ready to sow when conditions are right Undersowing and dry-sowing are possible due the high viability of the rhizobium in the granules (over one year in the soil)

13 - Often a compromise between disease control (seed applied fungicides) and effective N fixation (conventional inoculation) - Rhizobia die when inoculated seed is sown into dry soil & this cause a delay in nodulation- compromise yield Grain legumes

14 Liquid inoculant Liquid-based inoculants generally have a shelf-life of less than six months Logistics of delivery on a large scale Liquid-based inculants have a limited inoculum delivery potential of several thousand cells per seed

15 - Western Australian company - International patent - Special clay combined to a novel technique

16 Improving inoculant technology ALOSCA PEAT Uninoculated ALOSCAPeat

17 Faba beans Nodulation score at 8 weeks for Faba beans sown with ALOSCA at Mullewa and Nyabing (average of both sites) Howieson et al 2004.

18 Pea rows at Nyabing

19 What happen when condition start to get suboptimal? Peat and Liquid technology work very well under optimal moisture and temperature soil condition

20 Summer temperatures on soil surface are very high

21 Uninoculated Fresh peat ALOSCA 6 weeks at high temperature

22 ‘ALOSCA’ dry clay inoculant provides the opportunity to sow legumes dry ALOSCA granules sown at 10 kg/ha with faba beans produced better nodulation than normal practice Nodule score on Faba beans at 10 weeks

23 ALOSCA Traditional Whittington’s farm (East Brookton) Dry autumn conditions

24 Max Hawley (Pingrup): Faba beans seed production ALOSCA Sandy: 165 % Clay: 114 % Conventional Sandy: 130% Clay: 102 % Uninoculated Sandy: 100 % Clay: 100 %

25 ALOSCA SEED Flexibility – capacity to mix ALOSCA with both seed and fertiliser Same storage No refrigeration needed

26 Burr Medic (4.7 pH) Untreated No nodules ALOSCA Top dressed 10 kg/ha ALOSCA Drilled 5 cm - 10 kg/ha Remedial option for poorly nodulated pastures

27 Introducing improved strains in old pasture stands of sub-clover

28 ALOSCA has been tested in WA (2003-4) “Ballard Seed” evaluated ALOSCA at 12 demo sites in 2004

29 Up to 6 t DM 1 t of seed T. formosum cv Portolu inoculated with ALOSCA Paish & Wilson (Badgingarra)

30 Biserrula (Casbah) inoculated with ALOSCA granules at Tincurrin (Ballard Seed)

31 Yelbeni (yellow serradella) inoculated with ALOSCA granules at Hagboon’s farm

32 Summary ALOSCA: viable alternative to conventional inoculation Granules remain viable in the soils for extended periods in soils subject to wetting and drying cycles (ie false break) Research indicates equivalent nodulation (to conventional ) under optimal conditions- but SUPERIOR under adverse conditions Easy to handle

33 Summary cont. Option for seed applied insecticides (important for small seeded pastures) Current indications are that up to 1000 times the number of cells in ALOSCA are alive at sowing compared with conventional inoculation Enables effective nodulation under poor or dry sown conditions ALOSCA is compatible with seed applied fungicides

41 Why pastures in the rotation? Nitrogen Weed control More sheep per ha

42 After: Santorini (yellow serradella) pH mm DM = 11t & >3t pods Potential water use over 500 mm 15 sheep/ha Trees to be planted Before pH mm Poor sub-clover pasture 4 sheep /ha 2t of wheat (80-100kg of Urea)

43 Trees to be planted 2004 Wheat after serradella: a) 50Kg “Maps”2.74 t/ha11.4% (prot) b) 50Kg “Maps” + 30Kg Urea2.50 t/ha10.7% (prot) Tot. 10t DM (tops and roots) 3.5% = Tot. N org = 350Kg 350Kg of org. N = 700kg of Urea 30% of this N will be available in the next year= 210Kg Urea (equiv.)

44 Biserrula (Badgingarra) 2004 Wheat after biserrula: a)Agstar 100Kg + Urea 40Kg5.7 t/ha b)Agstar 100Kg + Urea 110Kg + NS t/ha

45 Undersowing Sowing Hard French serradella pods Wheat Fertilizer ALOSCA granules (S) Wheat Established pasture First year Second year Hardseed breakdown of the pasture seed Establishing cheap pastures

46 Grower survey Farmers asked to list for 2004 –areas sown to pasture –pasture legume varieties used 156 responses Mainly wheatbelt farmers Total farm area in survey: 572,852 ha 87% of respondents sowed new pastures in 2004 Area sown to new pastures: 64,470 ha –Average of 26% of total area in pasture

50 Grower survey  There is a strong interest in pasture improvement in Western Australia;  An estimated total area of 1.3 mill ha of wheatbelt and mixed farming areas was sown to pastures in 2004;  Over 50% of all pasture legumes sown in 2004 have been released since 1996 and are derived from the WA NAPLIP/CLIMA programs;  Over 55% of species sown in 2004 were not the traditional species (subterranean clovers and medics)
