Have seen some big old standard apple trees that met the criterion of a shade tree - had one in the middle of the hayfield on the farm I … Tagasaste has more productive potential than lucerne (Oates and Clarke 1987). Table 1. As tagasaste roots more deeply than lucerne, it may have a greater tolerance to drought. Many can be propagated from seed, or from cuttings, a process which minimises establishment costs considerably (Felker 1978). periods of high environmental stress. Their foliage also generally has Deciduous, providing foliage in spring and summer.

Logan & J.E. by their exploitation in wetter areas for protein-rich browse On maturity, the trees provide six or seven tonnes of high protein pods per hectare in a year (Felker 1981). Many of the trees that are planted as sources of fodder make ideal windbreaks; they modify the microclimates beneath their canopies; they reduce water loss from the soil, and reduce evaporation from nearby fields, and from dams; they reduce soil erosion; they lower the temperatures the animals must endure. Trees and shrubs have long been considered in those areas with a pronounced dry season. Prefers hot, dry climate, but is suited to wide variety of climates. Yemane (Gmelina arborea), Dead finish (Albizia basaltica), Marcar, N. (Ed) (1995). Khosla, P.K., Puri, S. and Khurana, D.K., eds.

This compared with less than one tonne per hectare from annual pasture. In Agroforestry Systems : a new challenge. Lowry believes Australia, it has sometimes been claimed, has an efficient agricultural system. detrimental factors that reduce the utilization of protein not are often inaccessible to grazing animals, and increased labour Fleming’s Top10 Trees makes choosing the right tree easy. 1985, 'Fodder Tree Research at Whatawhata Hill Country Research Station', in Fodder Trees - a summary of current research in New Zealand, eds L.A. Logan & J.E. Agroforestry is the use of trees that give high feed yields all year round, every year, even where grasses cannot grow. The importance of this industry to Australia lies in its contribution to the productivity of other agricultural sectors. Nevertheless saltbushes can be grown over a wide range of climatic conditions, and on good soils. Honey locust: Gleditsia triacanthos: Grown for high yield of pods. Again, do as you wish, but I won't be descriminating against oak trees in our pastures. planting millions of trees across the developing world since 1989. The role of woody perennials in animal agroforestry. Is there a limit, then, to where trees for fodder can be grown?

Evergreen trees are simply the most popular landscape trees in Australia including selections of Acmena, Elaeocarpus, Ficus, Magnolia, Syzygium, Tristaniopsis and Waterhousea. In recent years, this traditional use has been complemented Trees need to be well spaced for best growth. Valuable in soil stabilisation work (Duke 1981; Felker & Bandurski 1979). It involves the use of fodder trees and shrubs - trees that are permanent, and which will replace annual grasses; trees which will provide their own nitrogenous fertilisers; trees which will extend their roots deep beneath the ground to the water table. But then, some pasture improvement programs can take up to fifteen years to achieve! Many of the trees and shrubs that are suitable for fodder are far less affected by drought (Douglas & Hart 1978). : lesser-known species for fuelwood and agroforestry. In Peru, thousands of hectares of another species of prosopis, Prosopis juliflora, have been cultivated for livestock. Best shelter picks: Cryptomeria, casuarina, willow, pine, eucalyptus, feijoa, macadamia, pittosporum and other native trees. Fast growing and long-lived. Many of these are dry country species able to endure drought and saline soils, such as the chenopods (saltbush and bluebush). There are just under 15 million sheep located primarily in the agricultural region, producing high quality meat and wool for world markets. Douglas, J.S.

All are also considered to be good timber trees, Some fodder species also have timber potential. Yield about 15 tonnes dry matter per hectare per year on one-third tree cover to two-thirds grass cover; recovers quickly from complete defoliation and heavy grazing. Foliage contains about 23% protein (Davies 1982; Davies 1985; Rumball & Cooper 1985). Albizia saman) (Lake 1997). Propagated from seeds or from suckers. adversely affect digestibility of dry matter. Each year, soils become less productive. Most of the trees (Lefroy et al. Under these circumstances the value of trees and shrubs is considerable Canberra, ACIAR. (Abel et al. The following 6.

Because tagasaste can tap the water deep in the soil, the relative yield from tagasaste compared with pasture will generally be higher under low rainfall conditions. Ideal for soil stabilisation work (Batten 1985; Douglas & Hart 1978; McLeod 1985). Anyone can find an argument not to do something. How long To plant a larger area requires a livestock trading enter- prise that can take full advantage of an out-of-season feed supply. tree introduction. Trees and shrubs have several disadvantages as sources of feed. The high protein content of its foliage is excellent for animal fodder and at the same time improving soil fertility. It has been left on the web due to its apparent Adelgids and honey fungus can be a problem for these trees. Toxicity : The harmful effects of feeding a particular latent internal damage may be caused (Negi 1986). Are large profits made from the land? above livestock reach, that are capable of severe lopping during Table 2. to cause a low palatability of the foliage. Oates and Clarke (1987) suggest that early settlers found that lopping the scrub for emergency feed was often all that kept them going during especially dry seasons. In trials in Western Australia, in deep sand and with 530 mm rainfall, tagasaste planted at 900 trees per hectare produced three tonnes of dry matter per hectare. MacFarlane, M.D. Acacias and casuarinas too are suitable for supplementary fodder (Oates & Clarke 1987). ...there were also many other lofty cultivated trees which provided unlimited fodder for beasts. Has the New Zealand experience with tagasaste been a complete disappointment to the farmers who have taken the initiative and planted such trees? and their leaves, etc. Design compounds (Lefroy et al. most suited for the landowner and the local conditions.

Holes about a metre or so across, and a couple of metres deep, are excavated through the salt crust for the trees. Fodder trees are less affected Red Cedar. The elm's large volume of canopy contains much needed proteins, carbohydrates and minerals sought by livestock. Tagasaste, for example, although high in protein, is low in carbohydrate (Oates and Clarke 1987). Some contain toxic substances or thorns that make management 1992). (Samanea saman syn.

Kurrajong is regarded in Australia as one of that country’s most valuable fodder trees. Tree Care Extension Officers (1996). Rural Prefers well drained soil, but generally quiet hardy. Yields of five to seven tonnes dry matter per hectare per year on first cutting, second browsing should double this. Can be grazed within their first two or three years (Batten 1985). Is the problem associated with annual periods Tall shrubs, prolific growth in warm regions; sensitive to frosts. Dual purpose trees for agroforestry. which Lowry has identified with potential for this dual purpose Planting trees just outside the fence around the pasture boundary is usually adequate. Good fodder trees should produce large crowns 1981, Handbook of Legumes of World Economic Importance, Plenum Press, New York. New Zealand scientists have researched the potential, and farmers there have adopted one or more of the varieties of trees or shrubs that are suitable for that country, for example tagasaste, saltbush and willow (MacFarlane 1985; Bell 1985; Sheppard 1985; Radcliffe 1985). These trees are naturally symmetrical and are best left to develop naturally, untrimmed. they often have lower energy value than herbaceous plants due does the period last? In Peru, thousands of hectares of another species of prosopis. Digestibility : Although sometimes higher in protein, They Drought resistant, these grow in low rainfall areas, although an even rainfall of 100 mm per month provides best growth. to make use of dry season pastures (Abel et al.

Propagated from seeds or from suckers. Susceptible to more than 3-4 degrees C of frost. erosion. Agroforestry Systems 2, 131-163. Many contain tannins and other astringent compounds, which In Tolerant of frosts. careful consideration. But tagasaste, for example, is grown from seed (Race 1993). This tree is a legume, but it is not known to fix nitrogen, although this is highly likely. Pods are consumed - seeds contain 21% protein; yield can be 400 kgs per tree or 50 tonnes of pods per hectare per year (Douglas & Hart 1978; Duke 1981). In England and parts of northern Europe, elms were used as a source of fodder until the mid-1800s. Brachychiton populneum (syn b. diversifolia) – Kurrajong.

Trees have often been included in farm planning for amenity Looking at the overseas experience, it appears there is great potential in Australia for the use of fodder trees for livestock production. Legumes, growing well in impoverished soils. Trees for the Future Founder, Dave Deppner, visiting the livestock of a smallholder farmer in Honduras. Hill tops that cannot be ploughed or planted to grasses, can carry trees (Douglas & Hart 1978; Lamb 1979). Prefers well-drained, deep soils, but quality is immaterial. In that part of Chile, Prosopis tamarugo trees have been planted as a sole source of fodder for livestock, and these trees provide about six tonnes of leaves and pods per hectare each year. Sheppard, J.S. Yields not only have to be maintained, they should, ideally, be increased, to provide food for our increasing population (Douglas & Hart 1978). Radcliffe, Crop Research Division, Department of Scientific and Industrial Research, Christchurch NZ. Forest Products][Minor For best harvesting, you'd probably need to mow fairly short underneath the trees just before nut drop. or better, for individual site conditions. Race, D. 1993, Agroforestry - trees for productive farming, Department of Conservation and Natural resources, Melbourne, Vic. The feed yield from fodder trees - even grown under adverse conditions and in poor soils - can match, and often exceed, that from pastures grown under good conditions (Lamb 1979). They’re an example for the rest of us, really.
