Legume biomass and seed yield were best for fababean, fieldpea, and chickpea. Potential for use of legumes for hay or silage. Barley yield after legumes was comparable to barley after fallow, and better than barley after barley or wheat. N contributions to the cropping system, except for field bean, were greater for legumes than for fallow. High N fertility levels from legume N plus fertilizer N resulted in premature soil moisture depletion. Optimum rotation performance will depend on balancing nitrogen fertility with expected available moisture.

Investigated yield and N response in barley and wheat, 1 and 2 years after pulse crops of fababean, pea, and lentil. Overall yields were higher on fababean and field pea residues than lentils. Soil tests could not attribute yield differences among crop residues to differences in soil N levels at time of seeding. Nitrogen fertilizer equivalents for barley were 105, 85, and 50 lb N/ac for fababean, peas, and lentils. Legume residues influenced barley grain quality. In the second year following pulses, the dry matter yield, grain yield, and N uptake of wheat was 15% higher than in the continuous cereal sequence. Analysis of 3 completed rotation cycles showed that cropping sequences that included pulses were considerably more productive than the continuous cereal sequence in terms of net energy production and economic gross margin to cash costs. Field peas were the most effective first-year crop in terms of net energy production.

Montana researchers examined the performance of several grain legumes (dry pea, chickpea, lentil) and their effect on a subsequent barley crop. Dry pea production was the highest. A subsequent barley crop rsponded to added N fertilizer at three out of six sites. Barley yields following legumes were generally equal to or greater than yields following fallow. The annual legumes contributed to soil N and reduced the fertilizer N needed to reach maximum yield by 40-55 lb N/ac when compared to recrop barley. This translated into savings of $10-14/ac for fertilizer N.

There is now clear consensus among most rural producers, scientists, bureaucrats and politicians that many of Australia's farming systems are unsustainable, using present methods. While broadacre agriculture has been considered by some to be technically sustainable, economic pressure placed on farmers due to declining terms of trade is indirectly responsible for the instability of many farming systems. The current awareness stems from irrefutable evidence that our crop and animal production methods have resulted in both dramatcic and insidious forms of land degradation. However, the sustainability of our farming systems has been questioned for some time, and at least three symposia dating from 1983 have dealt largely or wholly with this issue. Sustainable agriculture is now in vogue, so much so that one rural magazine now carries the slogan "Striving for Sustainable Agriculture" as its banner. And Australia now has a National Association for Sustainable Agriculture (NASAA). It should then be easy to define a sustainable farming system, particularly if the definition is restricted to cropping.
