I strongly believe that with good management in the right environment, livestock can complement a cropping enterprise in a number of ways and vice versa... The Environment Conventional cropping systems in the Central USA have low levels of biological diversity and rely heavily on synthetic fertilisers and herbicides... An experiment run over 10 years by Texas Tech University USA, has shown that an integrated crop/forage/livestock system compared with a cotton monoculture has decreased nitrogen use by 40% and lowered irrigation water use by 25% whilst maintaining similar profitability between the two systems...

A match made in canola heaven.. In the first series we look at how growers and researchers teamed up to turn canola into one of the mainstays of today's cropping system... "Over a decade of experiments, our team demonstrated the rotational benefit of canola, and growers saw that while it could be expensive and tricky to grow, it was profitable if you took a two-year view," he says...

Western Australian research suggests the inclusion of fallow in the crop sequence can be a productive option, boosting the yields of subsequent crops and helping to control annual ryegrass... Working with seven grower groups in the southern region, the project aims to examine the productivity and financial implications of growing pulse or brassica crops in various combinations and under different management in a cereal-based cropping system... Farmers, researchers and agronomists are going head-to-head in a challenge to see who can make the most money from growing pulses in the crop sequence..

Crop sequences will continue to be an important part of profitable and sustainable cropping systems in WA. Research conducted in this project showed the potential for substantial improvements in the profitability of crop rotations if break crops were used more widely... The new insights about the value of break crops in profitable crop rotations and the revised assumptions to the MIDAS model have been used to improve new models being developed by the CSIRO and DAFWA (the Land Use Sequence Optimiser (LUSO) and Leap economic models, respectively)... For example, there had been no research into the break crop effects of oaten hay in WA and one of the most common rotations on WA farms - lupin/wheat/canola/barley - had not been examined...

Break crops can help increase the returns from future wheat crops... Break crops are profitable when the expected increase in return from future wheat crops exceeds the opportunity cost of growing a break crop instead of a wheat crop... We used an economic model to capture the costs and benefits of including a break crop in the rotation...
