I sometimes get asked why we print tips, or lon- ger articles on the more technical sides of gro- wing, on subjects ‘we’ve often read about before’. A good example is hygiene. And pests like mushroom flies – and prevention tactics to con- trol them – regularly land on these pages. Or damage caused by fingernails and how to prevent it. In our ‘Out and about’ item, or articles like the Rwanda report in this edition, we also regularly devote space to situations that have long been banished to the past on modern mushroom com- panies. If you routinely produce 8000 tons of phase III a week, there’s not much to be learned from reading about labourers weighing straw on a wooden pole. But if you feel the content is some- times generated by the repeat button, note the following. Firstly, as the wise saying goes, ‘repeti- tion is the mother of perfection’. Almost every punnet on display in the supermarket has some mushrooms with nail traces, and the financial consequences of insect damage still amount to millions. Even though they already know the pro- cedures and guidelines, many readers still like a reminder of how things should be done or done more effectively. Secondly, as the scale of opera- tions continues to increase, growers sometimes risk losing ‘contact’ with the basic principles of, for instance, straw and composting, because they have so many other tasks and distractions. And, not all our readership operates at the same level of skill and experience. Some were not even born when our first tips were published. Add to that the challenge of recruiting (picking) staff these days. If you find staff, they only stay a short while and often have limited knowledge. What seems normal routine to you could be quite an eye ope- ner for them. Technical developments in growing and composting are on-going, and our contribu- ting authors include these new advances and insights in their advice, tips and reports. And finally, our older audience likes to read about ‘how we did things back in the day’. Whatever category of reader you are, enjoy this new edition of Mushroom Business.
The next one will be an extra thick - and as good as new - jubilee edition.
