Energy and yield

Filing-weight-mushroomcompost

Production costs are rising sharply. Faced with the high cost of compost and higher energy costs, how can you produce more mushrooms per ton of compost using less energy? This blog explains one of the options.

Bacterial blotch

Bacterial blotch mushrooms

Bacteria are present everywhere, all the time – but do not cause bacterial blotch. What does cause bacterial blotch is too many bacteria. A bacterial blotch infection of mushrooms is caused by favourable growth conditions for bacteria.   How can you prevent bacterial blotch? By preventing the conditions in which bacteria can grow rapidly. I […]

Does a higher filling weight give better quality?

Mushroom compost phase III

The filling weight, i.e. the number of kilos of compost per square metre, should be between 80-95 kg/m2. The general trend is the more compost, the better the mushroom quality. But is that right? Mushroom growing is all about the difference between air temperature and compost temperature, referred to by growers as activity. Activity is […]

Dry bubble disease (Verticillium)

Dry bubble Verticillium

Dry bubble disease may cause a lot of problems because the spores spread quickly. It’s essential to identify and remove the first affected mushrooms to prevent an outbreak of the disease throughout your entire nursery. So how do you remove the first infected mushrooms? Spread by spores Dry bubble disease is spread by spores. The […]

Which factors determine the pH value?

ph waarde meten champions

My previous blog described what the pH should do during the composting process. This blog examines the role of the raw materials, such as ammonium sulphate, gypsum and water. Ammonium sulphate, (NH4)2SO2 During indoor composting, NH3 is removed from the air by a reaction of the air to sulphuric acid, H2SO4. The by-product resulting from […]

Too much mycelium

Too much mycelium - mushroom growth

On many farms I see lots of problems with quality and particularly  production in the second and third flushes. This immediately prompts a close examination of the compost, although the problem has developed at the start of cultivation in the casing soil. Casing soil acts as a water buffer. That is nothing new.  But after […]

Watering

watering - mushroom growth

A new watering system has been in use for some years now. It is a static system that incorporates pipes and nozzles in the beds. With conventional watering systems, a spray lorry moved along the beds. This blog explains the advantages and disadvantages of the static system. How the static system works The static system […]

Sealed growing rooms and tunnels

sealed rooms mushroom growing

Well-sealed growing rooms are essential in order to exclude phorids and sciarids flies! Using chemical or biological control agents makes no sense at all if there are all manner of entry and exit routes still open to phorids and sciarids. If a room or tunnel is well and truly sealed, then you won’t even need […]

Recovering Period

recovering period - mushroom growth

Mycelium has to grow toward the surface where it develops pinheads. How do you achieve this? By not using the cooling! Common mistakes: You set the computer phase from mycelium growth to recovery period. For example, you set the air temperature to a minimum of 19oC. Heating quickly helps reach this temperature. The RH is set […]

Pre-wett

pre wett- mushroom growth

Straw determines the structure and the nutrient value of compost. New straw is harder, which is why the pre-wet period is crucially important for good production. Exciting: the first new straw Last year the straw produced in Europe was bad quality. For this reason many composters are quickly switching over to using the new season’s […]
