Casing soils for mushroom production

Klasmann-Deilmann and Dut­ch Fores­try Admi­nis­tra­ti­on sign contract

Klasmann-Deilmann Bene­lux has secu­red long-term dis­tri­bu­ti­on rights for so-cal­led casing soil * used in the pro­duc­tion of mushrooms. „This will streng­t­hen our posi­ti­on in an important seg­ment of the food indus­try,” says Moritz Böcking, Mana­ging Direc­tor of the Klasmann-Deilmann Group. Signi­fi­cant quan­ti­ties of the­se raw mate­ri­als should be avail­ab­le by the turn of the year 2020/2021 at the latest. The con­trac­tu­al part­ner in the pro­ject, which will run for several years, is the Dut­ch com­pa­ny Ener­gie­hout B.V., a sub­si­dia­ry of the Sta­te Fores­try Administration.

Sin­ce 2019, the Dut­ch Fores­try Board Staats­bos­be­heer has been pre­pa­ring a natu­re deve­lo­p­ment pro­ject near Bre­da. In order to crea­te addi­tio­nal floo­ding are­as for the rivers on the bor­der with Bel­gi­um, the banks near Wei­me­ren are to be lowe­red and a deeper river bed crea­ted. The­se mea­su­res are expec­ted to have posi­ti­ve effects on regio­nal biodiversity.

A look into the future of the Wei­me­ren land­s­cape deve­lo­p­ment project.

The deve­lo­p­ment of the 200ha floo­d­p­lain will neces­si­ta­te the remo­val of low­land peat, which is of inte­rest to the mushroom indus­try. „We have tes­ted the raw mate­ri­al for its sui­ta­bi­li­ty as casing soil,” reports Ted Vol­leb­regt, Mana­ging Direc­tor of Klasmann-Deilmann Bene­lux. „A balan­ced mix­tu­re with Ger­man black peat results in an excel­lent pro­duct for mushroom pro­duc­tion.” Unli­ke com­pa­ra­ble raw mate­ri­als, Dut­ch low­land peat requi­res neit­her frost nor dry­ing. Nevertheless, qua­li­ty assuran­ce is of gre­at impor­t­ance. „To ensu­re mar­ke­ting and cus­to­mer satis­fac­tion, the raw mate­ri­al has been cer­ti­fied accord­ing to RHP stan­dards, which inclu­de com­pre­hen­si­ve and strict qua­li­ty cri­te­ria.” Fur­ther­mo­re, spe­ci­fi­ca­ti­ons for the pro­ces­sing of the raw mate­ri­al are clo­se­ly coor­di­na­ted with the com­mis­sio­ned ser­vice com­pa­ny Den Breejen.

Our substrates and casing soils are indis­pensable in the inter­na­tio­nal food indus­try. We sup­ply just under half of our pro­ducts to nur­se­ries that cul­ti­va­te fruit, vege­ta­bles, herbs and edi­ble mushrooms. Healt­hy food is of cen­tral impor­t­ance for our com­pa­ny,” exp­lains Moritz Böcking. „We are very plea­sed to be able to use local raw mate­ri­als for the food indus­try and to con­tri­bu­te to an important envi­ron­men­tal pro­tec­tion pro­ject in the Netherlands”.

* So-cal­led casing soils are among the most important resour­ces in mushroom pro­duc­tion. They con­sist main­ly of high­ly decom­po­sed peat raw mate­ri­al. For the pro­duc­tion of mushrooms, spe­cial com­posts are first laid out on lar­ge are­as in the farms, con­sis­ting of straw and hor­se manu­re, for examp­le, and are ino­cu­la­ted with mushrooms. A lay­er of the casing soil about seven cen­ti­me­tres thick is spread out over the com­post and the mushroom pene­tra­tes it. The frui­t­ing body of the edi­ble mushroom final­ly forms on the surface.
