Tuairisgeul

Is e aon aonad 1 unnsa.
Bidh aon aonad a’ làimhseachadh 2–4 pileachan.

Sealladh farsaing:

Dè a nì e:
A’ cur spionnadh air cruachan compost agus gan cuideachadh le bhith a’ briseadh sìos nas luaithe agus nas coileanta. Gu sònraichte feumail nuair nach eil stuthan compost freagarrach no nuair a tha an aimsir dùbhlanach.

Mar a chleachdas tu:
Measgaich 2 spàin-bùird de thoisiche tioram ann an 1 galan de dh’uisge blàth. Leig leis suidhe airson 6–12 uairean. Craith thairis air sreathan de chruachan compost.

Tàthchuid:
Measgachadh coipeadh tioram a’ gabhail a-steach BD 500 caolaichte, BD 502–507, air a choipeadh fiadhaich (gun beirm no bacteria cultarach air an cur ris), mòran eileamaidean buannachdail eile

Mion-fhiosrachadh mun toradh:

’S e reasabaidh shònraichte a th’ ann an Tòiseachadair Compost Pfeiffer™ ​​a chaidh a leasachadh leis an Dr. Ehrenfried Pfeiffer gus obrachaidhean compostaidh a leasachadh.

Am measg ar bathar reic as mòr-chòrdte, chaidh toraidhean Pfeiffer™ ​​a chruthachadh anns na 1940an leis an Dr. Ehrenfried Pfeiffer leis an amas bith-dhinimigeach a dhèanamh nas ruigsinniche do ghàirnealairean dachaigh, tuathanaich àbhaisteach, agus luchd-compostaidh. Is ann le JPI a-mhàin a tha na foirmlean seilbhe seo. Tha Tòiseachadh Compost Bith-dhinimigeach (BD) Pfeiffer™ ​​a’ toirt a-steach na h-ullachaidhean compost gu lèir (BD #502-507), Aoileach Adharc BD (#500) a bharrachd air measgachadh dùmhail de shreathan àiteach de bacteria ùir buannachdail, enzyman, fungasan, agus factaran brosnachaidh fàs planntrais a bhios ag àrdachadh iomadachadh meanbh-fhàs-bheairtean agus mar thoradh air sin bidh lobhadh stuthan nas luaithe, seasmhachd naitridean, agus cruth-atharrachadh gu humus colloidal.

Tha Tòiseadair Compost Pfeiffer™ ​​a’ tabhann buannachdan an t-Seata Iomlan de Ullachaidhean Compost Bith-dhineamach a bharrachd air raon farsaing de chultaran agus einsìmean meanbh-bhitheòlasach eadar-mheasgte.

Co-dhèanamh Tòiseachaidh Compost BD Pfeiffer™ ​​Tha an Tòiseachaidh Compost cumhachdach seo a’ gabhail a-steach na h-ullachaidhean àiteachais bith-dhineamach BD #500, #502, #503, #504, #505, #506, agus #507, a bheir an toradh seo cho èifeachdach sa tha e. Tha measgachadh dùmhail ann cuideachd de ghrunn shreathan àiteach de bacteria ùir buannachdail, enzyman, fungasan, agus factaran brosnachaidh fàs planntrais. Nuair a thèid ullachadh gu ceart airson a chleachdadh, faodaidh gach unnsa còrr air 1.36 billean CFU (aonadan cruthachadh coloinidh) de fhàs-bheairtean buannachdail a thoirt gu buil.

Buannachdan Tòiseachaidh Compost BD Pfeiffer™ ​​Bidh an Tòiseachaidh Compost seo a’ cuideachadh le bhith a’ dèanamh cinnteach gu bheil ullachaidhean BD air an toirt a-steach gu ceart le glè bheag de eòlas air àiteachas bith-dhinimigeach. Chan eil coimeas air a’ bhuaidh compostaidh aige, a’ toirt a-mach briseadh sìos luath de stuth. Fo chumhachan ceart taiseachd, èadharachaidh, agus stuth organach (mar a tha air a thoirt seachad anns a’ cho-mheas Carbon/Nitrogen gu h-ìosal), nì an Tòiseachaidh Compost BD:

  • Dèan briseadh sìos stuth organach amh gu sgiobalta, ga bhriseadh sìos gu todhar nas sìmplidh
  • Ath-chruinnich na todhar sìmplidh seo ann an humus iom-fhillte maireannach
  • Ceartaich naitridean bhon adhar agus dèan e ri fhaighinn airson beathachadh lusan air dhòigh eile
  • Meudaich ruigsinneachd mhèinnirean, gan cruth-atharrachadh chun chruth a tha ri fhaighinn
  • Cùm an ùir agus leasaich a structar
  • Casg a chur air sileadh is nighe air falbh na h-ùire, agus lughdaich no cuir às do chreimeadh

Bidh nàdar sònraichte cinneasachaidh humus aig Tòiseachadair Compost BD a’ toirt a-mach compost àrd-inbhe làn de fhàs-bheairtean buannachdail san ùir agus humus colloidal. Tha na buannachdan a’ gabhail a-steach:

  • Structar na h-ùire nas fheàrr. Tha an ùir nas fhasa ullachadh agus àiteachadh.
  • Drèanadh uisge nas fheàrr. Tha uisge air a ghabhail a-steach nas fhasa agus a’ dol nas doimhne.
  • Tha fàs freumhaichean air a bhrosnachadh.
  • Tha sgaoileadh naitridean seasmhach agus gun chall.
  • Tha beathachadh air a ghleidheadh ​​agus air a dhèanamh ri fhaotainn. Tha gabhail a-steach beathachadh air a dhèanamh nas fhasa.
  • Tha meanbh-bheatha san ùir air a neartachadh agus air a chumail suas.

Tha aon aonad (aon unnsa) de BD Compost Starter gu leòr airson timcheall air 1 gu 1.5 tunna (no 1.5 gu 2.25 slat ciùbach) de stuth. Is e aon aonad an ìre as lugha as urrainn dhuinn a chuir air falbh. Bidh aon tunna na chiùb de stuth a’ tomhas gu cuibheasach 4.5’ x 4.5’ x 4.5’ airson a’ mhòr-chuid de stuthan a tha san amharc airson compostadh. Bu chòir gnìomhachadh aon unnsa a bhith gu leòr airson suas ri 1.5 tunna.

Published results & practical experience

A practical way to bring biodynamic preparations into your composting routine.

Pfeiffer Compost Starter is a prepared inoculant for compost materials. Published accounts describe its use in garden heaps and farm windrows, offering practical examples of the product at work.1, 2, 3

A garden-heap comparison

In a report published in English in 1967, Katharina Hanke compared two heaps made from the same plant wastes. One received Pfeiffer's B.D. Compost Starter; the other received the individual biodynamic preparations.

After five weeks Heap No. 1 was completely rotted, while Heap No. 2 was still in the midst of the process.2

This was a two-heap observation, with one heap per treatment and no untreated heap. “Completely rotted” was the author's assessment. When the finished composts were used for lettuce and kohlrabi, she observed no difference in growth or total production.2

A farm windrow routine

Patricia Smith's 2003 interview with Joe Francis describes three windrows of roughly fifty tons each, built from cow manure and hay. Francis used Compost Starter during construction and turned the material every seven days. The account reported compost ready for use after twenty-one days.3

The timing belongs to that farm's materials and management. The interview does not provide an untreated comparison or a standardized compost-maturity test.3

Put the experience to work

Use the current product instructions to prepare and apply Compost Starter. Keep track of your feedstocks, moisture, turning dates and progress toward readiness. Published experiences provide useful comparisons for your own composting routine.12

Frequently Asked Questions

How do I use the Biodynamic Pfeiffer™ Compost Starter?

Moisten one unit in a flat pan or dish with just enough water to make it pasty. Allow it to activate for 12–16 hours or overnight, then dilute the paste in enough water to thoroughly moisten each compost-pile layer as the pile is built.
What are the benefits of using the Biodynamic Pfeiffer™ Compost Starter?

JPI Starter brings BD 500, all six BD 502–507 compost preparations, and beneficial microbial cultures together for an actively managed pile. In a controlled 2026 comparison, compost treated with the included BD 502–507 set supported greater growth of tested compost-active bacteria at 120 days than corresponding untreated compost, especially in a mixed plant-and-manure pile. As the pile matures, look for these practical quality cues from JPI: a woodsy smell, uniform dark-brown color, and soil-like texture. Study: https://doi.org/10.1186/s40538-025-00891-y
How much compost can one ounce of Pfeiffer™ Compost Starter treat?

One ounce can treat approximately 1 to 1.5 tons of compost material, which is around 1.5 to 2.25 cubic yards.
What makes the Pfeiffer™ Compost Starter unique?

It combines BD 500, the complete BD 502–507 compost-preparation set, and beneficial cultures in one easy-to-distribute, one-ounce Starter. Activate it as a paste for 12–16 hours or overnight, then dilute and distribute it through each layer as the pile is built. One unit treats about 1–1.5 tons of starting compost material.
