The One

These preparations are the purest quality that I have ever sourced. I know they have been made with tender loving care and the finest of ingredients. Absolutely in line with our farm’s 178 year tradition of biodynamic farming practices.

We are currently amending a large garden with mostly clay soil. Once that has been completed, we will make and spray the product around the area. Unfortunately, we don't have a current experience to offer. Spring may be our best tell tale when it has had time to work with the elements. Thank you

Such high quality products. Bless yall for making these preparations.

Biodynamic Pfeiffer™ Field and Garden Spray

Field and garden spray

It's not only for farms and gardens, but for the whole earth. My flowers and trees are so vibrant from its use, the neighbors are interested in what it is that I'm doing differently in the yard. Essentially the only difference is using field and garden spray. In the light of the harms coming to the Earth from data centers and fracking extraction practices, there are small things we can do to help nature in our yards and communities. Working with the BD preps is one of them. I'm grateful for the Josephine Porter Institute for making these preps available!

BD 508 and Field and Garden spray received safely.

I received both BD prep last week, my daughter hand carried from CA. The BD 508 is being fermented now will be ready for use around 1st week of March. I am reading more about the Field and garden spray for guidance on how to use it. I will surely update you with the results. Thank you for allowing me to be a part of this wonderful mission.

The Place

This is the place of knowledge and understanding of many great ideas. They are My connection to the past.

Eridanus

I mixed the Pfeiffer Field and Garden spray with some lukewarm pond water from my backyard.
Since it has this dusty texture like cocoa powder it takes a bit to absorb with water.
So I did let it settle till following afternoon as recommended and then just kept stirring & stretching it with water.
Over yet another 12 hours I kind of applied all of it to front and backyard.

High expectations !

The Preparation arrived here this morning - i have stored the llittle plastic bag in a big terracotta pot on top of manure-compost made with QR, covered with a fitting wooden lid, dark and moist and cool. Today is a day of 'cosmic chaos', and according to Pappa Wiebe Soepboer, a good time for new beginnings.

Thanks for the shipment. I have to admit that the Uline padded mailer #4 was a trifle tight, so the contents were somewhat cumpled. I appreciated being able to pay in Canadian dollars, but resented the customs duty Canada imposed to pass the border. Not your fault, but that of the Orange Man in Washington. I won’t rate the spray, but have no doubt that it wlll be superb. As yet, no time to use it.

It's too early to tell this season.

But in the past I seem to have had good results both in my container garden and when I use it in active aeriated compost tea.

Biodynamic Pfeiffer™ Field and Garden Spray

Magical!

I’ve been using Pfeiffer Spray on our tiny yard several times a year for years. Our plants thrive, and I value its impact on the neighborhood and the universe 💫✨

Field & Garden Spray and my pecan crop

I began using this product 2 years ago. I am not that knowledgeable about biodynamic preparations so using this product was a good start for me. I have lived on my 2 acres (with poor quality soil) for 12 years now. The previous owners used pesticides which I do not use. I have been hoping that eventually the trees would recover from the pesticide use, and then I would have a good crop. Last year was the first year that I had an amazing pecan crop from my 15 trees. (I had even enough to donate to the local food bank.) I wasn't expecting another crop this year because we are in a drought situation. Yet, I have another amazing crop. It has to be the Field & Garden spray. I have done nothing else different than using this product for the last two years.

Too Soon to Tell Much

I did receive my order in a timely manner, and had the instructions as to what to do with it, but did not have time to put it on my compost piles between 8/7 and 8/10 or there abouts. I will update later, after I spy my next window of opportunity, hopefully. I look forward to upgrading biodynamically in the garden!

Detalhes do produto:

Entre os nossos itens de venda mais populares, os produtos Pfeiffer™ foram criados na década de 1940 pelo Dr. Ehrenfried Pfeiffer com o objetivo de ajudar a tornar a biodinâmica mais acessível a jardineiros domésticos, agricultores convencionais e compositores. A JPI é a proprietária exclusiva dessas fórmulas patenteadas.

Ehrenfried Pfeiffer descobriu que o uso do Field and Garden Spray em apenas seis semanas aumentouo nitrogênio disponível no solo em 500%, o fósforo em 833% e o potássio em 260%. Maisinformações podem ser encontradas na série de três volumes de palestrasde Pfeiffer .

O Pfeiffer™ Biodynamic (BD) Field; Garden Spray contém todos os componentes incluídos no Compost Starter mais uma quantidade adicional de BD #500. Use durante o plantio ou transplante para estimular a germinação e o crescimento das raízes e durante o plantio de culturas de cobertura para aumentar os microorganismos do solo que ajudam na decomposição e na transformação em húmus estável. Também pode ser usado como spray foliar ou embebição de sementes. Uma unidade pode ser dividida para tratar áreas menores. É um excelente tratamento para jardins, pastagens e campos de feno de todos os tamanhos.

Composição do Pfeiffer™ BD Field and Garden Spray
Esse potente spray contém os preparados agrícolas biodinâmicos BD #500, #502, #503, #504, #505, #506 e #507, que conferem a esse produto sua eficácia exclusiva. Ele estimula e atrai uma gama completa de microflora e fauna do solo, o que é benéfico para acelerar a decomposição da matéria orgânica sem a fixação de nitrogênio ou outras ações retardadoras. Após essa decomposição, há um acúmulo subsequente de compostos de húmus úteis. Cada onça, devidamente ativada para uso, pode produzir mais de 5,6 bilhões de UFCs (unidades formadoras de colônias) de organismos benéficos.

Benefícios do Pfeiffer™ BD Field and Garden Spray
O BD Field; Garden Spray auxilia na formação de húmus em materiais orgânicos já presentes na camada superficial do solo. Deve ser usado durante o plantio e o transplante para estimular a germinação e o crescimento das raízes, e durante o plantio de culturas de cobertura para ajudar na transformação de materiais orgânicos em húmus.

Uma unidade do BD Field & Garden Spray trata um acre de terra. Ele vem em unidades individuais ou múltiplas, mas uma unidade é a menor quantidade que podemos enviar. Se o seu jardim tiver menos de um acre, ative apenas 1 colher de chá rasa (1 colher de chá). Isso proporcionará uma cobertura de 1.000 pés quadrados. A ativação de 1 colher de sopa rasa (1 colher de sopa) cobrirá 3.000 pés quadrados.

Published results & grower experience

Bring biodynamic preparations into your soil and field management.

Pfeiffer Field and Garden Spray is formulated for soil and field applications, including work with incorporated crop residues. Published vineyard accounts offer a practical example of its use alongside cover-crop management.^{1, 5, 6}

The Grgich Hills experience

In a published interview, Ivo Jeramaz described a comparison begun in 2007 with fifty treated acres and a fifty-acre control. Juice nitrogen in five of six treated blocks reportedly rose from approximately 150 ppm the previous year to 200 ppm after Field and Garden Spray use.⁵

A later account identifies the measure as yeast-assimilable nitrogen (YAN) and reports no increase in the untreated blocks. YAN describes nitrogen available to yeast in grape juice. These are published grower accounts of a commercial comparison; they do not supply a randomized statistical analysis.⁶

A grower's recommendation

Jeramaz's interview, published in Winter 2010-2011, includes this recommendation:

Nonetheless, I would highly recommend it where possible, especially if you have good moisture and good cover crops.⁵

Moisture and management mattered. The interview reports little improvement in dry 2008 and later discontinuation because of application logistics. The 2015 account describes dry-year exceptions and eventually reducing annual application when YAN became too high for the wine being made. The accounts differ in their follow-up chronology.^{5, 6}

Put the experience to work

Follow the current product instructions for preparation, coverage and application timing. Record your cover crop, soil conditions and application date so that the reported experiences can inform your own observations.¹²

Frequently Asked Questions

How do I use the Biodynamic Pfeiffer™ Field and Garden Spray?

Moisten one 2-ounce unit with just enough water to make a paste and let it activate for 12–16 hours or overnight. Dilute it in the amount of water your sprayer needs to cover one acre; spray close to the ground on a calm day in the latter part of the day. Clean spray equipment first.

The dry blend contains BD 500 Horn Manure, BD 502–507 compost preparations, beneficial soil organisms, and other agents. It is intended for biodynamic field and garden soil treatment.

How much area does one unit of the Pfeiffer™ Spray cover?

One 2-ounce unit covers one acre. For a smaller area, activate 1 level teaspoon per 1,000 square feet or 1 level tablespoon per 3,000 square feet; use enough carrier water for even coverage.
