产品详细信息：

配制好的 BD 500 可促进种子发芽、根系生长和腐殖质形成。在种植、移植或翻耕覆盖作物时使用。

该制剂由 Alex Podolinsky（澳大利亚）开发。在澳大利亚的实践中，虽然 Prepared 500 最初是在使用普通的 BD 500 两年后才开始使用，但现在，根据进一步的经验，几乎在每种情况下，从改用生物动力农业的一开始就应该使用它。该产品包含所有生物动力制剂，包括 BD500 牛角粪、西洋蓍草、甘菊、荨麻、橡树皮、蒲公英和缬草。

Frequently Asked Questions

What is the main benefit of using Prepared 500 Horn Manure?

Prepared 500 combines finished BD 500 horn manure with BD 502–507 for biodynamic soil care. A 2026 lab study found proliferation of selected compost-associated bacteria with an Italian 500K formulation; a 2022 apple-orchard study found time-dependent rhizosphere microbiome changes after an Austrian 500P extract. Those measured responses concern related formulations and microbial endpoints; direct JPI-batch and crop-yield tests are separate next steps.
How should I apply the Prepared 500 Horn Manure?

Stir one unit for one full hour in 3–5 gallons of water, then spray onto soil, preferably late in the day.
What area does one unit of Prepared 500 Horn Manure cover?

One unit, which is 1/4 cup, treats one acre of land.
What ingredients are included in the Prepared 500 Horn Manure?

It contains finished BD 500 horn manure plus six compost preparations: yarrow (BD 502), chamomile (BD 503), stinging nettle (BD 504), oak bark (BD 505), dandelion (BD 506), and valerian (BD 507). It does not include BD 501 or BD 508.
