生物动力是否能提高质量?

生物动力技术从未忽视过农业常识,它是对你已经在做的正确事情的补充,而不是削弱。

Does Biodynamics Improve Quality? - The Josephine Porter Institute
实践证明,如果使用得当,生物动力法可以提高作物的营养密度、贮藏寿命、抗病虫害能力,甚至还能改善口感。但是,正如鲁道夫-斯坦纳本人所强调的,生物动力法是对农业常识的补充,而不是完全取代一切。你必须继续平衡土壤的酸碱度,哪怕只用木灰(斯坦纳指出,钾盐和钙在自然界中并没有达到我们所需的平衡),你必须提供某种形式的堆肥,最好是用你农场里的材料,尤其是用堆肥好的反刍动物粪便。

在艾德-勇的书《我蕴含万物》中:我们体内的微生物和更广阔的生命观》一书中,他描述了人类(和老鼠)是如何在肠道无菌的情况下生活的--我们的肠道并不特别健康,但我们可以勉强度日。但对于反刍动物来说,如果肠道无菌,它们会在几周内死亡。为什么会这样呢?因为奶牛主要不是靠吃食物为生,而是靠肠道发酵的副产品为生。奶牛培养的微生物会在排泄物中产生大量维生素!这就是为什么在印度,牛尿被视为多种维生素的部分原因--它绝对富含营养。

在生物动力学中,我们的肥力建立在牛的内在工作基础之上。我们希望我们的土壤能够像牛一样,能够吸收贫瘠的青草,将其发酵,并为周围的生命生产出超级丰富的维生素。这正是我们想要的土壤,所以我们总是从 500 头牛的牛粪开始。

生物动力技术是对你已经在做的正确事情的补充,而不是减法。

Frequently Asked Questions

What kinds of field evidence does this article use to discuss biodynamic quality?

It draws on long-term Swedish potato trials and Washington and Wisconsin comparisons measuring crop quality, roots, soil microbial biomass, and particulate organic-matter carbon.

What potato-quality outcomes have biodynamic field studies measured?

In two long-term Swedish field trials, biodynamic-system potatoes were more closely associated with higher dry matter, taste-quality scores, and the relative share of pure protein than conventional-system potatoes. The comparison concerns complete growing systems. Kjellenberg and Granstedt, Foods (2015): https://doi.org/10.3390/foods4030440

How does biodynamics build on good farming practice?

The article presents preparations as additions to practical farm care: balance soil pH, supply compost—ideally from farm materials and well-composted ruminant manure—and use BD 500 within a broader fertility program.

How do cattle contribute to the fertility system described in the article?

Cattle provide manure that can be well composted and returned to the soil. The Swedish biodynamic potato system included composted cow manure together with crop rotation and other biodynamic practices.
