很抱歉，我无法直接访问或分析网页内容，包括您提供的链接。不过，我可以根据您提供的标题和描述来给出一个可能的总结。

标题：“Regenerative Farming Practices Require Unlearning Past Advice”（再生农业实践需要摒弃过去的建议）

可能的总结：
这篇文章可能探讨了再生农业实践与传统的农业方法之间的差异。它可能会指出，为了实现更可持续和生态友好的农业系统，农民和农业专业人士需要放弃一些传统的农业建议和做法。以下是一些可能的要点：

1. **传统农业的局限性**：文章可能会讨论传统农业方法，如大规模化学肥料和农药的使用，以及其对土壤健康和生态系统的负面影响。

2. **再生农业的原则**：介绍再生农业的核心原则，如轮作、覆盖作物、生物多样性、土壤健康和有机管理。

3. **需要转变思维**：强调转变农业实践不仅需要技术上的改变，还需要在心态和方法论上的转变。

4. **案例研究和实证**：可能包含一些实例研究或数据，展示为什么摒弃过去的方法对于推动农业的可持续性是必要的。

5. **教育和培训**：提出需要新的教育和培训方案来帮助农民和农业从业者学习新的实践。

debacle: The farmers already know regenerative ag and are executing certain aspects of it, but for most of the US the financial incentives aren't aligned and the mineral losses in heavily farmed soils will take generations to recover.<p>This is an economics problem not a knowledge problem.

debacle: 农民们已经了解再生农业，并正在实施其中的某些方面，但对于美国大部分地区来说，财政激励措施并不奏效；t对齐，重耕土壤中的矿物质损失需要几代人才能恢复<p> 这是一个经济问题，而不是知识问题。

whoitwas: Go look at videos from the 70s before we began ingesting chemicals and tons of calories. Everyone is half the size with 99% less body fat.

kaonwarb: I'm happy to support farmers who want to turn to regenerative methods, but I can't see them as a solution for feeding today's world. As the article itself notes:<p>> U.S. agriculture production tripled in the latter half of the 20th century, due in part to chemical inputs.<p>And, yes:<p>> But that came with an environmental cost — soil degradation, water quality issues and a loss of biodiversity.<p>I'm not downplaying those costs, and am happy to see a range of approaches. But this is not a serious proposal for feeding folks at scale.

kaonwarb: 我；我很乐意支持那些想转向再生方法的农民，但我可以；我不认为它们是今天喂养的解决方案；的世界。正如文章所述：<p>&gt；20世纪后半叶，美国农业产量增加了两倍，部分原因是化学投入<p> 而且，是的：<p>&gt；但这也带来了环境成本——土壤退化、水质问题和生物多样性的丧失<p> 我；我并不低估这些成本，我很高兴看到各种方法。但这并不是一个大规模养活人们的严肃提议。

photochemsyn: For large-scale agricultural food production capable of feeding millions of people, the question of double-cropping under regenerative practices is a tricky one. Modern industrial agriculture relies heavily on two crops per year on the same land, which relies on generous fertilizer and water inputs. Regenerative practices would prefer giving up on the second crop in favor of various methods of biomass accumulation, composting, soil generation etc over that time period.<p>Note one business opportunity for the regenerative sector could be organic healthy soil production. There's a demand for high-quality soil and this could make the second half of the year productive. This could go well with a mushroom production system integrated with composting.

photochemsyn: 对于能够养活数百万人的大规模农业粮食生产来说，再生实践下的复种问题是一个棘手的问题。现代工业化农业严重依赖于同一块土地上每年种植两种作物，这依赖于大量的肥料和水资源投入。再生实践更倾向于在这段时间内放弃第二种作物，转而采用各种生物质积累、堆肥、土壤生成等方法<p> 请注意，再生行业的一个商机可能是有机健康土壤生产。那里；这是对优质土壤的需求，这可能会使下半年的产量增加。这可能与蘑菇生产系统与堆肥相结合很好。

akira2501: > Before the Civil War, over half of the country’s residents were farmers, Jolliff said, and they worked with small parcels of land in diversified operations. The modern regenerative agriculture movement encourages that same type of farm diversification.<p>Yea, and before the civil war, we didn't have gasoline engines. You are never going to see a broad return to rural farming life ever again.

akira2501: &gt；Jolliff说，在内战之前，该国一半以上的居民是农民，他们以多样化的方式经营小块土地。现代再生农业运动鼓励同样类型的农场多样化<p> 是的，在内战之前，我们没有；我没有汽油发动机。你永远不会再看到农村农业生活的广泛回归。
