> Only nature can improve the soil, not human kind.
That I suppose would make a great mission statement for a hydroponics business. Anyway, I dont remove anything annually in my experience. I practice permanent agriculture (permaculture). Meaning that every system that I set up will sustain itself if I fall dead. I only add to the earth.
Only nature can improve the soil, not human kind. With our technology however, we can utilize these natural relationships to encourage information asymmetry between the plant and microbiology while the dirt underneath can repair itself from generations of abuse. What is the logic in insisting sand, silt, and clay are required to be considered "soil"? As long as the biology and organic matter are in the pot, nature will happen whether you like it or not!
The plastics used in biponics are expected to last in excess of 10 years, while the plastics used in "soil" growing (ie row mulches, etc) are ripped out and replaced on an annual basis! The sustainable metrics are indisputable. In the near future we'll be able to create polymers in-house with algae.
I'd be more than happy to share with you our budgets and P/L. We're not a closed book. Sustainability encompasses being economically viable, and teaching others. We're not fighting each other here, we're moving towards creating a resurgence in USA agriculture so we can start taking back the jobs and economic losses the "green revolution" led to.
Agriculture: Middle English, from Latin agrīcultūra : agrī, genitive of ager, field; see agro- in Indo-European roots + cultūra, cultivation; see culture.
Yeah, you must count the cost of producing plastics and metals to run your water farm. How long does it take for your plastics and metals to break back down into the soil and improve the soil?
Regarding good bugs bad bugs out: if you have "bad bugs", your system is ecologically out of balance.
This article would be news to the USDA, which has continued to reaffirm its commitment to hydroponic methods in organic agriculture. Apart (for the moment) of all questions of method and science, there has never been a 'ban' on organic hydroponics, and organic hydroponics continues to be a recognized method.This in itself should flag this article as somewhat suspect in its basis and assumptions.We could move from there to more interesting questions (agricultural soil is an aquatic environment...) - but that is a subject that should best be covered in a more balanced and better sourced article.
Truly an aggravating piece. Forgets to mention the benefits of hydroponics and namedrops Eve Balfour et al - We read Rodales' encyclopedia too

Have any of you actually ever been to a certified organic substrate operation?The key is locally grown organic produce can be grown year round with less inputs (because we recirculate water and ferts), lower utility consumption, and healthier plants with higher nutrient value than traditional soil grown. We have the ability to create biology in the pot keeping the good bugs in and the bad bugs out.Who ultimately wins here? It's the consumer, that's who. They get low cost LOCAL organic produce when the only other option would be grown in Mexico or South America. This isn't about you, or the soil. This is about simple economics, and those who can't adapt shall perish. Consumers win, young farmers win. Thanks for coming.
Why Is the Biodiversity Rule for USDA Organic Certification Not Being Enforced?
