Unnatural Fear of Roundup – Understanding Small Numbers

If you spend time understanding the science behind Roundup and glyphosate, it’s active ingredient, you soon realize that this is a safe chemical compared to many other chemicals, even ones liberally used in the home. Why is it then that so many people fear Roundup?

Probably the biggest reason is great promotion by the anti-Roundup and anti-Monsanto crowd. That is one powerful force, that brings one misleading article after another to the attention of a lot of people.

I think that another reason for this fear is our inability to understand very small and very large numbers. A recent research study found glyphosate in natural water systems and I have seen it posted by several people as proof of a real problem that needs to be feared. If these people simply understood small numbers, they would not fear the report or Roundup.

Compost Tea NPK Values

Compost tea is reported to be great for growing plants and some companies even call it a compost tea fertilizer. What is the NPK value of this magic potion?

I started this post about a year ago and at that time there were many products on the market but I could not find one that provided the Compost Tea NPK value. I checked again today and was surprised that the number of compost tea products available is down significantly. Maybe it was too expensive to ship all that water around the country? Maybe it did not work and people stopped buying the product?

Interestingly, the number of commercial DIY kits for making your own tea is up significantly. When you click on Google images for ‘bottles of tea’ you are taken to pages selling kits. Even with kits the same question needs to be asked. What is the NPK value of the tea these kits produce. Very few of the manufacturers I looked at provided such information, but many did say their compost ingredients were the best. Easy to say if you don’t give any data.

Even if you are not interested in compost tea – the following discussion will show you how companies are misleading consumers.

In this post I will look at how this myth got started and discuss some real facts about native bees.

Kamal Meattle – Plants and Air Purification

In 2014 I wrote a post called A Garden Myth is Born – Plants Don’t Purify Air, which has become one of my most popular posts. A recent comment on that post about a video by Mr. Kamal Meattle has prompted me to write today about another story related to plants purifying air.

Mr. Kamal Meattle has become well known for a short TED Talk video where he talks about converting an office building in New Delhi, into the cleanest building in India. His secret is the use of air purifying plants.

Today I will dig deep into this myth and uncover some surprising facts. Then I will review the latest research on the subject.
