(Articles) Common Plants Can Eliminate Indoor Air Pollutants


Adapted from Science Daily

Of the 28 species tested, Hemigraphis alternata (purple waffle plant), Hedera helix (English ivy), Hoya carnosa (variegated wax plant), and Asparagus densiflorus (Asparagus fern) had the highest removal rates for all of the VOCs introduced. Tradescantia pallida (Purple heart plant) was rated superior for its ability to remove four of the VOCs.

(Article) Diet of Contaminated Insects Harms Endangered Carnivorous Plants

Scientists in the UK are reporting evidence that consumption of insects contaminated with a toxic metal may be a factor in the mysterious global decline of carnivorous plants. Their study describes how meals of contaminated insects have adverse effects on the plants.

“So, the weather has broken and the northeast monsoons are finally done. It’s funny how we tend to forget that “monsoon” refers to the winds, and not rainy weather.”

(Article) The Training of the Shrew: Pitcher Plant Evolves Into Toilet

Pitcher plants are carnivorous and usually eat insects for nutrients and nitrogen. But in the highlands of Borneo there are not enough for it to survive on insects alone, so the pitcher plant evolved into a toilet plant, complete with standing lid that serves an unusual purpose.

Nepenthes pitcher plants are typically carnivorous, producing pitchers with varying combinations of epicuticular wax crystals, viscoelastic fluids and slippery peristomes to trap arthropod prey, especially ants. However, ant densities are low in tropical montane habitats, thereby limiting the potential benefits of the carnivorous syndrome. Nepenthes lowii, a montane species from Borneo, produces two types of pitchers that differ greatly in form and function. Pitchers produced by immature plants conform to the ‘typical’ Nepenthes pattern, catching arthropod prey. However, pitchers produced by mature N. lowii plants lack the features associated with carnivory and are instead visited by tree shrews, which defaecate into them after feeding on exudates that accumulate on the pitcher lid.

When it comes to cultivating a green thumb, gardeners perhaps need only look to their urinals and fireplaces.

That’s because human urine mixed with wood ash can help produce bumper crops of tomatoes, new research shows.

(Article) Enlivening Soil using Organic Fertilizers

With thanks to PetuniaLee from GCS who posted this link on the forum.

Adapted from a post from Woodleaf Farm.

Fertile soil is a mixture of well-balanced minerals, high organic matter, good aeration and bountiful soil life.  The biology or life in the soil is at its healthiest when the nutrients are plentiful and balanced, and there is sufficient oxygen.  The top few inches of soil is the most vital, holding about 70% of the life and 70% of the organic matter.  Below 6 inches the roots are feeding on mostly soluble nutrients since the micro-organisms are not able to thrive without sufficient oxygen.
