World Soil Day - Build Soil. Help The World.

Last Thursday Americans celebrated Thanksgiving, which is meant to be a day of gratitude. (Okay, you don’t have to be grateful for mean old Uncle Cyrus). But, as we were celebrating, I believe it is safe to say that very few people thought to be thankful for the ground they were standing on. Or for the soil that produced their annual feast. World Soil Day hopes to change that by building awareness of the precarious position of our soil in the world today.

World Soil Day is an annual event put on by the United Nations. It is observed worldwide on December 5th with outreach, functions and even contests. The basic purpose of this campaign is to raise awareness of and advocate for healthy soil. Every year there is a theme that relates to soil; last year it was soil pollution and this year it is soil erosion. All around the world, our soil is eroding at an alarming rate. According to the UN, one soccer field worth of soil is lost every five seconds and it is not an exaggeration to say that the very food we rely on is being threatened. Climate change (which is an even larger issue) plays a part in increased soil erosion, but an awareness of the importance of healthy soil and good soil management can make a real difference on a micro level. Big changes can be made in small steps. Here is a cool little cartoon on soil health from the World Soil Day site.

Slash and burn farming in India

Aside from wind, water and other climatic factors, in many parts of the world soil erosion and degradation (when what soil is left is no good) is the result of human activity such as ecologically damaging farming methods like slash and burn agriculture. However, healthy soil loss from overgrazing, deforestation, mining and pollution is found everywhere. Combine all that with the extreme storms, drought and flooding that come from climate change and the need to do something is urgent. India, home to over a billion people, is already in crisis. Their largely poor and agrarian population is struggling and every year they are hit with intense monsoons and flooding. While the rains have always been a part of Indian life, they are becoming more and more extreme. The US is not immune to soil problems; this  enlightening article explains why we are running out of soil (including a super-interesting tidbit on the Roman Empire and their soil issues).

Here in Arizona, we have the premier example of water-caused soil erosion– the Grand Canyon. The canyon may have taken eons to be created, but we have all seen mini versions of it in our yards after heavy rains. This is a particularly thorny problem here in southern Arizona, where a good portion of our soil contains a Caliche layer. Caliche is, quite literally, as hard as concrete and does not allow water to pass through it. Combine this with the intense storms that we get during our summer monsoons (they can be bad, but not as bad as those in India) and there goes the surface soil.

Haboob bearing down on Phoenix

Additionally, we have extremely dangerous and damaging haboobs (dust storms), which are an exceptionally dramatic display of soil erosion. I once had the misfortune of being caught up in one of these on the freeway between Phoenix and Tucson. I am not a person who scares easily, but the whole experience was truly terrifying. Beyond the windshield everything is just a weird tan-orange color and all you can do is hope you don’t run into something and that nothing runs into you. Experts say you should pull over and turn off your lights (and pray nothing finds you), but I just got off on the first exit I could. I found out later that three people had died in a multiple car accident just ahead of me. If I hadn’t made that turn, I would have been a participant in that. Here is a video that really shows what they’re like.

Addressing soil health is often done best right from home. Here at ARBICO, we have been singing the healthy soil song for decades. We have gathered a great many excellent products that anyone can use in their yard or garden to encourage strong soil that’s rich in microbial life. You could begin with a mineral (or more than one)  like Soil Replenish (Elemite), Andesite, Glacial Rock Dust or Harvest Gold Premium Soil Conditioner (Silica). To add nutrients and jump-start your soil biology, you can add items such as Fulzyme SP, Earth Alive Soil Activator, and Neptune’s Harvest Humate Concentrate. Or you could go the one-stop-shop route and get our Healthy Soil Recipe or John & Bob’s Clay & Hard Soil Kit (excellent for Arizonans). These are just a brief sampling of what we have to offer in the soil building arena, there is much more in our Soil Amendments, Micronutrients & Biostimulants category..


If you are unable to contribute in changing the soil around you, I encourage you to consider recycling your green waste. And if you’re unsure of what to do with it once you’ve collected it, here is my blog with suggestions for that. If you are interested in reading more on soil building and/or soil in general, here is a link to some of our blogs that you may enjoy. Now, go out and get your hands dirty – and help the world!

Man, It’s Stupid Hot Out There!

No matter where you stand in the climate change conversation, it is undeniably HOT out there these days – outrageously, hellishly, suffocatingly hot! 200 million Americans are currently experiencing record-breaking heat, with many places expected to reach temperatures higher than those we’ll have here in Arizona. And don’t give me the “it’s a dry heat” refrain, an oven is also a dry heat. I have lived in places with high humidity and know how debilitating it can be and most of the places dealing with this heat wave will also have that humidity. The combination of heat and humidity is just plain miserable.

Never touch metal that's been in direct sunlight.

We Arizonans take pride in our ability to muddle through our summers. Most of us accept the heat as payment for having such mild winters. There are many strategies to get through, but when asked how one copes, my favorite response is “Live like a desert creature”. Simply put, avoid the sun at all costs, don’t over exert yourself and drink plenty of water. Seeking shade is a competitive sport around here in the hottest months; I’ve seen groups of people clumped together under the thin strip of shade a telephone pole offers.Even local reptiles know this game. Having said all that, many (probably most) Arizonans, myself included, are lucky enough to travel from air-conditioned homes in our air-conditioned cars to other air-conditioned locations. But, getting to that car in the parking lot and getting it cooled down can be pretty gnarly!

 

"Facekinis" in China - not creepy at all. 

People can wear lighter clothing (or add questionable sun protection like the image on the left) and adjust their routines in answer to excessive heat, but what is a  plant to do? The higher the temperatures, the more need for water; finding ways to stretch your water is key. In Arizona, Xeriscaping has long been a widely appreciated model for growing. With its emphasis   on water conservation, mulching and using heat   tolerant plants, it is an ideal solution for areas like   ours that experience heat and drought.The elimination or reduction of turf is also a key factor in Xeriscapes. Many people around the country still love their lawns, but in cities like ours where water is at a premium they have become less socially acceptable. I encourage every reader to reconsider their lawn and either eliminate or reduce them; it is a small but important way to serve the environment.

Adopting a Xeriscape approach to landscapes and gardening takes some planning ahead. This works well in Arizona because we always know it will be hot and dry. With current climate conditions being what they are, excessive heat and/or drought is a reality now for non-desert parts of our nation and, if you want to grow something, planning ahead is for everyone. Here are some ways you can build a heat tolerant green space; some take planning, but others offer heat help right away:

Soil Amendments – Building a soil that holds and properly distributes water and water-borne nutrients to plants is a solid foundation that gives plants the tools to fight the heat. You can chose something like Earthshine, a soil enhancer mix that contains biochar and other beneficial additives. Or a powder like Harvest Gold Organics Premium Soil Conditioner, which contains silica and micronutrients. Or even a single ingredient additive like the Elemite, also known as ARBICO Organics™ Soil Replenish™. Another (very affordable!) option is ARBICO Organics™ Rice Hulls. The bottom line is that any type of high quality soil amendment will bring you healthier soil, which means healthier plants that can better handle heat and drought stressors.

Composting & Mulching – You can increase your soil’s water holding capacity by up to 7 times by simply adding compost. You can use ready-to-go compost or begin making your own; we have options for you here. Mulch, mulch, mulch – in any form, by any name, just do it! Mulching options are many: coco coir like Prococo Coconut Coir, Hulless Oats and other cover crops and biodegradable weed block paper, which provides weed control as well as mulch. Another interesting option is Slug Gone. This sustainable slug (and snail) control product is made from wool and is placed in and around garden beds. It will swell from the moisture and make a scratchy mat that slugs will refuse to cross. In performing its slug control duty, it also retains moisture and reduces water usage.

Yucca in its native environment

Adjuvants – Another way to protect plants from heat stressors is to add adjuvants to their water. Yucca (Yucca schidigera) is a desert native and knows all the tricks to survive in such a harsh environment. Adjuvants like RAW Yucca Flow and Therm X-70 that use extracts from these plants deliver the secrets of the Yucca plant to your backyard. You can give your plants immediate heat relief by adding these adjuvants right away.

Covers – Use covers to protect your plants from the pounding sun. Here are many versions to choose from, or create your own. Here is a video to show you how.

Containers – Consider moving plants from beds to containers. Container planting makes water conservation easier and gives you the ability to move plants in and out of the sun.


Embrace heat-loving plants – Seek out and cultivate plants that are well adapted to hot weather. Here are some great heat-friendly plants that you are probably familiar with:
Sunflowers – with a name like that…
Amaranth - pretty – and you can eat it!
Echinacea – beloved by pollinators – and check out these cute earrings
Yarrow - native to temperate North America

Unless you live in the far northern regions of our country, you may be surprised to find there are native summer species waiting to be loved. Here in the Tucson, we have a fabulous source for desert-adapted native and heirloom plants thanks to Native Seeds/SEARCH. They have a remarkable variety of interesting seeds and stories that go with them.

Stay cool out there.
