Introduction Soils are important for human health in a number of ways. Approximately 78% of the average per capita calorie consumption worldwide comes from crops grown directly in soil, and another nearly 20% comes from terrestrial food sources that rely indirectly on soil (Brevik 2013a). Soils are also a major source of nutrients, and they act as natural filters to remove contaminants from water. However, soils may contain heavy metals, chemicals, or pathogens that have the potential to negatively impact human health. This article will summarize some of the more important and direct relationships between soils and human health.
Throughout human history, our relationship with the soil has affected our ability to cultivate crops and influenced the success of civilizations. This relationship between humans, the earth, and food sources affirms soil as the foundation of agriculture.
Snapshot Come with David Murphy while he takes you through the influence worms had on human migration in times long past, how worms can make or break civilizations, how smart farmers like David Davidson who uses worms to double the carrying capacity of his land, or Bert Farquahar who could write out a cheque for $10,000,000 to buy another farm because of the canny way he used worms. See how David Murphy is able to take what the worms produce – on its own, a super plant booster – and quadruple its plant growth value by very simple means and how to blend it with rock dust to make the complete low impact but effective biological fertiliser for a few dollars only per tonne. Find out why worms ain’t worms, but then add David Murphy’s extraordinary knowledge and you have the key to super prosperity by a sustainable means.

Thank you Michael Butler for sharing this: It is not explaining the meaning of life but it sure helps. Well worth scrolling through if you haven't already. http://theoatmeal.com/comics/believe
Don’t you hate the expression, “At the end of the day”? It should only refer to that agreeable time when the daylight hours are winding down; the sun is setting, a drink would go down pretty well, it’s time for dinner soon, wonder what’s on the telly, etc.
The surge of farmer-owned value-added processing has been rapidly developing. Producers of various commodities have begun to increase investment in their farming ventures, not by the traditional method of expanding production, but rather through investment in initial or first stage processing of their agricultural commodities and through the second stage marketing of their commodities. To some extent, further marketing and processing have been driven by low commodity prices, but, in general, these trends reflect the philosophy of a growing number of producers that producer-owned markets, whether for processing or otherwise, are essential for farmers’ continued existence in agricultural production. Many types of value-added agribusinesses have been formed to further process raw agricultural commodities. Examples of such value-added agribusinesses include processing corn into sweeteners and ethanol; processing corn or soybeans into feed for hog production, fish production, and chicken and egg production; processing soybeans into structural board products; extruding oil and other related products from soybeans; processing hogs and marketing meat products; processing cattle and marketing beef products; and a number of other ventures (Campbell 1995).
Posted 6 Mar 2017, 3:25pm Cattle in front of portable trough PHOTO: Soils For Life believe the rain drops that are evaporating can be used for things like extra vegetation. (ABC Rural: Emma Brown) MAP: Mackay 4740 How do you capture every rain drop from the sky, how is it possible and what difference would that make for our farmers? The Soils For Life organisation is determined to work out how it can capture more rain for Australian farmers and the landscape. Their work is based on the 100-drop scenario developed by a scientist called Walter Jehne, as explained by Soils For Life chief of staff Natalie Williams. Media player: "Space" to play, "M" to mute, "left" and "right" to seek. 00:00 00:00 AUDIO: Natalie Williams explains how farmers can capture more rainfall (ABC News) "For every 100 drops of rain that fall on Australian landscapes and soils, these drops can be divided up according to where they end up," Ms Williams said. "Thirty-six drops go into the landscape itself, of that 30 go to vegetation, keeping grass green and trees growing and only six of those drops go into recharging the aquifers." Another 14 drops of the 100 go into creeks and rivers and eventually out to sea or Lake Eyre, depending on where you are located.
One of the biggest modern myths about agriculture is that organic farming is inherently sustainable. It can be, but it isn’t necessarily. After all, soil erosion from chemical-free tilled fields undermined the Roman Empire and other ancient societies around the world. Other agricultural myths hinder recognizing the potential to restore degraded soils to feed the world using fewer agrochemicals.
Nutri-Tech Solutions (NTS) has specialised in cost-effective solutions for the large scale (broadacre) farming sector and our research and product development in this arena has really paid dividends since we began expanding into Asia. It turns out that what works for cereals, legumes and brassicas also works for rice. We have found that our efforts to create the "biggest bang for the buck" for Australian broadacre growers, is truly appreciated and embraced in rice-producing countries like India, Malaysia, Vietnam and Cambodia. During my recent seminar tour of North America, we found that Canadian cash croppers are also reporting impressive benefits from these inexpensive programs. This experience in multiple locations has enabled us to fine tune and field test concepts and products, to the point that we can now offer an exciting, three-step program for the upcoming Australian planting season.
Australia is known as the lucky country and you would certainly think that listening to Bruce and Heidi Davison. However, the story of this modest couple is not one of carefree serendipity but of diligence, thoughtfulness, and thrift. Their journey shows fortune benefits those who can link ecology to productivity by building biological capital and saving cash.
