Soil is a mixture of tiny rock particles, living organisms, chemicals and the remains of dead plants and animals. Spaces between the particles will also contain a certain amount of air and water depending on the type of soil.
Rocks near the earth's surface are slowly broken down in nature by a process called weathering. Eventually small particles such as sand, silt and clay are formed. These particles create the environment for billions of mostly tiny organisms to live. Larger organisms such as earthworms and insects are also found in soil. A healthy soil is teeming with life.
The main aim as a hobby farmer is thus to try to improve soil health by good management. Poor management can lead to a loss of fertility and degradation of the soil. In extreme cases the valuable topsoil can also be blown or washed away. In the end poor soils lead to low quality crops lacking in nutrition.
Below are examples of some checks I plan to carry out on my farm with the aim of improving soil fertility.
1) Carry out a pH test in different places. This test will determine if the soil is acid, alkaline or neutral. Most plants prefer a pH level around 6.5. Should the pH level be too (below 6) corrections can be made by adding lime. Should the pH be too high (above 7) this can be lowered by adding plenty of organic matter and mulch. Extremely alkaline soils can be changed by adding ground sulphur.
2) Check the soil texture of the soil by rubbing some moist soil between your fingers. This will help to determine the type of soil present. Sandy soils will have a coarse feel. These soils dry quickly. Adding lots of organic matter will improve sandy soils. Very sandy soil can also be improved by adding clay. If the soil feels sticky when rubbed it contains too much clay. Clay soils drain slowly and are difficult to work when wet. Adding gypsum will help in most cases. Should the soil have a good balance of sand, silt and clay you will be blessed with a loamy soil. These soils are generally easy to manage and do not require treatments.
3) Check the level of organic matter in the soil. This can be done by shaking a handful of soil in a jar and seeing how much organic matter floats to the surface. If only a thin layer is present on the surface, lots of organic matter needs to be added. This means more microorganisms can be sustained, these in turn will release essential health giving chemicals needed by plants.
The above tests are simple to carry out and much information is available on these topics. Further tests require equipment or a soil testing company to analyse the soil. These include salinity, especially if bore water is used. Individual soil nutrient levels for Nitrogen, Phosphorous and Potassium as well as trace element levels can also be measured. Other aspects such as fertilizer application and cultivation practices to maintain soil structure also need attention.
Soil care requires years of experience and looking to older gardeners will give you lots of essential tips. Also, experienced gardeners can often identify soil problems by looking at the general appearance of plants. Getting a spade and digging around will give you information about conditions such as waterlogging and excessive dryness.
Do all you can to look after your soil and allow your plants to carry out the magic task of turning fertilizers and compost into healthy and nutritious food.

Ground Beneath Your Feet
Let's consider the impact of business model innovation on the geological thinking behind underground gold mining, an industry that has had one of the most stable business models in the world. Based on archeological records, it is estimated that that business has been around for thousands of years.
Until the industrial revolution, when power and explosives could be applied in the mines and stratigraphic maps were created, the business model and methods used were essentially unchanged. You put more effort into wherever you found some gold.
You drilled lots of exploratory holes to see what you could find, and made three dimensional maps of what you learned to suggest where the gold might be found by extending the strata you knew to be gold bearing. Then you drilled some more.
Until recently, the only innovation since then was the development of futures markets for gold, so that miners could sell their future production and inventories when they wanted to reduce uncertainty or risk.
In March 2000, the gold-finding part of the business model was laid to rest for all time by Goldcorp Inc. The company issued a challenge to all of the world's geologists to find more gold in its Red Lake Mine. That mine was already tapping into one of the world's richest, highest-grade gold deposits.
Everything the company knew about the mine was shared with the geologists through the Internet. Substantial cash prizes were offered for the best ideas. This occurred at a time when gold prices were at a near-term low in constant dollar terms.
As a result of having little else to do in the depressed market, many of the world's best geologists participated. Over 1400 prospectors registered for the challenge. A year later, the company announced that the winning submissions had located 6 million additional ounces of gold.
With further testing, that number may grow. The ultimate revenue from mining that gold will exceed one billion dollars and profits will probably be hundreds of millions of dollars. The cost of the prizes was $575,000. The prices cost less than the unproductive exploratory drilling that would otherwise have occurred.
To fully appreciate this experience, you should know that this is mine has operated for a lone time. Most would assume that there was little more gold to be found in it that has not already been identified.
To build on that success, the company launched its Global Search Challenge in March 2001. That contest looked for important mineral deposits worldwide over the following two years, and offered two million dollars in prizes.
This amounts to a second model change in only one year. This time, Goldcorp not only leveraged its own information, it also leveraged that of everyone else as well as their ability to interpret that information. Goldcorp will be able to access every geologist who learned something that a mining company is not yet exploiting.
And it can then simply use the best ideas. The mining industry should expect that the business model for finding minerals will continue to rapidly change.
When other industries hear about Goldcorp's success, we can expect to hear about similar challenges being offered for new information and knowledge to solve problems and find better opportunities. In the future, this new model will undoubtedly set off yet another new business model.
Companies will acquire businesses and properties that have had little information and knowledge applied to them, following a similar contest to identify which ones are the best to buy. Then there will be a worldwide contest to decide which options for improving the businesses and properties are the best ones.
