| Attracting Birds to Gardens
The sounds and movements of birds really bring a garden to life. Their search for food, their mating behaviour, their squabbles over territory, or nest building can provide many enjoyable hours for the keen observer. With careful selection of plant varieties, and their placement within your garden, you can have a major impact on the numbers and types of birds that will visit and take up residence in your garden....(Excerpt from page) Click to read more
| Avoiding Sun Damage
Bright sunlight and long days make summer a real pleasure; but not everything about the sun is good. Some people will tell you that you need sun exposure for vitamin D production; but research shows that most of our vitamin D needs come from food we eat.

| Soil Structure Problems
Soils are naturally a series of layers. The top layer or top soil will naturally have higher levels of organic matter. It is high in nutrients, and it absorbs and holds water when it rains, because the organic matter acts like a sponge.
When soil is plowed though, the top layer is mixed with lower layers; and that changes this natural structure. Tillage isn't the only reason why soil might degrade, but it is significant.
When soil degrades, no matter what the reason; there can be unwanted consequences.
Among other things their may be a reduction in the ability to absorb water; resulting in increased runoff which can cause erosion. ...(Excerpt from page) Click to read more

| What is Solar Radiation
As the solar radiation passes through the atmosphere, part of it is absorbed by the atmospheric gases, such as the ozone, water vapour and carbon dioxide (CO2). Another part of it is reflected back into the universe by the clouds. Some of the heat is dispersed in many directions by the reflection caused by tiny particles present in the air (e.g. gas molecules in the atmosphere, dust, etc). ...(Excerpt from page) Click to read more
