Agroforestry As An Agricultural Alternative

#3 Fruit Trees Although many people dream of one day owning and operating an orchard or vineyard in the Okanogan Valley in southern B.C or on the Niagara peninsula in southern Ontario, with land prices approaching $100,000 an acre for good orchard land, it may be difficult to convince the spouse and the kids to make the big jump. What may be come as a shock to some, is that the western provinces can grow a wide variety of fruit trees, shrubs and vines that are commonly associated with warmer climates to the south.

While small fruits such as saskatoons, cherries and raspberries have been the mainstay of rural U-picks for decades, the prospects for apples, plums pears and even apricots are becoming more prevalent on the market gardening scene. The main reason for this shift is the consumer demand for fresh locally grown product. With prairie U-pick apples going for as much as $2.00 a pound on the tree while beef and pork are often languishing below the $1.00 a pound on the hoof, it small wonder why many livestock producers are considering switching sides.

#4 Nut Trees It may come as a revelation to some, but years of global warming is not required before establishing a nut grove on the farm. Some of the trees that can be grown on the prairies that produce edible nuts include the Black Walnut, Bur Oak, Butternut, and Hazelnut.

If you are looking for an RRSP for your children and grandchildren, can’t do any better than planting black walnut trees on your farm or acreage. These majestic trees add mucho dineros to the value of the property when they are growing, produce copious volumes of tasty, edible nuts throughout their life and have an enormous value when the tree matures. The wood is highly prized as a cabinetry veneer and in the manufacture of gunstocks that has resulted in astronomical prices with some trees fetching upwards of $10,000 each.

Nut production can begin after as little as 5 years after planting but the production of veneer wood is a generation or so down the road. As an added bonus the black walnut roots produces it own herbicide called “juglone” that keeps the ground around the base of the tree relatively weed free.

#5 Sap Trees. Although maple sugaring is usually associated with eastern Canada, it is now possible to grow newly developed sugar maple varieties in sheltered locations throughout much of the Prairie Provinces. The major problem is that it takes up to 40 years for the sugar maples to become big enough to initiate sap production. The solution for many would-be sugar shackers is to harvest sap from alternative species.

Sap from Manitoba maples has about half the sugar content (about 3%) of sugar maples but there are millions of mature Manitoba maples throughout the western Canadian agricultural belt. Originally planted in the 1930s as part of the PFRA shelterbelt program, these trees are not only ready for tapping, but are in long straight rows close to county roads. The sap from Manitoba maples can be gathered and processed in exactly the same way as sugar maples.

Surprising as it may seem, but birch trees also produce a sugar sap that can be more valuable than maple sap. Since the sugar content of birch sap (1-2%) is much lower than maple sap, it is rarely boiled down into syrup but is actually bottled almost straight from the tree as a medicinal drink or distilled and combined with carbonated water to make “Birch Beer”. Birch beer is popular in the northeastern United States and in Atlantic Canada, while medicinal birch sap is a multi-million dollar industry in European Baltic countries.

With the price of feed grains skyrocketing, many grain farmers are laughing all the way to the bank while numerous livestock producers are finding difficulties making it from year to year. Regardless which situation your farm is currently experiencing, it is a perfect time to think about diversification as a hedge against future market reversal. One of the simplest ways to fancy up an every day cash flow is through agroforestry

Although planting trees as a long term investment has been known for years, what may come as a surprise to many landowners, is that the most valuable aspect of trees are rarely found in the back of a logging truck. The long, medium and short term return generated from small acreages of trees is often nothing short of spectacular. Listed in the next 5 weeks in order of importance are 5 types of plantations that can reap some big rewards

Building and Energy Efficient Home for Less - Tip 1

#1 Shelterbelts Surrounding the House Properly positioning trees shrubs and perennials around the house is cheapest, most effective method of achieving energy efficiency in the home. The plants and trees not only help keep the house warm in the winter by blocking the northwest wind, but help keep it cool in the summer by blocking the hot summer sun.

The most important rule of thumb to follow is never plant evergreen trees (including spruce, pine, fir and cedar) on the south or east side of the house. While evergreens in these locations are effective in shading the building against the blistering July sun, they also prevent the solar radiation in the winter from doing its part to mitigate heating costs. In fact the shade produced by a mature spruce tree growing on the south side of the house can increase the homeowner’s heating bill to the tune of $250 or more per year.

Instead of using evergreens to grace the southern exposures leaf trees or vines should be used. The leaves provide a barrier to the incoming solar radiation in the summer, while in the winter, the bare branches allow the sun’s rays to reach the home unabated. The other advantage of using trees and vines extensively around the house is that they provide a seamless transition from the house to the landscape.

Have the Main Windows Facing South.

Sunlight shining through a square foot of glass will produce 400 Btu’s per hour of heat in the winter. In fact 200 square feet of glass facing south has the potential to completely silence that 80,000 Btu per hour furnace even on the coldest days. As luck would have it, prairie farmers live in the sunniest part of all of Canada, so to not use it to help reduce the gas bills would be a travesty.

The trouble with windows is that since they have a low R-value, when the sun is not shining at night or on cloudy days, they will lose a lot of heat. Fortunately installing lined or quilted curtains easily solves the window’s low insulation problem. By simply closing the curtains when the sun sets or the clouds build up it is possible to increase the R value of the window by a factor of five or more instantly..

Not only does the additional sunlight in the winter months help reduce the energy bills but it can also make you feel happier. Many people on the prairies suffer from Seasonal Affective Disorder (SAD for short) that is attributed to a lack of sunlight in the northern latitudes. The symptoms of the “Midwinter Blues” such as lethargy and irritability can be alleviated by addition of full spectrum sunlight as any one who vacations in tropical climates can attest.

Another trouble with south facing windows is that they let in daylight all year long. Those same windows that saved you from bankruptcy in winter have the potential to turn your whole house into a shake and bake oven in the summer. Providentially, with the correct the placement of shade producing nature of trees and shrubs, all is well again.

No Windows and Doors on the North Wall.

The north wall is the coldest wall on the house and since both windows and doors typically have the low R values, installing them on a north wall makes absolutely no sense from an energy efficiency point of view.

The north wall is the coldest wall on the house for a couple of reasons. From the Autumnal equinox on September 21 to the Vernal equinox on March 21, the sun is always in the southern sky and therefore the north wall never receives direct sunlight and is in perpetual shade for these 6 months. The low insulation values of doors and windows on this side allow copious amounts of heat to leave without receiving any solar gain in return. In fact homeowners can receive the biggest bang for their insulation dollar by adding some to the north-facing wall.

Compounding the lack of sunlight on the north-facing wall is the cooling effect of the northwest winds. Windows and doors are notorious for letting in drafts because due the process of linear expansion. What this two-bit phrase means, is that materials expand when it is hot and contract when it is cold. Since both windows and doors are each made of several different materials that expand and contract at different rates, it means that when the temperature changes, gaps are created between the materials and these gaps let in the cold outside air.
