Ask for copies of any reports that illustrate the makeup of the local population. Are you living in an area where the population is predominantly retired What new housing estates are being planned What developments are currently underway Take as much published information as possible away with you. Even if you don't use it now, information like this is invaluable for future business planning.
Your lot or farmstead's soil is important because it must support both plants and man-made structures. Soil tests, available through your county Extension office, will tell you whether your soil has the proper chemical makeup for good plant growth. Your county Soil Conservation Service can determine whether the physical properties of your soil are suitable for landscape structures.
The characteristic properties of many herbs and spices are largely due to the presence of essential oils, which arc volatile substances that contribute to the aroma (or the essence) of certain plants. Chemically, these oils arc classified as tcrpencs, which arc unsaturated hydrocarbons with the common building block of C 0H16. Essential oils impart flavor to foods in addition, many have medicinal properties. Some essential oils reportedly function as antibiotics, decongestants, stimulants, or pain relievers. Essential oils can be found in various plant organs, but they typically occur in leaves, flowers, or fruits. For commercial applications, the essential oils arc cxtractcd by several methods, including steam distillation, expression, and solvent extraction. They may then be used in processed foods and in rnanuiacturing cosmetics, soaps, and candlcs. The recent interest in aromatherapy has greadv increased the use of essential oils, and they can now easily be purchased in many...
Sales are still limited to the high price, low-volume markets that match the current low world production of about 1,500 t yr. The cosmetics and skin-care industry buys most of present production and uses the oil in its natural form or modifies it to a cream or wax. The majority of oil is consumed in the United States and Europe. In 2003 the world trade in jojoba oil was estimated to be worth
Soybean, oil palm, rapeseed and sunflower are the predominant oil crops in the world (Dyer et al. 2008 also covered in Chaps. 21, 24). Other important oil crops are peanut, cottonseed, palm kernel, coconut and olives. However, more than 60 of the annual vegetable oil production is derived from soybean and palm oil. As summarized by Dyer et al. (2008), seed oil from these major oilseeds is mainly composed of the five major fatty acids palmitic acid (16 0), stearic acid (18 0), oleic acid (18 1A9), linoleic acid (18 2A9,12) and a-linolenic acid (18 3A9,12,15). Vegetable oil enriched for fatty acids uncommon to these major oilseed crops and fatty acids with additional functions provide a huge potential as chemical feedstock for the industrial production of detergents, cosmetics, drying oil, paint, ink, specialized lubricants or plastics providing a much higher versatility than mineral oil (Metzger and Bornscheuer 2006 Dyer et al. 2008). Consequently, engineering the lipid composition of...
A less scientific approach to the choice of material for plant-based substrate is an economical approach. In order to make compost applicable in practice, it has to be able to compete with the prices on peat. Clover-grass is grown in large quantities in Denmark and could be used without large expenses. This is more uncertain when it comes to the structural elements. Wheat straw could be used at low expenses but results showed that wheat straw alone was not suitable as growing medium as stability and water retention capacities were not satisfactory (Dresboll et al., in prep Dresboll and Thorup-Kristensen, submitted A). Growing hemp and Mischanthus straw would be somewhat more costly however, hemp is becoming a more common crop for different purposes, the leaves can be used for tea, the seeds for oil production for cosmetics and fibres for robe, clothes and insulation. Both fibres and stem could though be produced without being much more expensive than peat. Mischanthus straw is grown...
Starch is the major reserve carbohydrate in plants. Potato, maize, cassava and wheat provide the main sources of energy in the human diet, but also serve for many industrial processes like adhesives, cosmetics, detergents, paper, textiles and pharmaceuticals (Davis et al. 2003). Starch is also used for the production of biodegradable plastics as an alternative to petroleum-based products. However, native starches from various plant species have limited physiochemical properties, and thus are directly suitable for only a few specific end uses. For many industrial uses, enzymatic and chemical treatments, it is necessary to improve the usability of starch. The modification of starch is possible by using biotechnology to alter starch composition or to modify starch synthesis (Chap. 11). Out of many examples for starch modification, we describe one example for altered starch composition. The ingredients for cosmetic creams, lotions, powder, perfumes, lipstick or makeup come from a variety...
Transformation is most simply defined as a change . In the plant biotechnology community, transformation can be a little more precisely defined as the process of DNA introduction into a plant cell, leading to a permanent change in the genetic makeup of the target cell and its derivatives.
Most herbalists prefer to use ceramic or glass containers to mix and store herbal products. However, it's fine to put a monthly supply of your homemade cosmetics in plastic containers to avoid the chance of broken glass. Be sure to label your homemade herbal products, including both the date and contents.
One of the more adventurous horticultural professions is that of the plant collector. The earliest recorded expedition was by the Egyptian queen Hatusu (Hatshepsut) in approximately 1495 B.c. The sought-after plants in this trip were those that produced frankincense and myrrh, used in Egypt for embalming, incense, cosmetics, and medicine. The live trees were transported from the Land of Punt (coastal Somalia, Eastern Sudan, Eritrea) via the Red Sea, Gulf of Suez, and the Nile River.
One of the most recognized and popular scents for cosmetics, toiletries, and aromatherapy, lavender (Lavandula) also adds drama to your flower garden. Several species exist, all of which have needlelike foliage and spikes of purplish blue flowers. The English lavender varieties, such as purple Hidcote and Munstead, grow up to 24 inches high and are hardy through Zone 5. Pink-flowering varieties include Hidcote Pink and Miss Katherine. Other species are less hardy but equally appealing, including spike, French, and fringed lavenders.
A soil in which vegetables can thrive generally contains solid matter and pore space in approximately equal measure. Moisture should occupy about half the pore space, air the other half. Most of the sold matter, about 43 to 45 percent of the entire soil makeup, should be mineral the rest of the solid matter (5 to 7 percent of the soil composition) should be animal and vegetable organic material.
