Tree planting is the process of transplanting tree seedlings,
generally for forestry,land reclamation,
or landscaping purposes. It differs from the
transplantation of larger trees in arboriculture,
and from the lower cost but slower and less reliable distribution of tree seeds.
In silviculture the activity is known as reforestation,
or afforestation,
depending on whether the area being planted has or has not recently been
forested. It involves planting seedlings over an area of land where the forest has been harvested or damaged by fire
or disease or insects. Tree planting is carried out in many different parts of
the world, and strategies may differ widely across nations and regions and
among individual reforestation companies. Tree planting is grounded in forest science,
and if performed properly can result in the successful regeneration of a
deforested area. Reforestation is the commercial logging industry's answer to the large-scale
destruction of old growth
forests, but a planted forest rarely replicates the biodiversity and complexity of a natural forest.Because
trees remove carbon dioxide from the air as they grow, tree
planting can be used as a geoengineering technique to remove CO2 from
the atmosphereThursday, June 4, 2015

বাংলা বাঙালি বর্ষবরণ
বাঙালির হাজার বছরের সাংস্কৃতিক ইতিহাস ঐতিহ্য ও সর্বজনীন উৎসব বলতে বাংলা নবর্ষকেই বুঝায়। বৈশাখের শিকড় বাঙালির মূলধারায় প্রোথিত এবং অসাম্প্রদায়িক চেতনার জন্য বাংলা নববর্ষের উৎসব আজ জাতীয় উৎসবে রূপ নিয়েছে। বৈশাখী উৎসবের স্ফূরণ তৃণমূল থেকে শহর এবং হালে ভৌগলিক সীমারেখা ছাড়িয়ে বিশ্বজনীন।

Visit Keukenhof Tulips
Keukenhof is the international and independent showcase for the Dutch floricultural sector, with a special emphasis on flower bulbs. In the space of eight weeks Keukenhof shows what the Dutch floricultural sector has to offer. The park’s focus is on the 7 million spring-flowering bulbs, which allow the 100 participating companies to show their living catalogue. 500 flower growers present an enormous variety of cut flowers and pot plants at the over 20 flower shows.
Keukenhof is the platform for the Dutch floricultural sector. For the exhibitors and participants in the flower shows, we provide a superb showcase for their bulbs, flowers and plants.
That's what makes Keukenhof an excellent opportunity to network and meet business contacts. Trade events for growers are also organised regularly. Keukenhof has strong ties with all the relevant organisations in the floricultural and tourist sectors.

Feeding the world, caring for the earth
Myanmar
is an agricultural country with rice as the main staple food crop, yet rice
yields are lower than in many other Asian countries.
The membership of Myanmar in the workgroup ‘Productivity and Sustainability’ of the Irrigated Rice Research Consortium (IRRC) has enabled research and extension workers in Myanmar to benefit from the wealth of knowledge on past and ongoing activities on site-specific nutrient management (SSNM) in Asia.

feed the soil to feed the plant
People who buy organic usually cite these reasons for their
decision:
- They’re
safer. Fruits and vegetables labeled as organic are generally grown
without chemical fertilizers and pesticides. Livestock raised under
organic practices aren’t fed antibiotics or growth hormones.
- They’re
kinder to the environment. Organic farming practices are designed to be
more sustainable, emphasizing conservation and reducing pollutants.
- They’re
healthier. A few studies have suggested organic foods might be higher in
nutrients than their traditional counterparts.
Of these three reasons, the health claims for organic foods have
been the most tenuous. To investigate these claims, researchers at Stanford
University evaluated nearly 250 studies comparing the nutrients in organic vs.
traditional foods (fruits, vegetables, grains, poultry, meat, and eggs), and
the health outcomes of eating these foods.
The researchers discovered very little difference in nutritional
content, aside from slightly higher phosphorous levels in many organic foods,
and a higher omega-3 fatty acid content in organic milk and chicken.
Organic produce did have the slight edge in food safety, with
30% lower pesticide residues than conventional foods. In general, pesticide
levels in both organic and non-organic foods were within allowable safety
limits. It’s still not clear, though, just what that means to consumers’
health. “Just because these foods aren’t going over what they call an ‘acceptable
limit’ doesn’t mean they’re safe for everyone,” Dr. Hauser says. There haven’t
been enough studies evaluating pesticide exposure to confirm the health
effects, particularly in children and pregnant women, she adds.
