Herbicide resistance has become an important constraint on modern
agricultural practices. An alarming increase in weed biotypes that
are resistant to herbicides has also been reported. Opportunity
exists for a novel weed management technology, which is also
compatible with no-till agricultural practices. Microwave heating
can kill both emerged weed plants and weed seeds in the soil. When
the intensity of the microwave fields is moderate, plants, which
have already emerged, are susceptible to microwave treatment. If
the microwave field is intense enough, very rapid volumetric
heating and some thermal runaway in the plant structures cause
micro-steam explosions in the plant cells, which rupture the plant
structures, leading to death. Soil treatment requires significantly
more energy; however, there are secondary benefits for crops
growing in microwave treated soil. These include: significant
reduction of the dormant weed seed bank; significant reduction of
nematode populations; significant reduction of fungal populations;
better availability of indigenous nitrogen for the plants; more
rapid humification; and significant increases in crop growth and
yield. Microwave weed management and soil treatment is not
restricted by weather conditions; therefore, the technology may
offer some timeliness and environmental benefits, which are yet to
be quantified in a cropping system.
Many people hesitate to address problems in their lives for fear of
change. But doing nothing leads to a dead end. The Billiard
Strategy will show you how to take action to reach your goals.
Vielen Menschen fallt es schwer, trotz offensichtlicher Probleme

Sie sich den richtigen Anstoss geben Mit einfachen Worten und ohne
viel Theorie beschreibt der Autor, was ihm selbst uber Jahrzehnte
geholfen hat. Darin liegt die Starke der Billard-Strategie: Sie ist
erprobt und verspricht dem Leser nichts, was sie nicht auch halten
kann. Wer sie verinnerlicht, fuhrt ein glucklicheres Leben
