Agricultural arts ( tle 20 )

TLE 20

Agricultural Arts


  • is the production of food and goods through farming. Agriculture was the key development that led to the rise of human civilization, with the husbandry of domesticated animals and plants (i.e. crops) creating food surpluses that enabled the development of more densely populated and stratified societies. The study of agriculture is known as agricultural science. Agriculture is also observed in certain species of ant and termite

Organic pesticide

  • is an organic chemical, meaning that the molecule consists mainly of a carbon skeleton plus other elements such as hydrogen, oxygen, nitrogen, sulfur, phosphorus or chlorine. By this definition, nearly all pesticides are organic, while only a few are inorganic, such as copper sulfate, cryolite, lead arsenate, Mercurochrome chloride and phosphine. A pesticide that is claimed to be environmentally friendly. By this definition, very few pesticides are organic. Claims that a pesticide is environmentally friendly should be viewed with scepticism.

Bokashi products

  • being used increasingly to create powerful natural fertilizers and compost for home garden, reducing agricultural effluent on farms, reducing landfill footprints in remote, inaccessible places.

  • Reduce organic waste in volume

  • Enhance soil condition

  • Reduce smelly odors

  • Speed up the rate of decomposition

  • Enable organic matter to be reused to promote the growth of other plants and animals

Inorganic pesticides

  • do not contain carbon as part of their chemical composition. These compounds usually have relatively low molecular weights and often contain less than 10 atoms. Several inorganic salts (often white and crystalline) are classified in this category of pesticides. A few inorganic pesticides have been used for more than 1000 years but their use increased dramatically from 1850 to 1950. The popularity of many inorganic pesticides declined after the development of more effective and less persistent organic pesticides.

Lemon grass, Cymbopogon citratus

  • is an unusual tropical grass as an essential flavoring in South East Asian cooking. Its bright lemony scent is used in drinks, curries and soups. It is delicious in tea with cloves. It’s rich in vitamin A. Its oil also has many industrial and medicinal uses.

Grow in a frost

  • free place in full sun or light shade. The herb likes moist, well-drained soil that is slightly acidic. It grows best in warm, humid conditions. It can also be grown in a container or in the greenhouse. If you move your plant outdoors for the summer, allow it to acclimatize over a number of days, first placing it in shade, then moving it to part shade before giving it full sun.

Lemon grass Cultivation

  • The plant can be grown from seed or division. The many varieties available, mostly used in commercial cultivation, do not come true from seed, and seeds germinate slowly, so vegetative propagation is usually preferred. Lift and cut apart clumps in early spring or fall. Space 3 feet apart. Lemon grass is clump forming and does not runner and become invasive like some grasses. Water regularly in summer.
