The tank cascade system (Sinhala: එල්ලංගාව, romanized: ellaṅgāva) is an ancient irrigation system spanning the island of Sri Lanka. It is a network of thousands of small irrigation tanks (Sinhala: වැව, romanized: wewa) draining to large reservoirs that store rainwater and surface runoff for later use. They make ...
Chena is the oldest cultivation method in Sri Lanka, it goes far back as more than 5,000 years.(Before the Anuradhapura Kingdom) [1] [2] it the dry zone, the recovery of a chena plot proceeds through various stages of succession, (active chena, abandoned chena, chena re-growth, scrub with pioneer three species, scrub with secondary tree species, secondary forest, secondary forest with primary ...
This is a reddish-brown rice variety with a unique texture. It is low in carbohydrates, and rich in protein and fiber. Ma-Wee is also proven to have a 25% to 30% lower glycemic index (GI) than other common rice varieties. It is 84.5% carbohydrates, 9.4% protein, 3.6% fat, and 1.1% fiber. Ma-Wee rice is best when soaked prior to boiling.
A carbonate is a salt of carbonic acid, H 2 CO 3, [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3. The word "carbonate" may also refer to a carbonate ester , an organic compound containing the carbonate group O=C(−O−) 2 .
Carbon sequestration is part of the natural carbon cycle by which carbon is exchanged among the biosphere, pedosphere (soil), geosphere, hydrosphere, and atmosphere of Earth. [citation needed] Carbon dioxide is naturally captured from the atmosphere through biological, chemical, or physical processes, and stored in long-term reservoirs.
Agrominerals (also known as stone bread or petrol fertilizer) are minerals of importance to agriculture and horticulture industries for they can provide essential plant nutrients. [1] Some agrominerals occur naturally or can be processed to be used as alternative fertilizers or soil amendments. [1] The term agromineral was created in the 19th ...
Soil carbon is the solid carbon stored in global soils. This includes both soil organic matter and inorganic carbon as carbonate minerals. It is vital to the soil capacity in our ecosystem. Soil carbon is a carbon sink in regard to the global carbon cycle, playing a role in biogeochemistry, climate change mitigation, and constructing global ...
[255] [252] [248] To put this into perspective, 7.4% of Sri Lanka's GDP is reliant on agriculture and 30% of citizens work in this sector. [256] This means that about ⅓ of its population is dependent on this sector for jobs, making its maintenance highly crucial for the prosperity of the nation's social and economic status.
