The practice is beneficial as it yields harvests of both rice and ducks. The two are in addition synergistic, as the rice benefits from being weeded and fertilized by the ducks, and having pests removed, while the ducks benefit from the food available in the rice paddy fields, including weeds and small animals.
Paddy fields are a common sight in the Philippines. Several vast paddy fields exist in the provinces of Ifugao, Nueva Ecija, Isabela, Cagayan, Bulacan, Quezon, and other provinces. Nueva Ecija is considered the main rice growing province of the Philippines. [citation needed] The Banaue Rice Terraces are an example of paddy fields in the country.

Puddling is the tillage of rice paddies while flooded, an ancient practice that is used to prepare for rice cultivation. Historically, this has been accomplished by dragging a weighted harrow across a flooded paddy field behind a buffalo or ox, and is now accomplished using mechanized approaches, often using a two-wheel tractor.
No-till is the practice of never tilling a field. Tilling every other year is called rotational tillage. The effects of tillage can include soil compaction ; loss of organic matter ; degradation of soil aggregates ; death or disruption of soil microbes and other organisms including mycorrhizae , arthropods , and earthworms ; [ 9 ] and soil ...
The term “upland rice” refers to rice cultivated in non-flooded conditions, and it can encompass various specific definitions. While most of the world's rice is grown in paddy fields or wet environments that require significant amount of water, rice itself does not inherently need flooding to thrive.
Agriculture in Singapore is a small industry, composing about 0.5% of the total GDP, within the city-state of Singapore. Singapore's reliance on imports for about 90% of its food underscores the paramount importance of food security. To address this, Singapore has set a goal to produce 30% of its nutritional needs locally by 2030. [1]
To put this into practice, channels are added in the previously flat rice fields to allow the fish to continue growing even during rice harvest and dry seasons. [3] [9] Before creating the rice field, the field is treated with 4.5–5.25 tonnes per hectare (2.0–2.3 short ton/acre) of organic manure. [3]
