Advantage is that they save on the cost of labor planting. Disadvantages are (a) this requires more seeds, (b) grasses and weeds can grow simultaneously with the young rice plants, and (c) more difficult to remove weeds later that compete for soil nutrients and sunlight for the crops.
Below, this is outside the farm. Another rice field in front of the house of Nong Endring's son, Danny, who also helps in the farm. The women in the photo (with umbrellas) are uprooting the young rice, bundle them, to be transported to nearby rice fields for planting with equal spaces in between them.
Another side, just beside Danny's house. The south west monsoon (aka "Habagat") has resulted in nine days and nights of almost continuous rains in western Pangasinan-Zambales and nearby provinces.
The daily rains have actually continued until about middle of this week. This road has become a mini-canal for more than a week
Another set of rice fields, near our farm. Lots of water.
A mama carabao and her few months old kid. A few farmers still use farm animals to till the soil. This is non-costly of course but work is slow. One hand tractor can do work of perhaps 5 carabaos.
Above are among the sights that I enjoy whenever I visit the farm.
