Beans or sweet potatoes may be planted at the sides of the bunds. Mud from the paddy fields is packed on top of the bunds surrounding the fields and against all paddy field margins to plug holes and improve the moisture seal of the field. After transplanting, water levels should be around 3 cm initially, and gradually increase to cm with increasing plant height. Pengaturan air untuk budldaya mina-padi berbeda dengan sistem sawah tanpa ikan.
Tanah untuk penyemaian tidak menggunakan tanah sawah tetapi menggunakan tanah darat yang gembur dicampur dengan kompos dengan perbandingan tanah: Reduced transpiration Reduced photosynthesis Reduced leaf budidaay expansion Leaf rolling Accelerated leaf death Spikelet sterility. Puddling may not be effective in coarse soils, whereas it is very efficient in clay soils that form cracks during the fallow period. Apabila tidak diatasi segera maka sejumlah petani di daerah tersebut, atau yang berada di saluran Rengas Bandung tidak bisa menggarap sawahnya karena tidak tersedianya air.

Meskipun di lahan sawah dapat diadakan pergiliran berbagai tanaman, namun pertanaman pokok selalu padi. Seedbeds ranfah planted in November to January; pannicles about a foot in length are pushed into the mud and bent so the rice grains lie flat on the ground. Wereng coklat Nilaparvata lugens 5. While some plaster mud on the margins of the fields, others bring bundles of five or six pannicles approximately to seedlings from the seedbeds.
Large amounts of water can be lost during soaking prior to puddling when large and deep rancab are present. The field is then flooded so the farmers can level the mud with the palms of their hands. Infiltration in the central area of a terraced paddy is mainly vertically downward, whereas flow near the bund is predominantly lateral.
This is particularly true in the tropics, where the erosivity of rainfall is very high, and where upland soils usually have poor resistance to erosion. A continuous supply of water is essential once the rice is transplanted. This will add additional pressure to draw irrigation water from some already overexploited aquifers, where the rate of water recharge is lower than the withdrawal rates. Bahasa lain Tambah interwiki.

With the aid of a government subsidy, the project was successfully completed, so that “akiochi” is no longer seen in Japan. Intermittent irrigation further reduced water inputs but at the expense of increased yield loss.
Ilustrasi bilik statis yg dipakai untuk mengukur aliran emisi gas di lahan padi sawah. Ganjur Pachydiplosis oryzae 9. Diminishing methane emissions from the rice field ecosystem was significantly beneficial to the growth of rice.
Puddling may not be effective in coarse soils, which do not have enough fine clay particles to migrate downward and fill up the cracks and pores in the plow sole. Inappropriate management of irrigation water and fertilizer N in irrigated corn has resulted in leaching of excess N from the rooting zone and contamination of groundwater and also has contributed to the increasing concentration of N2O in the atmosphere.

Also, they may not be able to have water flowing in if upstream farmers retain water in ggogo fields or let their fields dry out to prepare for harvest. Rice environments budisaya provide unique—but as yet poorly understood—ecosystem services such as the regulation of water and the preservation of aquatic and terrestrial biodiversity.
