Rice is an essential food in many developing countries, especially in Asia. In the United States, approximately 3.3 million acres of rice is commercially produced in Arkansas, Texas, Louisiana, Mississippi, Missouri and California.
Rice is often cropped in heavy clay soils that retain water and will allow for flooded conditions. This unique production system allows land that may be unsuitable for other crops to be used in rice production. Because rice is grown under flooded conditions, special attention must be given to nitrogen fertility. Rice growers prefer urea and ammonium nitrogen sources that are more stable under these conditions and reduce losses through denitrification. Sulfur deficiencies are also of concern under continually flooded conditions.
The soil fertility management in paddy systems should favor the maintenance and buildup of organic matter and when it comes to mineral nutrition, a balanced fertilization is the key.
Phosphorus is generally applied before planting, whereas, for improved efficacy, nitrogen and potassium are applied in split applications, throughout the cropping period.
