Recent Papers on Water Reuse in Irrigation and Agriculture
The long-term goal of this research is to develop the infra-technologies to reclaim effluents from wastewater treatment plants and reuse them for agricultural water demands. The objectives of this were: 1) to study the effects of various wastewater treatment levels on crop growth and yields; 2) to determine the pollution loads from wastewater ...

Microalgal oil production for use in rice farms in Albufera (València) region
In the Albufera (València) region of Spain, rice has been farmed for nearly 500 years. Post-harvest flooding of rice fields has become an integral element of wetland refuge for migratory birds. The steady rise in the cost of purchased inputs is causing considerable economic stress to the viability of rice farming in this region. In 2011, it has been estimated the cost of purchased diesel ...

Competitive interactions between cultivated and red rice as a function of recent and projected increases in atmospheric carbon dioxide
Because wild lines of the same species often represent a weedy constraint to cultivated crops in the field, any differential response to atmospheric carbon dioxide concentration, [CO2], may alter weed–crop competition and seed yield. We evaluated the growth and reproduction of cultivated rice (Oryza sativa L.; Clearfield, CL161) and red or weedy rice (Stuttgart, StgS) in monoculture, and at two ...

Uptake and distribution of Iodine in Rice plants
Rice (Oryza sativa L.) plants were cultivated in an experimental field and separated at harvest into different components, including polished rice, rice bran, hull, straw, and root. The contents of iodine in these components and the soil were determined by inductively coupled plasma–mass spectrometry and radiochemical neutron activation analysis, respectively. Iodine content varied by more than ...

Fertilization management of paddy fields in Piedmont (NW Italy) and its effects on the soil and water quality
The fertilization management of the rice crop in Piedmont was analyzed at a regional scale, and the agronomic and environmental sustainability of the actual fertilization strategy of rice was evaluated through the analysis of its effect on the soils and waters quality. On average, a total amount of 127 kg ha − 1 of N, 67 kg ha − 1 of P 2 O 5 and 161 kg ha − 1 of K 2 O were ...
