In intensively irrigated rice cultivation, plant-available silicon (Si) is a crucial nutrient for improving rice productivity. As a source of Si, calcium silicate (CaSiO3) was amended to evaluate the effect of silicate fertilizer on rice production,

Biochar, a carbon (C) rich material produced from biomass, is an inexpensive means of removing C from the atmosphere by incorporating it into the soil, where C sinks are formed for sequestration. The slow release of carbon dioxide (CO2) from the soil

Rice fields are considered as one of the major sources of methane (CH 4 ), and they also emit nitrous oxide (N 2 O). A field experiment was conducted at the International Rice Research Institute, Philippines, in 2010–2011 using a temperature free-a
