Effect of calcium silicate on nutrient use of lowland rice and greenhouse gas emission from a paddy soil under alternating wetting and drying

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, nitrogen (N) use efficiency, and greenhouse gas (G...
