Despite ample rainfall, some Cambodian farmers in Oddar Meanchey Province have not been able to plant rice due to the high price of fertilizer and pesticides.
The prices of commonly used fertilizer and herbicides had significantly increased in the past two years causing heavy losses to farmers, according to a farmer.
Cambodia imported 103,005 tons of pesticides and 1,406,775 tons of fertilizers in 2021.

Mitigating greenhouse gas emissions from irrigated rice cultivation through improved fertilizer and water management
Annually, Bangladesh consumes about 2.9 million metric tons of urea and about 60% of this is used in rice cultivation. Therefore, this could contribute to increasing atmospheric pollution due to increased CH4 and N2O emissions. Increasing nitrogen-use efficiency by adopting urea deep placement (UDP) could reduce environmental pollution including mitigation of GHG emissions compared to conventional nitrogen management through broadcasting method or the adoption of an integrated plant nutrient system. Moreover, UDP could be more effective in mitigating greenhouse gas emissions when it is combined with alternate wetting and drying irrigation.
New fertilizer strategies combining manure and urea for improved rice growth in Mozambique
The use of integrated fertilization combining mineral and organic fertilizers has a strong potential and could be available and affordable for smallholder rice producers. An advantage of the application of organic wastes as fertilizer is that they usually provide nutritive elements to crops at little added cost along with the addition of organic matter to enrich the soil.
Weeds and their responses to management efforts in a changing climate
Climate change is likely to have huge impacts on the problematic weeds and their management. Therefore, continuous research is needed to formulate new management strategies to combat them. However, along with climate change, socio-economic, technological, and geopolitical changes will also take place in the 21st century that will likely affect the environment and agricultural systems (including weed management) and our ability to sustain crop productivity.
