Progress in research on site-specific nutrient management for smallholder farmers in sub-Saharan Africa
Published in Field Crops Research
• The SSNM approach was adapted for rice, maize and cassava production systems in SSA. • The SSNM approach increased yield, profitability, and nutrient use efficiency. • SSNM had 24% and 69% higher yield than the farmer practice for rice and maize. • Rice and maize yields were 11% and 4% higher in SSNM than local recommendations. • Integration with...

Co-benefits of nutrient management tailored to smallholder agriculture
Published in Global Food Security
• Meta-analysis was performed to compare SSNM with farmers' fertilizer practice (FFP). • Data are from 61 published papers across 11 countries on maize, rice and wheat. • Overall, 0.6 Mg ha−1 yield and US$ 140 ha−1 profit gains were obtained with SSNM. • These benefits were achieved using 10% less N fertilizer than FFP. • Agronomic N use efficiency...
Field-specific nutrient management using Rice Crop Manager decision support tool in Odisha, India
...
Published in Field Crops Research
The requirement of rice ( Oryza sativa L.) for fertilizer can depend on crop and soil management practices, which can vary among fields within a rice-growing area. A web-based decision support tool named Rice Crop Manager (RCM) was developed previously to calculate field-specific rates of fertilizer N, P, and K for rice in Odisha State in eastern I...
Site-Specific Nutrient Management under Rice-Based Cropping Systems in Indo-Gangetic Plains: Yield, Profit and Apparent ...
Published in Agricultural Research
High fertilizer use efficiency in rice (Oryza sativa L.)-based cropping systems in Indo-Gangetic Plains (IGP) is not achieved because farmers’ fertilizer practices (FFP) and blanket state recommendations (BSR) do not take into account the site-specific variability of nutrient availability in the soil. We evaluated the site-specific nutrient managem...
Geostatistical approach for management of soil nutrients with special emphasis on different forms of potassium consideri...
Published in Environmental Monitoring and Assessment
A large part of precision agriculture research in the developing countries is devoted towards precision nutrient management aspects. This has led to better economics and efficiency of nutrient use with off-farm advantages of environmental security. The keystone of precision nutrient management is analysis and interpretation of spatial variability o...

Published in Plant and Soil
Traditionally, crop production in sub-Saharan Africa (SSA) depends primarily on mining soil nutrients. Integrated Soil Fertility Management (ISFM) is an approach for intensifying agriculture in SSA that aims at maximizing the agronomic efficiency (AE) of applied nutrient inputs. ISFM contains the following essential components: proper fertilizer ma...
Rice-maize systems of South Asia: current status, future prospects and research priorities for nutrient management
Published in Plant and Soil
Rice (Oryza sativa L.) and maize (Zey mays) are grown in 3.5 million hectares (Mha) in Asia that includes 1.5 Mha in South Asia. These crops are grown in sequence on the same land in the same year either in double–or triple-crop systems to meet the rice demand of a rapidly expanding human population and maize demand of livestock and poultry. The ob...
