Integrated Nutrient Management

Aims of an efficient and cost-effective nutrient management

• Maximize nutrient uptake of crops through good crop management practices.
• Fully utilize nutrients regardless of source
• Use mineral fertilizers as required to overcome specific nutrient limitations

A COST-EFFECTIVE AND EFFICIENT NUTRIENT MANAGEMENT

Minimize risk of crop failure by:

• Selecting realistic and economic yield targets
• Practicing efficient use of fertilizer
• Balanced nutrition by adding organic fertilizers

Maximize revenue by:

• Considering cost of inputs

RICE STRAW MANAGEMENT

• Straw is the only organic material available in significant quantities to most rice farmers.
• Incorporating rice straw and stubble returns most of the nutrients taken up by rice plants and helps to conserve soil nutrient reserves in the long term
• Early, dry shallow tillage at 5 to 10 cm depths (to incorporate crop residues and enhance soil aeration during fallow periods) has beneficial effects on soil fertility in intensive rice-rice systems.
• Shallow tillage of dry soil should be carried out up to 2-3 weeks after harvest in cropping systems where the dry-moist fallow period between two crops is at least 30 days.
