Keep detailed records – they are essential for good nutrient management. Monitoring of nutrient applications, crop performance and other relevant factors (such as weather patterns) facilitates decision making with respect to the efficiency offertiliser use. It allows nutrition programs to be fine-tuned and any environmental impacts associated with fertiliser use to be minimised.
It is important that the following information be recorded.
- Details of fertiliser application (including location of the block/s fertilised, date of application, type and quantity of fertiliser used, the method of application and by whom, etc.).
- Information on soil condition and characteristics.
- Results of nutrient analyses (such as soil and tissue/sap testing).
- Crop type, variety, planting date and harvesting date.
- Crop performance and quality measurements.
- Crop health and nutritional disorders.
Detailed records provide vital information on production and environmental management, which is important for crop performance, market access and sustainability.
