Better Fertilizer Decisions for Crops

Project summary and access to the data interrogator

2013 Annual Interpretive Summary - Wheat and Lupin Potassium Responses

The Better Fertilizer Decisions for Crops project identified gaps in the dataset for wheat and canola responses to K in eastern Australia. This project will support additional soil measurements of sel ...

Developing Multi-Variate Management Zones for Corn Production

This project intends to evaluate the benefit of multi-variate management zones and develop strategies which can account for the temporal and spacial variability seen in crop nutrient requirements.

Salinity Mapping for Precision Variable Rate Fertilizer Application

The incidence of salinity affected areas in irrigated fields results in restricted crop growth in the saline areas. If fertilizer applications are a constant rate blanket application over the field, t ...

Potassium response curves - Wheat and Lupin Potassium Responses

The Better Fertilizer Decisions for Crops Project (BFDC) that concluded in 2012 identified several gaps in data around the development of robust soil test calibrations. This project seeks to collect c ...

2012 Annual Interpretive Summary - Improvement of Recommendations for Potash Fertilizer Use and Adjustment of Currently Used Soil Potassium Test Interpretation Classes in Intensive Cropping Systems

During the last 15 years in Russia, both nutrient use (rates) and ratios have changed with a larger decline in the share of P and K fertilizers relative to N fertilizer. The adjustment of nutrient rat ...

Project Description - Improvement of Recommendations for Potash Fertilizer Use and Adjustment of Currently Used Soil Potassium Test Interpretation Classes in Intensive Cropping Systems

During the last 15 years in Russia, both nutrient rates and ratios were changed with a decline in the relative share of phosphate and potash fertilizers relative to N fertilizer. The adjustment of nut ...

2012 Annual Interpretive Summary - Evaluation of the Potassium Status of Arable Soils in Ukraine on the Basis of Modern Soil Diagnostic Techniques and Development of Recommendations for the Rational and Efficient Application of Potassium Fertilizers.
