Fertilizer recommendations (FR) to improve yields and increase profitability are based on
relationships between crop yields and soil nutrient levels measured via soil extraction …

Massive changes have taken place in the nutrient management of Australian crops and
pastures in the past three decades. Before then the supply of nutrients had been mostly from …

In Africa, the need to have high resolution soil maps cannot be overstated as the continent
has over 33 million farmers owning less than 2 ha plots, who represent 80% of all farms and …

Potassium (K) is a crucial element for plant nutrition and its availability and spatial
distribution in agricultural soils is influenced by many agro-environmental factors. In …

There are many terms used to define aspects of potassium (K) use efficiency of plants. The
terms used most frequently in an agricultural context are (1) agronomic K use efficiency …

Balancing nutrient inputs and exports is essential to maintaining soil fertility in rainfed crop
and pasture farming systems. Soil nutrient balances of land used for crop and pasture …

Abstract The Fertilizer Recommendation Support Tool (FRST) will perform correlations
between soil nutrient concentrations and crop response to fertilization from user‐selected …

Soil testing is the most widely used tool to predict the need for fertiliser phosphorus (P)
application to crops. This study examined factors affecting critical soil P concentrations and …

This article aims to discuss the arcsine–log calibration curve (ALCC) method designed for
the Better Fertiliser Decisions for Crop** Systems (BFDC) to calibrate relationships …

Globally, 12 million hectares of agricultural soil are lost to degradation each year. Australia
