Researchers on-site to inspect a set of nutrient omission plots (NOTs) for wheat growing in Minjar Shenkora District, in the Amhara region of Ethiopia. The plots evaluated the effect of omitting nitrogen, phosphorus, potassium, and micronutrients on wheat growth and yield, against a plot receiving a balanced application of all nutrients. **Photo by Dr. Samuel Njoroge**

Share your Snapshots: Honouring a Century-Old Tree

APNI’s scientists alongside researchers from the Tunisian Olive Institute (OIT) assessed biomass accumulation of this century-old olive tree to determine its capacity to partition nutrients and sequester carbon.

Ask an APNI Expert: Can we estimate the fertility status of soil without knowing the plant nutrient status?

In short, the answer is yes, you can estimate the fertility status of soil without knowing the plant nutrient status. Traditionally this can be done through soil analysis, which provides an index of the plant availability of soil nutrients through a standardized test from a lab. Other soil tests can assess properties such as soil pH, cation exchange capacity, and organic matter content, which all contribute to the soil’s potential to supply the right balance of nutrients at rates that meet the demands of a productive crop.
