Net mineralizable soil phosphorus cannot be measured by non‐isotopic approaches

Agricultural & Environmental Letters
While radioisotopic pool dilution is widely regarded as the most reliable method for estimating soil phosphorus mineralization (Pmin), high costs, low throughput, and safety requirements limit its use.

Changes in Soil Labile Organic Matter as Affected by 50 Years of Fertilization with Increasing Amounts of Nitrogen

Agronomy, 2021
Microbially mediated soil organic matter is an extremely sensitive pool that indicates subtle changes in the quality parameters responsible for the soil’s ecological and productive functions.

Extending Cover Crop Benefits with Zone Till Management in Northern Organic Summer Squash Production

Agronomy, 2021
Winter annual legume cover crops often fail to reach full maturity by spring vegetable planting dates in northern climates, which prevents maximum nitrogen (N) contributions.

Cropping systems with perennial vegetation and livestock integration promote soil health

Agricultural & Environmental Letters, 2023
Soil health can differ across cropping systems because of variation in edaphic and management factors. We evaluated how biological indicators of soil health (soil organic matter [SOM], permanganate oxidizable carbon [POXC], mineralizable carbon [MinC ...

Long term conservation agriculture impact on soil nitrogen fractions and wheat (Triticum aestivum) yield in subtropical Inceptisol

The Indian Journal of Agricultural Sciences, 2023
The present study was carried out at ICAR-Indian Agricultural Research Institute (IARI), New Delhi over two consecutive years (2020 and 2021) to evaluate the influence of conservation agriculture (CA) and nitrogen management strategies on wheat yield in

Evaluation of Alkaline Hydrolyzable Organic Nitrogen as an Index of Nitrogen Mineralization Potential of Some Coastal Savannah Soils of Ghana

Nitrogen, 2022
Numerous biological and chemical methods have been proposed over the years for estimating the nitrogen (N) mineralization capacity of soils; however, none of them has found general use in soil fertility testing.

Incubation methods for assessing mineralizable nitrogen in soils under sugarcane

Revista Brasileira de Ciência do Solo, 2013
Considering nitrogen mineralization (N) of soil organic matter is a key aspect for the efficient management of N fertilizers in agricultural systems. Long-term aerobic incubation is the standard technique for calibrating the chemical extraction methods ...

Estimates of Potentially Mineralizable Soil Nitrogen Based on Short‐Term Incubations [PDF]

Soil Science Society of America Journal, 1974
Abstract Nitrogen mineralization potentials were determined for a large number of soils by a method involving determination of N mineralized after several consecutive incubations at 35C under optimum soil water conditions. The determination of N mineralization potential, N o
