Soil‐nitrogen, potentially mineralizable‐nitrogen, and field condition information marginally improves corn nitrogen management

Agronomy Journal, 2020
AbstractAnaerobic potentially mineralizable nitrogen (PMN) combined with preplant nitrate test (PPNT) or pre‐sidedress nitrate test (PSNT) may improve corn (Zea mays L.) N management. Forty‐nine corn N response studies were conducted across the U.S. Midwest to evaluate the capacity of PPNT and PSNT to predict grain yield, N uptake, and economic optimal

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 ...

Modelling microbial exchanges between forms of soil nitrogen in contrasting ecosystems [PDF]

, 2014
Although nitrogen (N) is often combined with carbon (C) in organic molecules, C passes from the air to the soil through plant photosynthesis, whereas N passes from the soil to plants through a chain of microbial conversions.

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

IMPACT OF POTENTIALLY SOIL MINERALIZABLE NITROGEN (PMN) ON SOIL HEALTH AND CROP PRODUCTION

Biological and Agricultural Sciences Research Journal, 2023
Potentially Soil Mineralizable Nitrogen (PMN) is critical in soil health and crop production. This review paper explores the impact of PMN on soil health, crop production, different soil types, and mitigation strategies. It highlights the importance of PMN in enhancing nutrient availability, crop yield, and quality.

Comparison of indices for the prediction of nitrogen mineralization after destruction of managed grassland [PDF]

, 2010
Intensively managed grasslands are occasionally chemically killed with herbicide and ploughed in order to grow an arable crop. After this management, large N mineralization rates with large losses to the environment are commonly observed.
