Does potentially mineralizable nitrogen predict maize yield in newly cropped soil? [PDF]
Agrosystems, Geosciences & Environment, 2020 Fallow soils converted to crop use have unpredictable soil organic nitrogen (SON) availability during the growing season, which incentivizes over‐applying fertilizer N by way of compensation.

Predicting Economic Optimal Nitrogen Rate with the Anaerobic Potentially Mineralizable Nitrogen Test [PDF]
Agronomy Journal, 2019 Estimates of mineralizable N with the anaerobic potentially mineralizable N (PMNan) test could improve predictions of corn (Zea mays L.) economic optimal N rate (EONR). A study across eight US midwestern states was conducted to quantify the predictability of EONR for single and split N applications by PMNan.

Potentially mineralizable nitrogen in West African lowland rice soils [PDF]
Geoderma, 1997 Abstract Nitrogen (N) deficiency is a major constraint to rice production in West Africa. Little information is available on the N supplying capacity of soils used for wetland rice production in West Africa. Potentially mineralizable N, as a measure of N supplying capacity, was determined employing an anaerobic incubation test in 15 diverse soils ...

Soil sample timing, nitrogen fertilization, and incubation length influence anaerobic potentially mineralizable nitrogen [PDF]
Soil Science Society of America Journal, 2020 Abstract Understanding the variables that affect the anaerobic potentially mineralizable N (PMN an ) test should lead to a standard procedure of sample collection and incubation length, improving PMN an as a tool in corn (

United States Midwest Soil and Weather Conditions Influence Anaerobic Potentially Mineralizable Nitrogen [PDF]
Soil Science Society of America Journal, 2019 Nitrogen provided to crops through mineralization is an important factor in N management guidelines. Understanding of the interactive effects of soil and weather conditions on N mineralization needs to be improved. Relationships between anaerobic potentially mineralizable N (PMN

A Simple and Rapid Method to Evaluate Potentially Mineralizable Nitrogen in Sewage Sludge Amended Calcareous Soils [PDF]
آب و فاضلاب, 2005 Potentially mineralizable nitrogen (PMN) can be usually considered as labile nitrogen. Measurement of PMN is expensive and time consuming; therefore, a simpler and more rapid alternative may facilitate routine laboratory analysis.

Exploring Overwintered Cover Crops as a Soil Management Tool in Upper-midwest High Tunnels
HortScience, 2022 High tunnels are an important season extension tool for horticultural production in cold climates, however maintaining soil health in these intensively managed spaces is challenging. Cover crops are an attractive management tool to address issues such as

A SINGLE MEASUREMENT TO PREDICT POTENTIAL MINERALIZABLE NITROGEN [PDF]
Communications in Soil Science and Plant Analysis, 2002 Since the early 1970's, soil nitrate nitrogen (NO3-N) levels have been used as a basis for N fertilizer recommendations in western Canada. However, soil nitrate N does not represent the supplying power of soil N for plant uptake. Furthermore, the nitrate concentration in soil changes depending on the time and ambient conditions at sampling. Researchers
