Nitrous oxide mitigation potential of biochar derived from agricultural and forest biomass: Effects of feedstock composition and pyrolysis temperature. [PDF]

J Environ Qual
Abstract Biochar application to soil has been promoted to mitigate climate change by reducing greenhouse gas (GHG) emissions, yet significant uncertainty exists in quantifying soil nitrous oxide (N2O) emissions from biochar‐amended soils. We evaluated soil N2O emissions from soils amended with biochar prepared from diverse agricultural and forest ...

Linking remote sensing with crop modeling for yield and nitrate leaching predictions in Minnesota. [PDF]

J Environ Qual
Abstract Upscaling crop yield and nitrate‐N leaching loss from experimental sites to large areas under alternative crop rotations is crucial for assessing strategies and setting goals to protect groundwater quality at a regional scale. Nitrogen (N) rate field trials were used to calibrate the Environmental Policy Integrated Climate (EPIC) model for ...

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 (

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 ...

Potential Nitrogen Mineralization and Its Availability in Response to Long-Term Fertilization in a Chinese Fluvo-Aquic Soil

Agronomy, 2022
The determination of organic nitrogen (N) mineralization is crucial for estimating N availability, quantifying exogenous inputs, and estimating associated environmental impacts.

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.

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

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Soil biological quality of grassland fertilized with adjusted cattle manure slurries in comparison with organic and inorganic fertilizers [PDF]

, 2009
We studied the effect of five fertilizers (including two adjusted manure slurries) and an untreated control on soil biota and explored the effect on the ecosystem services they provided.

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.
