Nitrogen Fertilizer Application in Grass–Clover Elevated Nitrate Leaching in the Follow‐on Maize Crop

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Grass–clover and silage maize are key for dairy feed production and frequently occur within the same crop rotations. Fertilizer management in grass–clover may leave residual effects that influence both environmental outcomes and the performance of subsequent maize crops.

Phosphorus fractions affected by lime and green manure application in Nitisols of Banja district, northwestern Ethiopia

Discover Soil
Low phosphorus (P) availability due to its fixation by iron and aluminum oxides is one of the critical constraints for crop production in acidic soils. Understanding its transformation following application of different amendments is therefore important ...

The Residual Effects of Organic and Chemical Fertilizer of Spring Crop (Black Cumin) To Production of Pea (Pisum sativum) Green Manure [PDF]

Journal of Agricultural Science and Sustainable Production, 2016
In sustainable agriculture, efficient use of the nutrients residues of fertilizers had superior importance to production of green manure. In order to utilize the organic and chemical fertilizer residue in black cumin (Nigella sativa L.) crop to green ...

Nine-year results on maize and processing tomato cultivation in an organic and in a conventional low input cropping system

Italian Journal of Agronomy, 2013
Nine-year results on yields and apparent balances of organic matter and nitrogen (N) are reported for maize and processing tomato cultivated in a long term comparison trial between an organic and a conventional low-input system in Central Italy. In every

Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Infrared Spectroscopic Predictions of Soil Properties for Agricultural Monitoring: Statistical and Soil Spectroscopic Considerations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Pseudo‐independent validation (PIV) using regional datasets is common in visible‐to‐near‐infrared (vis–NIR) and mid‐infrared (MIR) spectroscopy studies and produces accurate predictions but is relevant only to regional‐scale monitoring of known sites.

Recent advances in soil carbon sequestration and emission reduction within legume green manure enhanced rotation systems: a review

Journal of Agriculture and Food Research
Prolonged intensive agricultural practices have caused substantial losses of soil carbon and nitrogen pools, contributing to soil degradation and increased greenhouse gas emissions, thereby posing significant threats to agricultural sustainability.

Perspectives of High‐Resolution Mass Spectrometry in Soil Science

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

Journal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...
