The study aimed to observe the effects of two forage sorghum hybrids and different nitrogenous (N) fertilizer rates. current was set up in randomized complete block (RCB) as a split-plot design with triplicate at Field Crops Department experimental area, University Ankara 2022 summer season. This experiment included treatments which had (Hay day Super-graze) nitrogen fertilization rates form 18...

A Bulgarian project at Maritsa East power station demonstrated the proper transformation of air pollutants (SOx and NOx) into nitrogen fertilizer. Although this technology has not been put into practice in Bulgaria, it seems feasible on an industrial scale and so it may help to ease Portugal’s reliance on imports of nitrogen fertilizer and thereby contain the outfl ow of Portuguese funds. The d...

Abstract The purpose of this study was to evaluate the effects furrow fertigation on nitrate deep leaching, runoff losses, and plant nitrogen supply in various growth stages maize ( Zea mays L.). Furrow experiment conducted 120 (W1), 100 (W2), 80 (W3), 60% (W4) levels required water (560 mm) (N1), (N2), 60 (N3), 0% (N4) fertilizer (184 kg N ha −1 ). N-fertilizer applied four split applications ...

Increased fertilizer input in agricultural systems during the last few decades has resulted in large yield increases, but also in environmental problems. We used data from published papers and a soil testing and fertilization project in Shaanxi province during the years 2005 to 2009 to analyze chemical fertilizer inputs and yields of wheat (Triticum aestivum L.) and maize (Zea mays L.) on the f...

Farmers in developing countries sometimes receive incorrect and misleading information regarding the fertilizer inputs into food production, especially during crises or times of unusually high demand. In the early 2000’s farmers of Thailand were sold fake fertilizer or advised to apply excessive amounts of fertilizers by fertilizer dealers. The problem was so pervasive that a protocol was devel...

Little information exists on the potential for N fertilizer application to corn ( L.) to affect NO emissions during subsequent unfertilized crops in a rotation. To determine if N fertilizer application to corn affects NO emissions during subsequent crops in rotation, we measured NO emissions for 3 yr (2011-2013) in an Iowa, corn-soybean [ (L.) Merr.] rotation with three N fertilizer rates appli...

Chemical composition of soil organic carbon (SOC) is central to soil fertility. We hypothesize that change in SOC content resulting from various long-term fertilization strategies accompanies the shift in SOC chemical structure. This study examined the effect of fertilization strategies along with the time of fertilizer application on the SOC composition by 13C nuclear magnetic resonance (NMR) ...

Synthetic nitrogen (N) fertilizer has played a key role in enhancing food production and keeping half of the world's population adequately fed. However, decades of N fertilizer overuse in many parts of the world have contributed to soil, water, and air pollution; reducing excessive N losses and emissions is a central environmental challenge in the 21st century. China's participation is essentia...
