Nitrogen, Volume 6, Issue 1

The development of critical levels for sap nitrate and chlorophyll meter reading (SPAD test) in the case of various crops is of great importance for growers in characterizing a plant’s N status. A field experiment with spring oat (Avena sativa...

Excessive irrigation in protected vegetable production often results in soil nutrient loss and groundwater contamination. Cucumber (Cucumis sativus L.) is a widely cultivated and important vegetable in the world and a sensitive plant to irrigation wa...

An experiment was conducted in spring 2024 to investigate the effects of biochar, biogas slurry, and dicyandiamide (DCD) on N2O emissions from soil in protected tomato cultivation. Five treatments were applied: conventional fertilization (CK1), bioga...

Nitrogen, an essential element for plant growth and food production, presents significant challenges in agriculture due to the environmental consequences of synthetic nitrogen fertilizers. This review explores the potential of nitrogen-fixing cyanoba...

The use of nitrification inhibitors (NIs) with nitrogen fertilizers represents an effective strategy to reduce nitrogen loss. In addition, nitrification inhibitors are widely applied to improve agricultural yield. However, it is necessary to continue...

Nitrous oxide (N2O) is a potent greenhouse gas, and agriculture represents more than fifty percent of total anthropogenic emissions. The production of N2O in soil is biogenic through nitrification, denitrification, chemonitrification, nitrifier denit...

Nitrogen (N) deficiency in soil limits the development of forage grasses, while its application can significantly increase productivity. This study aimed to evaluate the effects of increasing N doses and cutting intervals on structural and productive...

Bark beetle-associated bacteria from the sub-boreal and boreal forests of northern Canada represent a largely unexplored source of bioactive natural products. This study aims to investigate the chemical potential of bacteria isolated from Dendroctonu...

The hybrid progeny (1-1) resulting from the cross between Caucasian clover and white clover initially demonstrated an inability to fix nitrogen naturally via spontaneous nodulation. However, following inoculation with specific rhizobia strains derive...

Nitrogen fertilization greatly affects the development of sugar beet leaf and photosynthetic activity. This study aimed to evaluate the dynamics of leaf SPAD index, chlorophyll a (Chl a), chlorophyll b (Chl b), carotenoids (Caro), and the macron...
