Nitrogen release from organic N sources is controlled by the soil environment. Soil incubation was conducted to evaluate the effects of soil moisture (50, 70, and 90% of water holding capacity) and temperature (15/10, 20/15, and 25/20°C [14/10 h]) on N release from four organic N sources. Differential N release kinetics of the N sources were determined by measuring ammonium- and nitrate-N contents periodically over 12 wk. Net N released, as a percentage of organic N, was greatest in the order…

Nitrogen Release from Slow-Release Fertilizers as Affected by Soil Type and Temperature

Loss of N from fertilized agricultural soils is a serious problem that can negatively affect environmental quality. Nitrogen loss can be moderated by using slow-release fertilizer (SRF) products

Effects of temperature and amendments on nitrogen mineralization in selected Australian soils

This study posits the following implications: (1) inorganic fertilizer accumulate high NO3 content in soils in a short period of incubation, thereby becoming a potential source of NO3 leaching; (2) organic N sources can serve as possible source of nitrifying bacteria, thereby increasing bioavailable N (NO3) in soils regardless of the soil properties and temperature.

Soil Moisture and Temperature Effects on Nitrogen Mineralization in a High Tunnel Farming System

ABSTRACT Effects of temperature and moisture on nitrogen (N) mineralization from organic amendments in high tunnel farming systems are rarely studied to assist N fertilizer management for high

Effects of Moisture Level on Nitrogen Availability in Tropical Peat Soil Cultivated with Oil Palm (Elaeis guineensis Jacq.)

Nitrogen release from soil is controlled by the soil moisture. Soil incubation was conducted to evaluate the effect of different moisture condition (75 %, 100 % and 150 %) on water holding capacity

Nitrogen Mineralization in Soils Related to Initial Extractable Organic Nitrogen: Effect of Temperature and Time

An important source of nitrogen (N) for crops is mineralization of soil organic matter during the growing season. Awareness is growing that dissolved organic nitrogen (DON) plays an important role in

Mineralization of Three Organic Manures Used as Nitrogen Source in a Soil Incubated under Laboratory Conditions

Abstract The rate and timing of manure application when used as nitrogen (N) fertilizer depend on N‐releasing capacity (mineralization) of manures. A soil incubation study was undertaken to establish

Effects of Soil Properties and Nitrogen Fertilization on Distribution of NO3-N in Soils of Eastern Poland

The effects of anthropogenic (nitrogen fertilization) and natural [soil texture, pH content of humus, ammonium nitrogen (N-NH4), and the available forms of phosphorus (P), potassium (K), magnesium

Quantifying soil water effects on nitrogen mineralization from soil organic matter and from fresh crop residues

Abstract. A loamy sand was incubated with and without addition of carrot leaves at six different water contents ranging from 6% to 20% (g 100 g–1 dry soil) and N mineralization was monitored during

Nitrogen fertilizers promote denitrification

Abstract A laboratory study was conducted to compare the effects of different N fertilizers on emission of N2 and N2O during denitrification of NO3– in waterlogged soil. Field-moist samples of

Temperature Effects on Kinetics of Microbial Respiration and Net Nitrogen and Sulfur Mineralization

Global climate change may impact the cycling of C, N, and S in forest ecosystems because increased soil temperatures could alter rates of microbially mediated processes. We studied the effects of

Nitrogen and phosphorus mineralization potentials of soils receiving repeated annual cattle manure applications

Abstract. Manure application rates are generally calculated to balance nutrient inputs with crop requirements, based on a projected crop yield and estimates of nutrient release from recently applied

Soil temperature, matric potential, and the kinetics of microbial respiration and nitrogen mineralization

Soil temperature and matric potential influence the physiological activity of soil microorganisms. Changes in precipitation and temperature can alter microbial activity in soil, rates of organic

Soil water effects on the use of heat units to predict crop residue carbon and nitrogen mineralization

Soil heat units (degree days) have previously been shown to predict net N mineralization from crop residues and papermil sludge. The present study was designed to identity the effects of soil water
