Effects of Increased Nitrogen Deposition and Precipitation on Seed and Seedling Production of Potentilla tanacetifolia in a Temperate Steppe Ecosystem
Increased Nitrogen Deposition Precipitation Seed and Seedling Production of Potentilla tanacetifolia Temperate Steppe Ecosystem
2015/2/5
Background: The responses of plant seeds and seedlings to changing atmospheric nitrogen (N) deposition and precipitation regimes determine plant population dynamics and community composition under glo...
Spatial and temporal effects of nitrogen addition on root life span of Leymus chinensis in a typical steppe of Inner Mongolia
Leymus chinensis N addition root longevity root survival soil layers spatial and temporal effect
2015/2/5
To understand root dynamics of the native, perennial clonal grass Leymus chinensis in Inner Mongolia steppe, we examined spatial and temporal effects of N addition on root survivorship and longevity t...
Seasonally dependent impacts of grazing on soil nitrogen mineralization and linkages to ecosystem functioning in Inner Mongolia grassland
Typical steppe Grazing intensity Season Soil inorganic N pools Net N mineralization Soil temperature and moisture BiomassN content Nitrogen use efficiency
2015/2/4
Previous studies have suggested grazing may alter nitrogen (N) cycling of grasslands by accelerating or decelerating soil net N mineralization. The important mechanisms controlling these fluxes remain...
Comparing physiological responses of two dominant grass species to nitrogen addition in Xilin River Basin of China
Light response curve Photosynthetic characteristics δ13C Nitrogen use efficiency (NUE) Leymus chinensis Stipa grandis
2015/2/4
The two dominant species, Leymus chinensis and Stipa grandis have different distribution area in the Xilin River Basin:relatively wet and fertile for L. chinensis and dryer and leaner for S. grandis. ...
Changes in carbon and nitrogen of Chernozem soil along a cultivation chronosequence in a semi-arid grassland
Changes in carbon nitrogen of Chernozem soil cultivation chronosequence semi-arid grassland
2015/2/4
Changes in the carbon (C) stock of grassland soil in response to land use change will increase atmospheric CO2, and consequently affect the climate. In this study we investigated the effects of land u...
The Effect of Nitrogen Fertilization to the Sward on Guineagrass (Panicum maximum Jacq cv. Gatton) Silage Fermentation
Guinea Grass Silage Nitrogen Fertilizer Nitrate Nitrogen
2016/5/6
To investigate the effect of nitrogen fertilization on the quality of tropical grass silage, guinea grass grown with 3 types of nitrogen fertilizers, namely, urea, ammonium sulfate, and compound ferti...
Interactive Effects of Nitrogen and Potassium Fertilization on Oxalate Content in Napiergrass (Pennisetum purpureum)
Napiergrass Oxalate Accumulation Fertilization Nitrogen Potassium
2016/5/4
Ingestion of forage containing a large quantity of soluble oxalate can result in calcium deficiency and even death of livestock. Fertilization is one of the most practical and effective ways to improv...
Effect of Nitrogen Fertilization on Oxalate Content in Rhodesgrass, Guineagrass and Sudangrass
Nitrogen Fertilization Oxalate Content Dry Matter Yield Nitrogen Concentration
2016/4/27
An experiment was conducted to evaluate the effects of nitrogen (N) level on the dry matter (DM) yield, N concentration and oxalate content of some tropical grasses, namely Rhodesgrass (Chloris gayana...
Achieving a Nitrogen Balance for Japanese Domestic Livestock Waste: Testing the Scenario of Planting Feed Grain in Land Left Fallow
Nitrogen Balance Livestock Barley Manure Overload Groundwater Land Left Fallow for Past Year
2016/4/15
In this study, we assess the recent changes in the amount of excretion by the livestock industry, and discuss the effects of increasing the ratio of cultivated land on the reduction of surplus nitroge...
Voluntary Intake, Digestibility and Nitrogen Balance in Spotted Deer (Cervus nippon) Fed Forest By-product Silage, Oak Leaf Hay and Commercial Mixed Ration
Spotted Deer Intake Digestibility Nitrogen Balance Forest By-product Silage
2016/4/13
Forest by-product silage (FPS) comprised of foliage, shrubs, and wild grasses was prepared to examine feeding value as sole roughage source for spotted (sika) deer. This diet was compared with importe...
