The Effects of Manure and Nitrogen Fertilizer Applications on Soil Organic Carbon and Nitrogen in a High-Input Cropping System
With the goal of improving N fertilizer management to maximize soil organic carbon (SOC) storage and minimize N losses in high-intensity cropping system, a 6-years greenhouse vegetable experiment was conducted from 2004 to 2010 in Shouguang, northern China. Treatment tested the effects of organic manure and N fertilizer on SOC, total N (TN) pool and annual apparent N losses. The results demonst...
متن کاملGreenhouse gas emissions from two soils receiving nitrogen fertilizer and swine manure slurry.
The interactive effects of soil texture and type of N fertility (i.e., manure vs. commercial N fertilizer) on N(2)O and CH(4) emissions have not been well established. This study was conducted to assess the impact of soil type and N fertility on greenhouse gas fluxes (N(2)O, CH(4), and CO(2)) from the soil surface. The soils used were a sandy loam (789 g kg(-1) sand and 138 g kg(-1) clay) and a...

span of years also greatly affects C and N dynamics. Wood et al. (1990) measured greater potentially minerCycling of N through an agroecosystem can be managed more alizable C and N in surface soils of a wheat–corn–millet– effectively if effects of N management and cropping sequence on soil fallow (WCMF), 4-yr rotation than a WF, 2-yr rotation. N microbial processes are understood. Effects of cr...
متن کاملMineralization of Manure Nutrients
In order to apply manure or compost to fulfill the nutrient requirements of a crop, knowledge of the amount of nutrients mineralized following application is needed. Nutrient mineralization from applied manure depends on temperature, soil moisture, soil properties, manure characteristics, and microbial activity. Since these factors cannot be accurately predicted, nutrient mineralization from ap...
متن کاملAgro- physiological responses of Carthamus tinctorius L. to sources of nitrogen fertilizer and organic manure
Excessive consumption of nitrogen (N) to enhance production, which may lead to environmental pollution. While sustainable production is threatened due to low soil fertility and organic matter. This study was carried out as a factorial experiment in the randomized complete block design and three replications at the research field of the University of Jiroft in 2018-2019. The present study invest...
