Soil degradation is one of the main problems in agricultural production and leads to decreases soil quality productivity. Improper farming practices speed this process are therefore not conducive food security. The North China Plain (NCP) a key area that greatly influences security China. To explore effects different tillage measures on aggregate-associated organic carbon (AOC), accumulation transport dry matter, maize yield, identify most suitable method for use NCP, field experiment was...
We conducted field experiments since 2006 to determine the effect of tillage practices and rate nitrogen fertilization on soil properties crop yield. Four five N rates were used. The results showed that year-round total yield wheat maize under harrow (HT) rotary (RT) was not significantly different from conventional (CT, moldboard tillage) but higher than no-tillage (NT). Reduced (HT RT) with straw returned (157.5 kg/ha for 202.5 maize) suitable increase adjust carbon situation winter...
Demand for food security and the current global warming situation make high strict demands on North China Plain both production inhibition of agricultural carbon emissions. To explore most effective way to decrease soil CO2 emissions maintain grain yield, studies were conducted during 2012 2013 summer maize growing seasons assess effects wheat straw mulching yield by adding 0 0.6 kg m(-2) fields with plant densities 100,000, 75,000, 55,000 plants ha(-1). The study indicated that had some...
This paper presents results of a field study the influence tillage and weed on vertical distribution microclimate in upper, middle, deeper layers winter wheat population grain yield during 2008-2009 2009-2010 growing seasons. The showed that canopy was different among layers. Illumination higher upper layer than middle layers; under no-tillage + weed-reserving, greater difference found 3 In layer, illumination highest lowest weed-control conventional weed-control, respectively. air...
Summary Plastic film (PF) mulching is widely applied in agriculture to improve water-use efficiency (WUE) and crop production. However, without efficient recovery, the residual plastic fragments arable land threaten soil health food security. Degradable films are generally considered as alternatives conventional PF mitigate pollution. A 2-year field experiment was conducted 2016 2017 evaluate effects of various treatments (conventional mulching, transparent degradable (TDF) black (BDF) no...
This study was conducted to quantify the potential for CO2 fixation in above-ground biomass of summer maize (Zea mays L.) under different tillage and residue retention treatments. The treatments were paired included conventional with straw removed (CT0), retained (CTS), no-till (NT0), (NTS), subsoiling (SS0), (SSS). results indicated that NTS SSS can enhance translocation photosynthates grains during post-anthesis stage. showed highest total production (average 7.8 Mg ha-1), carbon...
To investigate the effects of different sources organic matter on soil biochemical properties and crop productivity to find best substitute for cow manure in fields, a field experiment was carried out wheat-maize cropping system during 2012-2015. Three types fertilizer applications, including mineral (CK), straw (S) biogas slurry (B) were compared with (M) under an equal dose nitrogen. In 0-20 cm layer, total nitrogen, microbial biomass nitrogen carbon content M treatment highest, equivalent...
Reducing CO2 emissions from agricultural soils is a key component of the overall carbon reduction strategy. The closed chamber method was used to continuously monitor concentration in soil profiles winter wheat-summer maize rotation fields North China Plain (NCP) during 2015–2017. Additionally, we evaluated contribution different tillage methods (Rotary (RT), Subsoiling (SS), No- (ZT), and conventional (CT) combination with Straw return (s) straw removal (0)) reducing emission. results...
A laboratory incubation experiment was conducted to assess the impact of straw input on CO2-C emissions. After winter wheat (Triticum aestivum L.) growing season, soil samples were collected from 0-20 cm layer. The a brown loam soil, classified as Udoll according U. S. taxonomy. Treatment levels consisted three tillage practices: sub-soiling (ST), no-till (NT) and conventional (CT), two management (with without straw), temperature (25, 30 35 °C), moisture regimes (55%, 65% 75% field capacity...
Food security and carbon emissions are major challenges for China the international community. To investigate effects of different subsoiling depths on summer maize grain yield soil emissions, in 2016 2018, three tillage treatments, that is, rotary at depth 15 cm (R15), 40 (S40), 35 (S35), were set before winter wheat sowing. The treatments analyzed. results showed compared with R15, increased microbial biomass 20–40 layers, improved respiration rate CO2-C cumulative emissions. was by...
