mbc by Zixin Lu — last modified May 18, 2015 01:38 PM
Microbial biomass carbon (MBC) for three different depths in soil and for No-Till, Continuous Cropping (NTCC), No-Till, Fallow (NTF), Standard Till, Continuous Cropping (STCC) and Standard Till, Fallow (STF). Nematode populations for the four systems are shown as well (Minoshima, 2007).

Ammonium, nitrate concentrations and ammonium oxiding bacteria (AOB) populations were measured after ammonium was applied to Russell Ranch field soils. The solid line represents plots with ammonium treatment and the dashed line represents plots with no ammonium (Okano et al., 2004).

tillage-irrigation by Zixin Lu — last modified May 18, 2015 02:00 PM
The effect of irrigation (furrow vs. drip), tillage (standard vs. conservation) and weed control (herbicides vs. none) on tomato yields (Sutton, 2006).

Effect of cover crops and no-tillage practice on dissolved organic carbon export during a 2-day pre-irrigation in 400 and 1200 ft long fields under standard tillage (ST), standard tillage after cover crop incorporation (CC), and no-tillage (NT) (Burger et al. 2008).

n20 by Zixin Lu — last modified May 20, 2015 11:54 AM
Nitrous oxide emissions by growing season (May to Sept) and the rainy season (Oct to April). WLCC= winter legume cover crop (vetch and pea mix), NCC= no cover crop, FI= furrow irrigation, SDI= subsurface drip irrigation (Kallenbach, 2008).
n-emissions by Zixin Lu — last modified May 20, 2015 12:05 PM
Effects of cropping management on nitrous oxide emissions. The nitrous oxide emissions paired with a star were significantly higher among the cropping systems. Graph from Kong, 2007.
burger-n by Zixin Lu — last modified May 20, 2015 12:19 PM
Total denitrification after irrigation or simulated rainfall. The organic system had cover crop and manure incorporated in the spring and had high ammonium content at the April sampling. Both systems were sprinker irrigated in October to simulate rainfall and the conventional system had ammonium nitrate applied five days before sampling. Graph from Burger, 2005.

Figure 1: Map of a one acre plot with microplots identified. Researchers can modify conditions in the microplots, while leaving the central yield measuring area untouched for long-term data collection.
