“…Barley had the largest yield response to soil pH in comparison with wheat and triticale (Liu et al, 2004). There was found a significant positive relationship between top soil (0-10 cm) pH and yield of wheat, and top and subsoil (11-20 cm) pH and yield of barley (Flower, Crabtreec, 2011).…”

“…Triticale is grown in moderately acid and slightly acid soils (pH Cl 5.6-6.5) which was the case in our long-term experiment. Triticale is a pH tolerant species and had the least response to soil pH (Liu et al, 2004). The grain yield varied from 0.74 to 5.46 t ha -1 and depended on the rate of fertilizers (p < 0.05, r = 0.91) and rate of lime (p < 0.05).…”

The paper describes the influence of long-term (more than 30 years) fertilizer and lime application on the soil acidity (pH Cl ) and identifies the influence of soil acidity on the productivity of crops. Since 1994, a seven-year crop rotation was created: (1) winter triticale → (2) potatoes → (3) spring wheat → (4) spring oilseed rape → (5) spring barley → (6) and (7) perennial grasses (red clover, timothy), 1 st and 2 nd year of use. At the beginning of the experiment, the soil in treatments F0 and F2 was very strongly acid (pH KCl 4.7) but in treatments F1 and F3 -moderately acid (pH KCl 5.6). In limed treatments the soil acidity decreased from pH 4.8 to pH 5.8-6.0. In the following years till 1994, the soil acidity in limed treatments gradually increased (for about 0.4-0.6 pH units). After the first maintenance liming, the soil acidity reached nearly the previous highest level. Within the next twenty years, in the treatments with highest liming rate (11.40 t ha -1 CaCO 3 ) the soil acidity increased to pH 5.2. In treatments with low liming rate (2.58 t ha -1 CaCO 3 ), the soil acidity increased to pH 4.6, which was even lower than at the beginning of the experiment (pH 4.8). Without maintenance liming, the soil acidity during 20 years increased by 0.7-0.8 pH units. In the unlimed treatments, the soil acidity gradually increased from pH 4.8 to 4.4.

“…The simulated wheat yield range from S1 and S2 (0-9.5 t/ha) compared reasonably with observed wheat yield range of (0.28-6 t/ha) from multiple years (1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995) under good soil conditions (Heenan et al 1998;Liu et al 2004). The simulated Increasing nitrogen input also amplifies the variability of system performance under the same climate.…”

Quantifying the value of historical climate knowledge and climate forecasts using agricultural systems modelling

A well tested agricultural systems model was used together with 114 years of historical climate data to study the performance of a dryland wheat-fallow system as impacted by climate variations and nitrogen input levels in southeast Australia, and to investigate the value of: (1) historical climate knowledge, (2) a perfect climate forecast, and (3) various forecasts of targeted variables. The potential value of historical climate records increases exponentially with the number of years of data. In order to confidently quantify the long term optimal nitrogen application rate at the study site at least 30 years of climate data are required. For nitrogen management only, the potential value of a perfect climate forecast is about $54/ha/year with a reduction of excess nitrogen application of 20 kg N/ha/year. The value of an ENSO based forecast system is $2/ha/year. Perfect forecasting of three or six categories of growing season rainfall would have a value of $10-12/ha/year. Perfect forecasts of three or six categories of simulated crop yield would bring about $33-34/ha/year. Choosing integrated variables as a forecasting target, for example crop yield derived from agricultural modelling, has the potential to significantly increase the value of forecasts.

“…Such genotypic difference in water use from the acid subsoil could be diminished if the subsoil is dry. Third, the superior vegetative growth of the Al-tolerant Diamondbird would have depleted water in the acid subsoil more than Janz, and hence could exacerbate drought stress under the tolerant wheat (Liu et al 2004).…”

Biological amelioration of subsoil acidity through managing nitrate uptake by wheat crops

et al. 2010

Subsoil acidity occurs in many agricultural lands in the world, and is considered to be an irreversible constraint due to amelioration difficulties. This field study aimed to develop a biological method to ameliorate subsoil acidity through the rootinduced alkalisation resulting from nitrate uptake. Aluminium (Al)-tolerant wheat variety Diamondbird and Al-sensitive variety Janz (Triticum aestivum L.) were grown at two contrasting field sites with mild and severe subsurface acidity, respectively, and were supplied with either Ca(NO 3 ) 2 at the soil surface, Ca (NO 3 ) 2 at 10 cm depth or urea at 10 cm depth. Application of nitrate increased rhizosphere pH up to 0.5 units and bulk soil pH to 0.3 units, and to a depth >30 cm in the Kandosol. The placement of nitrate at 10 cm increased subsoil pH more than the surface application. Nitrate application increased nitrate concentration in soil profiles as expected, whereas urea application increased NH 4 + concentration which in turn favored acidification processes. Diamondbird generally produced more tillers and shoot biomass at anthesis but the two varieties did not differ in grain yield or rhizosphere alkalisation. Similar grain yields were achieved under supply of nitrate and urea. The results suggest that biological amelioration through managing nitrate uptake is possible as part of an integrated approach to combat subsoil acidity in farming systems.
