The decrease in AMF colonization observed under a soil water content of 0.38 [cm.sup.3] [cm.sup.-3] (100% of field capacity) may have been due to the increased presence of parasites or decreased aeration caused by the water content in the soil being too high.
Assouline S, Or D (2014) The concept of field capacity revisited: defining intrinsic static and dynamic criteria for soil internal drainage dynamics.
In the control plot at Davis, available water in the 2 ft root zone reached field capacity only in December and early February, after which it steadily declined (fig.
[M.sub.1] = black polythene mulch; [M.sub.2] = rice straw mulch; [I.sub.1] = irrigation up to field capacity at 5 days interval after plant establishment (PE); [I.sub.2] = irrigation up to field capacity at 10 days interval after PE; [I.sub.3] = irrigation up to field capacity at 15 days interval after PE.
In the other aspect, the load-displacement curves in Figure 8(a) show that a thicker plate distinctly increases the stiffness, the field capacity, and the longitudinal displacement (which means an improved ductility).
The effective field capacity of M-C was calculated through the actual field data i.e.
Trinidad, Hernandez, Orozco and Upton (2002) reported that Pinus taeda species have high transpiration rates when the soil moisture is close to field capacity. Higher water consumption also occurred in September, likely as a result of resumed Pinus growth.
Comparison of the mean ([+ or -] standard error) the effects of drought stress (based on field capacity) in root and shoot length (cm) and fresh root and stem weight (gr) F.
In this method, seeds are broadcast at field capacity level (optimum soil moisture level) of soil after harvest of wheat.
In general, the optimum moisture for mineralization ranges from 65 to 100% of field capacity. Easily decomposable part of the soil organic matter undergoes quick mineralization and becomes a part of soil humus.
Soil properties: The soil was found to be loamy for the upper 1m depth with field capacity ranging from 27 to 26% for top to bottom horizons, wilting point of 10% and porosity varying from 47% for the top soil layers to 41% at 1m depth as shown in Table 1.
