“…Ash measurements were assayed in triplicate for each plot in 2009. Similar to Verkler et al (2008), volumetric soil water content profiles were measured throughout the experimental period from May 2009 to February 2011 using CS616 water content reflectometers (WCR [Campbell Scientific, Inc., Logan, UT]). Each sensor consisted of two stainless steel rods 0.3-m long and 3.2 mm in diameter with 0.03-m spacing between the two rods.…”

Switchgrass Growth and Effects on Biomass Accumulation, Moisture Content, and Nutrient Removal

Temporal patterns of plant growth, composition, and nutrient removal impact development of models for predicting optimal switchgrass (Panicum virgatum L.) harvest times for bioenergy. Original time-course data are needed to construct useful models. Objectives were to characterize seasonal trends in yield, tissue moisture, ash content, leaf area index (LAI), interception of photosynthetically active radiation (PAR), and macronutrient accumulation and losses. Plots were subjected to 12 single harvests

“…Several authors have addressed the greater soil water storage and lower runoff in NT for different crops (Blevins et al, 1990;De Vita et al, 2007;Almaraz et al, 2009;Stipesevic and Kladivko 2005;Verkler et al, 2008). Tormena et al (2002) and Klein and Libardi (2002) identified properties that increase water storage under NT when compared with CT for different soils and crops.…”

“…Tormena et al (2002) and Klein and Libardi (2002) identified properties that increase water storage under NT when compared with CT for different soils and crops. Verkler et al (2008) conducted experiments on soybean crop using both NT and CT systems, recording soil water content values over a two year period (2005 and 2006) to a depth of 0.075m in the delta of the Mississippi River, in the United States. Despite little difference in soil water storage between the two tillage systems in this layer, the soil dries slower under NT and continues with higher water content, allowing for water to be available for longer periods of time.…”

“…In addition, CI under NT was greater than under CT at either residue level at the 0.4-m depth. Because tillage was not expected to have had any direct effect at this depth, differences in CI between burn treatments might be caused by deeper rooting and greater root decomposition rates and moisture contents under burning than nonburning (Verkler et al, 2008).…”

Improving long-term agricultural sustainability requires appropriate soil and residue management practices. Soil cone index (CI), which relates to the resistance to penetration of a cone of specific dimensions, is an important physical property relating to soil and crop productivity, particularly in intensive cropping systems. A study was initiated in 2001 to evaluate the effect of alternative residue management practices on soil penetration resistance in a wheat (Triticum aestivum L.)-soybean (Glycine max [L.] Merr.) double-cropped system in the Mississippi River Delta region of eastern Arkansas. Residue management treatments consisted of tillage (conventional tillage and no-tillage [NT]), residue burning (burn and no burn), and residue level (low and high, achieved by differential N fertilization). Soil CI, as measured using a hand-pushed penetrometer, was determined at 0.05-m intervals to a depth of 0.4 m in 2003, after one, and in 2006, after four complete cropping cycles. The whole-field CI increased with depth in both years. Tillage, burning, and residue level generally did not affect CI in the top 0.20-m in either year. In both years, soil CI was consistently lower under burning than nonburning at all depths below 0.20 m. Compared with after only 1 year, 4 years of NT soybean resulted in a 35% increase in CI at the 0.05-m depth. Soil CI was reduced at the 0.4-m depth under NT and nonburning but increased somewhat under conventional tillage and nonburning after 4 years. Being aware of the potential effects of alternative residue management on soil properties and root growth in relation to soil penetration resistance will be necessary for sustainable soil management practices.
