“…The water storage in the soil was calculated using Equation 2. The bulk density of the soil at a depth of 0-30 cm was calculated according to the measurements obtained that correlated to each year, and the water content in the soil at a depth of 30-100 cm was calculated according to the average bulk density of 1.46 g/ cm 3 of the soil. The bulk density of the soil at a depth of 30-100 cm changed a little as the depth of tillage was less than 30 cm.…”

Effects of subsoiling on maize yield and water-use efficiency in a semiarid area

et al. 2017

A 3-year field research was conducted to investigate the effect of four subsoiling methods on maize yield and water use efficiency. These four subsoiling methods included bulk subsoiling in autumn (BS), annual ridge subsoiling in autumn, annual furrow subsoiling in early summer, and interannual alternate zone subsoiling (AS), which were compared with rotary tillage in spring. The results suggested that the bulk density of the soil was alternately changed by AS, but AS had limited effect on the average water storage in the soil. Overall, soil tilled by BS and AS maintained a high water-holding capacity, which could stabilize the yield of maize under varying rainfall across different years. Maize under the AS subsoiling method maintained a relatively higher production capacity and water-use efficiency compared with those under the other three types of subsoiling methods.

“…Research is a key driver here because potential new measures of and additional arguments for subsoil management seem to be primarily discussed within the scientific community. Therein, subsoil management is discussed in terms of sequestering carbon (climate change mitigation) (Kell 2012;Alcantara et al 2016;Lorenz and Lal 2005), water conserving tillage (climate change adaptation) (Sang et al 2016), and phosphorous efficiency (resource scarcity) (Ekelöf et al 2015;Zhang et al 2016). Thus, research is now providing more arguments for subsoil management in relation to current societal challenges, thereby potentially creating a meaningful impact.…”

Global trends in demand for biomass-based food, feed, energy, and fiber call for a sustainable intensification of agricultural production. From the perspective of sustaining soil functions, this implies the integration of soil productivity with the other soil functions and services, namely carbon sequestration, water purification and retention, and nutrient and matter cycling as well as biodiversity. Soil management is the key to this integration. The proper anticipation of future opportunities and challenges for sustainable soil management requires an analysis of drivers and trends affecting soil management. Here, we review drivers and trends of soil management and their relevance for soil functions taking Germany as an example of industrialized agricultural systems with low yield gaps. We analyzed socio-economic, biophysical and technological drivers and identified two types of future management changes: (1) Quantitative changes, i.e., more or less of the same input factors, such as fertilizers, as part of a moderate intensification. (2) Qualitative changes: There, we found the strongest signals for the following practices: higher precision and lightweight machines triggered by information and communication technology (ICT) and robotics; diversification of crop rotations, including the integration of lignocellulosic crops; inoculation with biota; and new crop varieties. Positive practices may be reinforced by a behavioral trend towards sustainable soil management, driven by increasing awareness, knowledge, and consumer demand. They offer opportunities for relieving mechanical pressures from weight and contact stress, chemical pressures from pesticides and fertilizers and promoting soil biodiversity without compromising the soil's production function. We also found threats, such as increased removal of organic residues and potentially harmful organisms. This foresight study is the first to delineate opportunities and challenges for sustainable soil management and intensification. It informs researchers who intend to improve the knowledge base for reinforcement of positive and mitigation of negative trends of soil management.

“…Infiltration, one of the most important soil properties, is responsible for water entering the soil; however, it is not easy to measure and predict, as it is highly variable both spatially and temporally [3]. Some major driving forces, such as soil surface crusting due to the high kinetic energy of falling raindrops [4,5]; soil sealing on the surface or at deeper levels (e.g., plough pan [6]); and rill and gully formation, which decreases water contact to the soil surface, decrease infiltration [7], whereas other forces, such as increasing plant growth, surface roughness, and surface coverage [8], increase the volume of infiltration. Ploughing tillage (PT; conventional cultivation system based on annual moldboard ploughing tillage) plays an ambivalent role.…”

Infiltration and Soil Loss Changes during the Growing Season under Ploughing and Conservation Tillage

et al. 2017

Abstract:Decreased water retention and increased runoff and soil loss are of special importance concerning soil degradation of hilly crop fields. In this study, plots under ploughing (conventional) tillage (PT) and conservation tillage (CT; 15 years) were compared. Rainfall simulation on 6 m 2 plots was applied to determine infiltration and soil loss during the growing season. Results were compared with those measured from 1200 m 2 plots exposed to natural rainfalls in 2016. Infiltration was always higher under CT than PT, whereas the highest infiltration was measured under the cover crop condition. Infiltration under seedbed and stubble resulted in uncertainties, which suggests that natural pore formation can be more effective at improving soil drainage potential than can temporary improvements created by soil tillage operations. Soil erodibility was higher under PT for each soil status; however, the seedbed condition triggered the highest values. For CT, soil loss volume was only a function of runoff volume at both scales. Contrarily, on PT plots, some extreme precipitation events triggered extremely high soil loss owing to linear erosion, which meant no direct connection existed between the scales. Improved soil conditions due to conservation practice are more important for decreasing soil loss than the better surface conditions.
