Soil compaction caused by vehicular traffic adversely affects key soil functions and ecosystem services that soils provide. Although is a well-recognized problem, it remains challenging to quantify the economic ecological costs of compaction. The mechanization in agriculture has resulted steady increase weight farm vehicles. It reasonable assume this exacerbated compaction, but there little quantitative knowledge on development levels arable soils. To these trends, we use historical records...
Soil compaction constitutes a major threat to the fertility of arable soils and food security. The aim this paper is highlight need opportunities for plant eco-physiological approaches identify strategies recover crop yields after soil compaction. Reduced productivity on compacted primarily results from decreased root elongation rates thus limited accessibility water nutrients. Hence, must address phenomena that underlie low system expansion rates. In soil, growth due high penetration...
Soil health reflects the capacity of a soil to provide ecosystem services. A major challenge management is support agricultural productivity without jeopardizing other However, there relatively little knowledge on how affects in real farm settings. This study investigated impact indicators 20 fields southern Sweden. In addition, we collected samples from an adjacent unmanaged at each field, representing potential site. was quantified by measuring physical and biological indicators: wet...
Increased soil strength due to compaction or drying is a major limitation root growth and crop productivity. Roots need exert higher penetration force, resulting in increased stress when elongating soils of greater strength. This study aimed quantify how the genotypic diversity tip geometry diameter influences elongation under different levels determine extent which roots adjust Fourteen wheat (
Core Ideas We provide long‐term data on soil structure evolution following compaction. Treatments with and without plants tillage are included. Monitoring includes physical biological properties crop measures. Compaction decreased fluid transport capability increased mechanical impedance. The projected intensification of agriculture to meet food targets a rapidly growing world population likely accentuate already acute problems compaction deteriorating in many regions the world. key role for...
X-ray computed tomography (CT) has become a powerful tool for root phenotyping. Compared to rather classical, destructive methods, CT encompasses various advantages. In pot experiments the growth and development of same individual can be followed over time in addition unaltered configuration 3D system architecture (RSA) interacting with real field soil matrix studied. Yet, throughput, which is essential more widespread application basic research or breeding programs, suffers from bottleneck...
Root growth requires substantial amounts of energy and thus carbohydrates. The costs root are particularly high in both dry compacted soil, due to soil penetration resistance. Consequently, more carbon must be allocated from aboveground plant tissue roots, which limits crop productivity. In this study, we tested the utility cortical cell diameter as a potential selection target reduce growth. Isothermal calorimetry was adopted for situ quantification 16 wheat (Triticum aestivum) genotypes...
Soil compaction of arable land, caused by heavy machinery constitutes a major threat to agricultural soils in industrialized countries. The degradation soil structure due leads decreased (macro-) porosity resulting increased mechanical impedance, which adversely affects root growth and crop productivity. New cultivars, with systems that are adapted conditions strength, needed overcome the limiting effects on plant growth. This study aimed i) quantify genetic diversity early system...
Soil compaction includes a set of underlying stresses that limit root growth such as increased impedance and limited oxygen availability. The aims the present study were to (i) find acclimations triticale (× Triticosecale) soybean (Glycine max L.) roots compacted soils in field; (ii) reproduce these under controlled conditions; (iii) associate responses with soil physical properties. To this end, plants grown at two different bulk densities field conditions representing mature systems...
Abstract Soil compaction affects many soil functions, but we have little information on the resistance and resilience of microorganisms to this disturbance. Here, present data response microbial diversity a single event its temporal evolution under different agricultural management systems during four growing seasons. Crop yield was reduced (up −90%) in first two seasons after compaction, mostly recovered subsequent increased bulk density (+15%), decreased air permeability (−94%) gas...
Abstract Soil compaction by farm machinery may persist for decades, hampering soil productivity and functioning. Assessing costs guiding recovery strategies are hindered paucity of data on structure rates. A long‐term Structure Observatory was established a loamy in Switzerland to monitor after prescribed compaction, better assess the roles natural processes (vegetation, macrofauna, shrink–swell cycles) patterns. The aim this study quantify short‐term under conditions presence absence plant...
The use of heavy farm machinery has resulted in widespread soil compaction many regions the world. Compacted limits access crops to water and nutrients is expected reduce crop productivity, but influence weather conditions on interactions between compacted productivity unclear. Furthermore, early vigor been regarded as a promising trait for improving yield grown under edaphic stress such compaction. We aimed assess combined effects contrasting growth grain spring wheat, evaluate association...
Abstract One of the critical challenges in agriculture is enhancing yield without compromising its foundation, a healthy environment and, particularly, soils. Hence, there an urgent need to identify management practices that simultaneously support soil health and production help achieve environmentally sound systems. To investigate how influences under realistic agronomic conditions, we conducted on‐farm study involving 60 wheat fields managed conventionally, no‐till or organically. We...
Microbial carbon-use efficiency (CUE) in soils captures carbon (C) partitioning between anabolic biosynthesis of microbial metabolites and catabolic C emissions (i.e. respiratory waste). The use for provides a potential the accumulation metabolic residues soil. Recognised as crucial control cycling, CUE is implemented majority soil models. Due to models' high sensitivity CUE, reliable projections demand accurate quantifications. Current measurements neglect non-growth metabolites, such...
Abstract. Drought poses increasing challenges to global food production. Knowledge about the influence of drought on crop development and role soil properties for severity is important in risk analysis mitigating impacts at landscape level. Here, we tested if satellite images from Sentinel-2 could be used assess responses scale what were. As a case study, assessed winter wheat growth 13 fields belonging commercial farmers southern Sweden dry year (2018) with normal weather conditions (2021)....
Soils store significant amounts of carbon (C) and thus can play a critical role for mitigating climate change. Crop roots represent the main C source in agricultural soils are particularly important long-term storage agroecosystems. To evaluate potential different farming systems to contribute soil sequestration change mitigation, it is great importance gain better understanding factors influencing root allocation distribution. So far, still unclear how varies among whether choice management...
Abstract Modern crop production is characterized by high nitrogen (N) application rates, which can influence the co-limitation of harvested yield other nutrients. Using a multidimensional niche volume concept and scaling exponents frequently applied in plant ecological research, we report that increased N phosphorus (P) uptake growing wheat along with enhanced grain biomass associated more than proportional increase Furthermore, conversion efficiency are strongly affected magnesium (Mg) to P...
Nitrogen (N) is considered quantitatively most important for crop growth and productivity. The improvement of N use efficiency economically beneficial to farmers reduces the negative environmental impact agriculture. Root traits are promising, yet underexploited breeding targets improve efficiency. We aimed evaluate (1) effects genotype environment on various root architectural anatomical traits; (2) relationships between traits, uptake conversion Nine spring wheat genotypes were grown...
