Intensive crop production on grassland-derived Mollisols has liberated massive amounts of carbon (C) to the atmosphere. Whether minimizing soil disturbance, diversifying rotations, or re-establishing perennial grasslands and integrating livestock can slow reverse this trend remains highly uncertain. We investigated how these management practices affected organic (SOC) accrual distribution between particulate (POM) mineral-associated (MAOM) matter in a 29-y-old field experiment North Central...
Integrated crop-livestock systems (ICLS) are designed to exploit synergisms and emergent properties resulting from interactions between different soil-plant-animal-atmosphere compartments that integrate themselves at spatial-temporal scales. In this review, a panorama of the evolution studies based on ICLS is presented. Specific keywords were used as search terms construct database 450 articles 93 national international journals published up including 2013. These classified according region...
Abstract. Soil organic and inorganic phosphorus (P) compounds can be influenced by distinctive environmental properties. This study aims to analyze soil P composition in natural ecosystems, relating (inositol hexakisphosphate, DNA phosphonates) (orthophosphate, polyphosphate pyrophosphate) with major temporal (weathering), edaphic climatic characteristics. A dataset including 88 sites was assembled from published papers that determined using one-dimensional liquid state 31P nuclear magnetic...
Growing multiple crops in rotation can increase the sustainability of agricultural systems and reduce risks from increasingly adverse weather. However, widespread adoption diverse rotations is limited by economic uncertainty, lack incentives, information about long-term outcomes. Here, we combined 36,000 yield observations 20 North American cropping experiments (434 site-years) to assess how greater crop diversity impacts productivity complete their component under varying growing...
Abstract Soil fertility under no‐tillage farming may be affected by agricultural complexity. By transforming most of the ingested pasture into urine and faeces, ruminants catalyse nutrient cycling breaking down complex plant molecules, which can help to maintain or even improve soil fertility. We evaluated how integrating annual crops ruminant grazing cover in same land area at overlapping times affect systems. chemical properties were 0–5‐cm 5–25‐cm depths, three long‐term cropping...
There is insufficient evidence for how cover crop-driven changes to the soil microbial community affect organic carbon (SOC) accumulation. One mechanism by which enhanced activity can contribute SOC accrual through conversion of plant inputs biomass and ultimately necromass that may form organo–mineral associations with particles. Here we investigated effects winter rye as a crop harvested forage double on SOC, chemically labile complex C fractions, biomarkers (amino sugars), potential...
Abstract The number of co‐added scans and spectral resolution are two fundamental acquisition parameters in diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). However, systematic studies evaluating these soil science applications lacking, especially when using mid‐infrared frequencies (mid‐DRIFTS). objective this study was to evaluate how numbers affect both qualitative predictive high‐throughput mid‐DRIFTS soils. We first explored the literature with a review better...
Abstract. Subsoil carbon (C) stocks are a prime target for efforts to increase soil C storage climate change mitigation. However, subsoil dynamics not well understood, especially in soils under long-term intensive agricultural management. We compared and organic matter (SOM) composition tomato–corn rotations after 25 years of differing nutrient management the California Central Valley: CONV (mineral fertilizer), CONV+WCC fertilizer cover crops), ORG (composted poultry manure crops). The crop...
Core Ideas Near‐infrared spectroscopy (NIRS) was appropriate for predicting soil texture and C. Both linear nonlinear multivariate models could be used NIRS calibration. Soil predicted with greater precision than organic C fractions. kriging were a useful combination assessing spatial variation. geostatistics are relatively unexplored tools that reduce the time, labor, costs of analysis. Our objective to efficiently determine lateral vertical distributions (SOC) fractions in an agroforestry...
Abstract There is an increased interest in using diffuse reflectance infrared Fourier transform spectroscopy the mid‐infrared region (mid‐DRIFTS) for high‐throughput prediction of soil properties, but basic methodological factors toward this end have yet to be thoroughly vetted. This study aimed determine how combined effects grinding (sieved <2.0 mm and finely ground <0.5 mm) sample replication (single or multiple subsamples, one‐to‐four replicates) affect spectral quality predictive...
Abstract Fostering and maintaining soil health via holistic management is a central goal for most organic farmers. However, many questions remain regarding how different practices influence in farm fields. In this study, we used mail‐in survey to assess such as crop diversity, perennials rotation, tillage, manure use, subscription cation balancing biochemical indicators certified corn ( Zea mays L.) Organic farmers n = 195) from the eastern Corn Belt mailed along with completed research lab...
Abstract Soil test phosphorus (P) and potassium (K) the associated soil critical values (CSTVs) are widely used as primary diagnostic tool to determine if a crop needs P K fertilizer. However, identifying robust predictive CSTVs requires large number of field trials in representative soils environments assess fertilizer responses. From 1976 2021, total 457 458 were conducted corn ( Zea mays ), soybean Glycine max wheat Triticum aestivum ) across 40 counties Ohio. The consisted both...
Core Ideas Total, mineral‐associated, and mineralizable C fractions varied along a soil texture gradient. Specific surface area Fe oxyhydroxides were positively associated with clay concentration. Soil oxides. Aluminum oxide was not related to concentration or specific area. Mineralizable had the most complex relationship is known affect organic (SOC) microbial activity, but these relationships are always straightforward. We characterized total, gradient of within flood plain field in...
In oat production, tillering persistence is the determinant of one important yield component, namely number panicles. This process highly influenced by inter- and intraspecific interactions agroecosystem, which in turn depend on agronomic practices. The hypothesis this research that nitrogen does not increase tolerance to negative interference from trees, so grain production remains un-modified at distances relative eucalyptus tracks, within alley cropping agroforestry system (ACS). Thus,...
Diffuse reflectance spectroscopy has been extensively employed to deliver timely and cost-effective predictions of a number soil properties. However, although several spectral laboratories have established worldwide, the distinct characteristics instruments operations still hamper further integration interoperability across mid-infrared (MIR) libraries. In this study, we conducted large-scale ring trial experiment understand lab-to-lab variability multiple MIR instruments. By developing...
