Abstract Redesigning agrosystems to include more ecological regulations can help feed a growing human population, preserve soils for future productivity, limit dependency on synthetic fertilizers, and reduce agriculture contribution global changes such as eutrophication warming. However, guidelines redesigning cropping systems from natural make them sustainable remain limited. Synthetizing the knowledge biogeochemical cycles in ecosystems, we outline four that synchronize supply of soluble nutrients by soil biota with fluctuating nutrient demand plants. This synchrony limits deficiencies excesses nutrients, which usually penalize both production regulating services retention carbon storage. In outlined, emerges plant–soil plant–plant interactions, eco‐physiological processes, physicochemical dynamics various reservoirs, including organic matter, minerals, atmosphere, common market. We discuss relative importance these depending pedoclimatic context functional diversity plants microbes. offer ideas about how could be stimulated within improve their sustainability. A review latest advances agronomy shows some practices suggested promote (e.g., reduced tillage, rotation perennial plant cover, crop diversification) have already been tested shown effective reducing losses, fertilizer use, N 2 O emissions and/or improving biomass Our framework also highlights new management strategies defines conditions success nature‐based allowing site‐specific modifications. synthetized should practitioners long‐term productivity while negative impact environment climate.

Physical soil organic matter (SOM) fractions provide increased insight into the biogeochemical functioning of soils. Several fractionation methodologies have been developed to separate particulate (POM) from mineral-associated (MAOM) either by particle size, density, or some combination these two properties. The proliferation approaches separation has led ambiguity regarding what methodologically defined should be understood conceptually represent, hindering robust data synthesis analyses and model development. Here we attempt identify chemical similarities differences amongst POM MAOM separated different physical approaches, with aim guiding choices for future research. We obtained soils 11 farms across United States variable parent materials, textures, pHs, fractionated them using 4 methods. tested single-step methods: a size (53 µm cutoff) density (1.85 g cm−3 cutoff), multi-step combined after full dispersion, which isolates third pool associated coarse, heavy particles (coarse matter; CHAOM), method delayed dispersion free occluded + CHAOM fraction. analyzed all C N concentrations, their isotopic composition, composition via mid-infrared spectroscopy. found that tended very homogenous in character regardless schemes, while varied widely. In particular, isolated floatation was distinct both spectroscopic signature compared alone. Indeed, our results indicated is composite fraction light CHAOM, does not map well onto conceptual pool. more similar terms indicating one-step separations may most effective means isolating contrasting SOM pools time cost-efficient matter. However, analysis highlights POM, exhibit features, three are worth separating size-density when possible.

Abstract A regional geopolitical conflict and sudden massive supply disruptions have revealed vulnerabilities in our global fuel–fertilizer–food nexus. As nitrogen (N) fertilizer price spikes threaten food security, differentiated responses are required to maintain staple cereal yields across over- underfertilized agricultural systems. Through integrated management of organic inorganic N sources high- low-input production systems, we estimate potential total N-fertilizer savings 11% India, 49% Ethiopia 44% Malawi. Shifting more cost-effective, high-N (such as urea), combined with compost integration legumes, can optimize N-deficient Better targeted efficient use will benefit systems surplus N. Geospatially fertilization strategies should prioritize low-yield, locations balanced N, P, K micronutrients high-yield Nationally, governments invest extension realign subsidies enable incentivize improved at the farm level.

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 conditions. Maize soybean output increased as number species length increased, while results for varied site depending on which were present. Diverse reduced rotation-level at eight sites due addition lower-output such small grains, illustrating trade-offs. positively impacted poor conditions, illustrates risk loss a changing climate.

Introduction Understanding how nutrient inputs affect nitrogen (N) transformations and storage is vital for developing sustainable agroecosystems. Organic N inputs, such as crop residues (e.g., cover biomass stover) animal manures, can accelerate cycling by increasing mineralization immobilization rates to provide crops with more opportunities intercept it moves through bioavailable pools. We aimed understand organic synthetic soil amendments inhibit or promote mineralization, immobilization, nitrification rates. Methods conducted a meta-analysis of peer-reviewed studies assess transformation in Specifically, we targeted employing 15 pool dilution methods quantify response amendments. Results discussion Our findings indicate that adding synthetic, manure, derived increased 60%, 135%, 214%, respectively, relative the unamended controls. While manure residue produced similar rates, induced significantly higher than – sevenfold fourfold increase, respectively. Furthermore, only enhanced ammonium (NH 4 + ) size, while resulted no change NH size. These results suggest encourage tighter coupling carbon (C) cycles compared delivering C rich substrates C:N ratio >20:1) microbes. This leads faster mineralization-immobilization processes larger pools those observed As such, recycling between inorganic forms, which crucial supporting needs throughout growing season minimizing losses.
