Climate change and ensuring food security for an exponentially growing global human population are the greatest challenges future agriculture. Improved soil management practices crucial to tackle these problems by enhancing agro-ecosystem productivity, fertility, carbon sequestration. To meet Paris climate treaty pledges, must address validated approaches sequestration stabilization. The present synthesis assesses a range of current potential agricultural (AMP) that have effect on organic...

ABSTRACT Conventional tillage, including ploughing after harvest and/or for seedbed preparation, aims to incorporate crop residues and weeds loosen, mix aerate the soil. However, less beneficial effects, such as a loss of soil organic carbon (SOC), are also associated with intensive tillage. This has made reduced minimum tillage systems without increasingly popular in agriculture, contributing health climate change mitigation. We studied effects different on chemical microbial properties...

Abstract Aim of our study was the development methodological basis for characterization humic fractions a long‐term field experiment. Humic acids (HAs) were extracted from three layers nontilled soil using different extractants (1 M NaOH, 0.1 Na 4 P 2 O 7 , 1 CO 3 ), and humin fraction enriched. NaOH as extractant FTIR analysis substances yields higher resolved IR spectra, especially in important regions stretching vibrations including aromatic aliphatic groups fingerprint area amides,...

Abstract Alternative management practices such as no‐tillage compared to conventional tillage are expected recover or increase soil quality and productivity, even though all of these aspects rarely studied together. Long‐term field experiments ( LTE s) enable analysis alternative over time. This study investigated a total 251 European s in which crop rotation, catch crops, cover crops/green manure, no‐tillage, non‐inversion organic fertilization were applied. Response ratios indicators for...

The COVID-19 pandemic has disrupted the global food supply chain and exacerbated problem of nutritional insecurity. Here we outline soil strategies to strengthen local production systems, enhance their resilience, create a circular economy focused on restoration through carbon sequestration, on-farm cycling nutrients, minimizing environmental pollution, contamination food. Smart web-based geospatial decision support systems (S-DSSs) for land use planning management is useful tool sustainable...

Soil microbial growth, respiration, and carbon (C) use efficiency (CUE) are essential parameters to understand, describe model the soil cycle. While seasonal dynamics of respiration well studied, little is known about how growth CUE change over course a year, especially outside plant growing season. In this study, we measured gross via 18O incorporation into DNA, biomass in an agricultural field deciduous forest 16 times two years. We sampled soils depth 5 cm from plots at which harvest...

Soil organic matter (SOM) is indispensable for soil health and, in the context of climate change, considered a significant CO2 sink. Improving agricultural management to increase long-term carbon (SOC) stocks mitigating change requires tools that estimate short and long-cycling SOM pools. In this study, we analyzed changes fast-cycling particulate (POM) slow-cycling mineral-associated (MAOM) induced by common practices, i.e., fertilization crop rotation topsoils from 25 Central European...

In recent years, machine learning (ML) algorithms have gained substantial recognition for ecological modeling across various temporal and spatial scales. However, little evaluation has been conducted the prediction of soil organic carbon (SOC) on small data sets commonly inherent to long-term research. this context, performance ML SOC never tested against traditional process-based approaches. Here, we compare algorithms, calibrated uncalibrated models as well multiple ensembles their in...

Abstract Cover crops (CC) offer numerous benefits to agroecosystems, particularly in the realm of soil organic carbon (SOC) accrual and loss mitigation. However, uncertainties persist regarding extent which CCs, co‐occurrence with environmental factors, influence SOC responses associated C pools. We therefore performed a weighted meta‐analysis on effects CCs mineral‐associated (MAOC), particulate (POC) microbial biomass (MBC) pool compared no CC cultivation arable cropland. Our study...

Soil is the most important natural resource for life on Earth after water. Given its fundamental role in sustaining human population, both availability and quality of soil must be managed sustainably protected. To ensure sustainable management we need to understand intrinsic functional capacity different soils across Europe how it changes over time. monitoring needed support evidence-based policies incentivise management. this aim, assessed which attributes can used as potential indicators...

Remote sensing data, crop growth models, and optimization routines constitute a toolset that can be used together to map yield over large areas when access field data is limited. In this study, Leaf Area Index (LAI) from the Copernicus Sentinel-2 satellite were combined with Environmental Policy Integrated Climate (EPIC) model estimate using re-calibration assimilation approach. The experiment was implemented for winter wheat during two growing seasons (2016 2017) under four different...

Agricultural decision support systems (DSS) are mostly focused on increasing the supply of individual soil functions such as e.g. primary productivity or nutrient cycling, while neglecting other important functions, water purification and regulation, climate regulation carbon sequestration, biodiversity habitat provision. Making right management decisions for long-term sustainability is therefore challenging, farmers farm advisors would greatly benefit from an evidence-based DSS targeted...

Abstract Soil and its ecosystem functions play a societal role in securing sustainable food production while safeguarding natural resources. A functional land management framework has been proposed to optimize the agro‐environmental outputs from specifically supply demand of soil such as (a) primary productivity, (b) carbon sequestration, (c) water purification regulation, (d) biodiversity (e) nutrient cycling, for which knowledge is essential. From outset, LANDMARK multi‐actor research...
