SUMMARY Anthropogenic global change is driving an increase in the frequency and intensity of drought flood events, along with associated imbalances limitation several soil nutrients. In context increasing human population, these impacts represent a global‐scale challenge for biodiversity conservation sustainable crop production to ensure food security. Plants have evolved strategies enhance uptake nutrients under environmental stress conditions; example, symbioses fungi (mycorrhization) rhizosphere release exudates from roots. Although cultivation managed effects limited availability nitrogen (N) phosphorus (P), there evidence plant growth fitness because low other such as metals potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), which may become increasingly limiting productivity change. The roles mycorrhizas on N P been studied intensively; however, our understanding metal less clear still inconsistent. Here, we review literature role root key (N, P, K, Ca, Mg, Fe) potential nutrient deficiencies non‐crop terrestrial ecosystems, identify knowledge gaps future research improve nutrient‐uptake capacity plants.

Agroforestry potential for adaptation to climate change: A soil‐based perspective

Soil Use and Management, Journal Year: 2023, Volume and Issue: 39(3), P. 1006 - 1032

Published: June 13, 2023

Abstract Agricultural systems face several challenges that threaten their capacity to feed the world while maintaining a healthy and functional environment. Climate change, together with soil degradation, biodiversity loss, resource scarcity invasive species, is major threat agricultural worldwide. In this context, new practices have been proposed circumvent or minimize these threats. Yet, mostly focus on farm plant level (e.g., breeding for stress‐tolerant species), frequently overlooking belowground components organic carbon accrual). By interlinking above‐ below‐ground components, likelihood of limiting negative effects current threats can be maximized. This review explores knowledge regarding agroforestry its as key property in reducing climate change. We first tree properties systems. synthesize evidence response environmental are related continue by discussing how processes play fundamental role cope conclude proposing options resilience could further enhanced.

Assessing the phosphorus cycle in European agricultural soils: Looking beyond current national phosphorus budgets

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 906, P. 167143 - 167143

Phosphorus (P) is an essential nutrient for all crops, yet its excess negatively affects public health, the environment, and economy. At same time, rock P a critical raw material due to importance food production, finite geological deposits, unequal regional distribution. As consequence, management addressed by numerous environmental policies. Process-based biogeochemical models are valuable instruments monitor cycle predict effect of agricultural In this study, we upscale calibrated DayCent model at European level using data-derived soil properties, advanced input data sets, representative practices. Our results depicted budget with average surplus (0.11 kg ha-1 year-1), total (2240.0 ha-1), available content (77.4 ha-1) consistent literature national statistics. Through scenarios, revealed range potential changes in 2030 2050, influenced interlink carbon nitrogen cycles. Thus, developed powerful assessment tool capable i) identifying areas or deficit high spatial resolution 1 km2, (ii) pinpointing where change would be most urgent reach policy goals terms pollution, security resource efficiency material, iii) assessing response modifications management.
