Ecological intensification (EI) of agriculture aims to optimize soil conservation, crop diversity and nutrient management. Despite growing interest in EI, its impact on soil properties, compared with conventional farming practice (FP), remains poorly understood as a result of limited field evidence. This study, conducted over eight seasons in southern Brazil as part of the ‘Global Maize Project’ of the International Plant Nutrition Institute, evaluated EI compared with FP, and FP with silage (FPS) using a split‐plot design. Four nitrogen application rates (0, 70, 140 and 210 kg ha−1) were applied to subplots with four replicates. Soil properties were measured to a depth of 1 m. The trial systems consisted of a maize–soybean rotation under no‐till during summer and cover crops and fertilizer application during winter. In the FP system, black oats and wheat were cultivated, while FPS utilized white oats and ryegrass. In the EI system, peas (without N application) and wheat were cultivated. In the 4‐years preceding the trial, the area was cultivated in a no‐till system with maize–soybean during summer and black oat–wheat in winter. Our results reveal distinct differences in soil properties among the systems, with FPS demonstrating greater soil acidity (pH of 4.4 at 0–5 cm) caused by higher N application than FP and EI systems. The lower soil pH altered soil nutrient dynamics, with decreased available Ca, Mg and K and increased Cu, Fe, Mn and Zn. Furthermore, nutrient availability varied, with EI having more inorganic N and DON at 0–40 cm compared with FP, but less in deeper soil (40–100 cm). Notably, EI system had more soil carbon (175 Mg ha−1) compared with FP (161 Mg ha−1), a relative annual increase of 1.8 Mg ha−1 year−1 over 8 years. These findings underscore the potential of EI to promote soil carbon, thereby contributing to climate change mitigation and soil health improvement.

“…Therefore, crop rotations with different species can increase diversity, such as combining crop legumes with grasses for silage production. For example, Rebonatti et al (2023) reported higher soybean production and improvements in soil fertility properties as a result of the inclusion of millet or palisade grass as a silage crop.…”

“…The concept of yield gap was likely first proposed by De Datta [13], and depicts the difference between actual and potential (maximal) yield at experimental stations. Multiple factors contribute to the yield gap worldwide, including weather variability and climate change [14], crop varieties [15,16], edaphic factors, and associated water and nutrient availability [17][18][19], pests and diseases [20,21], and other agronomic management factors, such as planting density and crop sequence over time [22][23][24], along with the combined effects of genetics, the environment, and management (G × E × M) [25]. To date, numerous studies have been conducted on crop yield differentials.…”

Achieving global food security requires an understanding of the current status and the future trends in the yield gap for cropping systems worldwide. The aim of this study was to scientifically understand the existing yield gap research, recognize the knowledge base and influential articles, and uncover key research themes and how these have evolved over the past three decades. Bibliometric methods were used to analyze articles related to the yield gap available in the largest scientific database, the Web of Science. A total of 6049 relevant articles published from 1993 to 2023 were numerically analyzed for patterns, trends, and clusters. The findings identified a few primary authors of widely cited publications. Geographically, the United States and China were the two major contributors to the publication pool, with articles from China mostly affiliated with the Chinese Academy of Sciences and China Agricultural University, while the United States had a more scattered distribution of affiliated institutions. The research on yield gaps primarily focused on biological factors, such as the effects of crop varieties, agronomic management, climate change, and soil conditions, with a limited exploration of social and economic factors. Within the auspices of the current food issues worldwide, this study provides a thorough view of the progress and key topics in crop yield gap research, contributing to the existing body of knowledge and providing guidance for researchers, policymakers, and stakeholders involved in agricultural productivity enhancement and sustainable food production. Amid the increasing trend in hunger worldwide over the past decade, we thus concluded that, by establishing appropriate benchmarks, re-prioritizing research needs, and focusing on transforming natural resources rather than inputs, the crop yield gap approach can be useful in terms of the clear inclusion of local contexts and socioeconomic constraints.
