Objective: Analyze the contemporary scientific contributions of the Masters and Doctorate Graduate Program in Tropical Agroecosystems (PTA) taught at the Colegio de Postgraduados, Campus Veracruz, facing the current challenges of Mexican agriculture. Design/methodology/approach: A bibliographic search was carried out in SCOPUS and Web of Science, on papers (N = 92) published during 2014-2019 by PTA research-professors. A textual analysis was carried out using Nvivo Software to identify the scientific contributions, based on problematic categories suggested by FAO for Mexico. Results: Scientific contributions are more prolific in relation to the increment of agricultural productivity (66 %), to a lesser extent in sustainable practices (14.9 %), articulation of public policies (10.6%), and initiating in adaptation and mitigation of climate risks (8.5 %). Limitations of the study/implications: Findings excluded publications not indexed in SCOPUS or Web of Science or out of the analyzed period. Findings/conclusions: The PTA shows social relevance in the generation of knowledge, with scientific contributions to the current challenges of Mexican agriculture. However, they have mainly focused on increasing agricultural productivity; this does not allow the achievement of the challenges of the PTA towards research processes aimed at trans discipline. This suggests a new research role that approach disciplinary interfaces.

“…Soil water content is one of the main limiting factors for forest production, and reasonable irrigation can improve the efficiency of fertilizer utilization [15], while excessive water use may lead to a large amount of leaching of soil nutrients [16,17]. Yu et al found that a large amount of total nitrogen and total phosphorus were lost from bare and agricultural land when rainfall was less than 60 mm [18].…”

Irrigation and nitrogen application directly affect the availability and distribution of soil nutrients. Understanding the response of soil nutrients to long-term water–fertilizer coupling conditions is helpful to improve the management and use efficiency. Irrigation was divided into three gradient levels, which accounted for 45%, 60%, and 75% (W1, W2, and W3) of the field water holding capacity. Based on pure nitrogen, four levels of nitrogen application were set: 0.0, 101.6, 203.2, and 304.8 kg·hm−2 (N0, N1, N2, and N3). We measured tree height and diameter at breast height (DBH), and we analyzed the chemical properties of the soil at 0–40 cm depth, from 2007 to 2020. The ranges of DBH, tree height, individual volume, and stand volume were 5.80–25.25 cm, 6.10–16.47 m, 0.01–0.37 m3, and 11.76–481.47 m3·hm−2, respectively. The contents of organic matter, total nitrogen, available phosphorus, and available potassium in the soil ranged from 8.60 g·kg−1 to 18.72 g·kg−1, from 0.21 g·kg−1 to 0.79 g·kg−1, from 8.09 mg·kg−1 to 47.05 mg·kg−1, and from 90 mg·kg−1 to 322 mg·kg−1, respectively. Soil pH value decreased rapidly at a rate of 0.31 units per year for the first five years. Irrigation and nitrogen application, and their interaction, had significant (p < 0.01) effects on soil total nitrogen, available phosphorus, available potassium, and nitrate-nitrogen. We suggest maintaining the field water holding capacity above 60%, with a nitrogen application rate of 203.2 kg·hm−2, to save water, maintain soil fertility, and optimize soil nitrogen supply. Our study aimed to achieve scientific and accurate fertilization of Populus tomentosa stands over different periods, to alleviate the decline of soil fertility, and to improve the utilization rate of water and fertilizer through long-term nutrient monitoring.

“…Irrigation not only provides water for the plant but also can influence soil properties. Adequate irrigation management can increase the moisture content of the soil, enhance biological activities as well as the accumulation of organic matter (OM) and increase the efficiency of organic and mineral fertilisers (Nikolskii et al 2019). Under laboratory conditions, S mineralisation was positively correlated with soil moisture content.…”

Recently, plant-available sulphur (S) in the soil is decreasing due to the limited use of S containing fertilisers and the reduction of atmospheric S deposition. The aim of this work was to evaluate the S status in a long-term fertilisation experiment on a Chernozem in Hungary, with control and 2 NPK rate treatments, considering that after 27 years of superphosphate (SP) use, SP was replaced by monoammonium phosphate in 2010. Plant and soil sampling were performed in 2017 at three different development stages of winter wheat. To assess the S status, the S balance was estimated (for 34 years), KCl soluble soil sulphate, S as well as nitrogen (N) concentration and some amino acids in wheat grain were measured. N/S ratios, S and N uptake of wheat were calculated. The residual effect of SP could be measured only in terms of KCl soluble SO<sub>4</sub><sup>2–</sup>-S in soil. According to the wheat grain S concentration (0.08–0.10%) and N/S ratio (14.9–22.0), wheat was S deficient, despite the positive S balance in the fertilised plots. In this experiment, where S fertiliser was applied with 84 kg S/ha dose in 1983–2010, followed by a 7-year period without S fertilisation, S supply is necessary for achieving adequate wheat quality.
