“…Soil application of N was reported to effectively increase YANs in grapevine berries [10,11], but this strategy can be expensive with serious economic and environmentally negative consequences [12]. Since the pollution related to N fertilization represents a main environmental concern in many cropping systems around the world [13], research into efficient and environmentally friendly fertilization strategies represents the main goal of many growers, extension specialists, scientists as well as in agricultural governmental policies [14][15][16]. Foliar application of N is generally considered more environmentally friendly compared to soil application because it directly targets the plant [17][18][19] reducing the risk of nitrate leaching [20].…”

Reaching a sufficient yeast assimilable nitrogen (YAN) content in berries at harvest is considered a main viticultural goal for wine-making, because low YANs can slow down must fermentation and have negative effects on wine sensory attributes. For this reason, many attempts have been made to define correct fertilization strategies to stimulate YAN accumulation in the berries. Foliar application of amino acid-enriched urea fertilizer is considered a promising environmentally friendly strategy for improving the yield and nutrient efficiency of plants. The aim of this two-year research was to study the effects of two fertilizers based on urea enriched with amino acids applied at low doses in diverse phenological stages on berry YAN concentration in ‘Greco’ grapevines. The results of this study indicate that amino acid-enriched urea fertilizers induced an increase in YANs in the ‘Greco’ berries at harvest, but only when the application was undertaken at full veraison. Foliar applications applied at veraison onset or post-veraison appeared to be ineffective. In addition, the fertilizers enhanced YAN accumulation in the berry without modifying the other composition parameters measured in this study (total soluble solids, titratable acidity, pH and malic acid). Therefore, the results of our study suggest that foliar application of urea fertilizers enriched with amino acids is an effective strategy to increase yeast-assimilable nitrogen concentration in grapevine berries at harvest.

“…Participants believed there are societal shifts in expectations for the pastoral farming sector generally. These include the adoption of sustainability and animal welfare measures which can be market driven (Lyons & Lawrence, 2017), or come from government agencies through regulation and policy (Kaye-Blake et al, 2019), subsidies (Gołębiewska & Pajewski, 2018Pajewski et al, 2020) and taxation shifts (Barrett & Makale, 2019). A mix of intrinsic and extrinsic motivations like these are expected to drive farmer efforts to reduce their environmental footprint.…”

There have been horizon scans (strategic science reviews) recently for weed biology, but none that focus on weeds of pastures. Here we report on our process for writing the Pastoral Sector Weeds Research Strategy (2018)(2019)(2020)(2021)(2022)(2023)(2024)(2025)(2026)(2027)(2028) for New Zealand and then follow-up with the focus of the current article, a horizon scan for pastoral weed science. Scientists and stakeholders involved in weeds and pasture systems participated in two workshops to determine which issues and opportunities are emerging as drivers of innovation for weed science and weed management. We identified 11 major issues and 46 subordinate ones, but the three most highly ranked major issues were: 1) anticipated reductions in our access to herbicides; 2) rethinking weed management under an ecosystem services paradigm; 3) responding to a regulatory push for farm system planning designed to address biosecurity risk, biodiversity, carbon budgets, contaminants, and nutrient run-off in addition to production value. The workshop participants were asked to rank the 3 major issues (and some subordinate ones) using the criteria: 1) is this a horizon (is the issue or question likely to become more important in 10-20 years?); 2) will it require stretchy science (is the question or issue currently not well addressed by the science community?); 3) is it transformative (will successful scientific research in this area lead to significant changes to weed management in pastures?). Most of the issues identified are shared in pastoral systems worldwide and involve reducing environmental footprint of farming while maintaining productivity.

“…Increased nitrogen concentrations and loads in Southland rivers have been linked to declining water quality (Hamill and McBride 2003 ; Monaghan et al 2007 ), and consequent eutrophication of rivers and estuaries (Stevens et al 2022 ). There remains significant potential for agricultural intensification (Kaye-Blake et al 2019 ), which would almost certainly be associated with increased nitrogen loss (Vogeler et al 2014 ; Vibart et al 2015 ).…”

Land-use Suitability is Not an Intrinsic Property of a Land Parcel

Agricultural production has economic, environmental, social and cultural consequences beyond farm boundaries, but information about these impacts is not readily available to decision makers. This study applied the land use suitability concept by carrying out an assessment of a region that has the potential for intensification of agricultural production, but where eutrophication of river and estuary receiving environments due to nitrogen enrichment is a significant issue. The assessment evaluated three indicators for each farmable land parcel in the region: productive potential (the inherent productive and economic potential of the parcel), relative contribution (the potential for the parcel to contribute nitrogen to receiving environments compared to other land parcels), and pressure (the load of nitrogen delivered to receiving environments compared to the loads that ensure environmental objectives are achieved). The assessment indicated that land with high suitability for land-use intensification in Southland is limited because areas with high productive potential and low relative contribution rarely coincide with receiving environments with low pressure. Existing data, methods and models can be used to calculate the indicators under different choices for regional land-use intensity and receiving environment objectives. However, the spatial resolution and accuracy that is achievable may preclude using assessment outputs to make land use decisions at small spatial scales such as individual farms. The study highlighted that land use suitability is not an intrinsic property of a land parcel because it is dependent on choices about land use elsewhere in the landscape and the environmental objectives, and that land use suitability is inherently subjective because of decisions that concern how indicators are combined and weighted.
