Comparison of Productivity and Quality of Three Perennial Ryegrass Cultivars and Their Mixture in Response to Nitrogen Fertilization and Grass-Legume Mixtures

Plants, Journal Year: 2024, Volume and Issue: 13(22), P. 3130 - 3130

Published: Nov. 7, 2024

We conducted a four-year cutting experiment on herbage yield, with three years focused testing the effect of perennial ryegrass (PR) cultivars 'Elena DS', 'Raminta', and 'Verseka', along cultivar mixture compositions white clover (WC) red (RC) diversity, crude protein (CP), modified acid detergent fibre (MADF), neutral (NDF), water-soluble carbohydrates (WSC), dry matter digestibility (DMD) content. PR mixtures were sown alone (N

Perennial grassland agriculture restores critical ecosystem functions in the U.S. Upper Midwest

Frontiers in Sustainable Food Systems, Journal Year: 2022, Volume and Issue: 6

Published: Dec. 2, 2022

Dominant forms of agricultural production in the U.S. Upper Midwest are undermining human health and well being. Restoring critical ecosystem functions to agriculture is key stabilizing climate, reducing flooding, cleaning water, enhancing biodiversity. We used simulation models compare (food-energy production, nutrient retention, water infiltration) provided by vegetation associated with continuous corn, corn-soybean rotation, perennial grassland producing feed for dairy livestock. Compared most dramatically improved system (nitrate leaching reduced ~90%, phosphorus loss ~88%, drainage increased ~25%, evapotranspiration ~29%), which will translate services. Our results emphasize need incentivize multiple services when managing landscapes.

Opportunities for Adaptation to Climate Change of Extensively Grazed Pastures in the Central Apennines (Italy)

Land, Journal Year: 2023, Volume and Issue: 12(2), P. 351 - 351

Published: Jan. 28, 2023

Future climate change is expected to significantly alter the growth of vegetation in grassland systems, terms length growing season, forage production, and climate-altering gas emissions. The main objective this work was, therefore, simulate future impacts foreseen context two pastoral systems central Italian Apennines test different adaptation strategies cope with these changes. PaSim simulation model used for purpose. After calibration by comparison observed data aboveground biomass (AGB) leaf area index (LAI), simulations were able produce various outputs, such as AGB, greenhouse (GHG) emissions, time windows (i.e., 2011–2040 2041–2070) using 14 global models (GCMs) generation data, according RCP (Representative Concentration Pathways) 4.5 8.5 scenarios under business-as-usual management (BaU). As a result increasing temperatures, fertilizing effect CO2, similar trend water content between present future, showed lengthening season mean increase: +8.5 days RCP4.5 RCP8.5, respectively, period 2011–2040, +19 31.5 rise production peak increase sites BaU: +53.7% 62.75% RCP4.5. period, +115.3% 176.9% RCP8.5 2041–2070, respectively,). Subsequently, three alternative tested: 20% animal stocking rate (+20 GI), 15% grazing (+15 GL), combination factors GI × 15 GL). Simulation results on suggest that favorable conditions could support +20 GI, +15 GL, Under projections, net ecosystem exchange (NEE) nitrogen oxide (N2O) emissions decreased, whereas methane (CH4) rose. simulated GHG changes varied magnitude tested. development assessment extensive pastures Central provide basis appropriate agricultural policy optimal land response ongoing change.

Nutrient availability challenges the sustainability of low-input oil palm farming systems

Farming System, Journal Year: 2023, Volume and Issue: 1(1), P. 100006 - 100006

Published: March 28, 2023

The social and economic benefits for smallholders cultivating oil palms are usually associated with environmental degradation high resource consumption inherent to intensive farming systems.Nonetheless, the extensification of agricultural practices by many due limited access funds, inputs, or knowledge may result in a more environmental-friendly palm production.Here, we assessed trade-offs between production soil two systems established on forested land Ngwei region (Cameroon) comparing no (smallholder system, SH) low (elite EL) inputs (fertilizer, herbicides).Soil characteristics, nutrient deficiencies were determined forty-two plantations different age covering one full plantation cycle.The rates organic carbon (SOC) loss similar both (À0.029AE 0.012 kg C m À2 yr À1 ), but bulk density pH not affected forest conversion.Soil available potassium (K) decreased sharply during first 7.3 AE 0.9 years before stabilizing.Potassium fertilization leaflet K immature phase EL, was sufficient prevent phase, reaching similarly nutrition index as SH (0.68 0.13).Oil growth systems, fresh fruit bunches (FFB) enhanced 38 11% EL.The nitrogen (N) pronounced systems.However, higher biomass export EL induced phosphorus depletion soils reinforced N compared SH.Despite degradation, agroecosystem threatens sustainability these low-input systems.This calls optimization, such targeted intensification system reduced system.
