Summary: The intensification of the US dairy industry has led to increased reliance on maize silage as a primary forage source, resulting in higher carbon losses compared to perennial forages like alfalfa. Including alfalfa in crop rotation can reduce carbon losses, but net losses are still observed. Winter rye cover crops and applications of liquid dairy manure marginally improved carbon balances but were insufficient to offset losses in respiration and crop harvest.

Summary: The flowering of perennial ryegrass is crucial for both farmers and seed producers, as it affects metabolizable energy content and seed yield. Gene studies on flowering time regulation can provide insights into the growth and flowering processes of ryegrass.

Summary: This study aimed to investigate the effects of using pulp silage of grass fractionated once or twice on fiber kinetics, protein value, and production of CH4 in dairy cows. The results showed that feeding pulp silage of grass fractionated twice resulted in better fiber digestibility and protein value compared to feeding silage of chopped grass. Further research on the effects of physical processing of forage on fiber kinetics is needed.

Summary: An experiment was conducted to compare the rumen fermentation and degradability of three forage treatments. The results showed that multispecies forage had a positive impact on rumen pH and dry matter degradation, but had no significant effect on dry matter intake and milk yield.

Summary: Synchronizing fertilizer timings with both crop N demand and local weather patterns can significantly enhance nitrogen use efficiency (NUE) in cropping systems. The optimal timing of nitrogen application varies with rainfall patterns, and the mobility of nitrogen in soil also affects plant nitrogen uptake.

Summary: The study found that cropping sequences based on creeping red fescue had the highest economic benefits and crop yields, while continuous canola sequences ranked lower. Sequences based on clover were found to improve the performance of subsequent wheat and canola crops.

Summary: Maize silage is an important component of dairy feed rations, but its nutritive value can be compromised by in-season changes in crop development. In this study, the Agricultural Production Systems Simulator (APSIM) was calibrated to accurately predict changes in crop partitioning and composition, specifically the harvest index (HI) of maize silage. The model showed good simulation performance for crop growth and phenology, and the main drivers of HI variability were found to be genotype and water status. The calibrated APSIM model can be used to improve maize silage nutritive value and assist in genotype selection and harvest timing decision-making.

Summary: The study found significant changes in control of cup plant, maize yield, and nitrogen release after perennial energy crops were converted to arable cropping, indicating that proper crop rotation can help reduce the risk of nitrogen leaching.

Summary: This study found that cows grazing diverse mixtures in a full-grazing dairy system increased their milk yield, but methane emissions also increased. The high feed quality and milk yield from both mixtures resulted in relatively low methane emissions.

Summary: The aim of the experiment was to determine the optimal ratio between maize silage and grass-clover silage in lactating dairy cow diets. The evaluation was based on nutrient digestibility, rumen metabolism, and total carbon footprint. Four diets varying in proportions of grass-clover silage and maize silage were fed to lactating Holstein cows. The results showed that increasing the proportion of maize silage in the feed ration led to an increase in dry matter intake and a decrease in methane emission.

Summary: The study highlights that perennial ryegrass has lower yields and persistence in monoculture compared to other cool-season grasses, but higher nutritive value. Grass-legume mixtures show higher yield stability across locations and production years compared to monocultures. This research emphasizes the ongoing need to improve forage production and persistence of perennial ryegrass in cold environments.

Summary: The study investigated the impact of soil-plant interactions on N2O emissions through a greenhouse experiment, revealing that mixed plant species showed higher nitrogen use efficiency and soil microbial activity. However, young age swards of Plantago lanceolata may not effectively reduce N2O emissions.

Summary: This study investigated the effects of different nitrogen application rates on yield, quality, and nitrogen recovery efficiency of forage maize under different climatic conditions in Finland. The results showed that the different nitrogen application rates did not significantly affect forage quality and nitrogen recovery efficiency. It is recommended to maintain nitrogen application rates at 100-150 N kg/ha in the boreal region.

Summary: This study aimed to investigate how efficiently assimilated carbon (C) is incorporated in plant biomass and its implications for sequestration in intensively managed grassland. The research showed that highly fertilized grasslands can lose their ability for C sequestration due to low belowground carbon allocation, leading to become a net carbon source.

Summary: The study found that legume-based nitrogen sources result in significantly lower emission factors compared to mineral nitrogen based dairy systems. Emissions from grazed pastures were highest within the first 60-75 days, while the emissions from urine and dung patches were relatively smaller.

Summary: In recent years, secondary plant metabolites with antimethanogenic properties have been identified, particularly in tannin-rich forages. However, the variability in results and effects on animal performance and nutrition are highly inconclusive. Understanding the structural characteristics of tannins and optimizing analytical techniques can lead to more comparable and repeatable results in studying their antimethanogenic potential.

Summary: The effects of climate change on agricultural ecosystems, particularly drought, have significant ecological, social, and economic implications. Analysis of long-term climate data reveals that climate changes and variability did not significantly affect forage production, but extreme dry conditions may have a notable impact on yields.

Summary: Converting grassland to arable cropping can lead to decreased soil organic carbon (SOC) stocks, impacting soil and climate protection goals. However, using direct drilling in forage production systems like silage maize can prevent SOC stock degradation without reducing herbage yield. Long-term practices, such as a three-year grass phase followed by three years of silage maize, can help maintain SOC stocks.
