Summary: Optimizing the productivity of loblolly pine involves considering both abiotic and biological factors, with a focus on the diverse ectomycorrhizal fungal communities that colonize the roots of these trees. This review explores the effects of commonly applied macronutrients (N, P, and K) on the relationship between loblolly pine and ectomycorrhizal fungi, and proposes future directions for research to optimize productivity in pine plantations.

Summary: Microbial communities play a crucial role in nutrient uptake and stress tolerance for plants. Variability in root traits and soil microbiomes among switchgrass cultivars contribute to differences in yield and environmental responses. Soil properties strongly influence the structure of soil bacterial and fungal communities in plant ecosystems.

Summary: Intercropping significantly increased grain yield and plant P-use efficiency compared to monocropping, with sufficient P supply and increased light interception delaying leaf senescence and improving overall plant performance. The interaction between shoot and root plays a key role in regulating resource-use efficiency in intercropping systems.

Summary: Forest production heavily relies on nutrient uptake, and understanding the relationship between nutrient availability and silvicultural practices is crucial for sustainable management of intensively managed plantations. The study on early loblolly pine stand development showed that management practices such as controlling competing vegetation and early fertilization can significantly increase nitrogen content, but long-term nitrogen dynamics and growth are dependent on early fertilization.

Summary: The study compared selectively bred switchgrass cultivars with undomesticated strains in a three-year field experiment. While cultivars had slightly higher biomass and plant density in the third year, they also showed lower survival and persistence compared to commercial ecotypes, resulting in no significant difference in plant densities. The breeding of current switchgrass cultivars did not enhance traits associated with invasiveness, suggesting that the use of commercial ecotypes in biomass grasslands could provide functional benefits without large losses in biomass production.

Summary: This study investigates the prevalence and epidemiology of a little-studied North American virus, SwMV, in switchgrass and other grasses in the US Midwest. The results show that this apparently wild virus is well-established and widespread, with infection present at nearly all sites and a prevalence ranging as high as 33%-60%. Although wild viruses are believed to have benign relationships with their natural hosts, SwMV has the potential to impact yield components.

Summary: By analyzing the tissue-specific transcriptome and metabolites of different drought-tolerant genotypes of switchgrass, this study reveals the association between drought tolerance and specialized metabolic pathways. Specific diterpenoids in switchgrass roots accumulate under drought conditions, while triterpenoid abundance remains unchanged.

Summary: The study found that different row configurations have a significant impact on light interception and light use efficiency of maize and peanut in intercropping systems. In dry years, the light use efficiency of intercropped maize was lower than monoculture, while that of intercropped peanut, especially in certain configurations, was higher. Light interception and use efficiency varied with changes in border-row proportion.

Summary: Forage maize and sorghum can improve their quality by intercropping with annual legumes, leading to greater dry matter and light interception. The land equivalent ratio was higher in intercropping systems compared to sole crops. Maize produced more dry matter than brown midrib and brachytic dwarf sorghums, and both LAI and LI increased rapidly before stabilizing. Intercropping systems reached greater LAI and intercepted more light earlier than sole crops. RUE varied with season, crop, and year. Lablab was found to be superior to lima bean for intercropping with maize or sorghum for forage production.

Summary: Managed loblolly pine forests in the southeastern US have the potential to increase carbon storage and soil health through vegetation growth and intensive management practices. Intercropping loblolly pine with switchgrass can lead to higher concentrations of soil organic carbon and nitrogen, particularly in deeper soil horizons. The input of new plant-derived organic matter and increased microbial activity contribute to the buildup of stable organic matter pools in the soil.

Summary: Fine roots are dynamic in responding to environmental conditions and serve as the primary interface between trees and the soil. This study evaluated the effect of genotype and site on the fine root dynamics of loblolly pine. The results showed that environmental conditions were related to standing fine root biomass and intensive silvicultural practices supported aboveground growth.

Summary: Compared to other STEM programs, students of color show less interest and involvement in forestry. This study aims to understand the reasons why graduate students of color choose to pursue a career in forestry. Initial results indicate that these students are motivated by specific forestry topics, but have different expectations in terms of career and financial opportunities. The findings of this study could provide ideas for promoting diversity in the field of forestry, but further research is needed.
