Leaf Litter Production

The deposition of leaf litter on the forest floor is influenced by biotic and abiotic factors where forest fragments are inserted, which is a major source of nutrients to the soil. The objective of this study was to evaluate the influence of the change in relief conditions (landform) in leaf litter contribution and nutrient content in a Submontane Seasonal Semi-deciduous Forest in Pinheiral (state of Rio de Janeiro, Brazil). It was selected two adjacent landforms with convex and concave relief type and they divided into small sites (SS), obeying the variation of the slope and topographic gradient. Five conic collectors with an area of 0.2834 m² were installed in each SS, totaling 30 collectors. The collections of leaf litter were carried out every 30 days during a year. The material retained in the traps was separated as the fractions; leaves, twigs, reproductive and other material to assess the proportion of each fraction in the leaf litter production and nutrient content of the fraction leaves. The contribution and nutrient content of litter are influenced by the type of landform and seasons of the year. The highest contribution was observed in the dry season, in the lower and middle SS of the landforms, and the highest nutrient levels occurred in the convex landform during the rainy season.

Plant Nutrient Content

Approximately 50 million metric tons of poultry wastes are produced annually in the United States. Production of this byproduct is not without costs. Cost incurred for handling and disposal of broiler litter, for example, has been estimated to be .26c per kg of liveweight salable bird [1].Although costs are associated with this byproduct, it is not a source of revenue for many producers. The traditional use of litter has been as a fertilizer. However, for many poultry producers, land is a limiting factor. In some cases, the value of the plant nutrient content of the wastes does not justify their use instead of commercial fertilizers when handling costs are considered. Thus in many instances these wastes create a pollution problem and may be negatively priced.

Mature Stands

Production of forest litter was examined over 2 years in a chronosequence of stands representing four stages of secondary succession on well-drained uplands of the East Gulf Coastal Plain in Mississippi. Average age for these stands was from 22 to 207 years. Early succession was dominated by dense pine stands, whereas mature forests were about 75% hardwood. Litter mass was greatest early in succession, when productivity was highest, and decreased as stands matured. Foliage was approximately 70% of the litter throughout succession. The remaining 30% was mostly large woody material in young pine stands, but a heavy reproductive component in mature stands. Stands dominated by pines produced litter throughout the year, whereas hardwood stands were more cyclic. In young pine stands, the N and P content of litter was already 80–90% of the maximum value realized later in succession, whereas Ca and Mg accumulated in proportion to hardwood basal area. Nutrient concentrations in litter varied by season, component, and stage of succession. Foliar litter that fell in the spring and summer had higher N and P concentrations than that that fell in the fall. Seasonal patterns of litter production, as well as variations in nutrient concentration, made the monthly variation of nutrients returned to the forest floor less extreme than that of foliar litter fall weights.

Control Factors

Tree and shrub litter production was measured over 2 years in 12 jack pine (Pinusbanksiana Lamb.) and 2 white spruce (Piceaglauca (Moench) Voss) dominated stands located in the Hondo – Slave Lake and Athabasca Oil Sands areas of north central and northeastern Alberta. Annual and daily production rates were calculated for foliage (by species), male cones, and structural material (bark, twigs). Annual litter fall weights were typical of those measured in other boreal regions and were correlated with stand basal area. Seasonal patterns in daily production rates suggested that three classes of control factors were involved in determining litter fall rates within a stand. Random factors, such as weather, and chronic factors, such as insect or disease activity, contolled foliage and structural litter through most of the year. Predictable seasonal factors relating to plant physiological state controlled autumn foliage litter fall in deciduous and most coniferous species and production of male cone litter in early summer.

Land degradation is the result of soil mismanagement that reduces soil productivity and environmental services. An alternative to improve degraded soils through reactivation of biogeochemical nutrient cycles (via litter production and decomposition) is the establishment of active restoration models using new forestry plantations, agroforestry, and silvopastoral systems. On the other hand, passive models of restoration consist of promoting natural successional processes with native plants. The objective in this review is to discuss the role of litter production and decomposition as a key strategy to reactivate biogeochemical nutrient cycles and thus improve soil quality in degraded land of the tropics. For this purpose the results of different projects of land restoration in Colombia are presented based on the dynamics of litter production, nutrient content, and decomposition. The results indicate that in only 6–13 years it is possible to detect soil properties improvements due to litter fall and decomposition. Despite that, low soil nutrient availability, particularly of N and P, seems to be major constraint to reclamation of these fragile ecosystems.

Soybean Yield

Broiler litter (BL) has the potential to be used as an alternative multi-nutrient source for soybean (Glycine max L.) production. While previous research on soybean yield response to BL has reported inconsistent results, the effects of BL application on soybean seed nutrient concentrations are largely unknown or less studied. The objective of this two-year field study was to investigate the effect of BL application on soybean yield and seed nutrient content in three different soil types and production environments. To pursue the objective, a field experiment was established in 2018 in a Compass loamy sand with four BL rates (0, 2.2, 5.6, and 11.2 Mg BL ha−1). In 2019, the study was expanded to include two additional soil types (Decatur silty clay loam and Dothan fine sandy loam) totaling four site years. The experimental design at each site was a randomized complete block with four replications. Application of BL had no impact on soybean yield in the first year, regardless of application rate and soil type. In the second year of BL application, soybean yield was 43% higher overall compared to no BL plots on a Compass loamy sand. However, soybean yield with the application of 5.6 or 11.2 Mg BL ha−1 was not statistically different from that at 2.2 Mg BL ha−1. Soybean seed Ca and B concentrations changed significantly among the treatments; however, the change was not consistent across the sites. Consecutive year application of 11.2 Mg BL ha−1 yr−1 produced the highest seed K and Cu concentrations. The results of this research suggest that repeated BL application can boost soybean yield and potentially enrich seed with selected nutrients.
