The present investigation was attempted to assess the leaf litter production, decomposition rate and amount of major nutrient return in Populus deltoides, Eucalyptus tereticornis, Tectona grandis and Pyrus pyrifolia based agroforestry land use systems in Taran Taran district which falls in the north western agro-climatic zone of thePunjab state, India. The litter production in selected tree species was quantified using litter traps and decomposition pattern of leaf litter was investigated by litter bag technique. Litterfall in the selected tree species varied significantly (5 % level of significance) during different months of the study period. Among the four species, P. deltoides exhibited highest leaf litter production (7.8 tons/ha) followed by T. grandis (1.83 tons/ha) and E. tereticornis (1.77 tons/ha) whereas, lowest leaf litter production was observed in P. pyrifolia (0.34 tons/ha). The present study also showed that temperature as compared to rainfall play a significant (5 % level of significance) role in litter decomposition. In case of P. pyrifolia, P. deltoides and T. grandis decomposition take place 100 per cent, 98 per cent and 99 per cent respectively after 10 months whereas in E. tereticornis 87.7 per cent leaf decomposed after 10 months. The nutrients percentage through litter fall was maximum of nitrogen (2.27 %) followed by potassium (1.90 %) and phosphorous (0.32 %). Maximum and minimum N input through leaf litter was in P. deltoides (2.27 %) and P. pyrifolia (1.15 %). The K input (%) was maximum in leaves of T. grandis (0.32) and minimum in E. tereticornis (0.21). The maximum input of P (%) through leaf litter was in P. deltoides (1.90) whereas, minimum value was observed in E. tereticornis (1.27). Tree based agroforestry land use systems improve soil nutrient status as compared to traditional wheat and paddy based land use systems under this region of Punjab. Therefore tree based land use systems need to be promoted over the traditional field crops for realizing better environmental benefits in this region.

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.

Mangrove litter production is important in the displacement of organic matter from mangrove vegetation to water such as in the coast of West Muna Regency. However, one factor influencing it is the frequency of rainfall. This research, therefore, aims to determine the influence of the frequency of rainfall in mangrove ecosystem by obtaining data through the fractional wet weight. The results showed that the biomass fraction with the largest amount were Rhizophora mucronata, Rhizophora apiculata, and Sonneratia alba with of 31.59; 31.07; and 30.96%, respectively, while the lowest was Rhizophora stylosa, Bruguiera cylindrica, and Bruguiera gymnorrhiza with of 30.07; 30.10; and 31.95%, respectively. The species with the largest leaf litter production was Bruguiera cylindrica, with of 1.72 g.m-2.day-1 which occurred in April and the lowest was Rhizophora apiculata, 0.24 g.m-2.day-1 in August. The species with the largest leaf litter production was Bruguiera cylindrica, 1.96 g.m-2.day-1 which occurred in May and the lowest was Sonneratia alba, 0.29 g.m-2.day-1 in August. In addition, the species with the largest fruit litter production was Rhizophora apiculata, 1.76 g.m-2.day-1 in April and the lowest was Sonneratia alba, 0.32 g.m-2.day-1 in September. The total litter production was 18,75 g.m-2.day-1 consisted of 6,69 g.m2.day-1 leaf litter, 6,54 g.m-2.day-1 branch litter, and 5,52 g.m-2.day-1 fruit litter. The higher the frequency of the rain, the greater the litter production.   Keywords: biomass fraction, seasonal litter production, West Muna Regency

Litterfall and its nutrient return in five oak species were studied in the mixed Oak forest in Senapati District, Manipur .Litter production was measured by litter trap method. The total annual litterfall was 958.9 g m-2yr-1.Leaf and non leaf litterfall comprises 76.7 % and 23.3 % of the total litterfall. Maximum litterfall was found in the month of April (193.5 g m-2) and minimum in the month of July (23.7 g m-2).About 70% of the forest floor was replaced each year with turnover time of 1.42 yr.The amount of nutrient return through leaf litter was found to be maximum in Q.polystachya and minimum in C.indica. Nutrients (NPK) concentration of leaf litter of five different tree species was varied among different tree species.

Climate is an important driver of litterfall along different ecosystems. However, little is known about how climate affects litter production in plant communities of Restinga. The aim of this study is to characterize the temporal variation in leaf litter production in an Open Clusia Formation in Restinga de Jurubatiba National Park, from 2001 to 2018, and assess how local variability in litter production reflects the local climatic conditions and its variability. We tested the hypothesis that monthly leaf litterfall increases in dry months and in drier and warmer than average months; we also evaluated if annual leaf litterfall increases in wetter and warmer years following leaf production patterns, that increases in these conditions. We found that litterfall peaks in the drier months. This pattern is consistent for many tropical ecosystems, even evergreen ecosystems, and may have evolved as a strategy that result in reduced water stress by plants, during drier and warmer periods, or may simply be a stress symptom. However, we also found that decreases in monthly rainfall and increases in monthly ∆Temperature (temperature observed minus estimated based on 1970-2000 interval) stimulate leaf litter production. Hot and warmer than average years also seem to stimulate leaf litterfall. It suggests that annual leaf litterfall and leaf production are less affected by precipitation regimes than variations in temperature (or radiation, which is directly related to temperature). It may result from the fact that Clusia hilariana, the dominant species in this ecosystem which accounts to 80 % of leaf litterfall, is a CAM photosynthesis species, a characteristic commonly associated with avoidance of water stress by plants. Although leaf litterfall seems to be predominantly driven by climate at annual scale, only 15 % of its variation was associated to climate at seasonal scale, suggesting that local factors control litterfall at lower temporal scales in Open Clusia Formation.
