This study investigates the role of leaf litter and its nutrient input on soil fertility levels in coffee plantations of different ages in Ibadan, Nigeria. Four coffee plantations of 11, 19, 24 and 51 years were selected for the study. Each plantation was divided into four blocks where leaf litter, soil and plant samples were collected and analyzed for nutrient .Results indicated that mean total leaf  litter input in these plantations ranged from 2.50 - 3.5 tha-1yr-1  with a minimum in the 11 year old plantation and maximum in the 51 year plantation. Nitrogen input from leaf litter across the coffee plantations ranged from 27.60 – 60.07 kgNha-1year-1, which was insufficient to meet the nitrogen need of coffee trees. This was reflected by the low nitrogen content of soils of the coffee plantation (0.2 g/kg - 0.8 g/kg) which was below the soil critical nitrogen level of 0.9 g/kg recommended for coffee production. Phosphorus input from the leaf litter in the different plantations was also low 0.38 - 1.73 kgPha-1 as evident from the low phosphorus content of the soil 4.49 - 5.94 mg/kg. This was also reflected in the low leaf phosphorus content of 0.14 - 0.23 g/kg. The potassium content of the leaf litter was also insufficient 17- 55.8 kg Kha-1. Calcium, magnesium, iron, and zinc were sufficient. Coffee leaf litter contributes considerable amount of nutrient to natural soil fertility management of coffee plantations but this is inadequate to meet the nutrient requirement of coffee. There is therefore need for application of fertilizer to supply limiting nutrients.

Leaf Litterfall

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.

Leaf Litter Production

The objective of this study was to determine the effect of Agroforestry systems (AFS) and non-AFS of Theobroma cacao L. on soil and leaf litter quality, during rainy (RS) and dry (DS) seasons in a tropical zone. The treatments were T. cacao crop (CC), Yopo forestry (Anadenanthera peregrina L.) Speg. (YF), Acacia forestry (Acacia mangium Willd.) (AF), Agroforestry system of T. cacao + Yopo forestry (CYF), Agroforestry system of T. cacao + Acacia forestry (CAF), arranged in random design in the field. Leaf litter production was highest in CC (0.79 and 0.73 ton.ha-1) during RS and DS, respectively. CC and AFS improved soil fertility, less Mg in CC; AFS leaf litter quality, CAF in DS and CYF in both seasons, less B and S in DS. AFS can be a solution in tropical zones to solve the problems of low soil fertility.

Total litter fall in mature Eucalyptus obliqua forest is typical for warm temperate forest, in the range 3.6-5.5 t ha-1 yr-1. Fifty per cent of the litter fall occurs in the summer months, and the seasonal rate of litter fall is dependent primarily on temperature. The concentration of nutrients in litter fall varies significantly throughout the year. Prior to litter fall, about 70% of the phosphorus is withdrawn from that portion of the biomass which is to fall as litter and the amount of phosphorus cycled in the litter is therefore very small. At the other extreme, calcium is immobilized in large quantities immediately prior to litter fall. The internal, or 'biochemical', cycling of phosphorus is probably of major significance in the functioning of eucalypt forests on Australian soils characterized by a low phosphorus content.

Leaf Litter Production

<p>La tala indiscriminada de los bosques se asocia con procesos erosivos de los suelos debido, entre otros factores, a la interrupción del proceso de ciclaje de nutrientes. Por este mecanismo, las especies vegetales individualmente o en comunidad pueden contribuir con el retorno de nutrientes a los agroecosistemas. El objetivo del presente trabajo fue evaluar el comportamiento de la producción y descomposición de la hojarasca, y determinar los factores involucrados en estos procesos. Se determinó la producción, descomposición de hojarasca, identificación y cuantificación de organismos del suelo. La relación entre factores ambientales y caída de hojarasca se analizó mediante el coeficiente de correlación de Pearson; para la descomposición foliar se realizaron análisis de regresión. La producción estimada de hojarasca fue de 16,7 y 13,2 t/ha/año en el relicto de bosque seco y sistema basado en <em>Leucaena </em>sp., respectivamente. En el bosque no fue significativa la correlación entre los factores temperatura, humedad relativa y precipitación con la producción de hojarasca; sí se presentó correlación significativa con el factor viento. El mayor componente de necromasa estuvo representado por las hojas, con valores de 62,2% en el bosque nativo y 73,5% en el sistema basado en <em>Leucaena </em>sp<em>. </em>En el bosque nativo se encontró la mayor densidad de organismos; ésta aumentó en la época de lluvias en ambos sistemas y disminuyó a mayor profundidad del suelo. Se registraron altas tasas de descomposición en los sistemas evaluados y las curvas de descomposición presentaron un modelo de tipo exponencial; la tasa más alta se registró en el sistema basado en <em>Leucaena </em>sp<em>. </em>(7,8 x 10-5 t/ha/año).  </p><p> </p><p><strong>Leaf litter production and decomposition of native forest and <em>Leucaena </em>sp<em>. </em>systems in Codazzi, Cesar </strong></p><p>Indiscriminate forest logging is associated with soil erosion processes, due, among other factors, to the interruption of the recycling process. By this mechanism, plant species, individually or in community, can contribute with the nutrient return to agroecosystems. The purpose of this research was to evaluate the leaf liter production and decomposition and to determine the factors involved. Leaf litter production and decomposition, identification and quantification of soil organisms were done. The relationship between environmental factors and leaf fall was analyzed by the Pearson correlation coefficient. For leaf decomposition, regression analysis was performed. Estimated leaf litter production was 16.7 and 13.2 t/ha/yr in a tropical dry secondary and a <em>Leucaena </em>sp. system, respectively. At the forest system no significant correlation was found for temperature, humidity and precipitation with leaf liter, but a significant correlation was found for wind. The greater component of the necromass was due to leaf, corresponding to 62.2% and 73.5% in the forest and the <em>Leucaena </em>sp. system respectively. The highest density of organism was found at the dry forest, increased during the wet season in both systems and decreased with soil depth. High decomposition rates were registered in both systems and followed an exponential model. The highest rate was recorded at the <em>Leucaena </em>sp. system with 7.8 x 10–5 t/ha/yr. </p>
