“…These results are relevant and of great importance to oil palm producers, since it is recommended, as a way to properly manage the crop, the practice of pruning, which is characterized by the removal of the leaves of the oil palm, consisting of leaflets, rachis and petioles, which produced 50.45, 70.66 and 41.48 kg plant-1 of dry matter, respectively (VIÉGAS et al, 2001), being this amount 162.59 kg plant-1 of dry matter of the leaf, deposited in the between rows which will allow the recycling of Cl and other nutrients in the soil. KEE & CHEW (1997) reported that the decomposition and distribution of nutrients in the pruned branches of oil palm trees are relatively fast, with 43% N, 63% P, 76% K and 60% Mg in a 24-month period.…”

In Brazil, the status of chlorine (Cl) nutrition in plants is still poorly studied. The micronutrient Cl plays an important role in cultures such as coconut and oil palm trees. This study aimed to evaluate the status of chlorine nutrition in oil palm trees as a function of planting age, which ranged from two to eight years of cultivation. The experiment was conducted in Tailândia, state of Pará, Brazil. The soil of the area is characterized as Yellow Latosol of medium texture. A total of four oil palm trees were sampled for each age and the following variables were analyzed: leaf, petioles, rachis, palm heart, arrows, stipe, male inflorescences, peduncles, spikelets and fruits, as well as the accumulated, recycled and immobilized levels of Cl. Oil palm trees proved to be demanding in Cl and the accumulation in the different vegetative organs increased with the development of the plant. The stipe was the main storing vegetative organ of this micronutrient. The highest demand of Cl (16.9-26.0 g/kg) occurred in the palm heart, while for male inflorescence, the values ranged from 3.3-4.1 g/kg of Cl. The levels of Cl recycled by the plant were higher than the immobilized and exported levels considering the development up to 4 years of age. After this age, the levels of recycled Cl are lower than those immobilized. As for the amount of Cl exported by clusters in 8-year-old plants, the values were 3.2 and 1.3 times lower than the recycled and immobilized levels, respectively.

“…The crown, the second largest component in P accumulation (Figure 3), influences nutrient cycling, as deposition of its organs on the soil between crop rows provides a nutrient return (VIEGAS et al, 2001). The decomposition of oil palm leaves allows distribution of P (63%), N (43%), K (76%), and Mg (60%) during 24 months of planting (KEE and CHEW, 1997).…”

Amazon soils have a low phosphorus (P) availability and few studies have investigated nutrition of palm oil plantations. This study assessed the effects of P nutrition on oil palm organs according to plant age. The experiment was carried out under field conditions, at the enterprise Agropalma S/A, in the municipality of Tailândia, Pará State, Brazil. The experimental design used was completely randomized with four replications and comprised seven treatments: plants age (2, 3, 4, 5, 6, 7, and 8 years of planting). We evaluated P concentration, accumulation, and exportation in plant components (leaflets, petioles, stipe, rachis, palm heart, arrows, male inflorescences, peduncles, spikelets, and fruits). Palm heart (10.9 g kg-1) and male inflorescence (3.8 g kg-1) showed the highest P concentrations in the vegetative and reproductive organs, respectively. On the other hand, the largest P accumulations were observed in the stipe (159 g plant-1) and fruits (59 g plant-1), increasing from the 3rd year of age of the plants. Bunches exported the largest P amounts (81 g plant-1), especially in older plants. The oil palm immobilizes (24 kg ha-1) and recycles (23 kg ha-1) a large amount of P, more than it exports (12 kg ha-1) P.

“…In the frond-stacked area, decomposition of fronds can replenish substantial quantities of nutrients back into the soil via mineralization processes since fronds contain considerable amount of nutrients (e.g. 10 ton of frond dry matter contained 82 kg N, 7 kg P and 102 kg K; Kee and Chew, 1997). The temporal release of nutrients (i.e.…”
