“…Location 2 had a higher FFB yield mean value compared with the mean FFB yield at location 1. This result is similar to the FFB yield levels reported in OPPs of the Para state and the Amazon region of Brazil [52,53]. The above-mentioned variations in the FFB yield of OPPs is primarily attributed to differences in soil types and soil nutrient status as influenced by nutrient management practices [35,54,55].…”

Oil palm (Elaeis guineensis Jacq.), an industrial oilseed crop, is the most prominent oil-producing crop in the world and one of the highest dry matter producers among C3 plants. It removes large amounts of soil nutrients to support its substantial biomass and oil production. Thus, maintaining adequate levels of limiting nutrients at favorable ratios in the soil is crucial to sustain the required palm nutritional status and oil production over extended periods. We evaluated the levels and ratios of the available soil and leaf nutrients in high-yielding (HYOPP) and low-yielding (LYOPP) oil palm plantations from two locations in southern India and assessed their relations to develop effective nutrient management for sustaining fresh fruit bunch (FFB) production. The FFB yield varied from 2.00 to 31.0 t ha−1 (location 1) and 6.84 to 30.9 t ha−1 (location 2), and the FFB yields of the high- and low-yield population at each location differed significantly. Wide ranges of soil properties, available nutrients, and leaf nutrients concentrations were observed at 0–20- and 20–40-cm soil depths at both locations. The soil nutrient ratios at both sampling depths of the HYOPP were significantly different than the LYOPP at location 1. The mean leaf N (2.09%) and K (0.68%) concentrations at location 2 were significantly higher than those in location 1 (1.85% and 0.54, respectively). The mean leaf concentrations at both locations followed the order N (1.85%, 2.09%) > Ca (1.65%, 1.36%) > K (0.54%, 0.68%) > Mg (0.49%, 0.47%) > S (0.16%, 0.18) > P (0.11%, 0.12%) > B (35.8 mg kg−1, 27.5 mg kg−1). We observed positive and significant correlations between the available N and P at 0–20 cm and between the available N and K as well as Ca and S at both soil depths for HYOPPs. In LYOPPs, the available N was significantly correlated with the available P, K, Ca, and Mg at both soil depths and with the available S at 0–20 cm. The FFB yield of LYOPPs was positively and significantly correlated with the available P and S at the 0–20-cm soil depth and with the available N and P at the 20–40-cm soil depth. Except for a negative correlation (p < 0.05) with exchangeable Ca at the 20–40-cm soil depth, the FFB yield in HYOPPs had no significant correlation with the available soil nutrients at both depths. The FFB yield of LYOPPs had a positive significant (p < 0.01) correlation with the leaf P and K concentrations, while the yield of HYOPPs had a negative correlation (p < 0.01) with the leaf P. Fertilizer accounts for a large part of the on-farm cost in oil palm plantations, and an evidenced approach for fertilizer management based on nutrient contents and ratios in the soil and in the plant is useful for sustainable and profitable production of palm oil.

“…Esta evidência de compactação do solo demonstra a necessidade de que cuidados devem ser tomados para não haver uma maior degradação da qualidade física desse solo, sobretudo na área onde ocorre o tráfego de maquinários. De fato, Sato et al (2017) identificou, na zona de tráfego de área cultivada com palma e óleo, uma degradação da qualidade física do solo, avaliada pelo intervalo hídrico ótimo. Uma redução significativa na biomassa da planta, devido à compactação do solo, foi relatada por Zuraidah et al (2017) em área de cultivo de palma de óleo na Malásia.…”

“…Embora a palma de óleo seja cultivada em diferentes tipos de solos, variações nas propriedades físicas e químicas podem causar diferenças significativas na produção (Woittiez et al, 2017). Avaliando a qualidade física do solo na mesma área estudada, Sato et al (2017) destacou que o estresse hídrico nas profundidades de 20 a 60 cm forneceu evidências de que a variação temporal do conteúdo de água influencia na produtividade da palma de óleo.…”

“…Na América do Sul, o Brasil é um importante fornecedor de óleo de palma, e tem o estado do Pará como maior produtor, onde se concentram mais de 80% da área plantada e com potencial de crescimento (Sato et al, 2017). No polo de produção, que abrange a região nordeste do estado, o cultivo ocupa extensas áreas e a alta produtividade torna o sistema de produção mais dependente do uso de máquinas agrícolas para otimizar as operações de preparo da área, tratos culturais e colheita.…”

RESUMO: Embora a palma de óleo seja cultivada em grande escala e em diferentes tipos de solos no estado do Pará, mudanças nas propriedades físicas do solo nestas áreas não vêm sendo monitoradas. Assim, o objetivo do trabalho foi avaliar a qualidade física de um Latossolo Amarelo cultivado com palma de óleo após 30 anos de implantação. Amostras de solo com estrutura deformada e indeformada foram coletadas nas profundidades de 0-20 e 20-40 cm, na zona de tráfego. O grau de compactação (GC) foi calculado a partir da densidade máxima do solo obtida pelo teste de Proctor e sua resistência à penetração (RP) determinada em amostras equilibradas em dez potenciais matriciais. Influência das mudanças temporais da umidade do solo na RP também foram avaliadas. Os parâmetros GC e RP demonstraram que a área avaliada apresenta compactação. O GC nas duas profundidades ficou acima de 90% sendo mais intenso na camada de 0-20 cm. Porém, quando avaliado pela RP, o estado de compactação foi mais evidente na camada de 20-40 cm e, as variações na umidade do solo ao longo de um ano mostraram que nos meses mais secos o solo apresenta valores limitantes de RP nesta camada. Desta forma, este estudo indica que o crescimento e desenvolvimento da palma de óleo pode estar sendo restringido pela compactação e sobretudo pela elevada resistência à penetração nos meses de menor disponibilidade de água. ABSTRACT:Although oil palm is cultivated on a large scale and in different soil types in the state of Pará, changes in the soil's physical properties in these areas have not been evaluated. Thus, the objective of this study was to evaluate the physical quality of a Yellow Latosol cultivated with oil palm, 30 years after implantation. Soil samples with disturbed and undisturbed structure were collected at 0-20 and 20-40 cm depths, in the machinery traffic zone. The degree of compaction (DC) was calculated from the maximum soil bulk density obtained by the Proctor test, and soil penetration resistance (PR) was determined in soil samples equilibrated in ten matric potentials. Temporal changes in soil moisture in PR were also evaluated. Both parameters showed that the evaluated area has an indication of compaction. The DC in both depths was above 90% and was more severe in the 0-20 cm layer. However, when evaluated by PR, the compaction was more evident in the 20-40 cm layer, and variations in soil moisture over a year showed that in the drier months, the soil showed high values of PR in this layer. Thus, this study indicates that the growth and development of oil palm may be restricted by the soil's compaction and mainly by the high penetration resistance in the months of reduced water availability.

“…The LLWR has been used for identifying the limiting factors for plant growth under different tillage systems (Betz, Allmaras, Copeland, & Randall, 1998;Kahlon & Chawla, 2017;Tormena, da Silva, & Libardi, 1999) and soil management and land use (Calonego & Rosolem, 2011;Fidalski, Tormena, & Silva, 2010;Gonçalves et al, 2014;Reichert, da Silva, & Reinert, 2004), including forest soils (Sato, Lima, Ferreira, Rodrigues, & Silva, 2017;Zou, Sands, Buchan, & Hudson, 2000). The estimated da Silva et al (1994) LLWR values for topsoil conditions have been found to be related to crop yield (Beutler et al, 2008;Beutler, Centurion, & Silva, 2005;Lapen, Topp, Gregorich, & Curnoe, 2004).…”

The least limiting water range (LLWR) has been used as a soil structural quality indicator for identifying in‐season water dynamics, yet studies focusing on its use for detecting in‐season water stresses and their effect on crop response on severely compacted subsoils are scarce. The objectives of this study were, therefore, to examine the in‐season water dynamics on a tile‐drained soil with compacted subsoil in the light of two different approaches for calculating LLWR (standard LLWR by da Silva et al. [1994] and refined LLWR by Pulido‐Moncada & Munkholm [2019]) and to evaluate the crop response to aboveground and belowground conditions. Information on LLWRs was obtained from soil sampling in the most contrasting treatments of a compaction experiment: with and without compaction. In‐season water dynamics were measured from 2017 to 2019. The refined LLWR approach defined a wider range of water content nonlimiting for plant growth compared with the da Silva et al. approach. Compaction affected the LLWRs (p < .05), yet no significant effect of subsoil compaction on crop yield was found. Cumulative aeration and water stress day indicators identified from the refined LLWR were significantly related to grain yield (p < .05). The lower winter wheat yield in 2018 compared with 2019 seemed to be related to the direct impact of weather factors on aboveground growth and to aeration and water stresses. The apparent lack of compaction effect suggests further studies are needed to determine if in‐season stresses derived from the LLWRs can be related to crop development and yield under different soil and weather conditions.
