“…Their work showed that higher amounts of clay that increased with increased depth indicated higher moisture and nutrient contents. The contents of the major nutrients were low being less than critical levels as reported by Subramaniam et al 19 and Behera et al 20 . Except for available P which was above the critical level as reported by Bai et al 21 .…”

Background and Objective: Potassium is the most utilized element by oil palm for bunch production. It is labile and exists in four major forms that are in equilibrium with one another. It is important to know the form of K that correlates more with the bunch yield of oil palm. The objective of the study was to determine the most dynamic form of K that correlates with bunch yields of oil palm in an Ultisol. Materials and Methods: Potassium forms and dynamics and their relationships with fresh fruit bunch yields were studied in soils sampled from profile pits, accurately labelled, processed and analyzed for physical and chemical properties and forms of potassium using standard laboratory methods. Activities of potassium, calcium and magnesium were determined from their respective activity coefficients which in turn were determined from the extended Debye and Huckel equation. Results: The HNO 3 extractable K was the most dynamic form of K and constituted 31.95% of total K reserves bunch weight was significantly and positively correlated with HNO 3 extractable K (difficultly exchangeable K) with r = 0.943, p<0.01), residual K (r = 0.924, p<0.01); potassium activity coefficient (r = 0.834, p<0.01); calcium activity coefficient (r = 0.827, p<0.05) and calcium activity (r = 0.867, p<0.05). Bunch weight also correlated positively and significantly with the number of harvested bunches with (r = 0.902, p<0.05). Conclusion: It highlighted the need to manage the organic matter, nitrogen, potassium and calcium contents of Ultisols under oil palm by deliberate application of empty fruit bunches (EFB) to increase the total K reserve of the soil.

“…Para Indonesia, a través de un simulador llamado "Agricultural Production Systems sIMulator (APSIM)" estimaron el crecimiento de plantación del cultivo (Akram et al, 2022). Los resultados sugieren que para una plantación de 0 a 8 años, se requieren entre 2500 mm y 3900 mm de riego anual, necesidades de riego que a largo plazo pueden afectar los niveles freáticos de diversas regiones tropicales del mundo, es más, el problema de la falta de riego puede ser mayor, ya que las estimaciones no toman en cuenta las necesidades de riego para la producción de fruta fresca (Akram et al, 2022;Subramaniam et al, 2020).…”

Introducción. La palma de aceite (Elaeis guineensis) es uno de los monocultivos perennes que se ha extendido a casi un poco más de diecinueve millones de hectáreas en el mundo, su expansión ha generado debate social, económico y político en diversos países tropicales. Una de las problemáticas que se ha discutido, es el impacto sobre las propiedades fisicoquímicas, biológicas y ecológicas del suelo. Objetivo. (i) Ofrecer un panorama actual de la expansión del cultivo de palma de aceite para una zona de la región Soconusco, Chiapas, México, (ii) documentar los efectos que provoca la palma de aceite sobre las propiedades fisicoquímicas y biológicas del suelo y (iii) presentar algunas propuestas de prácticas de manejo para incrementar la fertilidad y la abundancia de macroinvertebrados del suelo. Desarrollo. Se realizó la búsqueda de palabras clave en el apartado de “tópicos” dentro de la base de datos “Web of Science” del año 2009 hasta marzo del 2018. Se consultaron investigaciones que relacionan el cultivo de la palma de aceite con los parámetros físicos, químicos y biológicos del suelo. La literatura demuestra los efectos negativos que genera el monocultivo de palma de aceite sobre algunas propiedades fisicoquímicas del suelo y sobre la ecología y biología de la macrofauna edáfica. Conclusión. Se muestra evidencia de que el mal manejo del monocultivo de la palma de aceite tiene implicaciones ambientales. La integración de buenas prácticas de manejo sostenibles, podrían mitigar los daños al suelo.

“…Regarding the first stream, the water footprint theory proposed by professor Hoekstra [5] provided an effective accounting and evaluation tool for the research of water security strategy, which has become one of the hot spots in the field of water resources management. Based on this theory, water was regarded as one of the evaluation indexes of a certain agricultural or industrial supply chain [6][7][8][9], instead of being regarded as a complete supply chain. ere are relatively few studies on water resources as a complete supply chain.…”

Water retailer managed inventory is a classical and inevitable inventory management mode in present economic society. Stochastic models can more clearly explain demand uncertainty and are closely related to water supply chains. Risk preferences are widely valued in behavioral operation management. Related to the risk preferences in inventory management, the research on risk aversion is dominant, while risk-seeking is insufficient. Based on the model assumptions, the risk-seeking retailer’s optimal decision-making inventory model with stochastic demand in a water supply chain is studied. The risk-seeking retailer’s optimal inventory quantity, optimal inventory cost, supplier profit, retailer profit, and the profit of the entire water supply chain are derived. The validity of the equations is proved. The sensitivity analysis of the risk-seeking retailer’s optimal inventory decision-making is carried out. The risk level effects on the five dimensions, the retail price, wholesale price, unit shortage cost, unit inventory cost, and unit residual value, are displayed through numerical simulation. The optimal inventory quantity and optimal inventory cost of the risk-seeking retailer are obtained.
