“…The compost was prepared through controlled decomposition of organic material under aerobic conditions that allowed the event of thermophilic temperature. Compost piles measuring 18 m × 2 m × 1.5 m were designed on-site from locally available eucalyptus wood chips (40%) and sawdust (20%), manure (20%), and cattle manure (20%) stock feed [ 18 ]. The piles were mechanically turned after every 10 days to allow air circulation and homogenizing the compost.…”

“…The maturity of the compost was evaluated on a monthly basis throughout the process by monitoring the temperature with a long probe thermometer to a depth of 0.60 m. At maturity, the compost was tested for toxicity to plants by planting lettuce and onion seeds. The seeds were selected for phytotoxicity bioassay because they have a good response to toxic materials and rapid germination [ 18 ]. Compost samples were collected from four different windrows at three depths using a shovel and tested for phytotoxicity as explained by [ 18 ].…”

Mixing different types of organic matters to form a compound compost can be useful in both short-and long-term improvement of soil chemical properties. However, effects of such composts on soil chemical properties are unknown. A 3-year field study was done to determine the effects of eucalyptus wood-based compost on selected chemical properties of soils at Mooketsi and Politsi avocado orchards, Limpopo Province, South Africa. The study was laid as a repeated measures design with 4 compost treatments at 0, 5, 10, and 15 t ha-1 year-1 with three replicates. Soil pH, EC, organic carbon, active carbon, soil NO3-N, NH4-N, PMN, P K, Ca, Mg, Na Mn, Cu, Zn, and Fe were measured annually at the two orchards after applying compost at the different rates. The eucalyptus wood-based compost significantly (p<0.05) altered the composition of the measured chemical properties at both orchards. The values of the soil chemical properties increased cumulatively with compost quantity and time. This trend was consistent at both orchards. Significantly (p<0.05) highest and lowest values of the soil chemical properties were recorded at 15t ha-1 and 0t ha-1 in 2018 respectively but with no significant (p>0.05) differences between 10t ha-1 and 15t ha-1 compost application rates the entire study period. Eucalyptus wood-based compost raised values of the soil chemical properties at ≥10t ha-1 application rates. It is recommended to apply the eucalyptus wood-based compost ≥10t ha-1 at both orchards, nevertheless, other factors governing organic matter decomposition such as soil temperature were not measured hence further studies are necessary.

Background: The effects of different fertilizer types and their application rates on leaf nutrient content and avocado yield are unclear. An evaluation of eucalyptus-wood-based compost applied at 0, 5, 10, and 15 t ha−1 year−1 on foliar nutrient content, yield, and fruit size distribution (%) was completed at Mooketsi and Politsi, Limpopo Province, South Africa, from 2016 to 2018. Methods: A completely randomized block design with three replicates was used. Data were collected annually, and fruit size was classified as classes; 1 (>275 g), 2 (197–274 g), 3 (148–196 g), and 4 (0–147 g). Results: Leaf N, P, K, Ca, Mg, Fe, Mn, Na, Cu, and Zn, fruit yield and size distribution (%) were significantly (p < 0.05) affected by compost quantity and proportionally increased with application rates in each year. Compost had cumulative effects on the measured parameters; the highest values were recorded in 2018 under a 15 t ha−1 application rate, which corresponded to the highest yield (19.6 t ha−1) and the largest proportion of fruits in class 1. Conclusions: The ≥10 t ha−1 year−1 application rate can be used, though the compost saturation levels of the soils should be determined to avoid possible danger of nutrient toxicity if high application rates are continuously used for >3 years.

“…Su efecto positivo en el rendimiento del palto se atribuye a las ventajas que tiene la incorporación de fuentes orgánicas al suelo, más aún en suelos con bajo contenido de materia orgánica, como el caso de los sistemas en estudio. El beneficio del uso de fuentes orgánicas ha sido descrito ampliamente (Mohale et al, 2021;Campos et al, 2020;Valladares et al, 2020;Kwiatkowski et al, 2020;Burges et al, 2020;Villalva et al, 2015;Tapia et al, 2014;Aguirre et al, 2007;Bruuselma, 2002;Mikkelsen y Hartz, 2008) y va más allá de su valor nutricional, porque mejora las propiedades físicas, químicas y biológicas de los suelos.…”

Perú posee condiciones favorables para la producción orgánica de palto (Persea americana Mill.),lo que ha permitido una importante expansión del cultivo en la última década. Sin embargo, los factores que afectan el rendimiento de palto en sistemas orgánicos han sido poco discutidos. Los objetivos de este estudio fueron describir el contexto físico en el cual se desarrollan los sistemas de producción de palto orgánico y determinar factores técnicos que influyen en su rendimiento en Perú. El estudio se realizó en cuatro distritos de la provincia de Huaura y un distrito de la provincia de Barranca, región Lima, Perú. La descripción del entorno físico se realizó utilizando información secundaria previamente publicada. Se encuestó a productores con certificación orgánica o en transición, proveedores de tres empresas exportadoras. Los registros de cada predio fueron revisados para recolectar información sobre el proceso productivo. La información de cosecha, calidad de exportación y certificación, fue proporcionada por las empresas exportadoras. Predios que usan sistema de riego localizado tuvieron mayores rendimientos que predios que usan riego por gravedad. Los factores que tuvieron alto grado de correlación positiva con el rendimiento fueron las dosis aplicadas de N orgánico, fósforo y potasio (kg ha-1), el número de jornales, y el número de aplicaciones foliares. Es necesario mejorar significativamente el manejo técnico del cultivo, para incrementar el rendimiento y calidad de fruto.
