The objective of the study was to evaluate some biological properties of the soil in an agroforestry system with <em>Morella pubescens</em> intercropped with <em>Smallanthus sonchifolius</em> and in a degraded pasture of <em>Cenchrus clandestinum</em>. The trial was conducted at the Botana Experimental Farm, Nariño, at 2,820 meters above sea level. Density, richness and Simpson and Shannon-Wiener diversity indices were determined. A Randomized Complete Block Design with three replications was used. The treatments corresponded to sowing distances of <em>S. sonchifolius.</em> T1: sown at 1x1m, T2: 0.8x0.8m, T3: 0.5x0.5m and the control T4 corresponded to degraded pasture of <em>C. clandestinum</em>. The tree component <em>M. pubescens</em> was established at 4x4m between seedlings and 9m between rows. Soil macrofauna sampling was carried out following the monolithic TSBF method, collecting at depths of (0-10, 10-20 and 20-30cm). A total density of 6,496i/m2 individuals was found. The highest value was obtained in T3 (3,168i/m2) represented by the taxonomic groups Diptera and Haplotaxida. Higher values of richness were observed in T1. The Shannon index was higher in T2 (0.66) while T1 (0.80) presented higher dominance in morphospecies. Density and richness were higher in the agroforestry arrangement than in the degraded <em>Cenchrus clandestinum</em> pasture. Treatments, depth and their interaction did not significantly affect morphospecies diversity.</p> 2024-01-18T00:00:00+00:00 Copyright (c) 2024 Revista de Ciencias Agrícolas https://revistas.udenar.edu.co/index.php/rfacia/article/view/8241 Use of silicate amendments on Improvement of the quality and nutrition of the potato crop, variety 'Diacol Capiro' 2023-08-31T01:20:08+00:00 David Fernando Torres-Hernandez mollisol89@hotmail.com Elberth Hernando Pinzón-Sandoval elberth02@gmail.com Helber Enrique Balaguera-López hebalagueral@unal.edu.co Amanda Silva-Parra asilvap@unillanos.edu.co Pedro Jose Almanza-Merchán pedro.almanza@uptc.edu.co <p>Potato (<em>Solanum tuberosum</em> L.) is one of the most important agricultural products in cold-climate areas of the world. However, the soils intended for potato production in tropical zones such as Colombia have low availability of essential elements, such as phosphorus, calcium, magnesium, and beneficial elements such as silicon. The general objective was to evaluate the application of increasing doses of three silicate amendments on the dynamics of accumulation of phosphorus, calcium, magnesium, and silicon in leaf tissue and their influence on the quality and production of 'Diacol Capiro' potato tubers under the conditions of Soracá municipality, Boyacá-Colombia. Two production cycles were evaluated, with a completely randomized design and 10 treatments in each cycle. It was observed that the application of double calcium and magnesium silicate at a dose of 900 kg ha<sup>-1</sup> as a crop management practice resulted in an increase in the accumulation of macronutrients such as P, Ca, and Mg by 63.1, 32.4, and 51.1%, respectively, and a 100% increase in silicon accumulation as a beneficial element; this was reflected in a 46% increase in total yield, with a higher production of first-quality tubers and a significant increase in dry matter and specific gravity compared to the application of conventional fertilization sources. Therefore, silicate fertilizers are an important alternative to improve quality and production through a better dynamic of accumulation of essential and beneficial nutrients in potato-producing areas in Colombia.</p> 2014-01-26T00:00:00+00:00 Copyright (c) 2024 Revista de Ciencias Agrícolas https://revistas.udenar.edu.co/index.php/rfacia/article/view/7219 Assessment of transitory crops in cocoa (Theobroma cacao L) agroforestry in Páez, Boyacá 2022-02-17T09:48:00+00:00 Lindays Alfonso-Alfonso lindays.alfonso@uptc.edu.co Laura Dayana Escobar-Pachajoa ldescobarp@agrosavia.co Felipe Montealegre-Bustos fmontealegre@agrosavia.co Fabricio Eulalio Carvalho fcarvalho@agrosavia.co Albert Sneyder Carvajal-Rivera acarvajal@agrosavia.co Jairo Rojas-Molina jairo.rojasmolina@gmail.com <p>Agroforestry systems incorporate several productive components per unit area to yield efficiency. However, considering the high degree of complexity inherent to interspecific plant-plant interactions, little is known about most of these systems' real productive potential and efficiency. In this context, it is important to analyze the interactions between the components to identify potential favorable associations. The objective of this research was to evaluate the performance of the transitory crops maize (<em>Zea mays</em> L) and cowpea (<em>Vigna unguiculata</em> L) in a family farming system under three agroforestry arrangements with cocoa in the municipality of Páez, Boyacá, Colombia. A split plot design was used, where the main plots corresponded to three shade forest species, which were associated with cocoa and the transient crops. The subplots corresponded to three planting systems: CS1cocoa+maize, CS2 coca+beans and CS3 cocoa+maize+beans. The effect on agronomic and productive traits of transitory crops (maize and beans) was evaluated, and an economic analysis was carried out. For beans, the effect of the cropping system on yield (t. ha-1) stood out, while for maize, the statistical effect was given by the forest x cropping system interaction in most of the variables evaluated. Considering the interspecific interactions found under the influence of different forests, the use of Colombian mahogany as a companion species in these intercropping systems is suggested. The cost analysis revealed that the maize-bean association is more efficient in the equivalent use of land. Therefore, the data obtained reveal more efficient strategies for sustainable cocoa productivity in Colombia.</p> 2024-02-15T00:00:00+00:00 Copyright (c) 2024 Revista de Ciencias Agrícolas https://revistas.udenar.edu.co/index.php/rfacia/article/view/8272 Soil physical properties as indicators of histosol degradation in Colombia 2023-09-15T23:22:26+00:00 Ricardo Javier Aguillon-Estacio ricardoaguillon2020@itp.edu.co Irene Alejandra Muñoz-España irenemunoz2020@itp.edu.co Adriana del Socorro Guerra-Acosta aguerra@itp.edu.co Adriana Bolívar-Gamboa adriana.bolivar@uptc.edu.co Elberth Hernando Pinzón-Sandoval elberth.pinzon@uptc.edu.co <p>Changes in soil utilization exert detrimental effects on its properties, emphasizing the critical need for a thorough evaluation to mitigate their repercussions on the ecosystem. This investigation was conducted aiming to assess the physical degradation in histosol soils in the Putumayo department, Colombia, caused by alterations in land use. For this, we assessed two types of areas: those without intervention (T0) and those affected by deformation in mound structures caused by the combined actions of livestock and high moisture, commonly known as “tatucos”. The assessment categorized these areas based on the percentage deformation incidence: low degradation (T1), moderate degradation (T2), and high degradation (T3). Sampling was conducted at a depth of 15 cm, both in the tatuco-affected zone and its surrounding area. Measurements were taken for mound height and diameter, as well as physical properties such as bulk and real density, porosity, volumetric moisture, penetration resistance, and the degree of organic material decomposition. The primary land use identified in the study area was extensive livestock farming. It was established that in areas with high levels of degradation (T3), there was an average mound diameter of 151.9 ± 4.46 cm and a height of 22.7 ± 2.59 cm. Regarding physical properties in the area adjacent to the mound, there was a bulk density of 0.24 g.cm<sup>-3</sup>, a real density of 1.62 g.cm<sup>-3</sup>, and a penetration resistance of 0.71 MPa. These values were significantly higher than those observed in areas without intervention. Hence, it can be inferred that the alteration in land use is causing a substantial change in the physical properties of these soils, which are vital for the agroecosystems in the southern regions of Colombia.</p> 2024-03-18T00:00:00+00:00 Copyright (c) 2024 Revista de Ciencias Agrícolas
