“…El 44 % de los productores agrarios de Churuzapa tiene entre 40 y 49 años de edad; el 31 % tiene entre 33 y 39 años de edad; el 25 % tiene de 50 a más años de edad (figura 1). El 75 % de los productores tiene edad por debajo de 65 años, situación capital en la planificación tecnológica agraria; pues, por ejemplo, la agricultura de precisión (AP) se subraya como una representación creadora de tramitar los recursos productivos, acrecentando la eficiencia y la sostenibilidad socioeconómica y ambiental de los regímenes agrícolas (Cherubin et al, 2022).…”

El objetivo de la investigación fue registrar el estado en que se encuentran las cuestiones sociales, productivas y ambientales de la comunidad de Churuzapa, Lamas, como referente de otras comunidades similares. Para las valorizaciones productivas de las parcelas, las informaciones fueron proporcionadas por los productores, mediante fichas y encuestas. Para las valoraciones de servicios ambientales de biomasa y captura de carbono de las parcelas, se realizó trabajo de campo, en las parcelas de los mismos productores encuestados, registrando el peso de la biomasa seca; el carbono total y la densidad aparente de sus suelos. En asamblea comunal, en la plaza pública, las autoridades informaron a la comunidad, la ejecución del proyecto de investigación; entonces, en el mismo acto, de manera voluntaria, los dieciséis productores se inscribieron, para formar parte del estudio. Los resultados arrojan que, la edad promedio de los productores es 46 años. La superficie promedio de las parcelas es 2,51 hectáreas. El 81 \% de las parcelas tiene título de propiedad. El peso seco de hierbas es 1573 kg ha-1. El peso seco la hojarasca de diversos cultivos es 926 kg ha-1. El estado socio económico ambiental actual de las parcelas agrarias de Churuzapa tiene S/.2126975 soles ($574858 USA; t.c: 3,7). Utilidad promedio de cultivos: arroz 7,37 %; cítricos 19,9 %; plátano 30,1 %; frijol 0,12 %; yuca 26,3 %; maíz 18,6 %; frutales 45,7 %, con 21 %. En circunstancias de financiamientos productivos a dichos cultivos, con 12 \% de Tasa social de Descuento (TSD), la TIR bordea el 20 % que, sería el porcentaje de beneficio o pérdida que conllevaría dicha inversión. No existe diferencia significativa entre la valoración productiva con el estado socioeconómico en parcelas agrarias de Churuzapa (p>0.05); asimismo, la valoración positiva no se relaciona mucho con el estado socioeconómico ambiental, debido a que solo se está relacionado con una parte de la producción económica de cultivos, mas no con los demás factores; pues, el grado de correlación entre ambas variables es 0,286; que es positiva baja. Pero, tampoco existe diferencia significativa entre la valoración ambiental con el estado socioeconómico en parcelas agrarias Churuzapa (p= 0,036); la valoración ambiental del carbono solo se está considerando como referencia, aunque el grado de correlación de Spearman se muestra significativo (0,786), demostrándose que, están relacionados la parte ambiental con el estado socioeconómico de Churuzapa.

Agrochemicals play a vital role in modern agriculture, aiding in crop protection and enhancing yields. However, their use can have significant environmental implications, particularly regarding soil and water quality. This review explores the geologic considerations in agrochemical use, focusing on impact assessment and guidelines for environmentally safe farming practices. The geologic factors influencing agrochemical use are multifaceted. Soil composition and structure affect the retention and leaching of agrochemicals, impacting their availability to crops and potential for environmental contamination. Geological processes, such as erosion and sedimentation, can transport agrochemicals to water bodies, leading to water pollution. Understanding these factors is crucial for assessing the potential impacts of agrochemical use on the environment. Impact assessment of agrochemical use involves evaluating its effects on soil, water, and ecosystems. Techniques such as soil and water sampling, geophysical surveys, and remote sensing can help assess the distribution and movement of agrochemicals in the environment. This information is essential for developing guidelines and management practices to minimize environmental impacts. Guidelines for environmentally safe farming practices aim to reduce the use of agrochemicals and mitigate their impacts. Practices such as integrated pest management, conservation tillage, and precision agriculture can help minimize the need for agrochemicals and enhance soil health. Additionally, proper storage, handling, and disposal of agrochemicals are essential to prevent environmental contamination. In conclusion, geologic considerations play a crucial role in assessing the impact of agrochemical use on the environment and developing guidelines for environmentally safe farming practices. By integrating geologic factors into agricultural management practices, farmers can reduce the environmental footprint of agrochemical use and ensure the long-term sustainability of agricultural systems.

“…Recent data have shown that soybean production reached 388.01 million tons in the 2022/2023 season, representing an increase of approximately 7.7% compared to the previous harvest (Statista 2023). The strong demand from the global market is one of the factors driving large-scale production (CONAB 2022), and farmers meet this need through expanding cultivation areas, increased use of fertilizers, advanced machinery and precision agriculture technologies, as well as an increased application of pesticides for crop disease management (Cherubin et al 2022).…”

Aims Bioformulations with Trichoderma strains offer cost-effective and sustainable options for integrated disease management and plant nutrition. Therefore, this study aimed selected new isolates of Trichoderma with antagonistic and plant growth promotion abilities, including the effect of inoculation of isolates on the early development of soybean seedlings. Methods Trichoderma isolated from the soybean rhizosphere were screenings assessed their antagonistic activity against three phytopathogens, as well as their capability for indole-3-acetic acid (IAA) synthesis and phosphate solubilization. Three promising isolates were further examined for their tolerance to various in vitro conditions and agrochemicals. Single and co-inoculation experiments to assess their effects on growth, chlorophyll, carotenoids, proteins, flavonoids, and phenolic compounds during early soybean development. Results T. viride GT-8, T. reesei GT-31, and T. longibrachiatum GT-32 demonstrated antagonism against phytopathogens. GT-31 and GT-32 exhibited higher IAA synthesis (175.8 ± 2.4 µg/mL and 119.6 ± 11.2 µg/mL, respectively), while GT-8 showed superior phosphate solubilization (28.56 ± 0.4 µg P/mL). All three fungi displayed robust growth under various conditions and agrochemical treatments. Trichoderma inoculation significantly enhanced shoot and root growth, with co-inoculation resulting in even higher dry shoot and root weights, increasing by 50.3% and 48.8%, respectively, compared to non-inoculated seedlings. Trichoderma-inoculated plants also exhibited elevated chlorophyll, carotenoids, flavonoids, and phenolic compounds. Conclusion Overall, these findings highlight the potential of these novel Trichoderma isolates for formulating bioformulations that can enhance plant growth and offer benefits in soybean crops, providing a sustainable strategy for agriculture.
