“…According to Delgado et al [28], cover crops are key tools that could contribute to increased yields, conservation of surface and ground water quality, reduced erosion potential, sequestration of atmospheric carbon and improved soil quality and health. Cover crops are usually leguminous plants which form branches and twine over and essentially cover and screen the land from direct atmospheric impact from sunlight or rainfall.…”

Agriculture is crucial to the survival and well-being of the populations of most nations. It is the single most important means of livelihood and foreign exchange earnings for many nations globally. Crop Production is the bedrock of agriculture on which most other agricultural activities depend, because of the ability of plants to manufacture their food via photosynthesis, which is an essential phenomenon for the sustenance of the natural system. Thus, most other agricultural activities depend directly or indirectly on crop production. As a result of the exponential increase in world population, leading to a significant reduction in agricultural land due to urbanization; deforestation, air pollution, erosion, climate change, and consequently, food insecurity; measures must be put in place to ensure crop production intensification via sustainable and environmentally safe methods that guarantee food security. The principles of sustainable crop production intensification discussed in this Chapter include optimum tillage method, land and water resources management practices, suitable choice of agricultural system, precise crop management techniques, and bioremediation, in an already contaminate environment.

“…Among reforestation planting attributes, the provision of a more friendly environment to support the growth of higher plants is critical. Planting cover crops has immediate benefits in that they cover the soil surface, improve soil characteristics and protect the soil from erosion [86][87][88][89], reduce soil compaction [90,91], improve hydraulic conductivity, increase soil porosity [92], and enrich soil organic matter and macro-and microelements [93]. These crops further create a favorable environment for the growth and diversity of soil microbes [94].…”

Tropical forests are among the most diverse ecosystems in the world, completed by huge biodiversity. An expansion in natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices are needed as an effort to reclaim their function. This paper summarizes the existing practice of coal mining, covering the regulatory aspects and their reclamation obligations, the practices of coal mining from various sites with different land characteristics, and the reclamation efforts of the post-mining landscapes in Indonesia. The regulations issued accommodate the difference between mining land inside the forest area and outside the forest area, especially in the aspect of the permit authority and in evaluating the success rate of reclamation. In coal-mining practices, this paper describes starting from land clearing activities and followed by storing soil layers and overburden materials. In this step, proper handling of potentially acid-forming materials is crucial to prevent acid mine drainage. At the reclamation stage, this paper sequentially presents research results and the field applications in rearranging the overburden and soil materials, controlling acid mine drainage and erosion, and managing the drainage system, settling ponds, and pit lakes. Many efforts to reclaim post-coal-mining lands and their success rate have been reported and highlighted. Several success stories describe that post-coal-mining lands can be returned to forests that provide ecosystem services and goods. A set of science-based best management practices for post-coal-mine reforestation is needed to develop to promote the success of forest reclamation and restoration in post-coal-mining lands through the planting of high-value hardwood trees, increasing trees’ survival rates and growth, and accelerating the establishment of forest habitat through the application of proper tree planting technique. The monitoring and evaluation aspect is also crucial, as corrective action may be taken considering the different success rates for different site characteristics.

“…Se debe tomar en cuenta que los requerimientos hídricos de la quinua señalados por Garcia et al (2003); Geerts et al (2008); y Aguilar & Jacobsen (2003) fueron calculados en un sistema de monocultivo; para nuestro caso será también importante conocer en el futuro el valor combinado de la evapotranspiración de la quinua y su cobertura viva en convivencia durante toda una campaña. Al considerar la distribución de las lluvias en nuestro experimento, resulta que el 68% de estas se concentraron entre diciembre, enero, y febrero (Figura 2), lo que indica una distribución regularmente homogénea que coincidió con la floración y el llenado de grano de la quinua, que son fenologías claves en las que se debe evitar el estrés hídrico para no tener una importante disminución en el rendimiento (Geerts et al, 2008;Malhi et al, 2021;Delgado et al, 2021) Figura 3. Peso seco de las biomasas de las coberturas (peso medio ± desviación estándar) en las localidades de Patasucro, Qaqas, y Ccanis.…”

El uso de coberturas puede traer múltiples ventajas a los sistemas de producción agrícola y a las propiedades de los suelos. El objetivo de este trabajo fue evaluar en un sistema con agricultura de secano, el efecto a corto plazo del trébol (Medicago hispida G.) y la arveja (Psium sativum L.) como coberturas vivas en la humedad del suelo y el rendimiento de la quinua, en las localidades de Patasucro, Qaqas, y Ccanis de Ayacucho, Perú. El experimento se condujo bajo un diseño de bloques completos al azar, se empleó como tratamientos al trébol, la arveja y un testigo sin cobertura. La comparación de medias se realizó mediante la prueba de Tukey (α 0,05). Con respecto al rendimiento, solo existieron diferencias significativas en la localidad de Qaqas, donde las coberturas superaron al control por 0,4 t ha -1 (trébol) y 0,29 t ha -1 (arveja). La humedad del suelo fue significativamente mayor en el trébol en las localidades de Qaqas y Patasucro, superando al control por 3,97% y 1,02%, respectivamente; la arveja y el control no presentaron diferencias estadísticas. Se sostiene que las mejoras en el rendimiento ocurrieron debido a la conservación de la humedad del suelo generada por el efecto de sombreamiento de las coberturas.Palabras clave: sistema de secano; cultivos de cobertura; humedad del suelo; quinua.
