Adicionar Tag | Resumo: | Rice (Oryza sativa L.), is one of the most important and demanded crops worldwide. In Ecuador is part of the basic diet for most Ecuadorians; in addition, its production is a source of employment for many families in the areas of influence of this crop. Salinization causes negative effects on the physical, chemical and biological properties of the soil. It is toxic to plants and decreases the osmotic potential of soil, causing low yields in crops such as rice. This research details the use of organic amendments as an alternative to reducing the salinity problem in peatlands, concluding that the use of organic amendments can be useful in the management of soils irrigated with saline water, as these amendments demonstrated greater nutrient absorption. Salinity management is focused on using different techniques that seek to minimize the economic and social impact, this is done with the responsible use of agrochemicals and organic products which favor sustainable agriculture. Organic amendments have positive effects on soil and because of their chemical characteristics have good potential for the remediation of sodicity. |
