Soil: a living and strategic resource<\/strong><\/h2>\n\n\n\n
\"\"<\/figure>\n<\/div>\n\n\n\n
\n

Madrid. 07.07.2026<\/strong>.<\/strong> Every 7 July, International Soil Conservation Day<\/a> is celebrated \u2013 a day that serves as a reminder of something essential: soil is not just the surface on which we grow food, but a living, finite and strategic resource. Agricultural productivity, biodiversity, water quality and the resilience of rural areas to climate change all depend on its condition. <\/p>\n\n\n\n

The FAO points out that healthy soils are the foundation of agricultural development<\/a>, food production and numerous ecosystem services. It also warns that soil degradation takes many forms: loss of organic matter, erosion, salinisation, compaction, loss of fertility and deterioration of soil structure. <\/p>\n\n\n\n

In Spain, this debate has a particularly significant dimension for the agricultural and livestock sector. Agriculture and livestock farming generate organic materials with agronomic value \u2014 such as slurry, manure, plant residues and straw \u2014 but their management must be carried out with proper planning, traceability and technical criteria. When these material flows are not managed properly, they can lead to environmental externalities, including emissions, local nuisances and diffuse nitrate pollution. In this article, we will explain best practices for ensuring that soils remain healthy, primarily through the recovery of organic matter for use as energy<\/a> and organic fertilisers. <\/p>\n\n\n\n

An environmental and production challenge<\/h2>\n <\/div>\n
\n
\n

Soil degradation can manifest itself through erosion, loss of organic matter, compaction, salinisation or non-point source pollution. In agricultural areas, this challenge calls for solutions that enable productivity to be maintained without compromising natural resources. It is therefore necessary to move towards models that help the primary sector to produce better, more efficiently and with less environmental impact. <\/p>\n\n \n\n \n \n <\/div>\n <\/div>\n <\/div>\n

From waste to resource: an opportunity for the region<\/h2>\n\n\n\n
\"\"<\/figure>\n<\/div>\n\n\n\n
\n

Agriculture and livestock farming produce organic materials of agronomic value, such as slurry, manure, plant residues and straw. If managed correctly, these materials can become a source of nutrients and organic matter for the soil. <\/p>\n\n\n\n

The right approach is not to single out the livestock sector, but to provide it with technical, traceable and viable solutions. Farmers and livestock farmers play a vital role in soil conservation, as they work directly on the land and need tools that enable them to meet increasing environmental requirements without losing competitiveness. <\/p>\n\n\n\n

\n

The problem is not farming and livestock rearing itself, but the lack of adequate tools to make good use of their organic waste streams.<\/strong><\/h2>\n\n\n\n

Biomethane and digestate to close the nutrient cycle<\/h2>\n <\/div>\n
\n
\n

Biorig\u2019s operations are based on the recovery of organic waste through anaerobic digestion. This process enables agricultural and livestock materials to be converted into biogas, which is then purified to produce biomethane. At the same time, it produces digestate, a stream rich in organic matter and nutrients that can be used as a basis for the production of organic fertilisers. <\/p>\n \n \n <\/div>\n <\/div>\n <\/div>\n
